Rear End Swap Ideas

[Scott R]

I have a 1994 Camaro with the 3.4 and an automatic transmission. I was wondering if anyone has ever bolted a Z28 Rear right into the car, I mean take out the old V6 Rear and just put the Z28 Rear end in with the disc brakes. I want to convert my brakes over to disc anyway, I have already read the article that was posted about them on this site. And another question I have is do I have to reflash my computer because of the change in gears.

Yes, swapping the Z28 rear end is the easiest way to to get LSD gears and disc brakes. People do it all of the time. Just make sure you get the right year for TCS and what not.

Yes, you'll have to reflash your PCM for the change in gears. You can drive without re-flashing, but your speedometer will be off and your limiter will be lower.

Keep in mind;
The Z28 rear is a "Direct Bolt-In". No modds needed. Any 93 thru 97 Z28 rear will work perfectly for your 94 3.4.

The only thing you'll need is Emergency Brake Cables for disk brakes. The ones currently on your drum setup are not compatible. Other than that, you're good to go! :D

yep did it, its actully pretty easy...


Just really need to bleed the brakes well, only problem I rain into, took forever to get all the air out.

direct bolt in, easy swap, for the most part.

I did it too, put a 2000 in my 99. Great rear end. Easy swap. Had it done in two hours using a friends shop. Speedo still off though :( Went from open 3.08's to LSD w/3.42's.

how much would this send the speedo out of wack...where can you get the PCM reflashed, a dealership, or a aftermarket place...???

Depends what year and such your car is...

older cars, OBDI think is harder, newere ones you can do it wiht hypertech, or hptuners.

But in my opinion if your cars is old and you hae a 5-speed, doesn't matter if your speedo is off, just know by how much and your fine, only thing to worry about is your odometer. But if your car is like 100+k doesn't really matter too much what your mileage is.

My car is a 95 3.4L automactic...would a aftermarket place have a hypertech or would i have to buy one...dont have much money to spend till i get insurance paid off...

so wat if you did the swap and put a Z28 cluster in how bad would the speedo be off...i want to do that but i also need to find someone who could reflash the comp...

[shenanigans]

z28 cluster won't fix speedo problem...

not sure on the costs of getting the comp reflashed.
