Any advise would be great
My R33 gts-t is running 322bhp (see print out)
with Fmic, 0.85 boost, Apexi induction kit, and cat back japspeed 3" exhaust.
Ive just treated myself for xmas (thats what ive told the missus) to:
high flow downpipe with 1.5'' divorced waste gate primary
de-cat pipe
0.8 iridium plugs
z32 afm
Apexi safc2
walbro 255 fuel pump
short shift kit
........................................................................................................................
If i was to buy a fuel pressure regulator would this uprate the standard injectors anymore?
what bhp is acheivable with these new extra mods and the safc2 correctly tuned?
The next mods are going to be big money e.g turbo, manifold, injectors, coil packs, ecu, headgasket ???? ££££ ????

Z32 isn't needed until you upgrade the turbo, only thing thats going to see you some extra gains is the Downpipe and de-cat.

Forget the safc 2 and save it for a bigger turbo, then along with new injectors and the Z32 fit it all and have it remapped.

The adjustable fuel pressure reg also isn't needed.

you dont need a adj fuel regulator even up to 650bhp

you dont need a different manifold

no point in fitting the z32 yet untill you want 400bhp+

oh and the divorced turbo elbos cause boost creep so keep the oem one

like bruce says the safc2 aint really any good apart from watching knock

next time you go and buy stuff ask on here first before you do or you will prob end up wasting money

That's not a bad dyno for the mods you have.

Have you got a remap???

Was about to write that actually lol

Not sure about the re-map?
The bloke i got it from told me very little but i managed to get intouch through another forum with the person that imported it........they tell me it had a laptop wired up in the boot (still got a serial cable behind radio) and a screen in the front! they told me that the laptop didnt work.
I hasten to add that when i bought it......no laptop or screen with it so i,m not sure about the remap question.
I,m just running it on what i think is a standard standard ecu running 0.85 bar

I have one of these fitted to my R34 GTT and a de-cat pipe mate.
Rest of the exhaust is still std for now.
It's been on about a year or so now.
I have not experienced any boost creep,but still set at 0.6 factory setting.
I find that the turbo spools up a bit quicker thats all.
May i have a reason for your quote please?
If it is 100% correct then i may resort to OEM.
Thank you from Neil.

I got slated on another forum for posting up a dyno result of 299bhp saying I couldn't possibly get that with the mods I have.

You have what appears to be less!!! Then me and no de cat, Although I would suspect a re map with those figures.

I now you should take dyno reading with a pitch of salt but good stuff and these guys REALLY do no what there talking about.
