Here is Rob to bring you a Vortech-Supecharged G35 update:
Deric is a mathematics teacher at a local high school and owner of this 2005 G35 coupe. I met Deric at ZCG and he was ready to increase the G’s performance or move up to a GT-R.  I let him know that the GT-R was amazing but he could certainly turn up the boost (pun intended) on his daily driven G sports coupe. We arranged a time to meet and made a plan for success. We hooked Deric up with a Vortech Supercharger and supporting cast of headers, cams, full exhaust system, and a ZCG oil cooler.


A full complement of DEFI Gauges in a color-matched gauge pod were added inside along with a custom mounted Link unit.

After a few weeks of tearing up the streets Deric’s automatic transmission started to disagree with all of the new horsepower and torque being produced. A plan was made to build Deric an “All out war” transmission. Sam at GTM was given the order and funds to proceed with a built gearbox. During a short few weeks at the wheel Deric noticed that the G was having trouble keeping up with the power….Slowing down became harder and the tires had this issue where they would smoke when smashing the gas in the lower gears. You will never guess what happens next…Boom…Axis wheels and Stoptechs all the way around for this bad G!!!

Next in line was a Stillen front bumper upgrade to get more air over that intercooler during the hard runs from light to light…Deric’s G had become a 3-Dimensional Sportscar enthusiast’s dream.
Before/After Axis wheels, Stoptechs, and Stillen front bumper:

Big power, crisp shifts, traction, and stopping with ease….Any student or faculty member leaving campus didn’t stand a chance…From time to time I would hear reports from Deric on how much he was enjoying his ride. He even bought his wife matching wheels for her Z. This family is serious about Nissan performance.
Latest news on Deric’s G…We switched engine management to UPREV, installed 600cc injectors and a Pmas MAF. All of the Vortech FMU components were removed, and the fuel pump and supercharger pulley were upgraded for more boost goodness 🙂
Dyno plots below showing the stock motor: 215hp/211tq, initial Vortech tune: 355hp/295tq,  and final tune: 388hp/311tq at the wheels.


Deric ‘s G is driven daily and this G is HOT for teacher!!!

Ken P has been a Datsun roadster owner and enthusiast since the early 90’s. He’s an original member of the Bay Area Datsun Roadster Owner’s Club (BADROC) and owns this highly modified 1969 2000 Datsun roadster, affectionately called “DATSTER”. Ken brought his car to ZCarGarage to get tuned, but let me share a little history with you since it has a special place in my roadster heart.

 

I met Ken at the Solvang Datsun Roadster Show back in 2001 and remember seeing all of his modifications for the first time. What really caught my eye was the paint and bodywork. Shaved door handles and side markers, no door or vent windows, and beautifully applied BMW Technoviolet paint really turned this into a hot rod. The interior was simple with no center console, re-uphostered seats, and a roll-bar. Over the years Ken kept adding his own touches and personality to the car including a trick hidden antenna and HID Xenon headlights adapted from a late-model BMW.

 

Under the hood lay Nissan’s mighty U20 drivetrain complete with several period go-fast parts like Mikuni-Solex side-draft carbs and a hotter camshaft. 14″ Panasports on sticky A032R tires and a full NISMO competition suspension made for a very fun little roadster.
I almost bought his car from him about 8 years ago but fate and the fact that Ken just can’t leave things alone led him to the next level of the DATSTER’s evolution. He removed and sold the U20 setup and with the funds(and money left to spare) purchased and installed a Nissan KA24DE drivetrain from a 240sx. Ken did the installation himself and added a few more custom touches like a metal dashboard color-matched to the body that houses the 240sx gauge cluster and S13 (of course!) seats.

 

Ken continued to drive and enjoy the new KA setup by doing fun runs, autocrosses, and even drag race events.  He wasn’t done yet though and decided to add boost to the motor in a rather unorthodox way: supercharging! A supercharger setup was sourced from a race car and Ken made numerous modifications to make it work in his engine bay.  The blower is mounted just above the frame rail but hidden under the intake runners. A custom throttle-body and pulley system were necessary.

 

Rob and the crew at ZCarGarage have worked on many roadsters, from bone stock to modified. Ken came to ZCG because he wanted to make sure his supercharged engine was tuned correctly for longevity and power. Baseline numbers were 159hp/156tq, and it was definitely in need of a proper tune. Rob and Clark Steppler tuned the roadster using a JWT ECU to safely boost at 8lbs and make some great power: 180hp/171tq at the wheels!!! The dyno plot reveals the beauty of a roots-style supercharger: a broad torque curve with over 150tq available from 2000rpm to 6000rpm! We think Ken is happier now 🙂

 

So with all of the ingenuity, modifications and big power is Ken finally “done”? Nope. He is currently engineering stronger brakes that will fit within those classy 14″ Panasports. Datsun owners are truly one of a kind!

 

Here are a few clips of Ken’s supercharged roadster in action and many more pictures in the gallery, enjoy!
