If it's just a stock rebuild, then no it won't handle any more rpm than stock. If you've got a lightened and balanced lower end and stronger valvesprings along with light retainers, you should be able to bump the limiter up a bit.
so everything stock we could go 7200rpm ? it's just about 500rpm more .... don't seem that much. Or we would have to put spring and retainer in the head ? :Originally posted by WytchDctr
The issue with the redline is the actual speed the piston has to move to make that rpm. 75fps seems to be the do not cross, unless its a race engine, limit. The 2.0 beta's piston will hit that 75fps mark just over 7200rpms. The 1.8s piston speed is lower for a given rpm and I think its limit is just over 8000rpms. Then there is the question of will the valvetrain take it??.. Intertial loads > combustion loads. Id say dont stay on stock redline unless your running a bigger cam matched with a massive intake system.
