You need to do a lot of research.

The easiest thing to do is to swap in a turbo motor of the same series.

You don't have to change the whole drivetrain, but its a very very very very very very good thing to do.

If you search around for turbo swap its been covered many times.


As far as turboing your n/a, everything has to be custom fabricated. If you have the skills and the knowhow it may be a good idea, if you don't then stick to a turbo swap.

Just take a look at the 2nd gen FAQ sticky. Since this question is asked 1.7 million times a day, it is well covered in the FAQ.

The turbo transmission has a large inspection plate on the bottom. The NA transmission doesn't and just has a drain plug.
