Are there any ways to make a b20b block with b16 head a high revving motor? Such as aftermarket rods, crankshaft, pistons, sleeving? Also when people mate the b16 head with the b20 block, do they get the head machined to match the size of the block?

 

Basically the rotating assembly was never ment to be revved high. It has high ammouts of piston to wall friction. If you want to rev high you want forged rods and pistons. A crank may not be necessary depending on how high you want to wind it out. You will also want to have the whole rotating assembly balanced and blueprinted to help. Another concideration is the stress on the sleeves. You should look at block posting or maybe even sleeving. B20's werent designed to rev high so its going to take some work but it can be done.

yup

With new bearings, forged pistons and rods, block can easily take 9grand. That is good enough for me. I asked this same quesiton everywhere as well and it is reliable. Now you still need to work on your head, don't go above 8 without a good valvetrain and cams that can make power that high. Also tune tune and tune
