Hey guys new the the vette game. Just picked up a 2002 z06 with cam(don't know the specs which sucks) 243 ported and polished heads upgraded valve train-kooks long tubes-unkown xpipe no cats-broke stingers-vararam air box-think that's it for the motor. Wanted to do new heads intake maybe throttle body and maybe new cam that goes with the right heads. Just not sure what's a good combo and if I'm gonna need fuel components or dif oil pump. Just wanna make sure I don't buy the wrong stuff or stuff I don't need lol. Thanks in advance.

Broke Stingers?
Gotta admit it'd be weird not knowing the specs on a cam in a car I own.
Welcome... all I have to offer.

1- First figure out your budget?

2- Multiply by 3.

3- Then contact-

Tony mamo
Martin smallwood or
Brian tooley to get an amazing setup.

Meant Borla stingers lol
Yea most likey gonna get a new one. It's pretty aggressive sounds great but def want to know all the specs of my car.

OneEvlZ

Yea I heard Brian tooley is the man!

Figure out your goals for the Z first and then work backwards. Why are you already changing parts? Not enough power? Have you dynoed it yet?

OneEvlZ

It dynoed at 440rwhp and 404 torque. Just always want more power lol. Well my head gaskets are leaking so gonna have to change he them out so might as well do heads of I'm down there. Unless I don't need to ya kno. Just learning about these z's

Unless you are going for a max effort build, its best to leave the heads alone. They are already ported and polished and it doesn't get much better(if its a quality port job) for a stock cubed motor, especially for the cost.

New heads are really expensive for little gain over the 243's especially ported ones. Just something to think about.

Of course this is just in my opinion.

Unless you don't like it's street manners I'd leave it alone and drive it. You aren't going to squeeze much more, if even anything, than what you have out of a naturally aspirated LS6.

If you do want a lot more power then I'd go the supercharger route.

OneEvlZ

Thanks guys appreciate all the info. Yea I read with that block N/a u can't squeeze much More Hp out of it and most do either bigger cubes or supercharger. .

Brian Tooley helped me with my build and am very happy with it ,good parts and great help .. 525 RWHP headers ported stock heads Comp Cam new pump Few other new parts runs great ..

440/400 sounds like a pretty decent set-up already. I would be more concerned as to why both head gaskets are leaking.

I would replace the gasket(s) and sort out/upgrade anything discovered in the process and enjoy as is.

OneEvlZ

Impressive power for n/a. Def gonna look into him. Thank you!!

OneEvlZ

Yea gonna fix the gaskets and anything else i seem to find. Power is good but you always want more lol.

seeing what your car already makes I think you would be disappointed after spending big bucks on a nice set of heads plus another cam and all the associated parts/installation and make maybe 30hp more than what you are now... for the money you are going to spend on all of that you could buy a blower kit and easily make 200hp over what you have now and even more if you wanted to... just my opinion

Acid666

440/400 at the wheels sounds pretty nice to the wheels. I agree, you're not gonna squeeze too much out of it. I'd love to have 400 at the wheels, let alone 440.

STOP! Decide what your goals/uses that you plan for your Corvette, then plan on how to achieve those. At your power level, you're at the cusp of the point of spending alot of money for minor gains, if your needs require a NA setup. As much as I love my BT finished Trickflow heads, I wouldn't have bothered if I would have planned ahead on a supercharger. It's way cheaper to run a little more boost, than to, say, get a ported FAST92 setup, which would be my choice of next mods to stay NA. Unless you scrounge around for used parts, that's about $1500+ for maybe 25 HP. If your budget is more expansive, just SC it next, and replace the head gaskets.

danziger

Exactly what I suggested above. How the car is used and what power levels needed will go a long way towards determining an efficient and cost-effective set-up.

Enjoy it, if you have to do something, get a bigger TB and Fast intake, or take the big lead and get a SC.
