Well on a update from my blown rear end, I scored a low milage (only 65,000 on the car!) 83 GSL rear end (for 80 bucks w/ a drive shaft!) at one of the pick-a-parts in ventura few days ago and I got it all in my 79 today.

After a bit of problems with the brake line fitting (I had a slight problem with re-flaring the rear line) I got the brakes bled and took off. Man the rear end is much smoother and quieter.

The brakes on the rex are just amazing I can't believe mazda even offered the car with drums. 4 wheel discs on this car just puts the old setup to shame.

Oh yeah the car hooks up now, I no longer spin forever..

Yea Haaaa---

you had problems with the break lines fitting because they have a different thread pitch..the 79/80 had a different pitch than the 81-85. figured someone would have told you that before you did the swap.

hope they donot leak on you..

 

Can you power brakestill on GSL /GSLSE REAR cause of the disc brakes?

 

Lsd = fun

They sure are

haha, sweet vid.

 

It aint rotary tho LOL

Sweet tho...

 

did you swap the master cylinder? Everything I've read/heard says you should.

 

RiffRaff- Yes I know the fittings are different, hence I said I had problems re-flaring the rear line. I got the proper brake fitting off the 83 brake line, threaded in perfectly.

SoRRow- Of course!

82transam - No need to the stock master cylinder has more then enough volume to fill four calipers, now if I did a 4 piston setup up front then I would. I've done disc brake swaps on bugs before and never had to swap the master cyl. on those either.

The car stops on a dime now.

laters -

someone 82, off topic but how did you get that airdam on. did it fit ok even though its for the 81-85, or did you had to do any custom fitting??

 

I converted my front end to a FB front end after I got into an accident.
I got the fenders, bumper, bumper shocks, etc... It all bolts right up to all the SA mounting holes minus the lower fender supports which the SA's don't have, but doesn't pose a problem.

So that car in the vid has a V8? I waswondering why it was making so much smoke and spinning so violently.... My old 85 didn't do that...

 

sure doesn't sound like a V8....

almost any car with an lsd can do that.. i have vid of me doing that in my school parking lot. (mods in my sig.) not bashing the video, it was badass, i even linked it from my aim buddy list. but after you break loose, just keeping it going

 

It will do that from a 30-40mph roll if I want it to also Really need some better tires.
The car has a 2.3turbo piston motor in it. (flame suit is on) All junkyard parts and putting down around 250hp at the wheels. About $600 total investment.
If I could do a rotory turbo that would make that much hp and be stone reliable up to around 400hp at the wheels for the same amount I would. But I am poor. Most expensive part on the car is the wing I bought from Mike P

PS...Mike...when we going to run them

Thanks, I didn't have sound so I assumed based on Mike's post.
