I'm thinking about getting Cosworth 272's for my Mivec (stock rev limiter), Forge Wastegate Actuator, ETS UICP for the stock battery, Walbro 255 Pump, Exedy Twindisc, New Injectors (not sure what CC yet), new ams fuel rail, head studs, and a AMS retune. How much power do you think i will benefit for this costly mods. With my mods now in my signature i got about 330 AWHP. How much more do you think i can achieve? Please be nice.

 

The cams will add some power and tq. Get the twin disk when your clutch goes out. The other mods you will see little gains from what I read. When you upgrade your turbo all those other mods will be more useful, but for stock turbo not all that needed.

 

Cosworth 272 - Yes
Forge WGA - No. Only if you're getting FP Green + High Boost (25+)
ETS UICP - Yes
Walbro 255 - Yes, long overdue
Exedy Twin - Maybe. ACT Xtreme Street is much cheaper and similar torque capacity.
Injectors - No. Only if you're getting a big turbo
Fuel rail - No. Only if you're getting a HUGE turbo
Head studs - Maybe. Only if you're getting a big turbo + running high boost. You will have to pull the head and replace the head gasket.
AMS Tune - sure, why not

 

i agree with everything you say but i think his turbo ,will hit a little harder with the upgraded wga.......and hold boost better i have a 16 white rabbit turbo and when i added the force performance wga it hit much harder ....correct me if im wrong....

 

im hearing the same thing about the wastegate, ok maybe the injectors and fuel rail are a little riduclous, but thanks for the help guys !!!

 

forgot to say im getting a 02 housing !
