Brake master cylinder compatibility
I have a '89 GTUs, and i had a few questions about my brake master cylinder. does my car have the s5 n/a brake master cylinder or does it have the s5 turbo master cylinder? Also i was wondering if my car does have the s5 n/a master cylinder can i install the s5 turbo master cylinder with little/no modifications? any information would be greatly appreciated.

If your GTUs has the 4-piston front caliper system I believe you will need the Turbo master cylinder. The Turbo MC is different from the non-turbo equivalent. MC selection depends to some extent on whether or not the car has ABS and/or AAS. Give Mazdatrix a call (562-426-7960) to verify before ordering. See this page to see what I mean:

Hmmm, I thought the GTUs had the Turbo brakes. Guess I was wrong. First time.
Edit: Well don't be surprised it you really do need the Turbo MC. See the sheet at the bottom of the following page:

People forget that the GXL, 91 Coupe A Package and other NA cars also came with 4 piston calipers. 4 piston calipers do not represent Turbo brakes, I'm not sure where that started.
Use the NA Master Cylinder, but look at Mazdatrix's site and see if there's a difference in the MC between single piston front brakes and 4 piston front brakes for NA cars.

I did a 5 lug Swap with 4 piston calipers up front.I used the N/A master cylinder and it Works Just Dandy!.I have done THREE swaps like this and No problems.I haven't however done anything with ABS crap on it.(old school.Abs wasn't invented when I got my Licence!).
