my buddy took an old integra lx block and put a dohc vtech head on it to throw on about 70 hp is that sort of thing possible for the sohc lude?

not sure how easy it is with the sohc prelude F22 motor. ask around but i'm pretty sure its a lotta werk to attach a H22 head onto that block. the thing with the hybrid for the integra is that when you put a vtec head onto the LS block, you gain massive torque, more torque than the gsr. if you want something comparable to that, you would want to get the prelude Si block (H23) and combine it with a vtec prelude (H22) head. then you get the torque gains in the same way that the vtec LS integra does. no point in just making a hybrid F22 vtec motor since you wont gain any extra torque from it. just swap the entire motor with a H22A.

not worth doing in my opinion. the money you are gonna spend to put a F22B1(vtec accord) head onto your F22A1 block isn't worth the horsepower gains. if you're gonna spend the money for a motor swap or hybrid, you would be best off with getting a H-series motor. definitely more worthwhile in my opinion. actually the entire hybrid idea in my opinion is not worthwhile. you mite as well just swap out yer entire motor. much more dependable and easy to do.

Head swaps might work for a short while, but do a bit of research, and you'll find that it's not the wisest idea. Just swap out the whole engine and/or build it or build the one you have (i.e expensive internal work).
