boosting a 347(newbie)
the reason im posting this thread is because i have a few questions about boost as i am still a newb.
1) how well does the stock crank do on boosted motors? I plan on upgrading rods and bolts...
2) im currently running prc 5.3 heads, i was told i should switch heads but im not sure what to replace them with? everyone says the 5.3's increase compression so thats pointless for a boosted motor...
3) will my bbk intake manifold work with a boosted motor, because i also plan on spraying my nitrous with boost. nothin insane maybe a 100shot at most....
4)looking into sts kits, i was told i need to do something about the oil system what exactly does that mean? as well as running an intercooler, is there anyone that makes intercoolers for a rear mount?
all in all i should be able to be finished with my build at the end of this up coming summer, hopefully i can get some videos up and pictures of the build will its in process

Not really an issue unless you are going for huge numbers....

Yea 5.3s will up the CR over stockers, 317s will drop it. Course, that being said, you can always just change pistons for the right CR since you are building it up anyway...

If you blow the intake up you have other issues...

Dont know enough about STS stuff to answer this one...

With an STS kit, because the turbo is so far back you need a pump to get the oil to the turbo and another pump(i believe) to get the drain to work.

Don't run cats with a turbo mounted behind them, as cats like to spit out their guts from time to time, and these pieces will ruin a turbo. I've personally seen it happen.
The STS oil return system leaves a lot to be desired. Unless they have changed it, it runs back into the passenger valvecover. The connection they used has a habit of coming apart, which can cause oil to pour all over that side of the engine.
If you are going to run a turbo system, Josh at Kentucky Turbo is who I would go with. I don't know how easy they are to install, but he will be there for you if you need help.
Will 317's fit on a stock LS1? Yes. Bob
this is 98Z28CobraKiller little rear-mount turbo... https://ls1tech.com/forums/12476516-post75.html

does anyone know anything about fabbing on the kentucky standard kit, i am currently NOT running a/c or a heater core....
just save money for a proper turbo system, it will be cheaper for you then buying an sts system, installing it, being unhappy with it and buying another system.
if money is a big issue, i would go with a procharger, you will be much happier with it then the sts system.
as far as the heads go, you need to get as big of a combustion chamber as possible. a 72cc 317 head would be the best bang for the buck. you can get a set for 150 bucks
you want a big combustion chamber because it will be less prone to preignite fuel then the same motor with the same CR but with different piston (to compensate for the decrease in the combustion chamber cc's)

it just seems like front mounts/superchargers, are really packed and i wouldnt mind having an sts that way it will be easier for me to work on the motor if the time comes...
