    so i have a basicly bone stock f20a4 with a whoping 136hp to the wheels...
    (just has a tubilar srs header and a "cold" air intake)

    but ive done some googleing and youtubeing and what i saw was people putting H22a4 pistons and a F22b dohc non vtec head witch would make acording to yt 170bhp but i was wondering if this even real and if it would wotk with the stock ecu or should i invest in a hondata

    anyway i would priciate if people would help me out

    lol made a whopping 136 hp at the crank on its best day in 1993 lol and swapping it to a h22 would be easiest route forget about building the motor its a economy motor meant to run smooth and get good mpgs

    .... when you get into building frankenstein motors it wont be cheap or fun or reliable , and just judging by this post im assuming your car is wide open throttle all the time and CEL on with multiple codes prob missing/unplugged oxygen sensors ersumshit, if cant afford it then just drive it as is and save ... if you wanted a sports car should have bought one instead of a economy family sedan

    no its exualy in really nice shape has only 175xxxkm on it of granny driving even just stock suspension on my prelude V and everything so yeah it was just a question and looking at you i assume youre from america where you can go to the junk and grab a h22 out of a car for 250 here it has already been done for us and we pay 4 grand for a h22 so no idk about you but i font have 4 grand just for the engine that is without the gearbox ecu wireing motormounts axels and all that sweet jazz

    oh luckily prelude and not accord but like I said same note just save your $$$$ , I promise you doing the head conversion is just going to be a pain in the ass and shorten the motors lifespan, and if can then turbocharge it on 5-8lbs on stock motor should put you over the 200whp range

    if they are the same OBD generation you just need the h22 and the ecu , it uses same mounts etc and can reuse your trans + axles
