My buddy just bought an ap2 and after driving it, i can honestly say the AP2 handles significantly better, it feels alot more planted and rigid. The AP2 has potential for boost as well because it runs lower compression, but hardcore f20s are awesome if you have the flow to invest in an aggressive head, high comp pistons, and ITBs. But you are right, the 22 does have a better powerband and you’re also right the 800 extra rpms meaning nothing considering all the power for the ap1 is already gone past 8000.
edit: oh, if you’re looking for AP2s, they’re quite easy to find in the states for that price. Higher mileage ones can be found for as low as 10gs. My friend’s came with Tein flex’s. J’s racing header and an exhaust and he paid less than 15, sub 100k too.
