I was wondering a few things about the B20, cus i just see more potential for turboing that over my GSR motor. First off, are the B20 head and LS heads any diffrent, And if I build the head with Crower parts. How far could i rev? Mt plans are to sleeve a B20 block with eagle rods and JE pistons, and put an FMAX kit on it.

So if anyone could just give a turbo newbie some insight i would apreciate it. Or if anyone can convince me to run my GSR oposed to the B20 your opinions are welcome also.

Thanks, Brandon

 

the LS and B20 use the exact same head. you can use all crower non-VTEC parts in the B20 head.

if your bottom end is properly built up to take the extreme high RPM and boost then you shouldent have any problems reving up to 8000-8500rpm with the proper crower dual valve springs and ti-retainers. provided the cams you choose will make good power up that high.......
