I've had my E30 for a little over 5months now and i've done a whole bunch of maintenance and suspension upgrades but never touched the engine performance wise. I like the M42 so I dont want to swap anything else into it. I was thinking the turbo route. I know this is probably on here a lot but what are some good pointers. Im looking for a direction to point myself in and start laying down some power with this thing. I havent done much research at all with Turbo M42s or making power with M42s in general. Thanks guys
