Yo! FI H22'er in here please!
Please no negative comment. Here is the story. Let's say I have almost 3 g's to spend on a 93 prelude h22a. I want about 350 to 370 Hp, and here's what I have available for the FI setup right now: s200b w/ p72 ecu, external aftermarket coil, fireball ignition system, and new o.e.m radiatior. To reach the 350 or 370 barrier, will it be possible to just spend the money on Aftermarket rods and piston without the high boost sleeves + blue print, balance, knife edge, etc....? I know doing it right cost a furtune than what I have right now to spend but I'm not looking for mad horsepower. I know I'll replace all the require gasket and sealant and all. Opinions please!

I've never worked with H22's before but I am pretty sure that you can't use aftermarket pistons without resleeving the block. The stock sleeves have some sort of fiber in them and are not compatible with forged pistons. If I am wrong am sure someone will correct me.

$3,000 hmmmm
Sleeve the block - precisionh23a does it for $1000 + shipping(100-150)
Buy some Eagle Rods(299.00 shipped in sponsor place)
Buy some pistons - whatever kind
With the rest(maybe about a grand) - buy a nice turbo and intercooler.......then you'll need - some piping, wastegate, manifold, bov, misc things........but its a GREAT start........trust me.........if you get it sleeved correctly - the motor can handle atleast 40psi..........go to erlperformance.com - thats a place here in Indiana that sleeves blocks(1400) but they DO EVERYTHING........heat treating like 5 times......
They did Joe Demarees car - fastest 4cyl on pump gass 8.6x ET - I go to joes shop every now and then - he said HIS block handled around 54psi(on accident).......but nothing happened. I say good ****.

There're people on here that made 400+whp on the H22 stock block. So, I'll go out on a limp and say you'll be ok for 300whp on the stock h22 shortblock. As far as $3K go, I think that's enough for a decent turbo kit. just to make sure you have bigger injectors, at least a walboro 255 fuel pump, FPR. Good luck.

Re: Yo! FI H22'er in here please! (Turbo9Nut)
Turbo9Nut is correct, just get a pump, injectors and a good tune. You can do 300whp stock block and if you dont abuse it every single time you pull it out of the drive way then it will last you a long time. Make sure you run good gas though.
You can do it on a bolt-on drag kit, 10psi+dsm injectors and neptune/hondata...
Why spend the 3000$ on a bottom end to make 300whp when you can do it stock block? Great avatar heh..

300+ hp is well in limits for a stock h22. I've been running this in my stock h22 for a while now and have not had any problems. But spent well over 3K. Just a (good) tune will cost you a significant amount.

Re: (notanotherSC61)
Swap an F block for the H and bolt the H22 head onto it so now you have longer stroke and Iron Sleeves instead of the FRM metal sheit. F block Can take more psi.
My bod did this, screen name sam1am26 I think. He spun a bearing but the motor pulled strong before his mishap.
Lots of info on this frankenstein motor in the Prelude forum.

Re: Yo! FI H22'er in here please! (btrim23)
You cannot run forged pistons in a stock H series cylinder wall due to the nikasil/FRM liner. Now mahle has a piston out that's compatible with the walls as long as you use OEM rings... but I have zero experience with them. Jdogg has used them before but I believe there was a problem with the cut of the valve reliefs and what not.
There have been guys that have pushed 500whp out of a stock block H22a but keep in mind these guys (TylerH and One-Fab) were just seeing how much they could get out of the engine since they had a full build in the works.
Personally, I would not exceed 8-10psi on the street with a bone stock daily driven H series engine. Depending on the trim sizes of the turbo, you should be able to get close to 300whp on this boost level. There have been a lot of guys that have broken their ringlands but then again about 90% of those guys skimped out on fuel and engine management.
$3,000 is really cutting it close in my opinion. If you do want to put out mid 300whp what I might suggest is get your turbo kit installed and have the engine tuned for about 7-8psi. Enjoy it for a while and save your money until you have enough for a rebuild. Trust me, you may start off with a budget of $3k but I have not done a single 'build' to where no changes were made. You always end up spending more than originally planned.

First of all, thanks to everyone that reply.
Second of all, in my opinion as I remember correctly. There have been a few guys in here running aftermarket rods and piston in a b series that have reach the potential HP without sleeving. I don't know how they do it but they have their proof. So I'm just curious if it's possible to do that in a H series motor without sleeving( Just the piston and rod). And of course there's going to be the upgrade of fuel pump, regulator, injectors, and etc that needs to support the number. Thanks.

Re: (btrim23)
Keep in mind that the h & b series motors are completely different and you cannot compare them both. Like mentioned earlier , the h22 is lined with a frm material in the sleeves and cannot accept an after market piston without being sleeved. spend your money on a good turbo setup and boost conservative (6-8 psi) if you dont have money for a fully built block . There are companys that claim that they have come up with a piston that will work with the stock h series block , but no one till this day have had any success.

im going to boost my h22 as well and ive been doing my homework...so here is what ive found. there is a company named Mahle that makes a piston that will work with the stock sleeves. If you are on a budget like i am go to turbocalculator.com. they sell referbed turbos. you can make your own turbo kit. it has turbo, turbo manifold, wastgate, bov, and intercooler. you can get all that for about 1400 - 1600 depending what you choose. the kit does not include piping so ur on ur own with that. so ur at 1400 - 1600 add 300 for the piping kit then you will need injectors 380, fuel pump (walbro 255) 150, a good tune and ull be good. so for about 2200 uve got a good set up(minus tune). if you wanted it would be a good idea to get some arp head studs and a thinner head gasket (raise ur compression) and then that motor will be good for 260-270 @9psi. that will be a safe limit of the motor.
if you have the money to fix the motor if you break something then go for ur 300whp goal!!! good luck on ur build
did i forget anything?

Thanks, I haven't heard any H series in here using the Mahle piston but hopefully it's a quality wise piston. Other than that, I wonder if I can boost higher with the aftermarket Mahle piston and aftermarket rod like Crower? Thanks. good luck to yours.

Re: (97turbols)
mahle doesnt work. No one has got these pistons to work on a h22 , plus people have had issues with rods not fitting. I know it's diffidicult , but there is no cheap route for h22's. I'm in the same boat as you , just boost conservative like 5-6psi daily and maybe have a dual stage mbc to switch to higher boost setting on race days (10-11 psi) . Save your loot and build a bullet proof block , it will run around $2500-$3000.

they only thing that worried me about your comments was the "raise up your compression"... thats defenetly not what you want to do on an h22 in my opinion... there comp ratios are nuts as it is... thats why its so hard to run alot of boost with them... ive heard it bettter to get a thicker headgasket to drop the comp ratio a lil...
