135i has direct injection and those motors (like many DI motors with turbo systems) are know to have problems with the DI fuel pumps. Do your homework before you buy a DI turbo, I know a guy with a stock 135i who has had his replaced five times by BMW.

Had similar problems on my Mazdaspeed3 with the DI pump.

Also, the reason they make minimal HP vs torque is that the turbos (again like the Mazdaspeed3) dont breathe well up top as they are rather small. You can of course tune the motor and boost them up a lot to make another 75whp easy with exhaust, but the turbos and fuel pump wont last. Many cars just arent built these days to take that kind of stuff. The Z is pretty reliable for the money.
