I've seen it all from turbo f22, h22a swap, and turbo h22a. Has anyone built there motor straight up for NA. I mean all motor. Running high compression. I am still looking for other ideas. I want to get turbo, but I could get a H22A before turbo anyday. But what would it cost to rebuild for high compression and how much am I looking at. Want to be different. Any help out there??
