Maximum Response Setup For Rb25

[jjman]

Cool thread, kinda along the lines of what I'm doing - subscribed and will share my results along the way

Hoping for a close to stock response 230-240kw, which will be exactly what I'm after

My setup will be -

HKS 2535 turbo, hoping to run around 18psi (have turbo but not installed yet)

Split dump pipe - installed on stock turbo at the moment, quite a decent length split section

Nistune - installed

Autobahn88 intake pipe - installed

Injector wise, im either going to use a set of R35 GTR injectors, from what I've been able to work out they are 560cc and direct drop in, or a set of larger injectors if I wanted to go E85

I'm guessing the stock AFM will need to be upgraded to a Z32 or R35 GTR unit

Look forward to seeing the OP's results

I had exactly this setup- particularly the turbo. It is a great turbo and I really enjoyed it. I had 17psi at 3250rpm. and it come on smooth and holds boost well. But for the HKS price tag you often have to pay for them id say you would get the same if not better results with a Hypergear turbo. ALso if you kill the HKS you have to pay the Garrett price tag for a new CHRA. If you already have it- enjoy, it is a damned good turbo. If not, spend on a HG highflow id say.
