Have any of you heard or experinced with boring out a 2.2 to a 2.5? Also who makes pistons this size besides JE? Thanks

 

You can go out to 2.6 if you really want.

Any custom piston manufacturer can do it.

BTW, you'll need to sleeve the block first.

 

I heard something funny about the H22 block, That you couldnt sleeve it?? I was just curious if it was true

 

You can sleeve it, actually you have to if you put forged pistons in it. The stock cylinders are either made of or coated with nikasil (sp?) to extend life.

Yes thats what I heard. I was planing on sleeving it anyways. Any one know of any good hp #'s with NA 2.5's or 2.6 H22's? With headwork, cams etc, etc.

 

If you punch it out to 2.5 or 2.6, I don't see why you couldn't pull 250+ WHP from it N/A.

Hell Steph is getting 700+ from his turbo'd H22 punched out.

 

u'll get a hella alot more torque after that...will boring this out change the rod/stroke ratio?

 

You're best bet is to bored it put to the max specs which is 89mm, just remember what type of fuel your going to be playing with rod ratio could stay stock unless you get a stroker kit....rods, crank and piston has to be changed.

 

L'Natural's H22 crx is 2.5L now.....check out their site.........

A friend of mine has a 2.6 h22a in a 92 accord, R & D did the assembly, but before he got to tune it or run it, it blew up, twice. Not that the stroking is a bad idea, he belives it was the way the motor was assembled. He has a 93 H22a block (which is solid deck so its a little stronger), headwork, big cams (web) and all the damn bolt on's you can think of. Before the stroke he was running 14.1 at 3300 ft above sea level. So we are all eagerly awaiting the re-assembly of the 2.6, which he is building now. If you want to pick his brain about the setup, go to his teams website www.collectiveracing.net and register on the web board (it just recently crashed so there arent many posts in there right now) he's always happy to answer questions. Oh and look for his car in the Dec. SCC.

 

How much extra would this cost to do? The boring, etc.
