LS1 internals under boost - reliability ? Hi,
I'm totally new to this forum. I'm thinking about getting a C5 Corvette now that the prices have dropped to a reasonable level (its ride comfort will be like a Lexus compared to my RX-7, and hopefully with some boost it'll be as quick) - my main concern is that if I get the Corvette and put some reasonable boost into it (7 psi twin-intercooled supercharger), how strong are the stock internals? I know it wasn't built for forced induction, but I also know that Corvettes are built to last, they're not just some slapped together econo-car for revenue.
What are your experiences?
Compared to tb/intake/exhaust/h-pipe/header/408ci shortblock/ported head with cams (thinking SLP's setup), what are the gains?
Any information would be welcome, thanks in advance.

i hear your good for about 8-10 max boost before your internals start getting dangerous.
if you get a new motor, make sure you get specific pistons for boost, and you should have no problem running 15-25 lbs.

stock rods...who knows...mine are at the 650ish level and no probs...pistons...they hate detonation and can'ttakevery much at all. Get better pistons...while you are at it upgrade the rod bolts...use some GM MLS gaskets and you should be good to go. I would also recommend arp head studs. Most importantly, you will need to upgrade your fuel system.
