Ok so I have an 2004 z06 with about 14k miles on it. What are some quality performance upgrades I can add? Maybe to get up to 500hp. What are some things you have down with success?

i got to 440rwhp by adding a vararam, ar headers and an england cam along with a tune. probably with head work you cound get 500 hp. 440 is plenty for the type of driving i do... i am real happy with the souund and set up

I am a firm believer in boost. If you want power and driveability, boost it. If that interests you, look in to a twin turbo kit, or any of the centrifugal supercharger kits. Lots of good vendors on here can help you out. 500hp is cake with psi+proper camshaft and you can still keep the original hard engine parts.

Very impressed with that # from those mods. congrats! enjoy.

Do you want 500hp at the motor (adding ~100 hp over stock) or 500hp at the wheels (adding ~150hp over stock)?

What's your budget?

LT-1 kid

at 500 hp things start to break, cai,Lt headers,and a tune puts you at 400 , I think thats perfect for a stock z

If you just installed an a&a blower kit with a large 3.8" pulley. You would put down at a low 525rwhp.would be a new car and would drive EXACTLY the same until 3,000+rpms.

I vote for Seat Time...AKA the Driver Mod! Can't beat it

What do you plan to do with the car?

The combo of CAI, LTs and tune is proven effective. You could always do a small cam with supporting mods afterwards...

Bang-for-buck...can't beat nitrous.

500HP in a N/A car will drive like crap on the street. 500HP FI will be easier to drive and probally a cheaper build as well.

Mine drives just fine. Not sure what makes you say that

True, but that stuff scares me. I wouldn't do that to another motor of mine
