OK so what happens if you swap the B15 final drive for the B13 or P11 final drive. Would that increase the top end speed?

That would lower the maximum speed. But you cant just swap around final drives. You have to swap the pinoin gear that goes with that final drive or your tranmission will sound like an airplane.

OK these numbers seriously puzzle me as I am not sure what I should be looking at...

I have a b13 with a b15 se transmission...should I be looking at the b15 se numbers??

3rd gear topping out at 134.40 @ 7500RPM's sounds off a bit no??

Maybe I'm looking at the right sheet.

lmk!!

PM Stratton. He is selling a VE tranny.

is it possible to put a 6speed vspec tranny into any of the older cars?

So what's best for acceleration? B13 tranny?

I don't want to sound like a newb here, but i've been searching and i can't seem to find the answer to my question.

I blew my old b13 lsd tranny and got a p10 non-lsd tranny to replace it due to availability. i still have the old b13 tranny and i want the lsd back. i hate not having lsd. it's a major pita, especially in the snow.

what can i do to use the lsd in my old tranny? should i just swap over the p10 gear stacks to the b13 or the driverside case and lsd to the p10?

i'm not sure if there's a difference in the bell housing between the two, and i don't want to tear them both apart to find i wasted my time since it is my only car. any help is greatly appreciated. thanks, guys.

What blew on the b13??

I would swap the b13 lsd case and final drive over to the p10 transmission. you can only do this if the final drive ratios are the same. So p10 transmission have different final drives then b13s

Some GA16DE data to add to the mix

USDM GA16DE B13 FWD gearset:
1st: 3.3333
2nd: 1.955
3rd: 1.286
4th: 0.926
5th: 0.733

final drive: 3.895 (Sentra)
final drive: 4.471 (NX1600)

JDM GA16DE FWD gearset:
1st: 3.063
2nd: 1.826
3rd: 1.286
4th: 0.975
5th: 0.810

final drive: 4.167

On nissanforums they said apparently that JDM N13 and N14 have same final drive as NX1600, 4.471, but the N13 gearbox won't fit on our cars (you could still take the final drive gear to use in another box though).

For better low-end acceleration (from a stop, or hammering out of corners), which of the setups as-is would be best? I have the USDM GA tranny now, and I find it less than ideal, though fuel-efficient. Which one, an NX1600 or a JDM tranny, would be better? I dont care about top speed.

NxDET · Jun 19, 2008

Correct me if im wrong :

For best accel combo, it would be :

buy a b15 tranny, put b13 4-5 gears into the b15.

I think the gears in red mean the best accel or it means other words?

skcusloa · Jun 19, 2008

Those aren't right according to my b13. I've checked mine with gps and it's accurate. I'm doing aobut 80 at 4000rpm in 5th. 3200 is 65. I would have been pulled over a whole lot if that thing was right. Maybe it's tires? I don't know the circumferance of a 205/50/15....

JohnyFive · Jun 19, 2008

4000 rpms for me too is also exactly 80 mph in 5th, in my b13.

NxDET · Jun 20, 2008

b13 got 14inch tires oem...

NissanEgg · Jul 19, 2008

I have a 91 SE-R with B13 trans, and B14 SE-L wheels with 195/50R15 tires. At 65mph in 5th I am at around 3200rpm, and at 80mph in 5th I am around 4000rpm. 7500rpm in 3rd is about 89-91mph.

mercado se-r · Dec 4, 2008

how about the all wheel drive trans with transt=fer the gears fit a usd trannny or can they be interchange

Freek · Feb 18, 2009

Pretty much nothing is interchangeable between 4wd lsd and FWD non-lsd trannys.
I opened both tonight and gears/final drive count different and both parts of the housing are also different.
Sure you can swap certain parts, but you cant just switch out gearstacks or diffs.

Cliff · Oct 4, 2009

Would a moderator please contact me regarding this thread? The spreadsheets given do not contain the correct formulas, so the MPH calculations are off.

I re-created a spreadsheet/workbook given the correct diameters and circumferences, so that the MPH reports are consistent with OEM wheel/tire combos. This will give an accurate starting point for those wondering what's what. In addition, I provided a formula in my spreadsheet that will allow the individual to calculate their own tire diameter, which they can plug in and immediately see the change in MPH across the entire spreadsheet.

Thanks!

pakis · Jun 23, 2013

4000 rpms is 80mph for me is there something wrong with my tranny? I don't remember my old ser turning the engine that fast at 80mph
