Ive had my55 sti for nearly a year now and the warranty is nearly out so i want to start playing the BHP game. I am looking to get it to about 330, and im not sure to take it to a place like scoobyclinic , TSL or get a mapper like dynamix take a look at it. What bits do i need to get if i was to go down the mapper route? any advice appreciated

 

100 CEL Sports Cat DP
De cat Center
uprated panel filter
Decent spark plugs
Remap from the like of Duncan at Dynamix
Some might say 3port boost solenoid as well but this isn't a must!

330 bhp easy, more like 340bhp

You can do all of the work with the exception of the remap yourself

 

What about a fuel pump?

 

ah yeah + the Walbro 255lph or some thing like that was bound to miss something

 

Ok great, Do i need to have the sports cat in the DP and do i need to get a 3" system all the way through? I have a H&S back box on the standard system at the moment.

 

Sell the H&S back box and buy a full 3" system with decat center mate

Yes get a 100CEL sports CAT in the DP, this will save you loads of agro at MOT time and you will lose very little BHP from the sports CAT

 

Thanks for the advice i will start getting some bits together.
