TUNING: Pat’s 1970 Datsun 2000 Roadster

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 3:11 pm on April 4, 2022

 

Datsun Roadsters hold a special place in our heart and recently we had the opportunity to tune this very beautiful example owned by Pat S. The only reason we don’t work on or build these gems: we simply can’t keep up with our Z car workload. Once in a while though, someone will throw around the name “Alvin” (our shop social media manager) and they will get into Z Car Garage.

 

Pat contacted ZCG to discuss his 1970 Datsun 2000 roadster’s twin-Mikuni carb setup. The 2L/U20 models could be optioned with dual Mikuni-Solex carbs (replacing SU carbs) as part of a factory “competition” package also including a hotter “B” camshaft and 7.5qt. aluminum oil pan. Pat had done all he could to make it drive nicely and wanted a touch more driveability. Once at the shop, Rob took his car for a ride, impressed with how nicely restored it was.

 

Dyno Tuning

 

Rob and Pat discussed his goals and what he wanted to accomplish. We were able to go in and adjust the idle/off-idle settings, and of course wide-open throttle. The U20 put down 113hp/109tq to the wheels:

 

Pat was really pleased with the dyno tuning results. We actually saw him on the recent BCR Tokyo Calling Rally where he said the car was running fantastic and he was stoked:

“I saw Z Car Garage referenced on 311s.org when I was trying to sort out my carbs. I had the carbs completely rebuilt by Taka Sato at Kyusha House (beautiful job) and Z Car Garage did the fine tune adjustments on the dyno. Starts and runs great. So fun to drive! I once had a good friend that owned a high end Porsche shop (he races Lotus’ now) in LA. No matter who you were, if there was any oil or dirt on the engine, he would send them away. Rob reminds me of him. An expert with a true passion for the cars!”

Pat shared his Datsun story with us:

“I bought my first roadster in 1973 and it was a ’66 1600 that I paid $600 for. I’ve always wanted to get another so about 3 years ago I purchased my ’70 2L.  Mike Young of DatsunSports rebuilt the top end and installed a ‘B’ cam for me and has been a true friend by not letting make too many mistakes.

 

The car was striped down to bare metal, rusted panels welded in and a new paint job with rechromed the bumpers and trim.

 

Pat refurbished all of the electrical switches and lights (LEDs now). Gauge expert Jon Frampton refurbished the gauges. Pat also rebuilt the seats and has new upholstery throughout:

 

Enjoying The Ride

 

It was great to see Pat driving his roadster on the BCR Tokyo calling rally where he was all smiles with the tuning results. Here a few shots of him at speed in the foothills of Sonoma, CA.

 

Roadster owners united at the rally’s final stage at Sonoma Raceway (Alvin, Rob, Mike Young, Eric and Pat):

 

Pat you have done a great job on the roadster. Nice work, and we love seeing Datsun owners realize the maximum potential out of their cars. Thanks for your support and Enjoy The Ride!

We love working on cars and what really fuels the passion at Z Car Garage are the stories that connect each owner to their cherished rides. Christine K visited our shop earlier this year for routine maintenance on her 2004 Nissan 350Z 6MT Roadster and we were pleasantly surprised by her history linking to Datsun legends, mutual friends and family!

It’Z a Small Datsun World

 

Christine is a local San Jose school teacher and it truly is a small world as she was the kindergarten teacher for my two daughters just a few years ago. You can imagine how surprised I was to see her at Z Car Garage one day while I was there to work on zcarblog.com. At the time we were wearing masks and I did not greet her but later reached out via e-mail:

“Good morning, I am so happy you reached out to say something. I was so sure it was you, but I could not think of your first name in the moment and did not want to say “hi” Meena and Sophia’s dad. I inherited my Dad’s 350z when he passed away 3 years ago. I love that car and am so thankful we found the Z Car Garage. My dad worked at a Nissan/Datsun car dealership in my hometown in Corvallis, Oregon. He also ran the used car portion as well. I remember one of the first cars I got practice driving before I got my driver’s license was the Datsun 210 station wagon.”

 (Above) Leaving the wet and snowy northwest and bringing the Z home to their driveway in sunny California.

Not only was I excited to see Christine at the shop, her reply left me intrigued about that Nissan/Datsun dealership in Corvallis….could it be THE famous Scoville Nissan dealership? I reached out to our fellow Datsun-enthusiast and friend Michael Spreadbury who worked for famed race car driver Jack Scoville and inquired about Christine’s connection. Incredibly, Michael confirmed!

“Amazing — her dad would be Roy Robinson and he was a wonderful human being— we were friends indeed and it was quite the shock of when Roy passed away. Roy was a sales guy for Scoville’s for many years, but he retired before I started working for Jack— but Corvallis is a small town and Roy was in to see us at the dealership every week where I got to know him well. Roy always had Datsun/Nissan’s, and I always think of him with his spotless white Z32…After he retired he drove school busses, and took both of my kids on outings as the bus driver— whenever I would pick the kids up in the roadster from the grade school, Roy would pop out if his bus to admire the car for a few minutes. A great guy— sure miss our chats…Michael”

 

Michael connected the dots for me….Christine’s Dad indeed worked for Jack Scoville, the racer who gave Nissan their first national championship by winning the 1969 SCCA run offs at Daytona in a 2-liter Datsun Roadster. The Datsun Destiny got even better as I learned that both Michael and Christine attended the same high school in Corvallis.

(Above) Christine and daughter Audrey heading out for a Sunday drive. Visiting Mt. Umunhum when it first opened.

Christine recalls her Datsun story and eventual 350Z ownership:

“My dad started working at Jack Scoville’s when I was 5 years old. He had been a high school art teacher and then quit to sell motorcycles and finally ended up at Jack’s for the rest of his career. I would help out on the car lot. Back in the day, he would have to go around with a huge ring of keys and lock up all the cars for the night. I always had fun doing that job. At the time Jack’s son Jeff was still racing and took me out for a ride in his race car.

My dad had ordered the 1970 240z, but my mom had become pregnant with me and when it arrived on Jack’s lot my dad realized there was not going to be any room to carry me in the car and ended up getting a Volvo. He finally bought his first Z in 1990. He purchased the 300ZX in white with the T-top. Then in 2004 he purchased the one I have now.”

Enjoying The Ride

 

In addition to our race efforts and early-Datsun support, ZCG’s daily operations include routine maintenance and modification for the 2003-2008 Nissan 350Z as well as 370Z sports cars. With only has 47k on the odometer Christine came to us for a full inspection. We wanted to ensure the car would be ready for the next generation of Z car enthusiasts….Christine’s kids:

“My dad loved cars and motorcycles and cleaned them all with q-tips. When I was 4 years old I was responsible for scrubbing the wheels and tires. And as I grew older I was giving interior detailing duties with the q-tips. I have now passed those skills onto my son. It seemed an unnecessary luxury to keep my dad’s car, but he always drove it when he came to visit so he could drive Nathaniel around. Nathaniel has the best memories of long drives with my dad in that car. Nathaniel and I have kept up the tradition with long Sunday drives. He is also in the process of getting his driver’s license in the next six months and can not wait to drive it on the road.”

We made a plan to perform general services plus a few little touches plan for service to make the Z more enjoyable.  A very common problem on the 03-06 z33/G35 is in the valve covers;  the spark plug o-ring seals will dry up over time and allow oil to leak into the well eventually compromising coil pack performance. The valve covers and and valve cover gaskets were replaced along with new spark plugs and new drive belts.  All fluids were replaced and the car got received full 50k services. All this family needs is to Enjoy The Ride:

 

Making the Z fun to drive are a few popular performance upgrades including the JWT POP charger intake and Hotchkis sway bars front and rear:

 

Front T/C rod, control arm and diff bushings were replaced with new units from Whiteline. The diff bushings are the most common failure as see in previous blog posts. Christine’s Z also had a CV axle click–this occurs when the splined axle shaft gets dried up without lubrication. We took care of that and installed a new set of tires followed by a full alignment:

 
 

Icing on the cake was a dyno tune. Rob UPREV tuned picking up power everywhere in the rev range for a total of 254hp/250tq to the wheels, gains of+9hp/8tq. This is a great example of having a proper tune to maximize gains from your bolt-ons whether it is DE, Rev-up, HR or 370.

 

 

 

Love Cars. Love People. Love Life

Mr. K’s motto is what we Nissan/Datsun enthusiasts live by. We enjoyed working with Christine’s wonderful family and she is stoked with the Z:

Our experience with ZCG was amazing. It was personalized to our needs. Rob is an expert in what he does and gave great suggestions based on how we want to drive the car. We were very fortunate to find ZCG through a web search. When I inherited my dad’s car and after having it here in California for about 3 years, I knew I wanted to get it serviced and keep it in tip top shape. It had never been stored outside of a garage. Once we got it to our home here in California we cleared out space for it in our garage.
My dad had owned the car for 13 years before he passed away. Over the years I had driven it occasionally. Nathaniel and I kept up my dad’s Sunday drive tradition and took it out each week for a spin. After getting serviced at ZCG it runs like never before. Everything is so smooth and quiet. I don’t even know how to describe it. We all agree it purrs.”

 

Thank you for your support Christine and Long Live The Z!

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!
