ZO6 performance???

[Ryan G]

I'm guessing this is the right section to post this, hopefully I'll get more answers here than I did at ls1.com and ls1tech.com.

Well, I'll try and make this quick! I'm a current owner of a 95' Toyota Supra Turbo and I'm thinking about getting a zo6 in the near future if the outcome of this thread is positive!
Here is my question to you corvette guru's.
How hard is it to modify a zo6? My friend has a SS camaro and I know that you can do things to ls1's and what not. But the zo6 comes out of the factory pretty much modified to the extreme.
I was looking at getting a 02' zo6 and I'm curious as to what all you can do to up the whp? I mean can you do the normal, i/h/e? I know it already has the ls6 intake mani and cam, but are there bigger cams you can get that make it trap 120mph+ pretty easily?
I'm on stock twins right now and have run a 12.4@116mph on street tires! I'm around 400+ whp and I'm wanting something that will do 120+ trap easily like I stated before!
I could just go single with the supra and be very powerful, but I'm just looking for something new.
Could someone please explain to me how hard it would be to make a 450whp zo6? Please don't say supercharger, because I already know thats a possibility. But I'm wanting easy modifications, such as i/h/e and possibly a cam if needed.
I know its not as easy to get good whp numbers out of N/A's, but I would like to kinda get a ball park range of what different performance mods will yeild!
Thanks so much for your help guys,

Ryan, welcome to the mature site.

You're looking to get 450 rwhp. Is that all?
If you look at the sigs, guys get anywhere from 400 - 1016 rwhp. If you want to stay N/A you can have as much as 600 rwhp.

Okay, there's heads/cam + LTs... that would be about 450 rwhp.

You want more? Go higher in CIs and all the goodies (N/A) and you can get up to 600 rwhp.

You go up in cubes and blower and you can make 700+ easy.

You can stick with stock CIs and build your motor and slap a TT setup and be over 1000 rwhp.

Have fun and feel free to ask guys here for help.

In case you don't know, we're a little biased towards the Z06. Go out and get one and tell us how much you like it.

Welcome aboard,
Alex

You can cam & head to easily get 450 HP, You can bore and stroke to get 550 HP, Darden wet sleeves are available, The C5R engine makes 650 HP normally asperated, and C5R parts are available (block & heads).

There are SC and Turbos to get you to 750-850 HP. There are twin turbo set-ups to get you to 900-1,000 HP

The old racing adage is true - How much money do you have and how fast do you want to go??

You also have to ask yourself are you looking for all out straight line performance. The Z06 will corner better than the Supra I'm sure. I can't say with confidence, because I don't know what suspension upgrades you've made, but stock for stock I can say it will. I just had a cam installed with headers, and I am at 403 rwhp. I am also looking for close to 450 rwhp and have a set of AFR 205s heads in mind to get me there. You have to remember too, this car is fast stock running, in some cases, high 11's @ 117. Drive one and see how you like it and make your decision from there. Good luck with your decision.

Welcome to the forum!

The Z06 is very easy to modify to whatever power levels you want. You're really only limited by your wallet and traction. There's a vast array of aftermarket parts available and some excellent tuner shops that specialize only in the Corvette.

IMO, your best bet for 450 rwhp while staying naturally aspirated would be a good heads & cam package, headers, intake, and tuning. The new AFR heads are making some tremendous power.

I'm on stock twins right now and have run a 12.4@116mph on street tires! I'm around 400+ whp and I'm wanting something that will do 120+ trap easily like I stated before!

Keep in mind that a bone stock Z06 on street tires with an average driver will turn the exact same time and trap that you are getting now with your Supra. Great drivers have gotten them into the high 11's bone stock, but with obviously the same trap speed.

Also remember that the Z06 weighs considerably less than the Supra (a good 400-500 lbs. less), which means each horsepower you add will have a more dramatic effect on acceleration, and it takes far less rwhp in a Z06 to achieve the same quarte mile and trap speeds as a Supra. For example, as I mentioned I'm at only 380rwhp, and my car is already capable of 120 trap speeds. With 450rwhp, you should be at LEAST in the mid 120's.

However, I can't say that its exactly cheap to modify Z06s. Its certainly less expensive to crank up the boost on a Supra Turbo for the power gains. For reference, it cost me just under $3k for my mods which include headers, intake, exhaust, and dyno tuning. That's a lot of money for only 30 rwhp. But, it got my car in to the high 11's with 120 traps, so when you look at it that way, its not that expensive I guess. Certainly much cheaper than modifying Porsches or any other German car, that's for sure.

Good luck with your decision. You won't be disappointed with the Z06. We have many ex-Supra owners here on this board who now have Z06's, so they can provide a real comparison.
