Increaseing displacement ?????

[nonovurbizniz]

You don't really need to increase the displacement of a 2.2.

you can do it buy buying SHORTER rods or a crank with shortened lobes (can't think of what they're called). or bore over..

as far as redline that is more dependent on your valvetrain then your bottom end... theoretically you decrease your motors ability to rev high when you shorten your rods or crank lobes. but this is not always the case.

as far as how much disp. I can't imagine you going over 2.5->2.8

I think that may even be high...

These are VERY advanced questions the kind which you will NOT get a proper answer to on the internet... If your serious about this project I'd start looking for some reputable shops that build honda engines and ask them all these Q's.

good luck
