Ok guys, my dad has an 03 Z06 and wants to buy some parts to compete against my 03 Cobra since he is stock . Anyways he is bone stock, and if money is not a problem, nor is legal inspections or whatever, what all would you buy that is not too expensive. He would like head/cam/intake/full exhaust and whatever else you guys would suggest, but with out having to buy a new engine, or whatever. Also, no nitrous. But what exact cam and head pacakge would you get to get the most horesepower out of it? Thanks for any replys guys!

He shouldn't have to compete. If your stock, he already owns your azz. Instead of buying parts, he should just learn how to drive it. It's the best mod for a z. There's several guys who have been into the 11's with virtually stock z's and low 12's can be had with little effort.

All I have is cat back, midpipe, and cat back, and drag radials, and I can beat him from a 30-90mph roll, not by much though, and I have raced another Z06 from a 10mph roll and beat it, but they were both stock, but I am not trying to start a battle here, both are bad *** cars that I love, my dad and I just want to make the Z06 a beast .

Well on to what to make the stock Z06 faster. First a CAI, I love the vararam but lots of people like the halltech stinger and the callaway honker CAI. A good set of headers and X-pipe. Look into a cam and heads package from Texas-speed. That have some good product for a great price.

Although if you are going to spend that much, spend a little more, just go with a supercharger and be done with it. Procharger all the way. Easy 550-600rwhp. REally depends what your dad wants to do to the car. Couple different route

the Z should beat you even if its stock down to the paper air filter. Not by a little either....by quite a bit.

Full exhaust, CAI, DRs, and a tune will get him deep into the 11s. The exhaust and CAI should be the 1st mods.

So would he be good with a supercharger, the internals that is? Will it be safe or will we have to forge the internals or what? I was also thinking some SLP exhaust set up too, don't know if they are good or not though.

We all know that his Dad does not rag his Z like us!!!

Were do you live? Find a local car place or if money isn't a issue then ship that beast to someone and get r done! A good h/c package should put your dad at 450+whp.... Then he will be smoking your Ford!!! Tell him to start with the Hurst shifter, intake and a tune! Then he will still smoke your ford!

With the price he would pay for a Heads/Cam, headers etc package he could easily get a supercharger and be done with it. He will easily be at 500-550 whp on low boost and still keep the bottom end stock. Just get a good tune and it will be safe.

C'mon guys lets not start a Cobra vs Z06 debate. 1/4 mile we all know they are pretty close. If stock vs stock yeah a Z06 will pull, but it would be 3rd gear and up. Believe me Ive owned/own both.

WLG101190

Well maybe we should just get a supercharger, so what is the best cam to get for boost? And is ProCharger the best supercharger kit to buy for the Z? Thanks!

all he needs are drag radials and that Z owns your cobra

Based on your dad's "need" to turn his c5 z into a beast I have just what the dr ordered.

Check your PM box for the 500 rwhp recipe. Trust me on this. Check your PM.

The ECS (East Coast Supercharging) Paxton Novi supercharger kit is hands down the best C5 kit. 550+ rwhp on an otherwise stock Z06. The kit will make more than the stock bottom end can handle with the stock cam, so unless you’re going to go with a forged short block a new cam is not needed. It would be a good idea to upgrade the clutch and the rear end output shafts too.

Supercharger.

WLG101190

Alright well I was thinking maybe, a cam specifically made for boost or whatever, some long tube headers, o/r x pipe, cat back, CAI, and a a supercharger, but is the centrifugel supercharger the best for these cars or the twin screw?

If you go with a twin screw, you'll need to change the hood to get it to fit. Coming from a 600hp Cobra with a twin screw to a Vette with a centrifugal Sc, I like the centri better. On the street with a twin screw its worthless if you not on some good dr's and even then you spin. I like the lag so to speak with a centri. As for cam the stock Z06 is a great cam at the power level you guys are looking at. Also you could look into the Vortech kit from A&A, its a great kit as well.

That is the kit my brother has on his Z....he really likes it.

What about building up a 404ci or so LS engine from Texas-Speed with forged internals. Can we make an all motor car that runs 10's or so? Say we built the 404ci stroker kit, put on some good heads, nice cam, and intake/exhaust. Would it be worth it to do that, or just to mod his 346ci stock motor? Thanks guys for all of your input!

Lol, it all comes down to what you want to do and how much you want to spend. IMO the most cost effective way to make good power is a supercharger. 500+ hp for around $7-7500 installed and tuned (cheaper if you do some of the install) I ahve a built TSP 347 in my car, and so far its doing great. But again its up to you, a 402 or 408 and a nice shot of nitrous would be sweet too

bolt ons and a d1 ???!

GET_SOM

Let's say he does go the bolt-ons/ FI setup... or even just decides to go up to a 408... are there more significant gains seen having a c5z rather than just having a c5 coupe/ frc?
