I have a 99 si with intake, DC Sport 4-1 Header, and WS2 cat-back. Looking for suggestions on what to do next????(eventually going to turbo within next year) But im Thinking about converting to OBD1 ecu and chipping it first?????

 

sounds like a good idea, i say go for it.

you could also start investing in lots of condoms cause turbo si's get all tehsex.

 

What ecu do i need to run ?????
