Im currently in the process of buying an 05 -55 plate V8 sti.

I have started saving away for tuning and this is my list so far which i have 2K to spend:

RCM exhaust 3" bore Decatted system from uppipe to back box.
K & N typhoon air filter
Walbro 255 fuel pump
Remap

also im thinking after a bit more saving as september should see me with a futher 2.5K:

650cc injectors
MD321T turbo
FMIC.

What sort of power would i be looking at with this set-up?

Also i have 3K stashed away for a rainy day, is it worth going down the forged route?

Thanks

 

You need a new clutch for the MD321t but a good choice and I would say a 450 of each as a rough guide

Don't fit the typhoon and the walbro. Get a proper RCM big maf filter and get yourself a bosch fuel pump as they are the better products in the long run and will save you cash

 

Is it worth going down the forged route to make sure the engine is bulletproof?

 

why waste cash when the STI engine is proven to 450bhp. I would take my chances and see what happens At worst is a rebuild
