Hi guys

I've got a 2005 sti ppp , it's running the standard ppp map ATM with forge recirc valve and k&n typhoon , it's also running prodrive dports cat and centre section with a blitz nur spec back box , so it's 2.5 through to backbox with 3 inch from there back

I'm going to get the car mapped but want to do a few bits first to get a decent result , so I'm looking at mods to get me over 400bhp

What are my turbo options / costs ?

Injectors ?

Other related parts to get the power wanted etc

Just after some "package" examples really and rough expected gains so I can judge what's worth it and what's not

Thanks

 

Im at 397 bhp on a billet 321t, 800cc injectors and prodrive sports cat, fitting an induction kit today and them map on friday, hopefully that will get me over 400bhp.
