wtf is cylinder wall float???

Oh and the amount of boost isn't whats gonna hurt anything...concentrate on the amount of power. 15psi on a 14b isn't the same as 15psi on a sc61

Re: turbo or nas on a stock b18a motor

sohc mshue has it right...

You mean cylinder wall "flex"... Valves can float, cylinder walls can flex.

If you run your ign. timing too far advanced you can cause the cylinder walls to flex which can blow head gaskets or crack sleeves aswell as cause a dangerously high egt...
