Boosting my LS
So i've got 165k on my stock motor right now. i realize boosting that is asking for trouble. What are some vital internals that I should be replacing/upgrading to boost this engine? Not trying to get maximum HP here, would just like a little more power so my car isn't so pussified...^_^

Re: Boosting my LS (v-tecgoswahn)
Why are you guys saying he should rebuild with new bearings/rings/etc? Mileage is certainly not a good determining factor of engine reliability/performance.
He could have 10K miles or 1 million miles. If his compression and leakdown numbers are good, then his motor is just like new.
To the original poster, I wouldn't spend money rebuilding/replacing anything until I knew for sure it had to be done. Go to a compression and leakdown test and determine the condition of your motor first.
From there, you can decide what you want to do. Don't be scared and automatically think that a turbo will make your car unreliable. Tuning is key, and you do it well, it will be just as reliable as your stock car.

Re: Boosting my LS (Wayne_Curr)
sorry wayne dont mean to steal ur thread but i figured it pointless to start a new one for this. so i have 91 rs with 184 on the clock. If I went and did a leakdown and compression test and got back good numbers. I could boost it and not worry about blowin it up. I dont really want the motor swap trouble, and i still want the b18 torque.
how much psi is so?? thanks

If your numbers are good, then your motor is good. It is holding compression.
Do your test, and see what you get.

couldnt have said it better. and that is true tune your car. You can have a fat *** turbo setup but if its not tuned properly you just spent X amount of dollars for nothing.

Re: Boosting my LS (db8xc1x39)
while compression and leakdown tests really do rule, keep in mind that there are some things that those tests won't tell you, like condition of your bearings, the condition of your oil pump, and other important things. i'm not saying that a high-mileage engine can't hack it, i'm just saying good numbers doesn't mean it's perfect.
that said, you should keep in mind that even an engine without really good numbers can be turbocharged and be reliable. those numbers simply indicate that the seal inside the cylinder is good. while this may affect the performance of the engine, it won't really affect the reliability. tuning has a lot more to do with reliability than a leak-down test result. so you lose 20whp from having a beaten motor. who cares? you're turbocharging it. you'll make a lot more power spending that $500-$1000 you would have spent rebuilding on buying a better turbocharger (did i mention you had BETTER NOT be buying a T3/T4 hybrid, mister?) or on better tuning, or on something else more important. okay, so it consumes oil. if you're okay with blowing a little smoke and topping off the oil every so often, go for it anyways.
