This website has been more than usefull, so thanks ahead of time to anybody that reads this. I just picked up a running 04 corvette with a T56, that was tboned and not repairable. Engine/trans will be going into my 89 L98. My question is will the rear axle/brakes bolt up? I plan on using anything I can off this car. We'll be pulling everything out next week. hopefully everything goes smoothly, and I'll post up the pics.

You cant use the vette tranny. Its a transaxle type. On a C5, it sits directly next to the rear end. You will need an f-body tranny. Dont bother with the C5 rear end/suspension, youll get all over your head with this... Better not attempt anything this crazy if you are not a super fabricator. My 2 cents.

The rear calipers will bolt onto LS1 backing plates but aside from that i dont think much else from the rear of the car is really practical to use for your swap. Theres been a few threads pop up over the years about guys trying to swap in a Vette IRS rear but to my knowledge it has yet to be done successfully although I dont really browse the fabrication section anymore so perhaps theres fresher info. I think you can buy parts to mod the transaxle trans to make it into a regular t56 but your best to check with sixspeedsinc on that one. They may offer you a trade in core value for the vette towards an f body version.
wow ... now that's sexy. I wonder how much it would cost for a complete IRS setup.
No person or company makes a kit to put IRS in a 3rd gen.
They are all custom installed. Ggeometry is essential.because the LCA mounts are cut off. Once you hit that point, there's no going back! Get it right....or ruin your car.

Yea, I understand that. I meant how much it would cost for the complete IRS assembly from a C4, pretty much wheel to wheel. with proper measurements, it shouldn't be too difficult to install one, even with the custom fabrication.
I need to redo the crossmember, as I don't like the exhaust routing under the framerails.
wow old post, but yeah drag racing. Those little dana pieces blow up pretty good, the 44's arnt too bad though.. IIRC the 34 or 44 are both stronger than our factory 10 bolts..
I dont mean to hijack or anything, just a quick question. Are these your manifolds? I have a similar swap and my custom LT are leaky and damaged...thought about trying these out, if anyone knows wether or not they fit-let me know.
How about 07 Cadillac STS IRS ebay link http://cgi.ebay.com/ebaymotors/ws/eB...link:middle:us Bolt in or what changes will be needed. My 87 GTA aussi 9 bolt is on it's way out, been wanting to do this for sometime, now I'm getting forced in. Thanks for any help you can provide.

I know of a local guy who put in a LS1/T56. CTS-V IRS into his....... ......... MIATA! And all under a 100% (exterior-wise) stock Miata body. Looking it with the hood closed, you'd never guess.

Well I can safely say it will not be a direct bolt-in. It will obviously take a considerable amount of fabrication to do it correctly. Is it even close to the proper width?

LS2 vette manifolds.
