With the evo3 i would need to get the evo 02 housing and such b/c there is a 1/2 inch overlap or get my current one ported. I really just want to get my car running and I think Ill be happy with the big 16g. My goal for the car was low 13s and I think that is pretty possible with the big 16g. It may be stupid in your eyes but its my money Also DSTGST no offense but I didnt feel like going through a middle man. I was ready to order it at the time and didnt feel like waiting to get in touch with you. But thanks anyways
