Looking to upgrade stock brake booster/master, clutch master/slave. I heard the 1st Gen's will work - not sure of the year tho. Part numbers will be helpful.

Any input is appreciated.

TIA

Let me know what you find out. I need to replace the booster on mine, was just going to go with a stock one due to space limitations. I don't think a 1st gen RX-7s will fit, they are much larger unless you're talking 79/80 (I think they're smaller). Maybe a RX-2 one would fit, but it's not really much bigger than the RX-3 booster.

the 79-80 brake booster are smaller than the 81-85. I will compare the SA and RX-3 brake booster since i will working on a SA this weeknd.

Master cylinder: any of the 1st gens wont work as the brake fluid reservoir wont clear the strut tower. Research to be conducted since I have a spare RX-3 and 1st gen MC's.

Clutch Master:
Been told that any of the 1st gens would work except have to drill out one of the studs.

4s will fit if you slot the holes a little

I used a 85 12a cars clutch master and slave on my 72 RX3 and didnt have to mod anything. I have a 79 tranny and the slave fit just fine.

use anything you want just drill new holes and make it happen
