You are extreamly limited on the d17 I believe speedfos on d-series had the badest d17 around but he is parting it out now.

If you want serious power go with a k swap or a differant car.

If you just want something fun I/H/E and some suspension work will be enough to have some fun when you want.

Yea a few things are interchangeable but not enough to help you in your goals
