reading some new posts and heard that r32 gts-t already boosts at .8bar, is this correct, if so is there any point gettin a boost controller till i get an uprated turbo

also, if i have

cat back (currently on)
de-cat, downpipe, turboelbow etc
manifold
hks induction (currently on)
and fmic

will it overfuel the car, from what ive been reading i think this may be the case, so should i then have the car mapped?

also what do you reckon the car would run? bp and tourqe wise

cheers all

hi johnathan.....the standard boost is in 2 stages 1st stage is .4bar and second stage comes in at around 5,000rpm is .5-6 bar, if you put a boost controller on it will enable you to increase boost to .85bar and with those mods yes it will overfuel, you can put an apexi-neo (piggy back ecu) on and that will deal with the overfuelling and give you more power.power wise 270bhp i guess. richard at rising sun will supply you a apexi and re=map it if you need to mate....:D

I think Bigchief misread the post. Only the R33 has the 2 stage. The RB20 just boost to .8 bar. The stock turbo has ceramic internals so that's as high as you want to go. If you fit another turbo with steel internals, you'll be able to go up to 1 bar, or higher with supporting mods. The HKS 2530 seems to be one of the prefered turbos for the RB20. From what I read on various forums, it's matched very well to the engine.

so there would be no point in a boost contraoller until i got the uprated turbo.
you know what bar can be put through the hks 2530 with sufficent engine mods to cope out of intrest? will this be as you said 1 bar?

and also, if i just got the ecu remapped, what would i be looking at as cost compared to apexi and remap?

would having the full exhaust, induction and fmic cause the boost to raise?

i have heard peoples boost raising when they fit an exhaust for instance, and thus would this be dangerous? if the gts- is already so near its limit.
