KAMIKAZ: Randy’s 1970 Datsun 240z

Filed under: 240z,Featured Cars and Projects
by Alvin G @ 1:51 am on March 21, 2020


Randy Jaffe is an avid car guy and Datsun enthusiast. Beyond his fanatic attention to detail and love for Nissan racing he’s excessive–in the best way possible and we love him for it.  Several years ago we teamed up with Randy to turn his BRE Datsun 240z show car into a competitive vintage road-race car.

 

He was impressed with our work on the BRE Z and told us about another Z project that he was working on but stalled out in Atlanta.  We decided it was time to finish this ultimate track/street car with a healthy dose of his personality. The highlight of this Series 1 240z is a full Rocketbunny body kit with plenty of Z Car Garage touches. Let’s take a closer look at the build:

 

Origins

The creation of the Rocketbunny Z changed courses many times as the build evolved, as Randy recalls:

“I wanted to build a series 1 Radical fun Street car with a completely different look. We started off thinking we would do conventional flares and conventional displacement for a 240 Z. Then my painter Bryson was doing the bodywork and had just installed a Rocketbunny kit on a 350Z and asked me to take a look at that particular body kit. I knew of the first one completed by Sung Kang and I think it was the second or third kit to come to the country when we ordered it from Japan directly.”

 

“The paint color which originally was going to be Porsche’s lava orange evolved because of Michael Eberhardt to Porsche‘s late 60s color called Tangerine. Tangerine painted with a white sub-coat pops where Helen Keller could see the color! Since I am color blind, the brighter the color the better I can see it.  Bryson welded an amazing full roll cage as I decided to create the car as a street and track beast.”


The body was amazingly painted and caged by Bryson of Classic Livery of Atlanta. They are known for many high-end commissions including several RWB Porsche’s for Akira Nakai. Randy’s transporter trekked from Atlanta to drop off this gorgeous chassis at ZCG and our work began.

Assembly Required: Race Chassis Prep

 

The chassis was temporarily mounted on rollers while we prepped suspension pieces. Following the “race-car for the street” theme, we re-created the entire front and rear BRE 240z suspension setup. Everything that the #46 race car has is on this street car from DP racing front/rear struts, koni shocks, identical spring rates, sway bar, adjustable end links, plated finish…all of it. More pictures in the gallery below!

Front and rear:

 

Z Car Garage Big-Brakes

There are two versions of our ZCG Big Brakes  and the only three “racing” setups on are on the BRE car, Alex’s Hako and the Rocketbunny Z:

 

Stay tuned for our latest big-brake upgrade from the minds of ZCG and Stoptech!

 

Back to the chassis, the entire hydraulic system was installed starting with freshly plated lines.

Z Car Garage CV Axles

Z Car Garage is proud to offer a CV axle conversion kit for Datsun S30 and 510 cars. We run these on our race cars and the Rocketbunny Z also got a set.

 

Helping put the power down effectively is an OS Giken limited-slip R180 diff properly set up in-house by Joshua Corwin.

 

Wheels Make The Car

 

The biggest hurdle on this car was wheel choice.  Wheels can make or break the car and they had to befit the “KAMIKAZ” nickname.  There was no way we would have a car with massive flares and not use every single square inch of real estate available to fill with wheel and tire.

 

We sourced some Panasport C8 centers and began a custom build with MemoryFab who was instrumental in helping us with fitment/barrel sizing. Up front are 17×10 with a 275/35/17 tire and 17×12 rear with 335/35/17 tire (NT-01R). At the time there were no other RB cars running a 335 in back! .

 

We spent many hours making the kit fit around these wheels/tires so there was no rubbing:

 

Everyone was pleased with wheel choice for KAMIKAZ, especially Randy:

“I had already ordered and received a set of Watanabe wheels from Japan however they would not work with the rocket bunny kit so when I sent the car to Rob Fuller at Z car garage he did his magic and created a set of custom wheels using a set of Panasport racing C8 NOS wheels. 10 inch wheels on the front 12 inch wheels on the back by 17s gives the car and unreal stance.”

 

Race Engine

 

We had Rebello build a nasty 3.2L for the Z running triple-Mikuni’s, 12:5:1 compression (110 leaded fuel) backed by a 280zx 5-speed. Randy gave us a blank canvas to assemble the entire car but ZCG touches really shine in the engine bay.

“I basically wanted my 46Z race car for the street and asked Rob Fuller to further tap into his magic box so we built a 3.2 race motor full race suspension and the whole 9 yards! Rob and his guys built an amazing car using special finishes on some of the metal work under the hood and the car is just insane to drive.”

Here are a few pictures of the assembly with many more in the gallery. Aluminum flywheel with twin-plate setup and comp oil pan just like BRE car:

 
 

Triple Mikuni induction:

 

Engine going in and detail work beginning. We re-created the cooling system from the BRE car and ran all of the chassis wiring.

 

The catch can, radiator and Datsun roadster overflow are all period parts that BRE used and duplicated for the Rocketbunny:

 

 

Interior

With drivetrain and chassis sorted we moved to the interior. Continuing the race car theme is a stripped (but pretty) body-color interior with that beautiful roll cage from Bryson.


The dash was covered in Alcantara. We installed and wired it up with period gauges. All switch gear similar to the BRE car:

Enter the JGRBOMB

 

This was our quickest build to date so we could make a debut at the 2018 Japanese Classic Car Show in Long Beach, CA. The night before our roadtrip down to SoCal we applied a Jagermeister livery to the car. Randy’s inspiration came from his obsession with Porsche, and the Max Moritz Racing Porsche 934:

 

“I love race liveries and told the guys at the car garage I wanted to do the Jagermeister racing package on this car and they were not really hip to it but Bryson and I discussed it several times and we both thought it would take the car to the next level.  However I stuck with my gut and flew out to San Jose with the livery kit a few days before JCCS and after the first hood decal Rob and his guys were scratching their head thinking hmmm – This may not be a bad idea LOL.”

 

Rob and I finished applying the decals late in the night before going to Long Beach and we received a lot of positive feedback at that show and then the car came back to ZCon in Atlanta and won a Gold Cup award. The car was also shown at SEMA in 2018 where again the car received an immense amount of positive feedback.”

Indeed, the livery on the Rocketbunny (KAMIKAZ) Z looked fantastic and Randy eventually affixed the JGRBOMB license plate to match. We are happy to report that while at JCCS  Randy’s Z won 1st place, Best 240z in a class filled with incredible Z cars!

 

It was also well-received at Z Con and the SEMA show (thanks to Gary and Braille!). That’s BRE front-man Peter Brock and the designer of the Rocketbunny body kit, Kei Miura both signing the Z:

 

 

That BRE Exhaust


We wanted to do a BRE exhaust so we used the Fujitsubo headers and a straight twin-exit with megaphones exactly like the BRE original set up, Randy notes the white color:

 

“Of course BRE had theirs painted yellow from day one and still are but I wanted to do the rocket bunny exhaust megaphones in white to play off the livery. Many vintage race cars have white headers and exhaust so it made sense to me. So the audio level is the same as the 46Z and will wake up the dead.”

 
 

How does it sound? Check out this short video with a dyno run, enjoy!

 

 

Details


It would take multiple blog posts to cover all the special details throughout this build. Some highlights include fully polishing all trim pieces like quarters, drip rails, etc. Re-keying locks. Even the mirror was done to Randy’s liking.


Things like the differential temperature gauge behind the old gas fill door have a purpose and pay homage to the Datsun vintage race cars. Contrastingly, there are small modern updates like vintage H4 headlights retrofitted with HID units.


We asked Randy what’s it like to drive:

“To me there’s no difference in driving this and the 46Z it’s almost the same build except more rubber on this one!”

To us that is a great compliment because we set out to finish Randy’s vision of the ultimate street/track BRE-flavored Z.

I find myself several nights a week just walking around the car in my shop and admiring the build that Rob, Josh and the crew at Z Car Garage created.”


We thank Randy for letting us be creative on this Z and it’s been rewarding to see his taste reflected in other builds. This was a fun project and we enjoyed every moment of it. Browse the extensive photo gallery and LONG LIVE THE Z!

Datsun 2000 Roadster Wins Concours!

Filed under: Automotive History,Events
by Alvin G @ 10:30 pm on February 16, 2020

 

We are happy to report a Best In Class win for this 1967 Datsun 2000 at the 2020 Boca Raton Concours D’Elegance in Florida. Typically reserved for European and American marques, Concours events rarely accept Japanese classics to enter and compete on the same field, let alone a Datsun.

 

Acquired by noted marque expert Mike Young several years ago, owner Steve Tetreault took it upon himself to bring the rare Datsun 2000 roadster to concours-level status. Steve recalls how his Datsun was even considered for the event:

“After hearing about the Boca Concours in April of 2019- I decided to submit an application for the Datsun. I soon realized the category that I would be in was named “European Class Sports car” ’65-’75. I completed the application and submitted photos as required in June 2019 and asked the question, “Where does a Japanese car fit here?” In October of that year I received an email requesting more information about the significance of the car, and a few other questions, including more detailed photos”

Steve soon received an email from the nominating committee that he was in fact in the Concours! The class name had been revised to: “Foreign Sports Late” 1965-1975. He was in good company as well:  *1966 Lamborghini superleggero *1965 Porsche 356 cabriolet *1967 Jaguar XKE *1974 Alfa Romeo Montreal *1971 Mercedes 280SL pagoda *1970 Ford Capri Perana *1967 Datsun 2000 Sports

 

Steve describes his Concours experience:

“The 3 very astute judges asked to be left alone while they surveyed the exterior- top up windows up. They asked to see the engine room , open the doors and to explain the significance of the car and why I am showing it. I explained the rarity of a half year car, and that this car is #455 out 750 produced with factory options of 5 speed trans, Mikuni/Solex carbs, B cam, 7 quart finned oil pan, 4 bolt windscreen, and then referenced John Baker’s race credentials for Nissan. I completed the conversation with my true mission: To elevate the Datsun Marque and its ability to compete equally in any Concours D Elegance class such as the one I’m in.” 

 

 

To be considered for a Concours and then go on to WIN best in class amongst impressive peers is an incredible achievement for Steve. All Datsun owners can share and benefit from this breakthrough as well: it’s a sign that our cars are being taken seriously and command respect.  So kudos to your efforts Steve. We remember seeing your roadster at the Solvang Shows and now it is a superb ambassador! Here is SRL-0455 after a 6-month restoration by Steve, sporting vintage Enkei Comp 8 wheels, #665 Paint and fresh chrome:

The fifth annual HSR Classic 24hr race at Daytona International Speedway was held November 13-17. Racing legend John Morton and co-driver Rob Fuller piloted the #46 BRE Datsun 240z owned by team manager Randy Jaffe.
.

Enjoy our report from the event with pictures, video and commentary from Rob and Randy!

 

Hallowed Ground: #46 Debuts at Daytona Speedway

 

When the BRE 240z was not accepted into the 2019 Rolex Monterey Motorsports Reunion team owner Randy Jaffe was anxious to find a Fall event. Thanks to Michael Eberhardt of Vintage Racing Co. we were able to run the Classic 24 and share a garage with him at Daytona. It was an amazing feeling sharing the same hallowed grounds where all the pros raced for years.

 

Rob: “This is a relatively new event and HSR’s efforts to make it larger were clear: the Classic 24 had people from all over the world (1/3 from Europe), and famous drivers and cars everywhere: Gunnar Jeannette, Derek/Justin bell, Jochen Maas, Daytona prototypes, LMP cars, vintage IMSA cars, 935s and big-boy hardware.”

Paddock pictures from top left to bottom right: AC/DC lead singer Brian Johnson with Rob Fuller, Gunnar Racing Team, VM columnist Jochen Maas and a 1955 300SL, 1985 Porsche 962 HR1 piloted by team of Derek Bell, Justin Bell, Rodrigo Sales, and Gunnar Jeannette.

 

Enjoy this video of the sights and sounds at Daytona:

 

Racing at Daytona

    
 

The Classic 24 race features six race groups with 4 (1hr) sessions and cumulative time deciding the winner. Each session has a 3-minute pitstop with mandatory driver exit during fueling. There were many challenges facing the ZCG team as we prepped the BRE 240Z for big banking of Daytona:

Rob: “Josh Corwin prepped gear ratios for the diff and we went there armed for any scenario. At 3.56 miles, Daytona is much longer than our West Coast tracks so we built a 3.54 and 3.36. After one practice session we realized the 3.36 was needed.”

 

It was an incredible sight to see the #46Z out on the high banking with serious race cars like the Smith Motorworks 1980 Porsche 935 K3:

 

To aid driving during night sessions the Z was fitted with LED lamps:

 

Despite heavy rain the team carried on, making changes to the car and improving with each session.

Rob:  “There were 12 cars in our group with a bunch of 911s and 914s. The Z worked flawlessly.  We made a last minute carb change, sent pics of the spark plugs to Dave Rebello, and we were pumped for it. The sheer size of the stands and banking was overwhelming but we welcomed the challenge!”

Randy:  “As you drive into the infield at Daytona and look at that 31% banking it’s super intimidating and as Rob stated you cannot look straight out of the car as it’s always bending left and he has never experienced that before. Rob did an amazing job of adapting to not only the car but to the track within 2 to 3 laps as he had cut down six seconds plus. John Morton has not run Daytona in over 20 years and he got right in the car and turned a great time which is what professional race drivers do! At 77 years old it’s just amazing how he is so calm and so smooth around these tracks!”

 

Remember those those mandatory pitstops? Thanks to the ZCG team (Josh/Keith) all stops were nailed and we actually had to wait because we were under time.  We also had help from Randy’s friend Barney to help with fueling, and Chris Karl from SCCA. A rally of people excited to see the Z at Daytona all pitched in.

 

The bad weather and lack of track experience didn’t hold John or Rob back. We started 10th in class in the 1st session and by the end of the 1st leg we were in 3rd place.

 

From 10th to 3rd in one session is impressive with John and Rob turning near-identical lap times. Rob was ecstatic not only about the Z’s performance, but also being able to co-drive with his hero:

Rob:Ben from Retrosport with Alan Terpins’ 1979 Porsche 935 MOMO car kicked ass and won their class.  They were clocked on the front straight under braking at 188mph. The BRE Z did 156mph top speed and our lap times (Morton and Fuller) were within a .1 of each other. I can’t describe the feeling of going from total fanboy to being a co-driver with John Morton. All of this comes from Randy Jaffe’s generosity, drive/passion to celebrate this car and era. These heroes that were making history and didn’t even know it 50years later. All while a new crop of people that love and appreciate this car. Watching people from all over the world come over to find John Morton to have him sign something, shake his hand, tell him a Datsun story. It’s surreal.”

 

Unfortunately our hopes of a first or second place finish in class were cut short at the second session. John Morton got an epic start and as they all went into turn 1 on the first lap (at night) a Lola T 70 lost its grip, then a Chevron panicked and cut hard right in front of John. There was nothing he could do and the car was so low that it flipped us up in the air and onto the roof:

 

John Morton was able to exit the Z safely, without any injuries. The Z was towed in, covered and our race ended. We all had hashbrowns and coffee late night at Waffle House. The next morning Josh and Rob set the tow on the front of the car, took plugs out and turned it over. We actually got to drive it around paddock Sunday morning, knowing we would be back again to take a run at the high banks of Daytona.

Randy: “Most historic race cars have been wrecked so many times and put back together and we will do the same after this Daytona accident. Just a slight bump in the road but we will come back stronger as we have learned and we will continue to write more current history with John at the wheel. We can’t wait until Daytona next year where Rob and John can finish the 24 hour that we started this year.”

Here is a video with in-car footage of both John Morton and Rob Fuller. Enjoy the triple-Mikuni carb’d music and wild banking of Daytona!  At the end is multiple-angle footage of the crash:

 

The BRE 240Z will be rebuilt at Z Car Garage

 
 

We welcomed back the #46Z to ZCG for a rebuild after damages from the Daytona crash. Stay tuned for progress updates:

Randy: “The car is being shipped to Z car garage on December 13th for repairs and to prep the car for the Walter Mitty races in Atlanta in April. The most amazing part of the fun we’ve had with this car over the past three years is the excitement that Peter Brock and John Morton have shared with all of us to turn back the Hands of time! I think because of social media John Morton may actually be more famous now than he was back in the day and he often thanks me for the efforts to make his accomplishments recognized over and over which he certainly deserves! What 77-year-old race car driver do you know still flies airplanes and rides dirt bikes, jeeps and works out!! Of course none of this would happen without Rob Fuller and Josh Corwin they have been the glue behind us entire program and I would’ve never done any of this without them. Rob takes control of many situations that could be stressful and makes things easier for me!”

 

At 77 years of age John Morton is still formidable behind the wheel!

 
 

Randy was and continues to be supremely enthusiastic about the Z, John Morton and BRE. His words from Daytona:

“Per usual our pit area always had fans coming up and wanted to know where John was to talk to him and get an autograph as he had raced with many of these legends for the past five decades! I really love the story about Peter Brock and the BRE team and what John accomplished in a short period of time and still lives in high racing lore! Every piece of history from this time s fun for me to gather and collect as all of it is a part of the story!”

Randy and the BRE 240Z Build

While many have seen the BRE 240z at racing events and shows, there is a great story behind this car as told by owner Randy Jaffe:

“I met John somewhere around 2012 and told him I was going to build a tribute to his championship 240 Z car and I’m sure he’s heard that hundreds of times and he was kind of bored with the conversation. Then I started sending him and Peter Brock emails to build it correctly then after I spent several years at an attempt to do a tribute I was with both of them one night and asked about the real story on the remains of the original car. Both of them looked at each other and back at me and I was like – what was that look for? They went on to tell me that the story I had heard for years about the car being totally destroyed and no longer around was not true. Dan Parkinson who lived about a hour and a half north of Los Angeles had the remains of the car that he had re-bodied after a 1977 ball joint failure at phoenix motor Speedway. Casey Mollett – another Datsun racer back in the day was a few hundred yards behind Dan Parkinson when he hit that wall and he was part of the teardown and reassembly to the 1977 to 80 Z that Nissan gave Dan to rebuild a car. They were going to repair the original 46Z which now wore the number five livery of Dan Parkinson but the painter said it would take a month and a half to two months and they had to race in a few weeks so they use the 1977 280 Z that Nissan gave Dan.”

 

“The long and short of it is that they raced the 1977 shell for a few years and retired the car and racing in 1979 and all of those parts just sat there until 2016. Dan and I have had conversations for over a year and many many people were trying to buy these parts because they knew what they were but for some reason he felt comfortable and asked me one day do I really want all the stuff and of course I said yes. John Morton actually said since he owned the original chassis plate which he had taken off the car when he installed the remote Traco oil filter back in 1970 he kept that Vin plate in his toolbox until he gave it to me at the Petersen Museum in 2016. I had already completed my car as a tribute to the BRE team and John Morton when Dan sold me all of the surviving pieces. I then ripped the entire car apart and installing every little piece I could that had integrity and that’s when Rob Fuller stepped in to finish the car build like it was back in the day.”

Pictures from the race prep of Randy’s Z at Z Car Garage:

 
 

A sampling of the original parts is shown below including the exhaust header with megaphones, SW gauges, and BRE remote oil filter/cooler. Original BRE heat shield and fuel block pictured above.  All assembled by the crew at ZCG prior to testing:

   
 
 

Randy’s fanatic attention to detail and our team’s prep culminated in John Morton enjoying the Z at several race events:

“So many of the remaining pieces along with the 1971 championship motor is on display at my shop. After going to a few shows with John Morton in the car I told him I wanted to race it and he kind of smirked and said it’s a show car not a race car and my reply was we’re gonna race it will you drive it and he Sylvia was nonchalant and said yeah maybe… when we signed up and got into the first Rolex reunion in 2017 Rolex Monterey Motorsports Reunion.”

 

“John wasn’t really excited about racing the car Rob and I could see that even when he got belted in the car. When he came back after 6 to 8 laps a different man had returned he immediately walked over to Sylvia and said what are my times – He knew he was turning really fast laps and was getting really fired up! He told Brock down at the Carmel car show that the show car was truly a fast racecar! That weekend he terrorized all kinds of Porsches including 935s and was running up front in the top 10 out of a group of 40 to 50 cars. This became really fun so we’ve done it now at Road Atlanta Laguna Seca and now Daytona!”

 

Big thanks to Randy Jaffe, Sylvia and John Morton, the ZCG team Josh and Keith Corwin, Meghan Fuller, Michael Eberhardt and Vintage Racing Company and HSR this was a memorable event we can’t wait to come back to next year. More pictures in the gallery below:

LONG LIVE THE Z!

TUNING: Keith’s Datsun 510

Filed under: 510,Featured Cars and Projects,Performance
by Alvin G @ 8:13 pm on June 5, 2019

 

Keith Y came to Z Car Garage for dyno tuning on his Datsun 510 “Brock Buster” tribute. This Dime was a complete build performed by our friend, fellow racer and Datsun guru Troy Ermish.

 

Troy’s restoration of this car was fantastic and we love the 13″ Libra-style VTO with white-letters-out tires:

 

Underhood lies a Rebello 1700cc L-series with dual-Mikuni carbs and the chassis treated to a host of Troy’s suspension goodies:

 

When Keith brought the car to us it was not running correctly. Baseline numbers were 94hp/106tq. With Rob’s tuning the L-series now screams past 7ooorpm, making 125hp/114tq to the wheels. Gains of 31hp/8tq!

 

Enjoy the L-series music on the dyno, we included both engine and exhaust points of view:

 

Keith is happy and we are impressed (as always) with another Ermish creation. Coincidentally, the original real-deal Brock Buster 510 is being restored back it former glory as we speak at Troy’s shop! Looking forward to seeing it on the road.

DO IT IN A DATSUN!





 

We are extremely happy for our friend and fellow Datsun enthusiast Tom D and his newly acquired B-sedan Datsun 510. This is a historically significant race car built and run originally by Norm Balzer.  Here it is at Road Atlanta in 1977:

 

Tom brought the 510 to Z Car Garage to have it prepared for the upcoming race season:

“I bought the car rough three years ago from Steve Link with the help of Dave Stone. Since then I exchanged information with MaryLee Balzer (the original builder and owner’s widow) and Jon Koobation, the last guy to campaign the car. Both kept all the records and materials associated with the car.  They graciously gave me all of it, even Norm’s race jacket (so cool). My plans are (with Rob and ZCG support) to get the car track ready.  The car will be campaigned with its original livery and as much of the original equipment as possible, including the FIA prepped L18.”

 

 

The car was wildly successful on the West Coast.  Many, including Larry Oka referred to the car as the “other BRE car” since it was built with the help of Mac Tilton and hardware from the BRE garage as the Trans Am series ramped down.  Tom plans to run several events this year including CSRG April at Infineon Raceway, The HSMA Festival of Speed in Late May,  The Rolex in August and the CSRG Charity Event in October. We are currently breaking the car down for race prep. It is shockingly original and a treat to see!

 

 

Enjoy that twin-Mikuni carb’d L-series sing!

A Rich Racing History

Purchased from a local Datsun dealer in 1971 for a one dollar, Norm Balzer took this Datsun 510 which was damaged in shipping straight to the garage to create one of the most successful B Sedan race cars on the West Coast.  With help from Mac Tilton, many parts were sourced from the BRE garage.  Norm raced the car from in B Sedan from 1973 until 1979 and then later as a GT2 entry in 1980.

Willow Springs 1976 and RA in 1979:

 
 

Jon competed with the 510 in GT2, GT3 and IMSA/GTU Special Group 2 from 1981 to 1992, amassing a number of first place finishes including a win in IMSA SP2 at Laguna Seca in May of 1983. Together Norm and Jon took this Datsun 510 to the podium forty times with thirteen first place finishes and six Southern Pacific Division Championships. Overall they competed in eighty-six races between 1973 and 1992.

 

 

Stay tuned for an in-depth look at this historical Datsun race car!
