haha, mine is ghetto-tuned. I have neither time nor money to get it dyno-tuned. Also, there are no reputable tuners around here anyways.
If you know what you're doing, then custom build your kit. I bought a pre-packaged kit because it helps me learn how turbos work. Now I know, so next time I'm going custom.
H22 is an okay swap, but I wouldn't do it personally. Also, you do NOT want an SH swap because supposedly the ATTS system is a b1tch to wire up. If you keep the D16, then definately go turbo. It's the only way to make decent power.
A turbo would definately be cheaper than a H22 swap. With an H22, you want a good suspension to help you get traction. You need a mount kit also on top of the WHOLE swap itself.
