: Help sourcing B15 LSD tranny Wojtek1977 07-21-2009, 10:30 AM Hi guys, I was wondering if you know a place that is selling 2000-2001 Sentra SE w/pp 5spd LSD tranny as I am looking to give my VE a boost next season (B13 tranny is alright although I could use shorter gearing). Thanks.

Thanks. Wojtek If you want shorter gearing then the b15 isnt what you want. GregV 07-21-2009, 12:16 PM If you want shorter gearing then the b15 isnt what you want. Huh? Why would you even say that? The B15 is much shorter than the b13. 13% in 1st, 12% in 2nd. Please stick to commenting on what you know for sure. Wojtek, where in canada are you? I'm sure i can help you. I have sourced a few in canada, but typically they only want to deal with Canadians. Best yet, give me a call. adishere 07-21-2009, 01:43 PM how does the b15 compare to a 92 g20 lsd tranny, i like the gearing in my car right now nice and long,,,just wondering GregV 07-21-2009, 01:46 PM I don't have the specs for the 92. Do you know the gear ratios? adishere 07-24-2009, 01:18 PM I don't have the specs for the 92. Do you know the gear ratios? no not sure of the ratios, i really like how my car is geared almost dont wanna change up so hopefully dont break a tranny! are there different ratios from 91-94 on all the g20 lsds? FastNX 07-26-2009, 12:47 PM The B15 is much shorter than the b13. 13% in 1st, 12% in 2nd A few years ago we looked into running the B15 trans on our late VE powered race car. Although first and second are shorter on the B15, the other gears are so close to the B13 that it would make almost no difference on the track (you are rarely, if ever in 2nd on the track). If mempy serves me correctly, 3rd and 4th are the same, and 5th is slightly different. If you wanted shorter gearing, the better bet would be to do the Sunny 4.4:1 final drive in the B13 unit (if it's still available). GregV 07-26-2009, 07:19 PM The 4.44 is still available.
