I have an 05 MZ3 and want to put a turbo on it, what is everything needed in order for the turbo to work properly have right airflow and gas flow, and have all the sensors and gauges. Everything.
to be completely honest, it sounds like you are not hugely knowledgeable about this and would probably be better off just selling your car and buying a used MS3. I've seen ones that you can pick up for like $14,000. That seems to be a better deal than a turbo 3 because you are starting from a better platform...
Yeah that is quite the list to put together. Tri-point sells great kits. Or you could piece together a speed3 kit if you want cheaper. I don't know how the fit on the 2.3 would be for MS3 aftermarket parts (manifold, DP, FMIC) but you could even try those as well.
