what’s going on guys, i was just wondering if some of y’all could help me put together a parts list and a good route to take cause i want to move forward with a turbo, i have a 99 prelude with an h22a and i’m thinking maybe 8-10lbs would be good with a stock motor, i’m curretly rebuilding it with new seals but plan on buying turbo parts soon, i was hoping to make like 320-350 whp if that’s reasonable, but i would like to keep AC, don’t care for PowerSteering though
ppreciate the help guys

doesn't matter how much boost you run the weak ringlands will give out or youll end up with a spun bearing

damn it’s like that, i don’t really mind blowing the motor cause i have a spare but what if i use those mahle drop in pistons and replace the pistons rings?

its a gamble. either you get lucky or blow it up. I have a friend that went with the mahle pistons and his lasted about a year. if you don't really get on the pedal youll have a better chance but what fun is that lol. keep an eye out for anyone selling a sleeved block. that will save you a lot of money.

nice flowing manifold / exhaust is key

so how bout this, the spare motor i have is an h22a4 and i took it out my first prelude cause of a spun bearing, as of right now i’m tearing it down and got the block off the head and tearing down the block to see if my crank got effed up, you think it’s better to just rebuild this block or get a new sleeved block? this is all assuming i’m going the route to turbo, cause i might just build this block

elaborate pls, also are you in soflo?

ya i am but i don't have a lude anymore. join the florida prelude page on FB. one of the guys down here has a lude with a setup that is making about 350 whp on a stock h23a


you need a tubular style manifold ram horn, top or bottom mount. no log style manifolds. also 3 inch exhaust

damn forreal, i was hoping to keep at least my ac :/ and any brands in particular?

i think lovefab makes a manifold that's equal length that keeps ac but im not even sure if they are still making anything for h22's. also don't listen to soflakid he drives a Miata.

actually **** allat, i want to take my spare motor and rebuild it H2b with turbo, it seems like buying a new sleeved block would be around the same as shipping mine out to get sleeved, you still think it would be bad to go turbo with stock motor, and yeah i know ppl recommend to just build it fully while it’s out the car but that’s hella money and with buying the h2b kit and a tranny that’s already a lot... so whatchu think? i would like to keep ac with my lude cause it’s my daily and it seems like a pain to build it already in the car

i seen people selling sleeved blocks and already built bottom ends sell for less than actually having it shipped out milled and sleeved. since you have a backup motor you can boost the stock one with a good tune but its a gamble how long itll last. i had ringlands give out on a motor that wasn't even boosted so who really knows with these h22s. and you definitely need ac in florida fok that

where you finding the prices for that cause i’ve been looking all over online for an already sleeved block and the only one i found on ebay is for 1500 OBO, this kinda sucks since i already have a block, i’m really bout to boost on stock

Just spend the money now and build it or buy it man, because if you boost the stock block and you blow it then its just money (down the toilet).

Build/Buy now and for days to come.

alright so just sleeve it or buy a sleeved block, forged pistons and rods, is head work really necessary when boosting? and if so what’s the best route?

I don't know enough to advise on that, maybe someone else can pitch in.

having a built bottom end is enough unless youre doing a crazy +800whp build or something. ive seen built and assembled blocks selling for like $1,800.

alrogh cool, ill just go that route then and if you have any more advice that would be greatly appreciated

Join Florida Preludes and Florida Prelude parts on Facebook. I saw a sleeved block going for around 800 but needed to be rebuilt a few weeks ago. Blake aka 850 fab (in FL) is currently making AC/PS compatible manifolds for H22s and hes been in the prelude game for years.

H2B for preludes really isn't possible. Its not the same as doing it in a civic. KS made a Prelude H2B kit but it didn't really sell many and I don't believe they currently make it anymore. Your best bet is a T2W4 transmission imo


I wouldn't sleeve a H22 for just 350 whp. If your engine has good compression buy quality parts and get a great tune and it should be ok. Yes it could blow up but I would be more worried about tearing up clutches with double the torque. Buying a low mile h23a > sleeving engine for 350. or just buy an S2000 fam

yeah i was thinking of hitting up blake for some work but not until i have everything set... and i wasn’t really gonna do H2B in a prelude lol it was gonna go in a civic also idk man, i really want an s2k but i love my prelude
i also sent an inv for the group and they haven’t accepted me and it’s been a couple days, i’m also part of florida prelude parts

I'm not going to advice on what to do or not do but I know one thing for sure in this game..."If you wanna play you gotta pay"!!

fast, reliable, cheap. you can only pick 2
