TUNING: Erik’s 1970 Datsun Roadster

Filed under: Featured Cars and Projects,g35,Performance
by Alvin G @ 3:11 pm on August 29, 2022

 

Z Car Garage specializes in dyno tuning vintage cars. Our in-house dyno and expertise in carb tuning can help your engine reach its potential whether it is a street car or full race car. We love Datsun roadsters and recently dyno tuned Erik’s 1970 1600 with great results. Let’s take a look at how he got into Datsuns…

 

Roadster Beginnings

Affectionately named “Audrey”, Erik bought this 1970 Datsun Sports 1600 in 1995 and drove her every day while living in San Jose and Santa Monica, CA. He had lots of adventures in those days, including driving on Highway 1, Route 66, and even blowing a head gasket in the desert outside Needles, CA.

“In 1998 he got a job in Thailand and Audrey was put in storage. Stored outside for years, she suffered the indignity of being broken into and vandalized. (I’m still apologizing to her for that.)In 2000, I moved back to the USA, but had no garage for Audrey, so she remained outside, staying with friends and family. By 2003 she had finally moved inside, but a busy life and no shop space meant that she sat in the corner, patiently awaiting resurrection.”

“Fast forward to 2019: now having a great garage space and some free time, it was time to get Audrey back on the road. On the outside, she still wears most of what’s left of her original 52 year old paint, but inside and underneath it’s a different story: Her factory 96 horsepower has been doubled using the original engine, and her 4 speed transmission has been swapped for a 5 speed. The body was removed from the frame, all suspension, steering, and brakes were redone/upgraded, all electrical wiring replaced, every nut and bolt was either re-plated or replaced, and the interior restoration has begun, slowly changing from black to red.”

 

Erik and Z Car Garage

 

Erik heard about Z Car Garage through 311s.org, the definitive resource for all things Datsun Roadster. He purchased a G35 coupe and called Rob to talk about performance upgrades and the Infiniti was turned into a supercharged beast making 560whp.

“Since then, Rob has been super helpful while I’ve been restoring my 1970 Datsun 1600 from connecting me with the engine and transmission rebuilders, to helping with parts restoration, zinc plating, advice, and moral support. Once I had the car assembled and the new engine broken in, I knew I wanted to get it tuned on the ZCG dyno.”

Dyno Tuning

 

Erik’s roadster is a “1600” model, originally sporting 1.6L (R16) with dual-SU induction and 4-speed drivetrain. His restoration included stroking the original motor to a larger 2150cc displacement with twin-Mikuni induction and 5-speed (u20) transmission. You can learn more about Erik’s restoration efforts and the Rebello stroker R16 drivetrain all on 311s.org HERE.

 

Our initial dyno tuning session was with Phh40 Mikuni carbs. While it made great power Rob had always suggested running a larger Phh44 carbs to take advantage of the stout Rebello cam. Erik returned for another dyno session. With the carb switch, A/F ratio and timing optimized the roadster put down an impressive 157hp/151tq to the wheels with improved driveability throughout the entire rev range:

 
 

Erik was stoked with the tuning results:

“After finding some compatibility issues with my carburetors, Rob helped me build and install bigger carbs (the ones Rob had told me to use all along!). Came back for another tuning session and wow – what a difference. More power everywhere, better idle and driveability, and top end power is phenomenal. Many thanks to Rob and the whole Z Car Garage crew for taking my car from good to amazing!”

Enjoying The Ride

 

Datsuns Are Driven! In true roadster fashion, Erik has been Enjoying the Ride in his revived “Audrey”. We got the roadster prepped for a 600+ mile road trip to the Annual Datsun Roadster Meet at Mt. Shasta back in June. The car ran flawlessly:

 

Erik has been attending local car shows and rallys including VALT Car show in Berkeley, CA and Breakfast Club Rally.

 

We had fun tuning Erik’s roadster and getting it dialed in with the new drivetrain. Eventually it will be time for bodywork and paint, but he’s too busy having fun on the road! Thanks for letting us be a part of your Datsun journey Erik, you’ve done the roadster justice! If you have a vintage car (it doesn’t have to be a Datsun) feel free to contact the shop to schedule a dyno tuning session.

Rick’s 1965 Nissan Silvia

Filed under: Featured Cars and Projects,Maintenance,Performance
by Alvin G @ 6:41 pm on July 24, 2020

 
 

When we learned that a Nissan Silvia was in our area Z Car Garage got excited. This is not the 90’s Silvia (Nissan 240sx here) we know and love, it is the ultra-rare 1965 Silvia CSP311. Only 554 examples were made from ’67 -’67 and never imported to the US.

 

Fortunately for owner Rick K, he was able to acquire this Silvia from our friends at JDM Legends:

“My son (Matt) and I were searching for a nice 240Z. Throughout our search, Matt kept telling me about the Silvia (CSP311).  One became available through JDM Legends. I just wasn’t sure about it until we saw Myron Vernis’ beautiful Silvia featured in a recent JDM exhibit at the Peterson. When we saw the car in person, we were hooked. We purchased the Silvia from JDM-L. It is built on the Nissan/Datsun Roadster chassis and drive train, so it is fun to drive and reliable.”

The Luxurious Datsun 1600 Coupe

 

The Silvia is special for many reasons. As Rick mentioned above, this car was built on the Datsun Roadster chassis, meaning it is a body-on-frame platform sharing the same R16 drivetrain as the Datsun 1600 (SP311). All were hand built and right hand drive with a gorgeous interior. Fairlady owners will notice familiar gauges and switchgear–all borrowed from the contemporary Datsun Roadster. The body was designed by Kazuo Kimura with influence from Albrecht Goertz (of 240z/2000GT fame):

 

Although it was a beautiful, robust little coupe it was not a sales success for Nissan. It did however pave the way for the larger S30:

“Nissan shipped one to the fledgling Datsun distributor in the US. They did not think it would sell in the US (re-naming it a Datsun 1600 Coupe) and that was the end of CSP311. It never made it to full production. We believe ours is one of 5 currently in the US.  Most are in Japan with a large group in Australia as well.  We guesstimate that there may be 150 still in existence world wide.”

 

The Silvia at Z Car Garage

 

Rick brought the Silvia in to us for an inspection and to ensure it was road-worthy. We thank owner Eric Bizek of JDM Legends for referring Rick to us!

“Eric at JDM told us about Z Car Garage and Rob.  Knowing that one of the best shops in the country was 10 minutes from our house gave us the confidence we needed to buy the car.  We knew we had a great shop to work on it in the Bay Area.”

We developed a plan to address some deferred maintenance and sort out the tired suspension. A surprisingly clean underbody (remember this came from Japan!) revealed some corrosion:

 

To satisfy our curiosity we placed the Silvia on the scales and it checked in at a scant 2210lbs:

 

We even put it on the dyno to make sure the engine was healthy. Could this be the only Silvia in the US to be dyno tuned? 😀

 

The Silvia put down a stout 67hp/81tq to the wheels, enjoy the video:

 

 

Rick and son Mat have been enjoying the Silvia and sharing it with other enthusiasts.

 “Matt and I enjoy driving it often. We also have taken it to Cars and Coffee events in the Bay Area and most notably were welcomed with position A at the Wrigley building in Santa Cruz. The Driving While Awesome Cars and Coffee was one of the best we had been to.”

We also spotted it at the 2019 Saratoga Classic Car Show:

 

While Rick and Matt were at the shop we let them drive Butters, our  1970 Series 1 shop demo Z. They were hooked:

“Hi Rob,  It was great to meet you and your team.  Matthew could barely sleep last night after driving Butters.  Thanks so much for letting us take it out.  Truly amazing. We want a Z just like that.”

 

Big thanks to Rick for letting us work on the Silvia. We suggested that a car this rare and significant should be as close as possible to a factory correct restoration which we agree with. For now they are just Enjoying The Ride!





 

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:

 

One part, known as “the unicorn” part in the Datsun 411 community, is the RL411 variant of the water pump for the R16 engine. It is shorter and stubbier than the Fairlady Roadster version of the part. It is widely known that this part can no longer be found anywhere in the world. Kevin was happy we found one:
“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!
