I'm saving up money to buy a TT front clip from Z1. But b4 i do that i have to ask a few questions. 1. It says ECU and MAFs are not required in the conversion. I would suppose that meant that they came with the clip. Is this assumption correct? 2. Is there any thing else I'm going to need upon purchase of this clip. Or is it good to go? 3. Is the reliability on these JDM motors up to par? 4. How am I going to pass emissions?
