Yes I have the Torsen. I tried it on Trademe but no bids. Here are the
details:
Add that missing punch to your 93 onwards MX5. Easy to fit and great
performance boost particularly 0-100kph but will also take you to over
200kph. 4.3:1 is the same ratio as the early 1600's. In 93/94 they
changed to 4.1:1 and back to 4.3:1 for 99.
Check out the Mazda sites, you will find that this is the diff of choice
and only came out in 99. As it only alters the rpm by approximately 300
in 5th, there is no need to change the speedo drive. Approximately a 7
kph difference @ 100kph.
As new condition
I purchased the diff from Mazspare out of a 99 car that had done 1000km.
Have run it for a year commuting since. No longer building a Targa car.
Diff is complete and can be fitted in less than an hour. No parts needed
for a swap.
