Z06 Coupe Conversion
I have an '02 Coupe (A4) that I love dearly, but I would love to have 100% Z06 performance. Not just HP, but suspension, gears, brakes, etc.
I have been doing all the usual bolt-ons, 3.42s, 2800 TC, Corsa Indies, Vararam, Power Duct, 85mm throttle body, and I have Kook's LT headers on the way.
It just seems to me that I am in a never ending cycle of modding the next "weak link" in my car, and no matter what I do, I am still chasing a moving target (a modded Z06).
What I would really love to do is take my Coupe and marry it to a Z06 running gear! Does this sound insane? Has anyone ever tried it? Any advice is appreciated, and I am really serious!
Please, don't tell me to buy a Z06, because I love the Coupe's body style, removable top, etc.
Thanks

Did you say that you were chasing a "modded" Z06. Hardly worth the time, effort or expense IMO.
You will have to upgrade your entire suspension, shocks, swaybars, and tires, plus change front brake pads, you'll need heads and cam, and programming.
I'm figuring around another 85-90hp total above your stock 350HP, to make up for the additive effect of the Z06s HP, gearing, and weight advantages. Once you do the heads and cam, it won't be to long before you will need a stronger automatic transmission to handle the new power. The Z is lighter, more powerful, and geared more aggressively.
Swapping out your own drivetrain for an entire Z06 drivetrain still does not address the handling issue.
In the end, with your automatic, it'll be tough to match the Z in both straight line performance and performance in the twisties.. Might be a bit easier if you had a stick.
You may get to Z06 straight line performance or beyond. But with that auto, it won't be easy to match a well driven "modded" Z06 on a road course, even if you do suspension upgrades

Do a stage II LS1 head job and a Comp Cams X218/224/581/115 cam, some mid length headers and a good tune.
Hotchkiss or T1 bars, Billsteins, higher durometer bushings, street/strip brake pads and either ZO6 or other after market springs (I put in a set of used ZO6 springs).
Get a set of 18" reproduction ZO6 chromies and 275/295 18" BFG KD's and go out and KILL those ZO6's (is that blasphemy?).
Any way that's sorta what I did!

As for the Caravaggio Z06 to Coupe upgrade, this sounds very interesting to me, except that I would first have to trade in my coupe for a Z06. Still a possibility, though. I think the $15,000 upgrade is not too bad, though. I could easily see that many mods on my existing coupe.
Thanks for the ideas. Keep them coming!

Or waiting for the C6 Z06?
I think the C6 is probably a very good option, but with two conditions:
1. I want to wait a couple of years until the inevitable "bugs" are worked out.
2. I can buy on GMS pricing, which will probably take a while until the dealers are willing to offer it.
When the C6 first came out, I wasn't for sure, but there are about a hundred of them running around Bowling Green now, and they are really starting to grow on me!
I really love living in "Vette City"!
That also sounds like a very likely option. There is a local company called Total Engine Airflow (TEA) that does heads / cam work, and I have heard some very good things about their work.
Has anyone else on the forum used TEA's heads and cam?
