Compatability of CTR head with B20- block?
Will there be any issues with teh combustion chamber size on a B20 with a CTR head and tranny? Just an idea mind you...I know that the B20 crank won't be stable enough at high RPM. If I am wrong about that, feel free to inform me though.....

The CTR Head is no different than a b16a2 in reference to it's initial casting.
The differences are in the factory mild porting, camshafts, lma's and valvetrain.
Use a stock B20b/z Headgasket or aftermarket B20b/z Gasket.
The combustion chamber volume is still 42.7cc on all B-series VTEC motors
You have zero issues mating these two together.
Some people recommend getting the combustion chamber resized to match the 84mm bore. I say forget it.
The b20vtec instabilty is mostly a big ******* myth which spawns others to spread propaganda about **** they barely understand. Hence your misinformed idea about crankshaft instability. (I don't know who the hell told you that one.) I have never heard of the crankshaft being unstable. The instabilities usually reside in the factory sleeve strength and side loading the cylinder walls excessively due to the lackluster rod/stroke ratio. But I believe there are variables in the sleeves that make occaisional batches weaker than others.

Hmmm, that makes sense. I just question how well the B20 bottom would hold up to an 8500 RPM shift point. Plus it doesn't have the oil gallies that the R motor's have, does it? I've got a spare R head right now, and toying with the idea of a B20vtec.....but I've never built one. Just don't want to end up destroying a motor.

I'm not sure about the galleys but I hit 8700 all day everyday and I have had zero problems. I do know that the oil squirters that are present on the R motor are missing from all non-vtec motors. With forged internals this is no problem.

how many km's have you put on your b20vtec setup?
