Real quick question....

Ok well after reading many diff. pages on transmissions and gear ratios etc. It seems my Non LSD Y21 trans is more or less a weaker version of the US spec trans. After reading around I noticed that the LS and ITR share the same Final drive ratio.... 4.400 so does this mean I can put the LS finally drive in my SIR trans when i rebuild it? Woudl this even help or be worth the trouble if the FD was free? What about the diff gear of the LS is it the same...as the US ITR trans?


Just something to ponder?

Assuming the gears themelves on my sir trans are good just grindin a lil no I can just get new brass synchros and be done with the rebuild right?

should work with some grinding I would think. a gear is a gear, as long as it fits.

The B16 tranny you have should have the exact same gear ratios as either the USDM ITR tranny or 96 spec JDM ITR tranny, including the final drive. The only real differences are the LSD, and the multiple synchros present in the actual R tranny's.

The LSD and the final drive is the only diff. between my SIR trans and an US ITR.

I secured an LS final drive and pinion ring (ring gear bolted to the diff/spider gears) and it is a 4.40 just like the US ITR so now the only diff is the lack of LSD

hydro ls has always been 4.26. your SIR tranny should have a 4.40 already. i got a cusco lsd if you are interested for ls/b16 diffs.

if you plan to use a R lsd, then just use that along with a R ring gear or gsr ring. don't change anything with your shafts and leave your stacks alone. note*pinion is the smaller gear that turns the ring...the bottom gear on the countershaft.
