I have prc 5.3 heads and a MS3 cam in my car and I might be getting a sts kit, How do you think this will work ? Should a go with a small cam ? Let me know your thoughts. Thanks Steve

I think if you have too much lope you lose boost. So probably a better idea to get a smaller one.

Correct me if I'm wrong.

The ms3 with turbo isn't optimal but it will work. What head chamber cc and
lsa? I ask because some ms3 grinds you could order with differant
lsa's.

I think the compression ratio with the 5.3 heads may not be optimal for getting the most out of the turbo; maybe get a set of stock 6 liter heads?

No way on all accounts, bad cam, bad compression.

Absolutally yes it will work, I am an ase certified engine performance and emissions controlls technician, if you can't get it to work you can email me Skater987415@hotmail.com Just don't abuse it to often be smart and figure out the quarks and It'll be good to you.

Yeah it'll work as long as he doesn't put his foot to the floor.. He's probably more than 10:5:1 cr on that set-up which really isn't very desirable for boosted applications.

PREDATOR-Z

A 12* /13* overlap on a street turbo with 10.5+ compression and stock ringlands. Yeah it will work at maybe 5/6 psi. Hardly worth the $$ involved.

We are talking turbo and not supercharger. Supercharger would be better, but not what I would spend $6+ large on.

If you want more power, I suggest 100 shot nitrous.

my cam is on a 114 and I not sure of the cc on the heads Texas speed said it would bring my comp. to 10.75:1 , Its high for boost but, I thought I would ask to see how you guys think it would work. I know I probably not going to be able to run alot or boost or ill blow some head gaskets. Im doing a trade for a atv I have for one, I being hitting my car with a 200 shot for the passed 2 years. Just looking for a change.

Are you continuing to mod the car that is for sale in your sig? Surely you'll never get your money back out of it with the current mods and the turbo. Perhaps you just need to update your signature.
Sounds like you could change all kinds of parts, on your daily driver, if you choose this path.
As has been stated, not the right combination of parts to support a turbo.

I think you better spray....

If you do want to go FI, I would change cams and heads

if you decide to do the turbo, sell your current heads and get stock 6L heads with the bigger chamber to drop your CR

One guy resently did this, it's not going to get the power you're looking for. With the high compression ratio you are going to have to cut the timing way down. Do an advanced search under the FI section this gets asked there at least once a month. Alot of great info there.

will it bolt up and make a few PSI? yes.

will it be worth the investment for power gained? no.

will it be worth the risk of forcing boost into a high compression motor with hyperutectic pistons? no.

Like Predator said, and he knows what he's talking about, don't do it.

There is a guy on ls1gto.com running an HPE S2 cam with a procharger making about 600 at the wheels and loving it... the cam will work. The heads are a no no... youre looking at about 10.75ish:1 compression i think with thsoe bad boys.

If you decide to do it, id be glad to trade you my 241 heads and some cash for your 5.3's or buy them straight up. The 241 heads have a 68cc chamber giving the lowest compression which makes them more boost friendly, but the 243 will flow a little more air but have higher compression also... but ive seen plenty of ls2 cars run fine on boost

Ok cool, thanks alot for your input, we will see what goes on with the kit and Ill see which way to go . i really want to build a motor so Ill see which way I end up going .

Asmodeus

that's a supercharger, the sts is a turbocharger.. there's a difference.
