On a whim I looked up the 929 MC and brake booster upgrade. Found a set with 161k miles locally that I'll probably pick up for the hell of it. I never really intended to do this swap as I still have the stock brakes but if the parts check out, why not?
What got me thinking about this was I've increased the height of the accelerator pedal to match the range of motion of the new TB setup. This causes that pedal to be even higher than the brake pedal and I'm worried this'll make it excessively hard to heel-toe. Hopefully the decreased brake pedal range of motion with the 929 MC and booster the pedals will be better matched again. |

While I was at the scrap yard I asked if they had any Miata transmissions lying around. I ended up coming home with this: ![]() Miata transmission without tail housing: ![]() Miata bell housing removed: ![]() Side-by-side with my stock transmission. I wonder why the Miata transmission doesn't have the huge harmonic balancer on the output shaft. ![]() ![]() This is about as far as I got as I'm unsure how to proceed. Everything I've read on the subject just says "swap the 'guts' and modify the input shaft." Not very descriptive. Do I need to swap the output shafts to keep the harmonic balancer? What about the gear housing? Is there an easier way to remove the input shaft than what's outlined in the FSM? Whatever the end may be I plan on cleaning up the housings and painting them and replacing all relevant seals. Lastly, here's the driveshaft bearing in my tail housing: ![]() Is the bearing usually this color or is the bearing toast? FWIW, the bearing on the Miata tail housing looks similar. |
