Hi guys,
I'm in need of some advice and help.
I have a 32 GTR which had the following mods:
Kakimoto GT1 OZ Racing Exhaust
Vortex front pipe
R34 N1 Turbos
Apexi Hybrid Intercooler
Forged Pistons
Nitto Oil Pump
Tomei Cam Gears (dialled in, cant remember though)
Some Japanese chipped ECU
boost tap (like a boost tee)
When these mods were on, the car made about 260kw on the rears.
It would peak at 20psi and taper off to 18psi.
I had it dynoed at at different tuners about 4 months later and it put out 235kw ( this is not the main point though)
These were both on Dyno Dynamics Dynos.
However about 3 months later, one of the intercooler pipes started to leak and hence I did these mods to it:
JJR hard pipe kit
Z32 AFM
Blitz Dual Solenoid Boost controller
Sard 700cc injectors
New NGK iridium spark plugs (correct gapping and stuff)
Tomei Type A camshafts
NISTUNE ECU
When it was getting tuned, the stock BOV's couldn't take anymore than 15psi and as a result was forced to use 2 HKS SSQV's i had lying around.
The power curve was like a wave up top. The BOV would just open, close, open ,close until red line.
The SSQV's didnt fair any better and only held 16psi. with the same waving problem.
This time it was tuned on a Mainline Dyno and pulled 260kw on the SSQVs.
I am however very annoyed at those BOVs and want to go back to stock ones.
However cannot understand why the stock BOVs handled 20 psi if not 18psi with no problems on the previous setup but cannot handle the boost now.
I plan on upgrading the puel pump next, but i dont want to take it to the tuners, pay for it and get the same result.
I want to break 300kw and im very confident that it should, with an upgraded puel pump.
Right now the car doesn't feel as alive as it did when it had less mods.
Any ideas?
Thanks in advance for help.
