Would the h22a be an engine worth fully building up and turbocharging? How much psi can a stock h22a block push? How much would i be looking at to fully build and turbocharge it?

 

I can tell you a few things.

1. Not alot of people go the h22 route for a few main reasons.
2. PSI is arbitrary and is wholly dependant on other factors.
3. You have A LOT of learning to do.
4. How much things cost depends on who you know, and who will be doing most of the work.

Take a bit of time to learn a few things, it'll go a long way in the future.

 

i have one and love it. this should be all the inspiration you need.

 

word, i've seen that video. that del sol stomps that gallardo
why dont many people go h22?

 

The block has FRP sleeves so it's not advised to throw boost on that motor without sleeving. There are special pistions you can buy though. The low end torque while still having a high revving motor is great, I had a H23A in my 93 Si hatch. There are many options to have a "big block" bottom end. It will have more displacement than any other 4 cylinder honda motor you could stuff in there.

 

It's a buttload of work to go H22. It's worth it in my eyes though, it's unique, and teaches you alot about making parts, such as axles. Also teaches you tons about wiring and soldering. Secondary butterflys ftw!

 

Thats what i want to go for was unique, something origin that not many people have. I got an offer on a h22 out of a 2000 prelude with the lsd tranny for $500. The guy said it only has 84,000miles on it. I plan on swaping it into my EF in the future after i build it up. but thanks for the info guys

 

Get it sleeved. Those FRM sleeves are poopy.

 

Buy that like yesterday. that is a fking steal. even if u dont go that route u can resell it.

it is alot of work for an h22 but i love mine.

 

From someone that knows a tiny bit bout H EF's:

FRM cylinders is what all H's have. To run a forged piston successfully without issues or concern it's best to get the block sleeved. Mahle gold series FRM forged pistons (The only FRM forged piston available for the H) haven't been really 100% guarantee every time installed to be able to do the job. The stock factory H piston ringlands is whats the weak point. For turbo on stock internal H I would recommend safely 6-9 psi on a T3/T4e snail 57 trim seems to be a good stock internal low psi snail for the H. It's a must to have a good tuner or engine wont last long and ringlands will break or worse.

But if you have a good budget, Sleeve the block, wiseco pistons 9-1, Eagle Rods, ACL or Honda bearings, Balanced and Blueprinted I would say pretty darn crucial. SS valves, 3-5 angle valve job, a good PnP job is a good investment for power. Get the stock valve springs checked out for consistancy far as being good. H transmissions are good up to 550-600 whp. But that is a whole different topic.
