Power Limit Of Rb25 Afm?

[snozzle]

Hi guys im thinking of putting an Apexi AX53B70 turbo (P25 Rear housing) i have lieing around but my budget is abit tight at the moment so my question is, do I really need a z32 afm to run this turbo such that i can make about 350hp?

if not, how much power will the stock r34 neo afm cap me at?

ive been reading up on it and i keep reading different power levels, close to the 300-340mark but id rather find out if anyone has made 350 on a stock one before

you will need Z32

[blaikier33]

i maxed mine out at 280bhp, @14.5psi. so you may need one

300 would be the max but you can tune past that, not recomended but some tuners will.

I'm putting the very same turbo on my 33 in about 2 weeks time with a tomei fuel reg.I'll let you know how it goes.I plan on putting a z32 afm and bigger injectors on it in the future but i just can't afford it right now.I'm afraid that if i try to wait and save the extra money needed,the turbo will never go on the engine due to some unforeseen circumstance.I have the money now to put it on and get it tuned but it would probably be another 6 months if i saved for the injectors and afm.

Slap the turbo on and tune the car to the max potental of your stock injectors, then its a simple tune tweek as you get your afm and injectors. exactly what i have done. I have a hypergear ATR28G4 on a midly modified r33. running .7bar actuator on stock ecu. i have an rb20ecu with nistune ready to fit. next step highflow injectors and z32

you will eventually need a z32

ps you are going to love this turbo, i had one on my rb25 in a r32 and it was amazing!

i was running 350 on a stock r33 afm (doing about 330 now). it can be done BUT if you can afford get one. or a very good tuner
