Deas anybody have any info on JDM Turbo automatic FC differentials? They were offered only in Japan and I have trouble finding info on them. Is differential ratio the same as n/a automatic (3.9) or different? Also I need to know if jdm turbo automatic is the same as turbo diff in USA/EU and takes turbo axles and driveshaft?

Thanks

 

i recently got a 91 JDM brochure and learned a bunch of stuff.

in Japan, the a/t got the same 4:10 as the manual. additionally every model except the GT-X had an open diff. the models go GT-R, GT-X, GT-Limited and GT-Limited special. the GT-R is a base model, comes with nothing, not even alloy wheels, the GT-X is very close to the US spec, except it has no sunroof and no ABS. the GT-limited is like our GXL, except it has ABS, and the GT-Limited special adds leather and CD. all models were available with a/t or m/t trans

 

Thanks for good info
