1991 Corvette M6 - Lots of mods/parts - F-Body Road Racing and Autocross Forums

I've decided to sell my 1991 Corvette M6. This is going to be a little long, but here's the scoop...(copied as I posted it on other forums, so this wasn't frrax specific):

I had a 1992 Z28 autocross car and I decided I wanted a street car. I pulled the engine out of the Z28 (approximately 1,200 miles on it since it was built) and bought a Corvette. I put a set of Trick Flow 175 heads on it and a TPIS Miniram II as well as a TPIS throttle body and did a complete teardown and refresh before putting it in the Corvette (rod/main bearings, had the crank polished, new cam bearings, all gaskets and seals, new heads, new intake, new throttle body). I bought a Canton road race pan for it, stainless works long tube headers and a Dewitt radiator and started putting it together. The transmission was converted to crash through and a Hurst shifter was installed. I also ordered all the weather stripping for it and changed some (the rest is in a box) as I had time. The heads, intake, clutch, flywheel and distributor have about 40 miles on them, the throttle body and injectors are less than that and I installed the Borla kit last weekend....it's brand new). I've paid for two proms from two reputable places and I've been working on cleaning up the tune and some driveablility issues and I'm finally tired of spending my time and money tuning it and not driving it. So...I'm listing it for sale. I have a pile of money in this car, I'm asking far less than I have in it and I'm not looking to go much lower on it. I don't have to get rid of it, but I think I'm going to go C6 shopping and send this to a good home. I'm selling the car and the collection of parts I have for it as a lot.

It's red with black leather and has 117 k miles on the chassis and a 6 speed with 3.45 gears (dual power seats, electronic climate controls).

I'll save time and just start a parts list:

350 bored .020 over with splayed main caps and two bolt studs (and a billet front bearing cap on the #1 main)
Forged crank (ZZ3 crank)
Lunati Street Race rods (5.7") with floating pins.

Accell 36 lb injectors (a second older set also included)
A box of weather stripping (the stuff I haven't installed)
Both tops (tinted and body color)
JVC in dash DVD player with hands free/bluetooth and Rockford rear speakers (fronts are in a box, I never got time to install those)
Hurst shift knob
AC has been converted to R134 (but I was planning to change it back to R12).

I'm sure there's more and I'll go through the garage and update this. I'd rather find someone who wants to finish the tune and enjoy it instead of parting it out.

So, in a nutshell, if you like tuning these cars and want a car with a lot of nice stuff in it and a bonus shortblock as well as 4 sets of wheels....look me up.

Pics on request.

I've tuned MAF and MAP cars. I have 2 heavily modded TPI383 Thirdgens. Both run and drive like stock, Austin can vouch for my ability, heck he's auto crossed and driven my IROC. I too would like to see you finish and enjoy this car, and I'm 100% confident I can help or do the tune for you. Mail order chips for a combination like this will never work, they won't even get you in the ballpark IMO. I realize I'm stomping on reputable tuners toes there, but when it comes to tuning this OBD1 stuff you can't do it through the mail. Contact me, I will help. P.S. I haven't made a major change to the tune in my IROC in years, and I haven't messed with the GTA in over a year as well. Once I get them "done" you won't have to mess with it ever again unless you make mechanical changes. This post has been edited by 1meanZ: Jul 24 2014, 01:31 AM

Once I get them "done" you won't have to mess with it ever again unless you make mechanical changes. I didn't figure they'd get it exactly right. I've had mail order tunes before. My Camaro ran on a mail order tune that was pretty rich, but ran ok so we left it. I really figured TPIS could get it pretty close. They are/were selling that engine package I posted that's extremely similar to my motor. However, I'm running smaller intake runners on the heads and that seems to be leaning it out down low (I seem to have better cylinder filling down in the 1,200-2,500 rpm range than they did with the larger runners....despite similar flowbench numbers). And I'm fighting with timing tables and accelerator pump issues (and I'm not sure which setting is truly accelerator pump). I'd like to finish it at this point, but I really am losing my ability to care. I wasn't kidding about making a good effort to finish. I put a Borla exhaust on it last weekend (it's seen 25 minutes of run time) and ordered Koni SA's from Sam Strano last week as well. The tires are brand new (40 miles) and I just changed out the injectors to 36 lb/hr Accel injectors (to try to keep the trip computer accurate) and bought a TPIS throttle body (several grand in parts in the last couple months). I've just had it with the tuning issues....
