Well what about the viggen turbo set up? I know the N/A has the b234 and the viggen has the b235, but they're both 2.3L...
I guess I dont really know much about viggens (someone please enlighten me!).
I'm just looking to get more power out of my 900 S without having to sell it, haha. The car is kind of a family heirloom, and i like having a project to work on, and I thought a turbo might be fun / a nice challenge
Any other sources of power gain other than air intake and exhaust for the N/A?
