h23+h22 head?
ya from what i know if im thinking of turboing down the line, and i mean downnnn the line, it would require a stronger bottom end, someone on honda-tech told me all about that a while ago, but im not sure what kind of high end power i could get w/o using an h22 head... its kind of unclear what the h23 has for potential, and there arent too many examples of h23 power around either.
i just got my prelude.. i have been doing alot of research on the h23/h22 frankinstein motor. so i have been interested in doing it myself. cause i ahve not seen any numbers on what it can do. i am the type of guy that wants something different in my cars. hopefully i can get the car fixed.. and the motor put together so i can get some numbers and show people. i do have interests in boosting. but i am going to build up the motor as much as i can. then i am going to dyno.. then maybe down the road a boost. i will keep you all informed and take pics.

i think you mean i might as well swap to h22 for boosting instead of boosting 23 or boosting hybrid. idk ill send you my dyno graph, i kinda like the way its distributed... very unhonda like, which, i will admit to people, sometimes i say vw's fit my personality b etter, i like low end/midrange tq to some degree(not to a domestic degree) but not sacrificing too muchpower anywhere else. the dyno really shows how those 160ft lbs at the wheels are on tape from alittle over 3 grand onwards. if the h22 can do it the same way(which is possible, but no1 seems to give me a straight answer)than maybe youre right.
i just feel a bit attahed to the motor and to play off of what i have instead would be fun, which realisticily i cant see myself going past a simple, low end favoring small turbo spooling up w/ minimal lag until im outta college, that is if i enact any of these plans before college.
btw, do you think a venom intake manifold brand new for my car is a good buy at 200$? its in perfect shape, guy bought it for his h22 but it was mislabeled.
well think of it this way - it's like being able to tune low-end and top-end seperately, because you have more airflow available at the top with vtec. it just seems like that would be more important when you're boosting. you have the small cam lobes for low-end smoothness and fuel-economy, and the big-ass vtec cam lobes for that top-end rush.
and for the record, i know very little about boost. Das Schmoo is the one you want to talk to. he's been running a boosted GSR for quite a while.

my friend tried this swap,... keyword tried. yes the head will bolt right on the h23 block. if only it was that simple. the pistons will come up and hit. he had it at a local machine shop and after much money and time was invested, he ended up tearing it all back down and selling the parts on ebay. i know your trying to get out cheap with something big, but really to do this the right way, you would have to buy all new parts for the block. im not sure if its as simple as shaving the pistons, but i guess you could try that. either way you would have to take the block completely apart. not worth it man. just build a h22. and spray or something. youll have much more relibility with the motor. plus, if you keep stock internals with that swap, the bottom wont take the 7500 rpm that the head will. so unless you get a vtec controller, and get it tuned, youll have vtec for like 1000 rpms. seems pointless
oh no this wouldnt be a cheap alternative, lol i know that. just trying to develop my long term plans. a shop in NH told me they have done it before(ive only seen one example, didnt get to talk to the guy) but they claim they know all about it and can do it confidently. I just want to know whether it really performs any better than the h22.
i am almost possitive that it is a direct bolt on the only thing ull need is new motor mounts....i know this because H22 H23 r basically same motor just ones V-tech the other isnt and an H22 will bolt on just needs different motor mounts hope it helps u
