also the F22 sleeves are steel so they can handle a lot on stock internals.. check out www.homemadeturbo.com i'm draztik on there. theres a guy with the 90-93 accord with F22 running 15 psi on stock internals which is stronger.. steel or aluminum, think about it, so dont' say you can only go for looks cuz it takes 6000 to get the car fast cuz its an accord. and the F22a1's have 8.8:1CR perfect for boost, another reason why they can boost so high, less chance of detonation with more boost. enough said.
