I have a 1985 rx7 base model with drum break. I have a guy who sale 1983 GSL rear end with LSD. What do I need to get this swap done. And Can RX2 carb fit on my car? Thanks guy...

They're both solid axle so the swap shouldn't be too bad, the biggest issue you'll have is setting up the parking brake since they're two different kinds of systems. once you swap the axles then you should be able to hook up the brake lines and make sure you bleed them. as for the carb......i think all of them had nikki carbs but i don't think they changed the way they mount at all so it shouldn't be an issue as long as they didn't change the manifold mount. best of luck man and i wish the best. if you can get the rx2 intake manifold too because the mounts onto the block are the same

I Dropped a 1983 GSL LSD with disk breaks into my 1980 RX7 Everything bolted up the same. The big thing was the break lines. The drum breaks use a different fitting than the Disk. I make that mistake to the tune of $100 bucks. I threw away the old line before I new I needed the disk break side. I then had to find the right fitting and have them custom made. They are braided stainless steel so they should out last everything else on the car.



Also it seemed like there was about 15 bolts I had to remove. Keep in mind the suspension will be fully extended while you do the swap so things won't line up correctly. I also had a transmission jack with fine adjustment ***** for the tilt on the lift plate. I lashed the whole axle to the Lift Plate and and used the fine adjustments to get it aligned it also allowed me to compress the suspension to help with the alignment . It only took me 20 minutes to put it in. With that jack I didn't have to fight anything I could move it until things slipped into place. I would rent one you will thank you self later.



Just go slow and pay attention to the order you removed the shocks and sway-bar. Enjoy.
