BACK IN 2007 LOL We were pleased to announce our latest accomplishment, As many of you know we have a 4.24L Z shop car that you have all been anxiously waiting to see what we do with it. Last night I decided to pull a 24 hour shift and begin tuning our beast. The engine had almost 1,000 miles on it and I felt was ready for some Dyno time (breaking in the engine properly is VERY important for any built high performance engine!) I started at 12psi and ended the tune SEVERAL hours and countless Dyno pulls later at 20 PSI, all the way to dawn
The last run for the night ( run #43, that's right 43 back to back Dyno runs in one night/morning!) yielded our goal of 800rwhp, on 105 octane UNLEADED, on a very conservative tune. As stated before our number one priority is to have our engines LAST! Anyone can make power on a Dyno, but not everyone can make it last in the real world. The car was very stable at these power levels and I feel we have more room left to push. As a matter of fact we will be driving the car today to Auto Crave 2007. After a few thousand more miles on the car and some real world condition tests we will be back on the Dyno with some C16 and Red bull ,

350z 4.3 Liter Stroker Engine APS Extreme Twin Turbo First Start-Up
After 3 weeks of doing the 6 speed swap and the 4.3 liter swap we are here. We were trying to get oil temp and pressure up but ended up springing a leak in a custom stainless steel radiator hose.
A little bit of noise is coming from behind timing cover. Hoping this will clear up after about 15 mins of 2-3k RPM. We were trying to do this, but the SS hose came loose. This is on just a custom start up map by Injected Performance.
350Z HR Twin Turbo Dyno
This is our 2008 350Z shop car. The internals of the motor are completely stock. The only mods to the powertrain are the GTM stage 2 twin turbo kit and dual 3" Exhaust.
This was with a very conservative tune. AFR's were in the low 11's/high 10's, and we hadn't even touched the ignition timing.
Nissan 350z 3rd Gear Grind Transmission Problem
This is little video clip that I made before I drop off my car at the dealership. Hopefully they'll fix my transmission for free. This is 2003 Nissan 350z Track Edition. It grinds almost all the time when I shift into third gear normally and in order to shift without grinding, I have to shift really slow until my rpm drops causing my car to jerk.

I had a extended warranty and they covered for repair cost and parts. It was bad syncro on 3rd gear.
