It is a small world when it comes to the Datsun community and we love being a part of it. Jobie brought his Datsun 510 to Z Car Garage for dyno tuning on referral from our good friend and overall-stellar Datsun dude, Troy Ermish.
Jobie’s Dime didn’t always look this pretty, as shown above left running a single carb Z24. James Johnson applied the paint and a year later the car was dropped the car off to Troy for a L20b/Mikuni 44 engine. Ermish Racing prepped the chassis with parts from Techno Toy Tuning on the front suspension, Troy’s Wilwood brake kit and bespoke rear suspension parts. We are smitten by the stance on this thing, sitting perfect on nicely spec’d 14″ Hayashi Street wheels. Great choices in the interior too:
On the dyno we saw peak gains of 8hp/4tq for a total of 166hp/157tq at the wheels. The real improvements can be seen under the curves with consistently more hp/tq throughout the rev range:
The car is setup from open track enjoyment yet still street driven:
“I always heard Troy talking about bringing cars over to Z Car Garage for a dyno tune. I try to get the 510 on track ever other month or so. So far, it’s only been to Laguna Seca, but this year, I’m planning on track days at Sears Point as well”

Scott B was the first Nismo 370z to be supercharged down at Stillen. After a few years and 25k miles he came to Z Car Garage because the car was acting up. Rich A/F ratios from the (early) Stillen tunes had fouled the catalytic converters.
We installed ART pipes which are test pipes without the traditional raspy sound:

After the install we re-tuned Scott’s Z picking up 17hp/14tq for a total of 416hp/313tq to the wheels:
Tom H has been coming to Z Car Garage with his Salt Flat Crew for many years. We helped tune their early Studebaker and Sprint cars that went on to make several record passes.
Tom has owned this Cobra since 2000 and he replaced the small block with a 427 fed by four Weber carbs. For the last two years he was fighting driveability issues. Rob found the transition between the pilot circuit and main circuit had a big hole in it and the car would fall flat on its face under wide-open-throttle, eventually catching up with itself.
After ~20minutes on the dyno Rob turned a stumbling car into a totally driveable beast making 404hp and 480 tq to the wheels!
Phillip V is a Z Car Garage customer and former 350z/current 370z owner. We installed an Injen exhaust system on his 350z and he absolutely loved it so naturally he wanted one for his 370z. We didn’t sell these exhaust systems for the Z34 and this was our very first install. Here is a before/after:

On the intake side we added JWT dual Pop chargers:
Dyno Tuning
To maximize gains from the bolt-ons we UPREV tuned the Z. We started with 284hp/235tq and the JWT POP chargers made a significant increase up to 294hp/241tq:
The Injen exhaust was good for ~4hp/3tq for a total of 298hp/244tq:
UPREV tuning yielded even more power for a final output of 311hp/258tq to the wheels, gains of 27hp/23tq to the wheels:
