What's the best tuning

[ozonehostile]

you probably wont need to be bay mounting a turbo unless your putting a massive blower on, which would be a silly idea if your planning to keep it as reliable as possible and use it daily. read some peoples projects on here for different ideas, but one of the more common setups which has proven good results (upto 180ish bhp) is a td04 turbo (which fits in the oem place behind the engine) and hybrid fuel pump. fmic is always a good idea for an upgrade as it actually cools the charge unlike the standard topmount cooler.

Gearbox mounting a turbo also brings alot of new challenges like having to make a unique manifold and down pipe for your setup, which unless your shit hot at tube welding isnt going to be cheap
