I posted this same post in the Prelude forum here on HT. My question basically is, which is the best motor to build for forced induction? The H22A4 or the K20A2. This is the situation. I have a Prelude all payed off that I could build or I was thinking that I could build an RSX if I sold the Prelude. Which has the most max potential. What would you do and why?

 

do the prelude. You can get a lot of power out of it. Look at Precisonh23a (i think that is right) power. Plus you have it paid off
