ohs nos....




nice build for 2004. and im glad its still runinng but that car needs some tender loving care and upgrades now. those number seem really high for what you have.




But 18psi twin 18gs and 750 RCs does NOT equal 600whp maybe 550....... and why the FUCK would you have a utec anything above 550whp... that is just plan scarey to say the least... in 2004 there was F-con V-Pro a minium for 550whp Zs and Gs... dont mean to bash but seriously its 2008 almost 2009... ungrade that EMS to haltech or F-con at least. and those injectors are probably maxed out... you have the fuel pump system(AAM) but not need for anything below 1000cc.


get some 275-305 toyo R888s and that power will hook believe me. it will hook about 75-90% in first and all in second...


Nissan Sean WTF! GTFO noob that intercooler is good for just about anything those stock 18Gs and the upgraded 20Gs can push out. please dont talk about performance about the Gs and Zs please please i beg you.

YOUR dead on you know your stuff here is what I got..

I have it set at 18psi and pump 93 which explains the daily drivability of the 350Z I put down 507 WHP and 500 ft/lb TQ at 15 psi on 93 octane pump fuel. RE dialing the BLITZ SBC-id dial and resetting the (AS YOU SAY PEICE OF SHIT UTEC) produced 565 WHP and 576 ft/lb TQ at 18 psi still on pump gas.
With VP Fuels C16 in the tank and the 18g’s at full, this white 350z puts down 624 WHP and 674 ft/lbs TQ at 24 psi.


The turbos were modified by carv2 we discovered an exhaust “bottle neck” in the design of the Greddy waste gate placement.
For up to around 14 psi, it wasn’t an issue, which is more than enough for most users. Once we dialed the pressure to 18 pounds, the problems appeared. The way Greddy has the exhaust recirculation path entering back into the stream at a 90 degree angle, caused a very strange boost response.
The two exhaust flows were fighting each other. To eliminate this issue, we completely replaced the turbocharger outlets with full 3” down pipes and relocated the waste gates. The waste gates now have atmospheric outlets and command attention under full load.


YES YES I know....i cant do a perfect build everytime.... but this car is for sale and the price is low enough for whom ever buys its to do some small mods.
I want to get back to my skyline..... But before it sells email me some info on those systems your right the utech sucks misfire codes unless your running 110 at all times

Utec is like considered my first EMS to the VQ boards. the interface is .... to say the least is archaic. transition from vacuum to boost can be... problematic, and rough. and as you know misfire codes, and maybe hot start ups. the 16x16 resolution is well... 16x16 a little weak for 500+hp F-Con V-Pro and Haltech is 32x32 which you can lower to 16x16 or 8x8 if need be...which for boost more is better. i highly suggest you dont take those turbos over 20psi they fizzle out anything close to that. your just cooking the air and not really gaining anything other than high intake temps.

The wastegates have been known for about 1 bar before you need open dumps or relocation of the wastegates to further down the exhaust. thats a old old problem, its like common knowledge now. if you havent had a quality tune in the last 6 months or ever really... id just run on wastegate for now. or maybe 12psi depending on your springs.

WHAT DO YOU RECOMMEND>>>> Tune wise
I took it to Z1 last month and they said that I would be wasting money because my air fuel is dead on and after testing it with 110 they said it is running strong. this is a 2003 but keep in mind it only has 20k miles on it it has been treated like a baby. But I do need to dial in the SBC id that I am still learning.
