What's happening. These are my questions? 1)I have TOYO 205-50-15's TS-1's which I know are not suited for the snow. For the winter I was going to put my steelies from my 91 Civic Si w/ 185-60-14's on since they are already mounted. I should be good to go as far as my speedo. I wont be driving my GS-R in the snow hopefully unless my Civic is in the shop.That'll be my snow car.
2) Just curious about LSD. Would I be able to bolt me a USDM TYPE-R Tranny up without any extra parts:axles etc... I know the gearing on the Type R is closer to the B16A1 specs than the GS-R. At 80 in the GS-R I'm at 4K RPM. So at 80 w/ the Type R tranny would my RPM's be higher. I know it will be pricey when I decide to. Now I know the JDM Type R tranny would problably cost more w/ LSD. Thanks

 

Your first Question is not a question. The ITR tranny should bolt up without problems if your GSR is 94+ and while your doing 80MPH your RPM's will be around 5500rpm's give or take.

 

The ITR tranny has an identical final drive ratio of 1: 4.400.
Fifth gear is a teensy bit taller in the ITR (0.848) compared to GSR (0.787)

I'm awful at math, but I would guesstimate that at 80mph, you're closer to 4500 rpm. h:

And we do have an ITR forum....you could always ask them.

BTW, I got my numbers from this thread. You might want to check it out sometime.

 

Yes, and ok.
