Silver JDM MR S surprise package.

[Carolyn]

I had been told that JDM (Japanese Domestic Market) cars don't have Limited Slip Differentials.  Today, thanks to all the recent gearbox/gear ratio discussion, I did some research.  First thing I found was our Mr. Spit, who does know his stuff about these cars, said that LSD was an option on JDM cars and the way you find out is to look at the transaxle number on the Vin plate.  If it ends in an 'A' - no LSD.  If it ends in a 'B' LSD.
I double checked with other sources.  Spit is correct (of course).
Then I looked at my Vin plate.  It's a B.  So I have the low ratio JDM box with LSD.  Rocking horse do-do!
I got so lucky buying this car.

I haven't quite managed to find out if my spare is a JDM box - I have an import box with LSD with C50k stamped on the box but C60 on the bellhousing.
I bought it from someone who did have an import but don't know the vin plate numbers and don't know the history of it.

I'd love to find out if anyone has managed to check the stamps.

cheers

You need the vin plate numbers to be sure. If the car came from Japan, there's a pretty fair chance it is a JDM box, unless it was replaced.
