I have a 95 ex with a d16z6 in it. Without swapping for a B16 or doing and major engine work, what can I do to it to give it a bit more up and go. I Just put on a cold air intake and exhaust is next on the list.... ANy other suggestions like injectors or manifolds or anything? And to turbo it does it only take a bit of head work? Oh yea and my car already has 125k on it. WHat would you guys recommend for a decent exhaust? I really like the sound that apexi puts out but Its a bit more pricey. Are DCS 4-2-1 headers good?
