TUNING: Geoff’s 1972 BMW 2002

Z Car Garage specializes in dyno tuning of vintage cars and this includes non-Nissan/Datsun classics. From establishing a baseline on street cars to preparing race cars for high-profile events we love helping each client achieve the best performance possible. Geoff W’s 1972 BMW 2002 came to Z Car Garage for a dyno tuning session with fantastic results.

 

Geoff is a friend of the shop with a great story behind his love for all things engineering and automotive. Let’s hear how he got into cars and acquired the BMW 2002…

Generations of Car Enthusiasts

 

“My father owned Formula Fords growing up and has owned a Lotus Elan since 1977; we spent a lot of time in the garage together in my formative years. I was exposed at a young age to AutoX and vintage racing I distinctly remember falling in love with Lotus Sevens and B-sedan cars. When I was of driving age, I purchased a 1985 Mk1 Toyota Mr2 (Chassis code AW11) and began to do a lot of track days and AutoX. This eventually led to another 4age powered car: The Toyota Corolla GTS (Chassis code AE86). I was going to college in southern California at the time and was involved with Club4ag.com which started holding drift day events. This was before professional organizations such as Formula D came about.”

 

“As a poor college kid, I started working drift events and track days in exchange for track time. I eventually became an instructor and won one of the earliest US drifting competitions in my largely-stock, daily-driver Corolla. After school, I bought a Caterham 7 Super Sprint, and while it was fun, it was never quite the original Lotus Seven I pined for. I eventually sold all of my “fun cars” to fund a house purchase in San Jose. After a few years, I finally acquired my Lotus Seven in 2013 as a tired vintage race car from Texas. I built a road-going motor and installed a synchromesh transmission for the car and finally got it running a year later.”

 

“I’ve been enjoying driving and developing it in the years since. Alvin from Z Car Garage and I met a few years after this car was finished and we became fast friends. Some of my best memories with this car have been spent driving in the mountains surrounding San Jose with Alvin. I’ve done a few vintage car rallies and been on track with it, but I eventually would like to do some vintage racing.” (See Geoff’s Lotus 7 in this excellent Petrolicious feature HERE)

 

The Inka Orange 1972 BMW 2002

“In 2018, I sought out a B-sedan road car to take on vintage car rallies and have something fun to drive in inclement weather. Alfa GTV’s, Datsun 510’s were out of my price range and I couldn’t find any Mk1 Ford Escorts/Cortinas for sale. I began looking at BMW 2002’s; I especially liked them in bright/interesting colors popular in the early 70’s.”


“When I bought this car, the previous owner didn’t know much about the engine. It had a pair of Weber 40dcoe’s, ran well, and seemed to feel like other stock bmw 2002s I had driven. I haven’t made many changes to the car, but did locate and install a set of rare and period correct Campagnolo wheels. Earlier this year, I found and purchased a Mk1 Cortina and I was going to sell the BMW 2002 because it wasn’t as exciting to drive.”

 

Dyno Tuning

 

The 2002 baselined at 99hp/114tq and after tuning put down 129hp/127tq at the wheels! Let’s hear from Rob…

ROB: “Being around so many B-Sedan race cars I wanted to see what all the hype was surrounding the BMW 2002. I started talking with Geoff about trading one of my S30 Z cars for his BMW. He kindly lent it to me, and I drove it to the Monterey Historics to root on our friend Jim Huff in his Neu Klasse BMW. First impressions were that it was anemic and the dyno confirmed this. Full-throttle was compromised so it needed throttle-linkage adjustment plus timing and jetting. It really came alive making great power…

 

Enjoy the video below to see Geoff’s BMW on the dyno, test driving with Rob and enjoying a few road rallies:

Hold on to that 2002!

 

Rob and Geoff recall how they felt about the 2002 post dyno tuning and test driving:

ROB: “With +30hp/13tq this BMW was born again, and man did I like the German 510. Love the visibility, greenhouse, seats, thud of the door closing. Despite being a die-hard Datsun 510 guy I really dug the 2002. Enjoyed it so much that I thought maybe this was going to be my first German car. I drove it, Meghan drove it, and just as I was getting excited, (un)fortunately Geoff finally drove it…our improvements to the car convinced him to keep the 2002.”

 

GEOFF: I hadn’t even considered having it tuned, but Rob suggested giving it a try. When I drove the car after Z Car Garage worked their magic, I was absolutely floored. It is a completely different car now, gaining 30 horsepower and this was not the “stock” 2002 I had assumed it to be. I’m absolutely kicking myself I didn’t have it tuned by Rob earlier. Needless to say, I am no longer interested in selling it. I feel like I’m experiencing a whole new car I cannot thank Z Car Garage enough!”

On Datsuns:

 

We introduced Geoff to the magic of the Datsun S30 Z car after joining him on local mountain drives and rallies. He gets it…

GEOFF: “Being around the shop, I have an even stronger strong appreciation for both 510’s and Z cars. I was recently given the opportunity to drive Mrs. Butters and was completely blown away by the Z Car Garage Big Brakes. I have never felt brakes like that on a vintage car; they’re more impressive than most modern cars! The sound of that L-series on triple Mikuni’s is absolutely intoxicating. While I’ve always preferred smaller/lighter 4 cylinder cars, a S30 tuned like Mrs. Butters is definitely on my short-list of next cars to own. It also helps to have a reputable shop so familiar with these cars in the area!”

 

Friendship

ALVIN: “It really is a small word. Geoff and I both work at the same company and didn’t meet until we saw our beloved vintage cars featured in Petrolicious. Since then we’ve enjoyed Bay Area backroads and beyond. Good times from running rallies with Driving While Awesome, to attending race events and weekend blasts. Geoff is truly someone I’d wish I had known earlier in life. Here’s to more memories and drives.”

 

Just a few events we have enjoyed with Geoff over the years, with more photos in the gallery below:

EVENTS: Cars and Coffee with Driving While Awesome!

EVENTS: Super Drive Sunday

EVENTS: DWA Rally From Home South

 

ROB: “Happy to help Geoff sort out his BMW. He’s such a great car enthusiast and friend to the shop, myself and Alvin. Wonderful 2002. B-Sedans are not just Datsun 510s, they are in the form of BMWs, Alfas and other marques!”

RACING: Datsun Heroics at The 2018 Mitty!

Filed under: Events,Featured Cars and Projects,Performance
by Alvin G @ 12:33 am on May 11, 2018

 

Each year the Historic Sportscar Racing association (HSR) organizes the largest and oldest event for Historic race cars on the East Coast. It’s called the Classic Motorsports Mitty and it took place at Road Atlanta, GA from April 27-29. We attended The Mitty to provide race support for Randy Jaffe’s #46 BRE Datsun 240z (driven by our hero John Morton) and Alex McDowell’s Datsun Bluebird Coupe and Hakosuka Skyline.

 

Nissan was the featured marque for the first time with John Morton serving as Grand Marshall so naturally every Datsun-fan was drawn to The Mitty. I took a Thursday night red-eye flight from San Jose with part of the ZCG crew and when we arrived at Road Atlanta our paddock was an absolute feast for the senses. Nestled primely across from the front-straight footbridge, we had an impressive display of West-Coast racers, from L to R: The BRE Datsun 240z, BRE 370z, Comedian Adam Carolla’s #44 Frank Monise Datsun 2000 Roadster and Bob Sharp 610, Alex’s Hakosuka Skyline and Bluebird Coupe, the Friselle GTU 240z, Dave Stone’s Frellsen B-sedan 510, Jim Froula’s (Racecraft) Datsun 260z, our friend Glenn Chiou’s VIPS/Loren St. Lawrence 240z and Bob Clucas’ IMSA GTU 240Z.

 

Take a Lap With John Morton

 

At 76 years of age John Morton is still formidable behind the wheel. Here he is piloting the #46 BRE 240z that we prepared around Road Atlanta; the very same track where he won the 1970 and 1971 National C-Production Championships!

 

Well, That’s Racing

The sweet smell of race fuel, frantic adjustments, checklists, and engines blaring to warm-up for the next session all reminded us how much we love racing!  From the on-board video above, you can see the BRE 240z performed well with John Morton at the wheel but what it does not show viewers is the not-so-glamourous side of racing: part failures. The Z ran great in Thursday’s practice but when we arrived at the track Friday morning, Rob told us the engine failed during the first session. He needed all hands on deck. What followed absolutely humbled me; the ZCG crew went to work in a supreme effort to get the #46 BRE 240z alive again for Saturday/Sunday’s races.

 

John Morton Must Race

To get a first-hand perspective of the Z’s revival I asked ZCG Lead Technician, Josh Corwin, to give us the play-by-play of the heart transplant. Please read on to see a video chronicling the events!

1) How, when and why did the engine fail?
It is still too early to know exactly what went wrong with the engine. A complete teardown will be performed to isolate the root cause. I can tell you that during Friday practice, John Morton was accelerating up Road Atlanta’s back straight coming up the hill before turn 10, in top gear at wide open throttle well over 100mph. That is when a major engine component let go resulting in multiple holes being punched through the engine block, affectively turning the engine into a boat anchor.

2) What was the plan to get John Morton back on the track?
Get an engine, put it in the car, put John Morton in the car, and put the car on track. Simple enough, except finding an engine that could perform was the challenge.

As word spread through the paddock that John Morton needed an engine, the Datsun Community banded together, and offers of engines came swarming in.  Multiple race engines and high performance street engines were all up for grabs. All were seriously built engines, but none of them felt right.

Rob’s ultimate plan to excavate a couple E.B. Parkinson motors, like dinosaur fossils, was crazy to say the least. But, going with his gut, the resurrection of a true vintage race engine was put in motion. Half of the crew went with Randy to his storage to look for a replacement motor, while other half, including myself, received the green light from Rob to began the task of removing the expired power plant in anticipation of the Datsun Relics arrival.

3) Technically, what was involved with swapping parts and prepping the 40-yr old parkinson motor?

The old engine came out quickly, as many hands made light work.  It was then tucked away into the back of the trailer, to be disassembled at a later date, as we worked on getting the car ready for its new engine.  Prepping the vehicle was pretty simple, but there were necessary steps and precautions that need to happen to make this a successful transplant.  We only had one shot at this, so nothing was left to chance.

Below, (L): Gary Brizendine and BRE Engine Chief John Caldwell lend a hand and knowledge: Caldwell is confirming the jetting on the 50mm Mikuni carbs.  (R) The original exhaust system from the 1970s is removed from #46. Morton had already blown apart the exhaust tips on the first session!

 
 

With any catastrophic engine failure, one of the concerns is metal bits getting stuck in the oil cooler and lines. So, first thing is to remove the oil cooler and hoses and flush them out.  Any leftover engine material in the oiling system can destroy a fresh engine in minutes. Luckily, Road Atlanta’s used oil disposal shed also had 2 solvent tanks, which we used to back flush the cooler and clean the lines of any possible debris. While all the reusable pieces were getting cleaned internally, we moved on to cleaning the mess of shrapnel and engine oil that coated the engine bay.  Just as we finished, the oil cooler system came back fresh and clean, and shortly after engines arrived.  We could finally switch gears to the reassembly of the BRE 240Z.

 
 

The crew brought back two “long block” engines, meaning the cylinder head and engine block had already been assembled. At first look they were identical in every way and definitely appeared to have been sitting for 40 years. Looking closer, we found one of the engines did not have the timing chain installed which led us to use the one that was “more complete.” We put a wrench on the crank bolt and it rotated 720 degrees, smooth as butter. The next task was to take all the undesirable accessories from the old engine. The 40 year old water pump, alternator, flywheel, crank pulley, thermostat housing, oil filter adaptor, and valve cover were all tossed.  We then tackled a quick clean up, removing years of dirt and grim that had built up while sitting.

EVENTS: The 2016 SEMA Show!

What Happens in SEMA . . .

2016 marks the 50th Anniversary of the Specialty Equipment Market Association (SEMA) Show.  Every year, people from around the world arrive in Las Vegas to look at the astonishing display of automotive tuning and customization.

 

img_4020 img_3726
img_3871

Within the 1 million+ square foot, 4-building Las Vegas Convention center there are hundreds of lowered imports, resto-modded muscle cars and those crazy lifted trucks.  There’s far more to the show than that including celebrities, extreme demos, parties and general excess.  Unfortunately, SEMA isn’t open to the public, but that doesn’t mean you can’t experience what it’s like to attend the craziest show on the automotive calendar. Enjoy the following highlights from our visit to SEMA in Novemeber. We will start with our display car, the OEMs, Datsuns and move on to the wild stuff!

 

The OS Giken TC24B1Z Skyline

img_3312
 

Last year at SEMA we debuted the legendary OS Giken TC24B1Z engine inside our ZCG-restored Datsun 240z:

Nissan-Datsun-240Z-OS-Giken-S30-02-640x427 SEMA-2015-36-copy-800x533
 

The Z was well-received but very subtle (by SEMA standards) so this year we stepped out of our comfort zone and helped build a “flashier” vehicle for display…a 1971 Nissan “Hakosuka” Skyline!

img_3355 img_3354 img_3351
 

This time the TC24 was treated to different induction: Jenvey individual throttle bodies and EFI. Aesthetics were livened up with a red valve cover and white coated exhaust headers. The entire car was wrapped in a metallic red replete with sponsor graphics and 17″ Volk TE37V wheels on Nitto tires. Our “show hood” mod was utilized again to highlight the glorious TC24.

We were flattered by all of the fan pictures and even received a miniature scale replica of the Hako from Shingo!

 sema_2016_dino_dalle_carbonare_55 img_4859
 

The Hako garnered attention from many social media outlets and drew significantly more traffic than last year’s display. Later in November it went on to be displayed at the Los Angeles Auto Show!

Huge thanks to the crew from OS Giken and Alex M. Stay tuned we will have a full feature on the build soon!

The Big Manufacturers at SEMA

As always, there’s a big presence from US manufacturers, but this year Honda and Toyota (among others) made an impact on the show floors. Here’s our round up of the big displays.

Ford

img_3870
 

Ford had the largest display in the main hall with an extensive showing of their hottest cars and trucks. My favorite was the new GT supercar complete with battle-scars from a LeMans race. It even sat across from an original Ford GT40. Ken Block’s “Gymkhana 9” Focus and other tricked-out Foci below:

Honda

Honda announced its return to the Pirelli World Challenge series in 2017 with this NSX GT3…being towed by Acura MDX!  Below, the new NSX looks great in white, the new Civic showed as body-in-white tuning platform and the new (for the US) Civic Type R:

Toyota

img_3764
 

Toyota had a neat throwback-style displaying paying tribute to its heritage vehicles. They even brought out the entire generation of Corollas in celebration of its 50th anniversary! Below: 1951 Land Cruiser, 80’s Van and the “World’s Fastest SUV”: a 2,000hp twin-turbo’d v8 Sequoia

Datsun Domination at SEMA!

We begin our coverage of all the Datsuns/Nissans at SEMA, and there were plenty! Let’s start with our OS Giken booth neighbor, ENEOS. Their display car was none other than Ginash George’s C10 Skyline. Ginash is the founder of the successful JDM Chicago and also owns a beautiful NSX.

img_3335
 

Ginash enlisted the expertise of JDM Legends to build this stunning Hako. All the right choices on this one! And he’s a wheel aficionado to boot as well. Super Street gave it a SEMA award!

img_3343 img_3346 img_3345
 

FOUR S30 Z cars were at SEMA. If we had to pick a favorite it was the ChasingJs 280z built by Dominic Le. You might be familiar with his last SEMA creation, the Hakotora that was featured on Jay Leno’s Garage.

 

img_3616
 

The build was based on a rendering from talented artist Jon Sibal…and built in Dom’s garage!

screen-shot-2016-12-03-at-1-22-00-am img_3942
 

The clever John Player Special striping was hand-applied by Dom himself. Note the rare G-Nose headlamp covers. Power comes from a single-turbo 2JZ-GTE with 1,000hp as the goal. We love it!

img_4232 img_3936 img_3935
 

The Liberty Walk Fairlady Z turned heads with its unmistakenable bosozoku style. Sporting their fender flare kit, “notchback” rear hatch, smoothed rear panel and small-ish 15″ wheels it seemed a bit out of place in the DUB nation booth, but still cool.

img_4058
img_4062 img_4060
 

Chris Forsberg’s 280z underwent a total makeover for SEMA.  The single turbo RB26 revieved a custom billet valve cover and the body showed off a new kit from Carbon Signal.  The kit really flows well with the G-nose and front spolier. The interior was also finished by Amir and his team in the UAE.

The legendary Pete Brock displayed his personal BRE Tribute 240z in the Braille booth:

A lone Datsun 510 slammed via AirLift suspension and 13B rotary power. The BBS wheels were mint!

img_4004 img_4011 img_4008
 

This Datsun Bluebird L320 pickup was a pleasant sight amongs the wild bodykits. You see those chunky rear tires on widened steelies? They’re probably necessary to reign in all the instant torque from the electric motor conversion!

Late Model Nissans

Steve Pham’s unorthodox turbocharged BMW N54 turbo. This Rocketbunny “Boss” kitted Nissan 240sx (S14) had new BRE-inspired livery for the show. Below, a JDM model S15 Silvia with a widebody kit:

Commuter Week continues at Z Car Garage. We take average transportation and make it exciting! Chris C hails from from San Francisco, CA. He commutes in his Infiniti FX35 that we performed several upgrades to last year:

ZCG 41315 080
 

Based on our service with the FX he asked us to step out of our comfort zone and take care of his fiancee’s Ford Edge. We happily obliged. With 84k mies on the coloc came in for a little refresh including new tires, springs, shocks, brake pads and address a few nagglish issues she’s had.

 

1916 cam 5 174
 

KYB shocks up front/rear with H&R lowering kit. The springs drop ride height by 1.75″/1.5″, respectively:

1916 cam 5 177 1916 cam 5 180 1916 cam 5 186

Stoptech brake pads front/rear but not our usual favorite “309” item. Instead we used the Stoptech “105” pad which is made for daily driver usage. Note the huge fender gap at stock ride height:

1916 cam 5 179 1916 cam 5 181 1916 cam 5 173
 

After the H&R lowering kit the Edge looks great, here is a before/after:
