ITR gearing?

[driftburger]

What syncros are different in an ITR tranny? 1st and 5th? or is it every gear?

Are you just thinking up random questions?

[gunther]

seems like an acceptable question...

So does that make 2 people here with a typeR trans waiting to be rebuilt? Just a funny question because ive never heard that or thought about it.

I have a turbo LS. 1st gear is a little too long on the stock LS tranny and was looking into the shorter type-r gearing. Instead of buying an actual type-r tranny I was looking into the type-r syncros since im building up a GS-R tranny for next race season. Im trying to clarify the differences in gearing.

I found the differences. Here's the exact gearing on the trannys. It looks like everything but 1st gear is different. Complete opposite from what I was thinking.

S80/Y80 (USDM B18B1)
1st 3.230
2nd 1.900
3rd 1.269
4th 0.966
5th 0.714
FD 4.266

S80 (USDM B18C5 W/LSD)
1st 3.230
2nd 2.105
3rd 1.458
4th 1.107
5th 0.848
FD 4.400

Much bigger differences than I would ever expect...
