LS6 Cam question
LS6 Cam question I'm wanting to do a sleeper build up however on a budget. I like the specs on the Sleeper cam from MTI or the old man from Thunder racing. . .however I have found several used Z06 cams for under $100. So based on financial issues I am opted to go with a Z06 Cam.
Now my question is what will I need to get this installed and working safely?
What type of springs,, pushrods, etc etc etc, yet on a budget btw. I know the cam is good for up to 6600RPMs however I'm leaving it tuned at 6400 presently with my shift points at 6250. (Already have LS1 Edit and that part seems to be my cars ideal run)
Thanks for the help!!
and btw, what type of gains at the track I may see? I figure 10 - 20 from what I've read HP wise on a dyno but to my that doesn't count, rather the track does as the conditions are different. If it'll shave off at least .2 of a second off it's worth it in my opinion. Am I close or what?
Thanks!!

u can do just springs.. but i'd do pushrods just to be safe. this cam preforms well on the street.. but u wont notice much gain at the track i got 3mph and .2 tenths out of the cam alone.
i think u're better off waiting and saving up for the stealth cam u'll be happier w/ it in the long run.. i'm wanting to upgrade cams now :/ after a few months of the ls6 cam the car runs strong but not strong enough

I wouldn't let anyone talk you out of the '02 LS6 cam. It sounds like it fits your goals very well. A friend installed this cam in his '02 SS A4 and put down 352rwhp/343rwtq. This was with the cam, lid, and ported TB only. He later switch to the TR Old Man cam and only picked up a few hp/tq, but many other problems. The car surged, searched for idle, stalled at times, and had terrible valvetrain noise. In my opinion, the slight gains were not worth the additional problems.
I wouldn't use LS6 spings with the LS1 valves though. The LS6 springs were designed for the lightweight LS6 valves. Since LS6 cam makes power to 6500 rpms, I recommend switching to the LS6 valves or 918 valve springs.

The 02- up LS6 springs will work just fine. I have had mine in for over a year and my shift points are 6400 and I have had no problems at all. I recommend changing push rods if you plan to spin it over 6300.

Verdad Gallardo Thanks guys. I probably wouldn't let it rev over 6250 which is my current shift point now.
350 to 375 at the wheels is my goal basically and doing so on a budget. I'm in a way debating on the Z06 cam or going with Crower-motorsports and they have awesome pricing on their cams. Alot cheaper than everyone else by $150+!!
But if I could gain close to 30hp on the wheels with a Z06 cam then that should be enough. But is that with headers, etc or over manifolds? If over manifolds then great.
That would net me around 340 to 350 at the wheels (currently 320) and then later, Long tube headers and that should give me 350 - 360 I would imagine.
Be close enough and a low 12 second car with some good suspension work right?

Thanks man!!
I have the 02 LS6 cam and springs in my 01 Z28. You can click the link to my thread for details on hp gains.

P.S.- I bought a cam install kit from Thunder Racing. It includes all the gaskets you need and a new crank bolt.

A higher stall converter is the single best modification you can make to an A4 car. However, if you still want to keep the stock converter this cam will not present any problems. The torque curve is identical in the low end. This cam doesn't start to make more power than the stock cam until around 4,500. 
i like my ls6 cam.it idles and sounds like stock.it makes descent power and its economical which is rare for our cars.
there are much better cams available but they cost alot more.
with a stall i just added my car runs great with this cam.
ive been using stock PRs and my redline is 6600 and ive had no problems.

When I installed this cam I only did the cam and LS6 springs. While others may prove to be "better" springs to use, there are no problems to be had.
My rev limiter is at 6500, I have no clue where I shift at sometimes because of my tach lag. I've banged it many times yet my stock sized pushrods are just fine.

I used to run an 02 LS6 cam with 02 LS6 springs. It was my first cam and it really pulled hard on the top end compared to the stock LS1 cam. I reused the stock pushrods and spun it to 6500 rpms for almost 7000 miles with no ill effects or problems. With LT's, ORY, CME, ASP, Ported TB, LS6 cam @ a tune I pulled 376rwhp @ 361 rwtq. To get max power out of the cam shift at 6500 with your rev limit at 6600. If you are shifting around 6200 rpms your leaving some power on the table.
