...Hi...

LS tramission GSR DIFF HELP
Well, this isn't all confirmed yet but my builder has my transmission & was getting a LSD diff installed because my stock one broke. Basically without getting into a long story, I thought I had a GSR tranny & he's saying its a LS but someone put an GSR Diff in it which we all know shouldn't be there. I simply, for right now need to know if a GSR Diff can fit into a LS or rather can a LS ring gear fit onto a GSR diff. He is saying that he counted the teeth "64/15=4.2666 ratio", which is an LS FD but correct me if i'm wrong but I thought a LS FD cannot fit onto a GSR Diff. Isn't the LS diff physically smaller & the ring gear wouldn't swap over to a gsr?

...Hi...

Ok nevermind that I guess, assuming now I have a straight up LS transmission & I have a GSR LSD that I bought assuming it was a GSR tranny...if I still wanted to use the GSR LSD I would need to get a whole FD kit from a ITR/GSR/CTR? What do I need & lastly, how do you think a LS tranny with a JDM ITR 98 spec 4.78 FD do with LS gears? I'm building a poor man's type r at the moment. Will it still fall out of vtec when you switch gears drastically?

It may... I don't know where the LS transmission falls in terms of RPM per gear. The final drive won't change the operating range of your engine in each gear- that will remain the same. It will only change the speed range of each gear.

...Hi...
|
What your saying is, essentially i'll still have the longer gears but my engine will be at a higher rpm say when I switch gears or cruising speeds. Its hard to explain what I think your saying but I get the basics. I have a B16 Transmission from my del sol as we speak & would love to use that but i'm going to be making close to or over 200whp after tuning & I don't feel too confident in the stock differntial. Does anyone know what exactly I would need in order to use my GSR LSD on my B16 transmission? ITR/GSR FD, so on...?

The stock diff will be fine at 200whp.
It's hard for me to explain ratios on a forum, but make yourself a spreadsheet with different gear reductions vs engine speeds and driveshaft outputs and you'll get the idea. __________________
