Which turbo of these 3 need to make a decision ASAP
 

Okay so i have a forged 2.5 STI the current mods list is as follows

Hybrid FMIC
AEM long ram wing mount induction will be swapping to RCM 80mm soon
750cc injectors
GT spec gen 2 headers/ uppipe
full 3" turbo back Miltek system (backbox changed to an Afterburner raptor)

I have the following 3 turbos to choose from all around the same money

56mm intake MD321V
76mm intake ATP gtx3071
76mm intake RCM 400

I am after 400/450 BHP which one should i pick ???

For a 2.5 the 321v

Deffo a 76mm intake, I run a FP Green turbo with 76 mm inlet on my Bug STi. With mods it showed 440 bhp on Scoobyclinic rolling road, the engine internally is standard and has covered 110K miles which I can confirm as I bought the car new.

The V is a 500bhp turbo, the mdx321T would be better suited to your goal and would make for an awesome point to point car on a 2.5 engine

I run the FP red , I use there own FP 84mm intake , there turbos are great value for money I think :thumb: ,, good to find another person using a FP turbo as there doesn't seem to be many in the uk

So its between the Gtx071 and the RCM 400 i would like upto 450 but if it makes 420 i would be very happy, which one do i choose ???
