So I pretty much wanted to swap my na, people say it easier buying a twin but I got the na already and as far as I know there isn't much work that actually has to be done as in doing the swap. I know ima need a twin engine and ecu but as for everything else the whole rear assembly doesn't need to be changed right? Maybe wider wheel base and bigger brakes.... Tranny works and I would like to say better because of the gearing. But as for that what else is gonna either have to be moved or switched from the turbo version to make the engine work with na tranny and as much as I could use from that?
