Currently have a '04 STI with PPP.

Apart from a remap of my standard ECU (will this still be adequate) whats the best way to start on the road to 400BHP??

I have just purchased a full 3" decat (got it cheap, just hope you don't all tell me I should get a 3 1/2"!!)

Will my standard TMIC suffice, or will I just need a larger TMIC or do I have to look at a FMIC?

No more questions I'm going dizzy again, hence the plea for help!!!!

Thanks in advance people, much appreciated

Turbo, fuel pump, bigger injectors, uprated hoses, TMIC can suffice but reliability can be compromised on a uk car with 400 horses....

Will my PPP fuel pump (They are Walbro's I believe) need replacing?

What size turbo, would a TD05 20G be required or would an 18G do?

What size injectors would be required (what do I have now?)

Which hoses need uprating?

Thanks Tony

A TD05 20g turbo,performance manifold inc bigger uppipe all wrapped,cold air induction filter and a good remapp should get u there or abouts

Who does a decent unequal length manifold and uppipe at a reasonable price, I had an equal length one on my classic but it meant I had to remove my engine undertray and lost my Dubba Dubba rumble, neither of which I want to do again.

Nice one.

Your fuel pump will be fine already uprated with ppp,im sure your injectors(550cc)should be ok but u need to check with the experts like Jolly green monster,Zen performance and Andy Forrest all 3 are extremely helpful and will know exactly what u will need to get 400bhp

I got my manifold and uppipe with a good quality heat wrap included from zen performance,its well made and sounds really nice 2
