What Next?

[Luthor666]

ok im trying to turn my stock r33 GTS-T into something more powerful and i understand that when you hit a certain kw rating things need to be upgraded or replaced. ive done the usual mods exhaust, turbo, intercooler etc. but now ive come to a standstill and dont know what to do next and whether large mods like forged pistons, cam gears or gearbox modifications are even required at this stage or if they are even necessary. so heres what ive done so far

Splitfire coilpacks

front mount intercooler

exedy hd clutch

turbo upgrade (GT-RS)

Apexi Pod filter

Apexi mkII evolution dual exhaust

hi-flo cat

stainless steel front and dump pipe

GOING IN NEXT WEEK:

Apexi Power fc +hc

SARD 850cc injectors

NGK iridium spark plugs

Z32 afm

everything else is stock at this stage, im thinking fuel pressure regulator next or at the same time as the injectors. in what order should i do these

ps: im not interested in any1 willing to take the piss out of this as i am new to the industry!

Kyle, how long have you owned this car and what did you drive previously?

[Luthor666]

it was my first but it was completely stock when i got it then the stock turbo blew after about 8 months then it was modified. ive had it since march 2008

you pretty much have all you are going to need for that turbo. no real point building the motor as you shouldn't have any issues running that turbo on the stock internals. also no point getting a fuel pressure reg. thos injectors may be a touch of overkill though. 750cc ones would probably be a bit better (bigger injectors sometimes make the car harder to tune a steady idle).

but you pretty much have everything you need. you have the intake sorted, you have the exhaust sorted, you have the clutch sorted, you have the turbo sorted, ecu sorted and fuel sorted. probably only other thing i would suggest is getting a fuel pump put in at the same timeas, or before, the tune is done. oh and a boost controller to wind the boost up. no point having bigger injectors if the fuel pump can't supply enough fuel once you wind the boost up.

oh and you didn't mention a boost controller. get one and then screw the boost up to about 18psi and you should see 250kw easily (so about a 50-70kw increase on what you currently have)

[BoyWhoCriedWolf]

Pretty much what marco said, tone down the injectors, beef up the pump (040 or 044 would be fine).

oh i forgot that i do have a walbro 400hp fuel pump :\

does the APEXI pfc hav a boost controller in it? or do i have to get like a profec B

[mad082]

you can get a boost controller for the pfc. partly depends on what the wastegate is set at on the turbo and whether it's adjustable or not. if it's adjustable then just use that. personally i'd just use a turbotech manual boost controller. it's cheap and works well. i'm not a big fan of electronic boost controllers. way too expensive for such little gain.
