Just want to know, i have Dohc-Vtec F20b lying around and i also have an h22a out of the prelude complete head that i could part out aswell... and i just wanted to know what is better for the f20b block, N/A or Boost? I know the F20b comes with stock compression 11.0.1 which is pretty high for boost, but ive also heard that it is takes a better liking to boost than an h22 because of the stronger iron sleeves. So if i just swap out those cams to some turbo cams for some lower compression and throw in some boost, how much psi and hp am i looking at stock? Is this a better idea than running N/A? Please note that $ is an issue i have to work for it, not **** it out lol..bu just looking for the easiest, cheapest and quickest hp gain. Any info is greatly appreciated. Thanks

 

easy quick way to more hp=nitrious

 

and i have seen plenty of high comp. boost'd cars, its all in the tune, good tuner and 11:1 should not be that big a deal

 

Iron sleeves aren't necessarily stronger, but they will accept a forged piston without forging or special piston coatings. If I were to boost one, I would choose the H22 with some mahle pistons. Even with stock compression they can take a decent amount of boost. There is some good info on ************ regarding H22s and boost.
