so... I plan on droping in the LS6 cam and using the STS turbo setup on my 2000 5.3L. I dont know what exact ls6 cam I need or what else I will need to get to do this correctly. HELP please. I know you guys are probably pretty familliar with this. so thanks in advance.
I will be placing this on a desert prerunner chevy, so any tips on a dirty enviroment would be great too!
thank you so much in advance!

did i mention thank you? I appreciate the help so much! so thanks again
just get you a nice valve spring like a set of patriot golds and a set of hardened 7.4 pushrods and slap it in there
ok.. but are there different types of ls6 cams? any patcular year? sorry if I sound dumb... but I am!!! I dont mind spending the money. I just want it done the best i can with the best right parts. reliability is of the utmost importance.
are those pushrods the same size as stock?
thanks man.. im really excited about this since i live right next to Irwindale speedway and the run a 1/8 mile "test n tune" race every Thursday... i wanna put this thing up against some vettes and other wanna be hot rods and at least suprise em! maybe even beat a few!!!
02 up LS6 cam has the bigger lift and duration....
here's a good place to find the cam Scoggin Dickey Parts Center: GM Performance Parts, GM Crate Engines, GM Goodwrench Crate Motors and Performance Crate Engines
and yes the comp 7.4 pushrods are the stock length replacement ones
thanks.... thats exactly what i am looking for! and that should bump up my HP pretty good right? i have a bone stock 2000 5.3L
The LS6 cam is a good boost friendly cam, especially if you are on a budget. You can pick them up regularly for around $125. If you want something more suited for your exact application, you can get a custom grind. They are around $500 though. IMO, the LS6 has been proven to produce good numbers with boost.
As far as pushrods, the 7.4's will work but I believe that you should use 7.425's. The base circle on the LS6 cam is slightly smaller but since our trucks have hydraulic lifters, it is supposed to make up the difference. I've read people have run both lengths and been fine.
You will need to measure for pushrod when using LS6 cam.
The 02' and up does have a smaller base circle.
Cant use off the shelf 7.4's
I would not use the STS turbo kit either.
Trick Performance front mount turbo - FTW
Hey I just got my LS6 cam from there...weird.Quote:

What psi are you wanting to run with this thing? Also how much power are you looking for?
out of curiousity, why would you NOT use the STS turbo?Quote:

I'm not trying to get to crazy as it is important I can run the motor 200 miles in the desert and still get it home!Quote:

ok, so what exactly is the base circle? i see the ls6 cam is .050 smaller. what does that affect and is it a fitment issue?
of course im thinking ill have slop in it with the added clearence... but I really have no idea. I am learning and I am a good / fast learner. so I am confident in jumping into to a cam swap.
I come from Motorcycle engine work on the 4 strokes. I would imagine some similar things apply.
oh yea, i am gonna run it at a local 1/8 mile strip just to show off a little i hope! maybe wax a few imports or magnums!
I'm a huge fan of the rear mount turbos man but it's really not the most logical thing for you being a desert runner. You could get a lot of power and more reliability for the desert out of a front mount. I would say go with a 70mm that way when you out grow 420 rwhp you just have to turn up the boost.Quote:

Yeah, 02 and up Z06 cam is good for boost. So is a Lingenfelter GT2-3. If you run a Z06 cam, you can use yellow Z06 springs. A little cheaper, but gets you the same result.
On a stock motor, 8 psi will be fine.
Cause they suckQuote:

I guess if you like taking it in the rear go with a rear mount turbo ........ just say'n
There is a place for rear mount turbos.
Thats on cars that that is the ONLY place it will fit.
Next to engine and up high is better for many reasons.
Turbo likes to be hot
Exhaust gasses going thru turbo like to be hot
Closer the turbo to engine the better
Gravity feed oil drain from turbo, no pump to go out, or blown seals.
If you're going to be off roading the LAST place I would want my turbo is under the car.
rear low mount turbos have everything you'd want in a good turbo design
going against them.
x2 if you are going to be seeing any type of air time or some what extrem off road or anything where you might scrape ur frame rails that turbo kit will be dead, front mount turbo kit for the win! I also like the GT2-3 cam over the ls6 it should idle "meaner" if you will have some more lope. oh also about the springs might as well go all out if you are going boost get some PRC springs so you never have to worry about valve foatQuote:

ok... so no rear mount turbo. I'm trying to save space up front where the engine cage, shock hoop brace, resivoir...etc. I was thinking the rear mount turbo would be great. what if I plumed it up above the rear frame and fabricated it into the rear bed cage?
so what front mount turbo would be ideal? I'll spend the money if the product is worth it. so I mean whats a good one?
as for springs????? PRC Springs? do you know exactly what size and so forth springs I need? I will get em. I like the whole buy it once approach.
guy... thank you sooo much for all your help... I cant say thank you enough!!

He makes a better low mount set-up too. Puts turbo
near trans instead of under bed.
Front mount puts turbo next to oil filler neck. Not in the way of anything.
nice.... this makes me want to get a turbo on it sooo bad right now!
Trick makes a very good kit from what I hear. You can also PM KBracing96 and get anything you will need from him as well. That way if you wanted to just get a log manifold and do some of the fab work yourself...like crossover, down pipe, all of the cold side piping...instead of buy a whole kit you can go that route.
For your power goals I would say to go with a 70mm turbo. Or you could step up to a 76 and have some room to grow into it.....youre never going to want to stop upping the boost and power.
