So as the title states - i am planning on a STS turbo kit, and i aleady have some bolt-ons. Just trying to plan out a cam to go with this setup.

The mods I will have are as follows:

STS Turbo kit
FAST 78MM intake manifold
42lb (or bigger) injectors
Bigger fuel pump
Pacesetter LTs
Pacesetter ORY
MAF Screen Removed
TB Bypass
Spec Stg3+ Clutch
A meth kit
And a cam that will b used with stock heads.

As you can tell im not looking for crazy power. I'd like to be around 500rwhp and torque similar. This is a weekend streetcar more or less

With that said - any suggestions on a decent Cam? or is a custom cam the only route?

Thanks!

PS: I was tempted to PM Pat G. But before I do I was just curious what other peoples experiences are like. I was thinking maybe an LS6 cam would do the trick from what ive been reading. But I'd love to have that cammed sound with that turbo and not sure that LS6 would do it.

give this # a call, he can hook you up with a turbo cam.

Ask for Garth

he got about 550rwhp on a t67 STS ,stock LSmotor, turbo cam/ intercooled & 100oct.fuel

You should ditch the long tube headers for some factory manifolds, unless you want boost to start a 4000rpms.

EPP's forced induction cam. Hands down!

Agree with above. Thats the cam I want for mine.

really?? i thought it wouldn't matter since its exhaust side

With long tubes there is a lot more volume inside, witch in-turn takes longer to compress and since there is a lot more surface area due to 8 separate pipes( one for every cylinder) you loose heat quicker. You want to run stock manifolds since 1) they are made of cast iron and hold heat better 2) there is less volume in each manifold vs. long tubes helping to minimize lag.

You want to keep the most heat in all the way to the turbo via exhaust wrap and try to use 2.5 inch piping to the turbo.

I am still running my long tubes though, but my piping is 2.5 inch and is wraped in exhaust wrap and I bought a .81 housing for my 76mm. I start to build boost by 3500 and hit full boost (10lbs) by 4500, leaving only 1500rpms of monster power. You can drop the lag about a 1000rpms by switching to manifolds. I am planning a front mount due to the lag issue, just want more instant power. The lag is good sometimes due to street tires breaking loose so easy as soon as I hit second gear.

It is possible to break boost it and get full boost by 3500rpms in second at 40mph though.

doh, that sucks lol. yea ill see wat i can do about that. i still have the stock shorties and catted y. which is fine since we have emissions in CT that arent laughable. i just hope that with stock manifolds i can still hit the number id like. being nicer to the ozone is nice too lol

Patrick G is a sponsor up here and I have gotten a cam from him for my setup, and so far I love it. I however have not had time to go to a dyno to see #'s

I would go to Patrick G

when I had the sts set-up I made 55X rwhp and 58x trq.

I was running 10 psi,meth,FMIC, and a ls6 cam. ran it hard for 15-20k sold the kit and the cars under the knife for a front mount kit.

ls6 cam= 65 bucks

when the car first dynoed it had no cats and stock exhaust all the way back. stock heads (just springs/pushrods) stock tb,and ls6 manifold.

but yeah it didn't have any real "cam" idle. which was fine, nice and quite till that ****** spooled....

thanks for the info everyone! yea im thinkin ill do the ls6 just to be more cost effective. if i dont like it ill most definitely hit up pat g. as for the headers and ypipe.. idk what ill do with that - its gonna be a pain getting those LTs back out lol.

u think its worth heat wrapping the the LTs and the entire exhaust as best as possible and run it that way? - hoping for the best and expecting the worst? lol. a little bit of lag isnt gonna make me mad lol

You can and that will be the best you can do without swaping out the headers. You should use the paint that seals the wrap as well. Paint the all the pipe, wrap it tight by getting it wet. Start it let the water dry up, then paint all the wrap. You can paint the exhaust housing of the turbo with the paint too.

I doubt you would be able to wrap the long tubes properly without removing them. On a street car this horse has been beaten to death. Swap out the LT's for the manifolds, you will be much happier to get it out of the way now, then doing it later. Wrap the exhaust at the same time, and don't look back....Until you will want more then 500 rwhp...

Alright cool - i just want to be sure with stock manifolds (keep in mind its a 99), that i will be able to be around 500rwhp lol. if thats a fact, consider me sold lol

thanks again for the input - this is helping me big time

Spend some money on a good fuel system, don't skimp here, and the header wrap, with good tuning, you should be able to reach your goal. A set of 317 heads to drop the compression, will allow more boost, and make tuning a little friendlier.

needaz28

iTrader: (15)

yeah stock manifolds all the way. later on I took the stock pipies off and put mac 2.5 ss from manifold to catback.

take the headers off sell them and use that for a meth kit, or buy the 317 heads I'm selling

sujomatt

iTrader: (7)

hey needaz, pming u on that . also i was curious if u just use thicker head gaskets would that do the compression trick? lol

also, if i grab those heads - do i really need the cam swapped then??

sujomatt

iTrader: (7)

Oh and by the way, anyone have suggestions as to where i can find an ls6 cam??

needaz28

iTrader: (15)

I would still run the ls6 cam. I plan on putting on in the lq4. :shrug:
