Now Will All of those turbo's bolt strait up? Also whats the gains of getting a manifold from Fp with stock fitment? Does it aid in making numbers?
Looking for 500-600 BHP NOT WHP But is for a daily driven car & street racing so ideally not up for a lot of lag! I want a nice powerband i can raise my RPM Limiter if i need to no problem i don't think also running a Evo5 Ecu

All help massively appreciated, also anyone got any dyno graphs or more detailed info for me would be grand
