LS bottoms hold up great with boost. How are they weak???GSR Bottom End and B16 head = a poor man's type-r if I recall correctly. Pretty decent combo. LSVtec is not nearly as reliable as people think (LS bottom ends are notoriously weak-walled. Need to sleeve them if you want to make high power). I had an Turbo LS Teg, and had to step the boost down from 10psi to 6psi, and the new owner STILL blew it up.
Yeah I thought as long as you didn't rev em too high it was fine with boost..LS bottoms hold up great with boost. How are they weak???
