GEN2 LS

iTrader: (3)

I have a ls block that has 185,000 miles on it, I have a turbo kit, and was planning on just going LS-T but picked up a GSR head for cheap, so would my car be fine running 8-10lbs on stock internals revving to say 8,000rpm. I would at least replace the headgasket with a thicker one and get some head studs and rod bolts and rod bearings, timing belt, gsr water pump and oil pump etc. only looking for 300whp, and I know that the rod bolts are the weak point on LS motors not really the rods but with 185,000 miles i'm concerned about the rods and pistons and rings just a tad bit.

if your going to do all that work why dont you just get a set of aftermarket pistons and rods?

i boosted my stock LS motor with over 250K and i have no problems. no oil burning just throw the head on there with a stock HG and call it a day

because I can do all the work I listed above in a weekend, if I got pistons and rods that would require me to have a send the motor off to get the cylinders honed, and I can't afford downtime the car is my daily driver.

if you change the rod bolts your going to have to machine hone the rods big end after the instalation the tend to get distorted and size your bearing acordingly i would just leave the stock bolts if your on a budget

high RPMS are what kill LS rod bolts not HP so by staying around stock rpms or like your aid 8,000 you will be just fine
