Default About an ls1 in a 1994 v6...

Will you need a new rear-end once you swap in the LS1?

No, the rearends are the same. The only differenence you "may" see is the V6 might not be limited slip, but not 100% sure. If its not, you can keep the same rear, just change the carrier.

What is a carrier and what carrier would you recommend, and about how much do they cost?

it's an open diff 3.08 in the V6. Just get an entire rear axle off of an LT1 or LS1 car.

I would normally say you don't need a whole rear, but if you don't know what a carrier is, your chances of sucessfully swapping one out are greatly reduced and it would probably behoove you to just get the whole axle instead.

The carrier is what the ring gear (from a ring & pinion set) bolts to, and is what turns the axles.

Here is an Auburn style limited slip carrier sitting inside the axle housing with ring gear bolted to it:

To find a used one, go to www.car-part.com.
I did a search for 1994 Camaro, Axle Assembly Rear (w/ Housing) in Kentucky and found a handfull of axles for $300 or less. Just make sure you specify limited slip and make sure you pull the cover off and verify it is a limited slip before you install it.

alright can someone just clear me up...i have been told 3 different things. I know I could just get a new rear-end but that isn't what I want to do. I have been told to get a new carrier, a new axle, and a new rear-end altogether, what do I really want to do if I don't want to get a complete new rear-end and I don't want to spend that much money?

You dont need ANYTHING. The one you have now is just fine to drive the car. The only drawback is that its not positive traction. You would have to buy a posi unit which is the carrier you keep hearing about to make it positive traction. Thats gonna be 400 bucks, so if you could find a complete rearend out of a LT1 car then it will already be positive traction.

One more thing is that you will more than likely get the rear disk brakes with the LT1 rearend which is good.

Alright, thank you. So I won't necessarily NEED the posi unit. In that case I won't have to worry about this rear-end breaking then will I? The car is an auto by the way.

OK, back to my original post, the V6 and V8 rears are the same except the limited slip. If your looking for added strenght, you won't find it with a V8 rear. I only mentioned it because of the benefits of limited slip.
As far as a rear-end or rear axle, thats the same thing, just different terms. A "carrier" swap would convert the non-limited slip into a limited slip, providing you swapped in a limited slip carrier. I felt that entire axle replacement would be better for somebody who might not be able to swap out a carrier.

As far as NEEDING a new rear, absolutely not, you'll just be doing the "one wheel peel" until you upgrade.

Hi I am doing the same swap . What gotting on the Rearend is right . You dont need to change any thing to drive the car . Just dont get in a big hurry to take off . As far as the stringht of the rear end goes . Its less likely to brake if the wheels or wheel in your case spin . Its less of a strain on the rear end . Anyway have you swaped the engine yet . If so how is it running .

I am having a 97 ls1 put into my 94...and all that is needed to get it running is the custom wiring harness...my mechanic that is doing it tried using the factory wiring harness but the computer wouldnt ground 2 of the injectors ...but the custom wiring harness "should" clear up the problem and finish the swap

What would be better though for the rear end...a limited slip carrier or a spool?

A spool is not going to work very well on the street... even in racing spools are weak in a 10bolt...

Spool = both wheels spin 1:1 "very hard to handle on the street

Limited = each wheels spins at different speeds "but the wheel that has less traction spins faster...
