Hello, instead of finishing my project I may just be looking at getting a vette. I'm not so interested in a C5. C6 is definitely pushing my budget but it's worth. I'm considering the 06/7 Vs a 08.

Personally I don't care about the ls3. My plans would be to eventually turbo the vette down the road to make 600whp or so. Procharger might be easier r but I'm from the supra world and turbos are addicting.

I'm mostly concerned about the t56 Vs 6060. In your opinion on a daily would the t56 with a clutch be able to handle that kind of torque? Is it hard to upgrade it for a bit more? Or swap to 6060 later? I have a guy who will work on my transmission for free. However I still have to buy parts.

I will be driving the car spirited but it's a daily, not a track car. I may take it to the strip once or twice to see what It could run. But all this would be at least a year down the road.

Save and/or wait for the '08. Better trans, better rear, better interior, and even though you say you don't care the LS3 is superior to a LS2. I make 881rwhp on a stock bottom end LS3 with a D1SC on e85. 600rwhp is nothing for a LS3.

PM me if you have any questions.

The ls3 is nice. Dream one day would be a big single iron block bottom 1000+ hp but I think Im gonna keep the vette as an awesome daily and make my supra into a drag car.

Say if I did get the ls3, and ran a twin turbo kit such as ttix or upp. Are those the main ones still available? What would I need to support those turbo kits at their base 7psi or so.

Assuming, clutch injectors and tune?

Just a good tune, proper fueling, and that's really it. Don't need a bunch of mods. I threw the ProCharger kit on my car with a clutch, injectors, and make a easy 630 on 8psi.

Go ls3. Besides the trans and rear, the engine is really that much better. Heads are fantastic, as is the intake. A single turbo is tough to do without hacking a bunch of stuff (I do a lot of fab work, trust me), so you ll pretty much have to go twins. Superchargers are easy as are rear mounts

We'll you guys helped make up my decision.

Going to be hard to find an 08 coupe manual at 100k+ plus. Kbb says they're valued around 16k but I doubt it'll be that cheap. May just have to turn the supra into a drag car if I can't!

Also curious on the 06+ automatics. How do the feel or run compared to the manual? Can they be tuned for higher pressure to hold more tq and quicker shift response?

fuel, clutch,boost,+LS3..hard to beat combo.

Tr6060, better interior, and better/newer design diff.

I have an 06 6l80 APS TT car in the shop right now with it's second BUILT trans. It has never seen a race track...and hardly ever beat on. I'd say as long as you have proper gear engagement,...the 6060 will outlast an auto.

Cool man. Will the ls3 survive stock at like 600-700whp?.. I don't want to open it up. At most I'd do ls9 gaskets to lower comp a bit and arp bolts.

Assuming I do a bolt on kit, do not open the motor in any way. Get a clutch injectors and tune, what can that motor run safely for a long time?

600-700 is easy. I've pushed mine to 630,676,702,740,780,and now 881. A prope tune and fueling is key.

CowsGoMooo

Nice did you drop compression or run e85? Any head work required?

CowsGoMooo

Also meant to ask. From my research all the issues to do with the 6 speed is the electronic clutch system rather than the actual durability?

Detoxx03

Stock compression. I ran 93 octane until a recently. I started running e85 around March. Heads are stock.

I thought the rear differential is the same from 2006 to 2013... I agree that the LS3 stock for stock is much stronger then the LS2 but when you add some boost and mods that all goes out the window.. then it becomes all about the combination and tuner.

LS3 A6 here.like others have mentioned save wait for the ls3.more upgrades from the ls2.goin supercharge with mine main purpose is for roll racing on the streets since we dont have a track anymore.

CowsGoMooo

Everyone else has money ha. I don't see a good reason to wait anyomre since the t56 can handle 600whp fine.

Detoxx mentioned the advantage of the LS3. disadvantage of the LS2 just for FYI.Stock intake and heads are restrictive.

CowsGoMooo

Yes I understand all that. if I fin da good deal why not but I doubt it's worth an extra 5gs for 30hp. Also I've learned the ls2 is plenty capable of putting down 600whp with just some fuel upgrades and turbos so that would be plenty for me! Anything more seems like a waste on a daily.

Also I'm curiuos how good is the traction control system onthese cars? Does it actually help you get grip or just puts the hammer down on your accel? Can they be programmed to work well with more power?

Detoxx03

Traction control is meh at best. I drive with it off anyway though.

It's not the 30hp stock you'd be getting as an advantage. I don't think you're listening to us.

you can get a higher mileage '08 for mid 20's...

If you don't plan on doing a cam or heads then I would just leave the compression alone...ESPECIALLY if you are going to rock e85. If you decide to really up the boost...do a cam and LS9 gaskets...should be golden.


This.

Really not sure what you mean bud.

Do you mean the hydraulic clutch system? If so, basic maintenance will make the hydraulics last longer. If you are going to go through the extent of changing the clutch, I would recommend a remote bleeder, and perhaps a higher performance master and slave cylinder....although people rock stock stuff and seems to work. Me, I had to run all aftermarket due to configuration. I don't want your head to explode with a bunch of stuff that doesn't pertain to a LS3 based C6(I have an older frankenstein model). Detoxx seems to have a pretty good example of what the platform is capable of without a giant laundry list of rare parts. I would mock his setup if I where you, relatively anyways.

Keep it simple. You'll live a happier life with the car.
