yeah, that's true, but most people wouldn't even fathom boosting 14 psi on a stock bottom end anyways. i would say it would definitely hold 10 psi very well, which is basically what most people with stock engine stick around anyways..... just my .02, i've never even had a boosted car

 

it is true what they said about b20 sleeves. Pistons and rods are suppose to give first. There are people who are running 15psi+ on stock LS sleeves with no problem. b20 wouldn't last that long.

 

I second that... B20's have weak sleeves.

 

Poooooop!!!!
