before i boost my h22 what all do i need and what all do i need to replace in the motor to safely boost ten to 12 pounds of boost and it be reliable?
everything needs to be replaced, from sleeves, to rods, pistons,rings and wristpin, bearings, oil pump, water pump, remove the balance shaft, valves, valve springs, valve seals, retainers, cams, cam gears, timing belt, feul rail, injectors, fuel pressure regulator, fuel pump, feul lines, intake manifold, exhaust manifold, head gasket, axel seals, rear main and front main seals, oil pressure switch, oil filter, fuel filter, air filter, chipped ecm or stand alone unit, distirbutor, spark plugs, ignition wires, cam seal, oil cooler o ring, throttle body, pcv vlave, you will also need turbo, wastegete, blow off valve, intercooler, intercooler piping, wideband o2, egt gauge, intake manifold gasket, boost gauge, clutch, and machine work. you will have to have your block decked and sleeved, get you crank micropolishe(at the very least) and knifeedged, get the mains honed, then have your head machined for the valves(multi angled valve job), and the ports polished, get the intake manifold polished, then onto assembly(which should be left to the skilled hands of a professional) and then installation and finally tuning.
if at any point you read this and determine that you do not need any of these things then it is time to postpone your build and go and do more research. remember it is all about combination combination combination....
OP--Boucks post is a perfect example on exactly why most good turbo builds on an H22 cost $4-6k at the very least. Often times in the $5-6k. Sometimes, higher.
Turboing our engines is not light task, and takes not only a ****load of money, but research to make sure you're not going to blow your motor on it's first time on the dyno.
Couple things about bouck's comment I would like to have clarified and other points I thought needed to be added:
1) I was told by many prelude owners NOT to knifedge the H22 crank as it serves no actual purpose in the H22 engine
2) He doesnt HAVE to rebuild his whole head (camshafts, cams, pnp) he can do that later but he wont see full turbo yeild. But he should get valves, valvesprings, and retainers with a valvejob as that seems a necessity (but why go half-way? lol)
3) I'm surprised no one asked whats his whp goals are, as psi means nothing if we dont know what turbo he is running (or is looking at running).
4) Stock fuel rail I am told is sufficient to 500hp
5) There are a few other parts on your list he doesnt NEED (like TB and IM) but will definitely help reach a higher whp goal (without knowing goals you just threw everything out there which I can respect and understand).
6) How many miles are on his block? If not many he could go for the Mahle pistons and let us know how those work out for him (so he doesnt have to sleeve).
I see the build Bouck listed as being way more than 6k, that reminds me of another peice of info we dont have... budget.
So we dont have a budget, we dont have a goal, we just have an open-ended question that creates more questions then answers. I would suggest the OP to gather his thoughts and post more info so he could get some good help (Bouck's help was damn good though but it can be taken farther with additional information).
That's a great first post. However, there's something you don't realize. This isn't "Spoon-feed me how to turbo my car." His extremely vague (and noobie) question was answered vaguely on purpose.

^ You are correct, sir. I have probably wasted my time typing all of that but my main concern was the the OP did not consider knife-edging his crank. The rest just sort of came out, lol.
at least 250 horsepower, no budget just the more expensive the more time it'll take, motor has 175000 wasnt going to turbo this exact one for sure may buy another h22a4, and thats y i posted the post im doing research asking around to see wat needs to be done n order for it not to blow...anyway thanks for the list thats wat i was lookin for now with that info is all that stuff first listed still nec.? oh n not sure wat kind of turbo yet prolly a t3 t4 though

Listen here, dip****. Keep your nooblet comments to yourself. No one disrespected you, so there's no cause to be ghey.

Unfortunately for you, the OP, Kronn's answer is 99% of what you will get in forums and he is right in the since that your questions HAVE been asked, many, many times before and if you are a long time member you get tired of answering the same questions over and over again (that's why I'm new here but NOT to prelude forums).
The short story is that ALL of your questions can be answered using your own time and the search function on this website and others.
Also, nothing is engraved in stone so one person might say Darton Sleeves are FTW!!#@! and another person might say GOLDEN EAGLE mutha****a!!@!@ so (dumb example since they are both great companies).
I think the questions you are asking are too general and will not yeild much of the response you are looking for. BUT, if it evident that you HAVE done reseach and you are asking educated (and specific) questions you will likely get a good answer or get pointed in the right direction.
kronn does burn people but it was easy to burn you t jae

IMO
1. 250hp is achievable wo turbo because that is the exact number i am going for. Not only that, approx 1 psi = roughly 10 hp... 12 pounds of boost you will be flying places with other STIs and what not?
2. another h22a4? why... do you like to waste money? at least buy h22a which is jdm AND SLEEVED
3. Sorry man, but you seem like a guy who if had a boosted prelude would kill somebody on the road jk. be safe

You are going to have things go wrong, you will go over budget, you should always have emergency funds on hand.
Don't look to be spoon fed. Boost is an experience. Hopefully you read enough that you don't make the exact same mistake as someone else, not that the same issues won't arise, but, maybe in different ways.
