Owning a 1990 2.2i Honda Accord with a F22A3 Engine (European) I was thinking of doing the old Engine swap for a H22 to give me the extra power. Now with all my mods I am upto 165hp/155lb torque.
The compression ratio on the engine is about 8.8:1 and I would like to know how much extra power would I be able to get if it is possible to get the compression to at least 10:1 and ideally up with the Hww of 10.6:1 or even 11:1

How would one go about trying to even get the compression ratio up?

Sorry for the noobie type questions but I dont understand the compression ratio fully yet.
What would others recommend, stay away from upping the compression and just slap the H22 in?

Any and all help would be appreciated

Thank you

Changing compression is done by changing pistons out and/or making the head gasket thicker/thinner (not really the preferred way).

 

I wouldn't go above 10.6:1 compression ratio on pump gas, but England might have higher octane than us so you might be safe with 11:1.

One other way to raise the compression ratio is to shave the head a little, but it's not really a preferred way either.

 

yeah you should be fine as long as you run higher octane gas to prevent detonation

 

What's the standard compression on the F22b1? Is it the same as the F22A3 (8.8:1)? What are the cons of shaving the head to increase compression? Is it the wear and tear on stock internals (pistons, rings and the like)?
