Need Some Input On Hks 25/30 Turbo In Rb25

[Duy]

I am thinkng of upgrading the std turbo for a 2530, as it is a street car, I am looking for a little more power. What would a hks 2530 put out at the wheels with pfc 550cc injectors? on max 16psi boost or lower?

What engine do you have? 2530 is a good match for a RB20 as is a RB25 turbo.

For a RB25 though a 2535 is a better match, Plenty have taken the 2530 route with a rb25 and had good results up to around 230rwkw, 2535 would net you around the 250rwkw mark. For a RB25 you should also consitor the GCG highflow (currently in groupbuy section), HKS GTRS, or HKS PROS best prices I have seen on HKS units are at www.nengun.com.

opps sorry! just read the title you have a RB25.

2530 turbo won't give you heaps more top end than the stocky but will give you a shit load more midrange. Expect around 220rwkw at the wheels. 2535 will give you an easy 230-235rwkw with again some good midrange as well. Either turbo is good, i had both on mine.

If you want higher dyno numbers , check one of the other turbo, GCG's etc, but havent seen any beat my 1/4 mile with the little HKS yet.

Sounds good, when did or does the boost come on? with the 2530?

I think i was getting full boost (20psi) by about 3500rpm
