To solve your problem just buy a Lude & you'll already have a H22 then you can boost or just build for N/A..
Another thing a GSR is fun as is to drive, so having that motor built it'll
run.
I have a GSR & wouldn't waste my money dropping my B18C1 for a H22.
If I had the $$$ for a K motor it'll be nothing less than a K20-R 220 hp stock. Yess Sirrr!! Holla
