Dave L comes from Carmel Valley and he visited Z Car Garage for suspension upgrades on his 1972 Datsun 240z. Prior to meeting us he added many parts to the car himself like a 5-speed transmission but needed our expertise for Z-specific parts. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with a dyno-tuned 2.8L L-series really transformed this pretty S30.

  

Suspension

 

The chassis was treated to a full suspension rebuild with new parts and bushings from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

Stock vs T3 T/C rods up front:

 

Stock rear lower control arms were replaced with T3 adjustable units:

 

Dave provided us with a set of Tokico/springs from back in the day. We installed new tie-rods, Nissan ball joints, rack bushings, bump stops and moustache bar bushings:

   

 

ZCG Big-Brakes and CV Axles

 

Our readers are likely familiar with “Mrs. Butters”, our 1971 Series 1 240z shop demo car with full suspension and our ZCG Big-Brakes. Following a test drive in Butters, clients are sold on our Z Car Garage Big-Brakes and Z Car Garage CV Axles! Read below for a brief description of these parts:

     

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Do you remember your first car? For Kevin M, his first car was a 1967 Bluebird RL411 that he purchased as a teenager. For his 50th birthday he bought a Bluebird just like the one he had in high school and came to us for mechanical help.

 

Kevin is a long time Z Car Garage customer with his pretty Cherry Red Pearl Slicktop Z32 300ZX, so we happily obliged to take on the 411 project. We knew that it would be a challenge as his 411 was the very rare, “SSS” model. Not familiar with the 411? It is a hybrid of sorts with a body designed by the Italians and mechanics built in Japan by Datsun.

 

The Bluebird had a 1300 cc engine and its body was designed by Italian coachbuilder Pininfarina. The SSS was a high performance sedan version of the Bluebird that used a slightly modified version of the engine from our beloved Datsun Fairlady 1600 sports car. Let’s take a look at Kevin’s history with the 411…

Bluebird Beginnings

 

In 1978 at the age of 16, Kevin’s first car purchase was this 1967 Datsun Bluebird 411 sedan. He had many fond memories in it as a teen:

“I drove the car all through my time as a student at Cupertino High School and at De Anza College. The 1980s! It was kind of a funny looking car, but I just adored it. I drove it to my high school Junior Prom, as you can see from the photos. My brother and I once even drove all the way from Bay Area up to Sweet Home, Oregon to visit our mom. A bit gutless going over the big grades, but we made it there and back without many issues. 

I drove this car all over the Silicon Valley, to school, to work, Santa Clara Vanguard rehearsal, ‘Tino football games, to midnight movies, to KOME where I volunteered, to KFJC, my college radio home, to the beach in Santa Cruz via the Old Santa Cruz Highway, and especially up and down Highway 9.

 

Birthday Bluebird

 

At some point while going to college, the head gasket blew and Kevin decided to sell the car. He regretted selling it, considering all the memories the 411 gave him. On his 50th birthday Kevin remembered the soft spot he had for his Bluebird and purchased one in 2013 from noted 411 expert Tom Neely:

“I was so excited to have this car in my hands. It was very nostalgic driving the car once again. The sounds, the smell, the look and feel were all too familiar. The difference is that this was the RL411 SSS, a more powerful version of the Bluebird I once new. I drove it all around the San Francisco neighborhood where I live, picking up loads of smiles and thumbs up.”

 

Getting The SSS Back On The Road

 

Kevin was able to enjoy his “new” Bluebird until the engine made a horrible noise. He visited Z Car Garage in 2014 and we diagnosed the R16 with a rod knock. Kevin and Rob discussed a restoration with premium replacement and NOS parts at the heart of the build. We knew that finding parts for a car like this would be very difficult and accepted the challenge. Early stages of the build included a hot-rod R16 engine from Rebello, refurbished brakes/hydraulics, upgraded ignition and gaskets.

  

Unicorn Parts

The original exhaust manifold crumbled to dust once removed so another one was sourced and replaced.  The custom exhaust system built by Neely gets great reviews from other RL411 owners. Note the downpipe is routed through the fender:

 

“Rob Fuller and Z Car Garage’s vast network had somehow found one last RL411 water pump! The unicorn! I could not believe the news. The part was installed, and I received the car shortly thereafter.”

The engine was treated to new upper/lower radiator hoses and a new Nissan gasket set:

 

Chassis

With the hot-rod parts being installed into a chassis from the 60’s, everything needed to be gone through to make it road worthy. The braking system was overhauled with new calipers, F/R wheel bearings and new rear wheel cylinders. We also rebuilt the suspension:

   

What vintage Datsun would be complete without a set of Panasports?! We couldn’t resist fitting some 14×6 Panasports with Star Spec tires. Lowering blocks in rear make it look sharp! More pictures in the gallery below:

 

Interior

 

We really dig the interior on the 411s as they have a very classy look and feel. The dash was worked on with attention to the gauge cluster and trim. The heater core was removed/rebuilt and the control valve pressure tested to ensure the heater/defrost was functional:

 

New seats sourced from another 411 with a matching rear bench and new carpeting were installed:

 

 

Details

We convinced Kevin to breathe some life into the old paint with a cut and buff…the results were impressive.  The car was undercoated and detail painted, here is a before/after:

 

 

While buying some parts for Meghan’s 312 Bluebird we got a set of NOS 411 bumpers and hooked Kevin up.

 

Tuning

We replaced all the fluids, installed an upgraded East Coast Datsun distributor (Thanks Tom!), upgraded alternator and brand new set of factory plug wires. Rob dyno tuned the R16 with Z Therapy SU carbs making 79hp/95tq at the wheels:

 

Kevin took delivery of his refreshed 411 and he was stoked:

“I headed down to Z Car Garage. Rob handed me the keys and said, ‘take it around the block. Tell me what you think.’ I did so. The car was like another beast. The engine roared to life. It seemed was fresher and angrier. That extended out to the test drive. What performance! The Bluebird was was back! More performance than before and zero backfiring. I could really wind out the R16! “Well?’ asked Rob. ‘Amazing!’ I exclaimed.” 

 

 

Enjoying The Ride

Kevin was so excited that his Bluebird was fresh and ready he made the long journey to attend the 2018 Japanese Classic Car Show. There, he was recognized for his long drive in the Bluebird from San Francisco to Long Beach:

“I received an “Iron Butt” award for distance traveled to the show. Even more importantly, the Bluebird made the trip home, as well. Since JCCS, I’ve shown the car locally at the ZONC show and got a lot of interest in the car. Again, it’s so odd that even Datsun enthusiasts had never seen one before. It can’t really win car shows, as there is no category for these oddball 411s!”

Indeed, we were stoked to see Kevin and Bluebird at the ZONC Annual Classic Car Show:

 

He joined us on a local Holiday Fun Run through the Santa Cruz Mtns:

 

He even attended the Route 66 Classic Car Show in Williams, AZ where he joined a few other 411 owners, again driving all the way there and back!

The Bluebird is being daily driven in San Francisco:

 

We enjoyed the journey to bring Kevin’s RL411 back to life and it makes us happy to see him Enjoying The Ride:

“I thank the Datsun gods for putting this project into Z Car Garage’s hands because they came through for me in the end. I don’t believe I would be driving the car if it weren’t for their knowledge and persistence. Here’s how the car looked after I picked it up from Z Car Garage.”

 

Big thanks to Kevin for sticking with us through the build and everyone in the Datsun community that lent a hand like Mike Young. Datsuns Are Driven!

 We enjoy helping Z cars owners get their cars in top shape to Enjoy The Ride. David P purchased this 1975 Datsun 280z on the East Coast and the exotic shop it was at had difficulty with it. David moves between San Francisco and Massachusetts and wanted us to sort his Z out before hitting the roads here. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with tuning and aesthetic upgrades transform this Z.

 

Affectionately called “Triple Six”, the Z arrived at our shop from the East Coast via Masney Auto Transport (Thanks David). David had not seen the Z in person yet since purchasing and it needed some attention, Z Car Garage style.

 

The car was not running upon arrival and Rob had many suggestions after the initial assessment. From David:

“When Rob called to tell me that my car had made it there I said ‘Ok great. Can I tell you what I want done?’ to which Rob replied ‘Nope’. He said ‘I want you to come down here, drive my car and then say to me, OK I want you to do to my car whatever it was that you did to yours’, and after driving his car I did say those exact words.”

ZCG Big-Brakes and CV Axles

 

Indeed, we had David test drive “Mrs. Butters”, our 1971 Series 1 240z shop demo car with full suspension and our ZCG Big-Brakes:

“I drove Rob’s unassuming, Safari Gold 240Z, that he appropriately named Butters, and God damn was it fun! I was surprised when he told me it had 275 horsepower, not a small number for a car that’s so small and light, its just that it felt much more powerful than I ever thought a sub 300 hp car could feel.”

 
After the test drive he was sold on our Z Car Garage Big-Brakes and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

At Z Car Garage we have been maintaining and modifying late model Nissan/Infiniti sports cars since 2004. From Z cars (Z32, 350z, 370z) and R35 GT-Rs to G35, G37, Q50/Q60 cars we look forward to working on your vehicle. Efrain S visited us from Sacramento with his 2019 Infiniti Q60S Silver Sport for basic performance upgrades from AMS Performance including their AMS Heat Exchanger and AMS Air intakes and a Z1 Motorsports Blow-off Valve kit:

Dyno Tuning

 

Straight from the factory, the VR30DDTT is an impressive motor. The Hi-Output version is rated at 400 hp and 350 ft-lbs tq, underrated as we have seen with dyno testing. With a few bolt-ons and tuning, even more power can be unlocked from the VR30. Rob dyno tuned the Q using EcuTek. Baseline power was 333hp/314tq at the wheels. With the AMS parts and tuning final numbers were 412hp/452tq, gains of +79hp/138tq:

 

The VR30-series responds so well to bolt-ons and gets us excited. It’s almost like Nissan has comeback full-circle as the VR reminds us of modifying Z32TT’s in the 90’s:  big gains with just few upgrades. The Q-series cars are really well-suited to the upgrades too with a very comfortable ride and massive hp/tq when you want it.

Here is the Q on the dyno:

 

Efrain was very pleased with the power gains:

 “Honestly man my experience with Rob from start to finish was amazing. I could tell he loves his job, loves what he does and energy was on 100%, 7 days a week. Once I got the results back from the tune I was blown away I thought I was maybe going to see about 400 horsepower to the wheels at the most and he got it over to 412 with 450 torque, I couldn’t believe it. My bolt-ons are flawless, could not be anymore happy with the work from you guys and the whole experience I love the car thank you guys.”

Enjoy The Boost Efrain!

Last week we had the pleasure of dyno tuning Eric Straw’s magnificent 1969 Datsun 2000 Roadster. Eric is a long time friend of Z Car Garage and we  first dyno’d this roadster in 2012 while a few years later we enjoyed tuning his RB26DETT powered DR30 Skyline. In addition to being a talented fabricator it is clear that Eric has a penchant for white paint, red valve covers…and turbocharged Nissan powerplants!

 

SR20 Roadster: Version 2

 

After restoring his roadster with an S13 SR20DET drivetrain a decade ago, Eric started working on the next evolution with a totally revised chassis and new engine (the previous setup sold for a customer’s roadster).  The new drivetrain consists of an S14 block (JE pistons, K1 rods, P12 oil pump) with a P11 VVL head (Kelford turbo cams, Tomei cam gears, Taarks VVL relocation kit, R35 coil packs) all mounted to the roadster frame using a Spriso Motorsports HD motor mount kit.

 

Providing boost is a GTX3071r turbo with Tial exhaust housing mounted to a Straw-fab’d custom tubular manifold with CNC 1 piece collector. On the cold side is a custom intercooler with Garrett core and custom intake manifold. It’s both pretty and functional considering the roadster’s tiny engine bay:

 

Backing the SR20VE-T is a 6-speed (CD009) transmission normally seen in the Nissan 350z. The SR mounts to the tranny via a Mazworx bell housing with an OS Giken Twin disk. The shining star in Eric’s craftsmanship is the chassis preparation with a heavily modified frame with tubular x-member and bolt-in reinforcements.

 

It would take another blog post to dive into the suspension but if you are curious about the restoration and more please check out Eric’s roadster featured in this Speedhunters article by Naveed Yousufzai HERE.

  

Dyno Tuning

 

The tuning session was conducted with driveability and longevity in mind. Outright peak power numbers were not a priority. Eric’s hometown in Salem, Oregon is where this car would be enjoyed with premium fuel and the occasional 100 octane splash.  Surely more power could be extracted with E85 but Eric is 50 miles from nearest station. Rob comments on the choice of engine management for the SR20VE-T:

“When Eric contacted us about about building the SR20VVL we discussed EMS, and ZCG is a Haltech Pro Tuner. We really like how user-friendly this product is for a tuner. It’s perfect when you need to map out all of the different phases, complete control of ignition/fueling, cam control, idle air…everything to take this car you’ve dreamed of and make it drive like it came from an OEM factory.”

 

Rob dyno tuned the SR equipped with a Haltech 1500 Elite. Initial passes were performed on 92 octane. The plots below show without a boost controller (387hp/287tq) and with a boost controller, making 425hp/331tq to the wheels:

 

Of note is Nissan’s wonderful variable valve timing (VVL) at work with a very flat torque curve and incredible, spine-tingling cam changeover sound. See video below! Eric and Josh drained the fuel tank to add 100 octane for the next passes.  Fueling is supplied by a custom stainless tank (Aeromotive hangler/bladder), custom stainless lines all dash 6, 1300x Injector dynamics and a Radium Fuel rail:

 

On 100 octane the SR20VE-T made 491hp/393tq at the wheels. That is roughly 570hp at the crank. Keep in mind this little Datsun roadster weighs 2250lbs with a hardtop and 14 gallons of fuel!

 

Driving Impressions

 

Following the dyno session we had to take the roadster out for a drive. This video shows multiple dyno passes and test drives, volume up!

 

 

Here are a few driving impressions from the three of us, enjoy!

Eric

“The car went from being an impressive car to completely coming alive and becoming a rocket ship that just keeps pulling. The VVL is like another level of performance. The power comes on very progressive and linear to give the chassis the best chance of getting as much as possible out of it. We made multiple setting to help with driving goals based on the roads and situations we are in.”

 

“The suspension has been a lot of work and has really paid off many times over be able to get this power to the ground and drive the car like it was intended. The rear suspension is so predictable and precise that immediately I had a lot of confidence to be able roll some power out of the corner. Rob had truly made this dream come alive and make this car so very impressive.”

 

Rob

 

“The cam control and air flow from the VVL is staggering, just really super cool. I’m not surprised…from being around the DR30 and seeing all the cars Eric and Michael Spreadbury have built over the years.  This roadster continues to evolve as they continue their craft with each chapter revealing a new level like a boost controller: 5 years ago was 10lbs of boost, 2 years ago 12lbs,  and now 22lbs (this roadster should only be driven on high!) Eric Straw isn’t just one man. He seems to be a mass of people to not only design an engine bay and make it work efficiently but also bolt a non-matching transmission, and then that rear end suspension….obviously one of the biggest things when modifying a 50+yr old Datsun with high power levels is trying to put it down. His engineering accounted for enough tire, brake and balance. The setup Eric built for this roadster I could not believe how we could deliver 500+hp/almost 400ftlbs of torque, and yes we were lighting off the tires but…I still felt like I was in control. We were on ice, but I felt like I was on Speedvision from back in the day of World-rallying Championship..with just a slight motion of the steering wheel I could rotate that car wherever I wanted. 

 

Alvin

 

“As a passenger and long-time roadster owner…it’s not easy for me to ride shotgun in a high-powered car but I still can’t fathom how smooth it felt under intense acceleration. These are super tiny cars and to see both Eric and Rob harness it was a testament to Eric’s chassis engineering. I’ve been in other Datsuns with turbo SRs and they will pitch sideways under full throttle but this one was planted even on our rough downtown roads. Watch the video. It’s epic.”

 

All of us concluded and shared similar sentiments: Eric’s suspension enabled this roadster to manage all that power. When boost hits and the tires break loose it can be seemingly glide controllably with steering input…no hopping or skittering. The rear suspension consists of a hybrid rear axle built by Moser based on a Dana 44 with a Torque arm and 3-Link Watts with Ridetech coil-overs. Up front are custom Ridetech coil-overs and sway bar.  R33 GTR Brembo brakes provide stopping power. The Watanabe wheels are wrapped in 225F/245(!)R tires which are massive for a stock-flared roadster body.

 

We had blast spending the day with Eric and tuning his roadster. We can’t praise him enough for the ingenuity and execution of his build. Eric would like to thank Julie Straw, Michael Spreadbury and Rob Fuller.  More pictures in the gallery below and Enjoy The Boost Eric!
