hey everyone i have a 97 eclipse GS. I found a T3/T4 Turbo kit online i was thinking of buying. the kit has everything i need but my question is if i buy it, 1. will i need to buy anything to replace such as like o2 sensors or a new radiator or anything really. i ask this cuz everytime i go to auto zone or napa they narrow down my part by asking if its a turbo or non turbo. so does it really matter. also if i bought that turbo would my car pass smog. if not what is a good turbo that can pass smog that is aroung 700-800. thanks eveyone
