its a waste to drop that much $$$ on a 22r. you could do a swap for about that much. you might want to check engbldr.com

 

IIRC the 22r already has a pretty good stroke. Much more and it will need a super/turbocharger because it won't be able to pull enough air in with a cam duration that is good for wheeling.

 

Not only do you need a stroker crank, but custom pistons with a matching wrist pin offset.
If you increased the stroke and did not lower the wrist pin location on the piston, it would hit the head.
Sorry about this news--there is no cheap answer.

The 22R(E) series motor is ALREADY essentially a stroker motor.

 

ok thats good to know, so how much can u bore these and still have reliability, and then why dont someone make a high flow head, how much bigger can the valves go

 

its easy...its called an engine swap...lol
