Thats pretty sweet, how does it perform in the miata?

This is one case where I really enjoyed the engrish..only because it's clear your mechnical skills are pretty good. Hellofa great modification and should take anything you can throw at it.
How is the gearing compared to the Miata transmission? Much longer now? |

Nice first post!

Turtle = bellhousing.
Anything else you guys want me to translate? :laugh: |
Very nice explanation. Does the gearcase contact the under body of the car anywhere?
|
I have my old FD transmission sitting in my garage and a 5 spd Miata trans in my basement... hmmm... weekend project?
How did you take the measurements to have the PPF line up correctly? And what about the pull clutch mechanism on the FD trans? What did you do to convert it to push, and what throw out bearing/clutch fork etc. did you use? |
Nice entry post. I started to read the thread and got scared then realized that one you are from another country. Two that you managed to do in your back yard what a lot of people will not attempt in a shop with good tools. Hell of a job I hope it holds up well for you.

The fc and fd transmission are holding well up to 500hp.
Here are the ratios http://www.solomiata.com/Drivetrain.html Dogits your mechanical skills rock for real but your engreeklish are funny as hell! |

Looks like the stock miata clutch system. Pretty nice how about the drive shaft? How much total labor and money. Nice build
