therein lies my dilemma, as I'm doing a b13 w/ a non-lsd trans and I know of no sr b13s that were lacking lsd. someone in another thread mentioned using a b15 axle, so I guess we'll see when I put it all together.

It's easy, just use axles from one of the following vehicles:

1998 200SX SE-R
1998 Sentra SE
1999 Sentra SE

OK,
kinda wierd, but here goes: We were counting teeth on the ring gears. Now for obvious reasons you cannot use the 4.18 1.8 ring gears because LSD and nonLSD aren't compatible, but the teeth count between the B13 2.0 and the B15 1.8 were the same. So we figured the b13 2.0 would be fine. Wrong! the teeth are cut different, so it wouldn't work. So we looked at the previously overlooked B15 2.0 ring gear, and the ring gear is the same teeth count as the 1.8, just the shaft teeth count is different. So that looks like it will go in fine and still be 4.18.
Now for the New Stuff:
I am going to be mounting a 250mm clutch. JWT has a clutch designed for the FI Zs that has a 1200kg clamp force. The JWT flywheels are now being double drilled for this size. So I am going to be mounting the RWD SR20DET flywheel with the 250mm 1200kg clutch kit. The t/o bearing needs to be changed, the starter must be the no nose cone starter, and there is some grinding to be done. Oh yeah, and you have to leave some bolt out. But they're doing that anyway in some of the new trannys. So that's basically it. maybe done by tomorrow.

But If YOu have a P11 VE can you bolt it up to a 93-97 SR20DE LSD Trans or you have to buy a B15 SE 2.0l Transmission? What Transmission is better.

Maddnismo

Sorry after this 7 pg posting I was confused, you guys lost me real good

I have a B14 200SX with a 1.6l Engine I bought the SR20VE Engine And I dont have a clue what transmission , axles, that I need for this engine (97 SR20ve)

My GOD Please Help


P.S.> Also , while I 'm here let me ask, Does anyone do wiring harness plug and play swaps for SR20de to SR20VE, just for the sake of not having to cut off the wires, fine out how they match up (color codes) then tape them back.

Slow 96R

Since you have a B14 just use the transmission and axles from a 95-97 SER. Even if you decide to get the B15 trans you will still use the same axles.

Joel is right. Use the tranny from a 2.0. If you use a B13 or the 95-97 B14 you get the LSD. The 98-99 B14 doesn't have LSD. The B15 or P11 can be either way. Two things:
1. The axles must match the dif.
2. If you put the B15 or P11 into the car, it will have to be converted to cable operated clutch.

Does anyone know the number that identifies the P11 or B15 VLSD tranny? I haven't seen anyone post them anywhere.

I do not believe there is any # to identify them stamped on the case. You have to simply identify them by looking at them. As Dre Miko taught me, "If the seals for the axles on both sides of the transmission are the same size it is not an LSD trans. The side with the hump must be visually larger than the side with the gear shaft sticking out. Like comparing a nickle to a dime in difference." Any questions??????? GTIRoids

GregV

Look for the big seal.

Thanks for the info. I may have found a JPN P11 tranny here http://www.sr20forum.com/sr20de-technical-corner/112824-p11-vlsd-tranny.html (picture included) but I'm still not sure. I don't want to take over the thread with my questions so if any of you in the know could visit my other thread and help me out I'd be very grateful.

Thanks.

Ok so the part number for the P11 locking differential tranny is RS5F32V correct?

well thats the number for the B13/P10 and B14 LSD too. I think its more of a model number than a part #, but basically the V stands for VLSD... if it has an A at the end it is not VLSD....

I searched all over the trans for a part number but never found it.

So with all this in mind where is the real proof that the trannies are different from eachother as far as gear ratios and strength? Why would the numbers be the same from the B13/P10, B14, P11 and B15? Wouldnt they change the numbers to identify different trannies? As far as P10, P11 vs. B13, B14, B15 why would the gear ratios be different when they are being powered by the same SR20DE motor? What exactly would that accomplish from car model to car model?

hpro123

For gear rations what exactly would a "real proof" be? They are quoted as different in Nisssan tehck literature, they feel different when you drive them, they are different according to several people who have opened them and counted the teeth..

For strength there can never be a "real proof"... Unless someone tests them all to the point of failure in a controlled laboratory environemtn.
Maybe they should but as long as it is the same basic design there is no point in it. Their parts programs (Fast) can identify different trannies with a unique part #. Same way as they identify all the millions of SR20DE(T)s ever made in different configurations... After all, they are also called SR20DE(T) . All fo them.
There are a mutlitude of factors here.

Different car weights. In a heavier car you probalby need to space the gears differently to take advantage of the power curve. Differnrt engine power curve. Prime example here? Primera P10 tranny on a SR20VE. It is so long it never lets you get in the powerband and stay there between shifts with the stock 7200rpm rev limiter.

Different "image" the car needs to have. A sporty 3d hatchback version may need shorter gearing to feel... well, sporty! Same engine on a larger 4-door sedan that is advertised as a comfortable, quite car to travel in would have much longer gearing.

Etc., etc....

If you ever took one apart you would know.

CowboyDren

Just hit car-part.com and look for a few B15 or P11 transmissions. In no time at all, you'll find a listing for "RS5F70V," which is the same model number that's printed in nissannews.com's archives of same vehicles. I also wrote an extensive post comparing gear ratios a couple of years ago (I *think* I put it on this board...). You just need to look a little harder next time.

Wait, no, it doesn't look to be on the new copy of nissannews.com's site. It was on the old one, though. And it's on every model info panel of thusly equipped Nissans.

Ok guys, I need your help. This might sound dumb but am not really sure of the answer. Here it is: I have a 92 classic and did a Pulsar GTi-R swap and used my B13 tranny from my original motor. That tranny / clutch is now shot. I ordered a B15 tranny w/ vlsd from a 2001 Sentra SE and finally came in. I am going to go ahead and order a clutch kit for it. My question is, which clutch kit do I order for? Should I order one for a 1992 se-r or should I order a clutch kit for a 2001 Sentra SE or could they be the same application meaning the part# would be the same for 1991 to 2001? Please help
