LSD for RX3
Can a FB RX7 LSD fit directly into an RX3 differential?
What is the best disk brake conversion ? Thanks. |
LSD has to be from 81-early 83 gsl rx7.
I got one for sale for the right price;) |

This is what it looks like with the stock RX7 brakes from the same dif

throw a hilux into it proven time and time again here in Australia!
|
We don't really have hilux up here.

Hilux rear is the same as the 4runner I believe.
But your best bet is to do the ford explorer 8.8 rear diff.its a 8.8 31 spline with limited slip but would need to be resized to fit. You would only need those type of rear ends if running big horsepower but for n/a applications you might be able to get away with just the rx7 gsl third member and disk brakes. |
Thanks, is there anyone in USA running a 4runner 3rd member in a rx3? Heard of the Ford rear end, but that's to much for my application. What is the best way of finding our if a vehicle is equipped with an LSD without taking the diff apart or doing donuts?

Depending on the car.
If your looking at the 81-83 rx7 diff it would be the gsl model,disk brakes. You can also spin it from where the driveshaft bolts up to and make sure both wheels spin the same direction. If you are looking at the explorer diffs best years are from 95-97 and the door tag under axle would be D2,D4,D3. D2 would be the best gear ratio for a rotary which is 4.10 |

By the way , when is test and tune day ?:nod: |
just the parts
I used the 3rd member and adapter brackets for the brakes.
I found a number of forum posts indicting that the RX3 axles would bind in the 3rd member unless some material was removed from the end of the axle. All my test fits indicated no binding and I did not shorten the axles. So far so good. I've got the leaking oil pressure gauge issue resolved and she is running predictable, idle around 900, sounding good. Tied up with some side work to pay for the recovered seats. Still have to get some jets. My body guy is taking the car back for a few days next month to tidy a few things up, Then I want to take it up to CR. |
Cool , keep me updated. I have been busy building engines so the car has stalled but I want to get doing the rear end soon as I have those Konis now too. Back to the LSD question though ; the snout / pinion length was different I seem to remember so if I put my 7 LSD in the 3 housing , will I have to change driveshaft length? I currently have the 808 auto 4:11 diff in there now.

You can transfer the or install the 808s ring and pinion on an 81-83 lsd

Just really looking for a Mazda LSD to fit in the original diff and convert to disk brakes. Are the guys making the disk brake conversion kit still around?
