hey man, i would go with the type r engine, but you should get the ITR instead of the CTR. the extra displacement will be a big benefit, and should be about the same price as the ITR engine. do you want to drag mostly or are you into the turns? if you like autox or road course i wouldnt recommend the h22, just for weight distrubution purposes. if you want a drag car then the h22 would be an ok choice, but i would still get the bseries. it will fit better. the angle of the axles with h22/civic is all wrong, making them prone to breaking. and the bseries will be easier to mod and less expensive as the parts are generally less expensive. give us some insight as to what you wanna do with the car though.
