h22's are not ideal for turbo if you havent already found out. i would suggest a b18c with turbo or go N/a h22 or suprcharge it on low boost. do a seach on this. "h22 turbo"

 

Well.. Im going to try it. H22's are inexpensive in comparison to a gsr engine.
I thought about just doing ls turbo which is best bang for buck but i would miss vtec. I'm doing some research on boosting on h22's with stock internals.
I know there are horor stories about broken ringlands and so on but I would stay
within a "safe" range for psi. Its just a matter of defining what that safe range is.
I have heard 5-8 psi is safe with the drag kit which is what im looking at.

If there are people out there that would question this please by all means
post. Im very interested in hearing your feedback, reasons, technical explanations,
etc.

I won't question it, but I'll add to it. On the H/F-series blocks, the pistons are a softer material than the B-series pistons and the cylinder walls have an FRM lining, which does not work well with forged pistons (thus quite a few seized H/F-series blocks because they aren't aren't sleeved with iron sleeves). The H/F-series motors can take different types of pressure, such as NOS, as the bottom end is built well to handle it. But with boost from a turbo, it puts too much on the soft pistons, causing them to fail easier.

Moderate boost on any motor, with good tuning and control of the boost pressure, will run w/out any problems.

As for in a DA Integra, not enough room in the engine bay (very similar to an EF chassis). When you put an EF/DA engine bay next to an EG/DC/EK engine bay, you'll see that the width apart from shock tower to shock tower is almost the same (maybe off by an inch or so) but the clearance from firewall to rad core support is much less on the EF/DA chassis. Also, the framerail on the EF/DA chassis hangs much lower, giving you clearance issues with the crank pulley and/or the transmission, so cutting of the frame will be required regardless since there's simply not enough room. We've already put the H22 motor into all sorts of different Honda chassis' to see how much room there is and what there is to work with. It's possible, but not feasible, to be putting it into that chassis..... for now at least.

 

I've seen a few tegs with h22's in em but if you wanna go turbo I would say avoid the h22 and go with a H23 bore it to a 2.6 nice low compression and then turbo it just make sure to build the block to hold the boost and get a good wastegate one of the biggest flaws in most turbo setups I see is a shitty wastegate that then slips and pop say time for new motor. Only go boost if you have enough spare money laying around that if it pops you can replace it all.

 

we run 7 psi daily on a totally stock JDM H22 & 9-10 psi for the track..

we have 550's, AEM EMS with an AEM Wideband O2 as well which makes sure we never detonate...no piggy back or fmu bs

of course Dennis my bro tuned it with a good air fuel ratio around 11.0 to 11.9
