Thread: Transmission list?

I thought I saw one somewhere but after searching and looking through the manifesto, I can't seem to find a list of compatible transmissions and their levels of greatness. I am about to start mild turbo build and I would like to source out the best trans I can find at a junk yard. I will also add that the tapatalk search function pretty much sucks.... Thanks in advance for any links or info.

you mean this:
Trans worksheet

Also has in there the different threads that have trans informtion (no links you will have to search). Sourcing straight from the JY would probably be a P11. My understanding is it's more dependable.

Sweet! Thanks man. I definitely didn't come across that thread. And just to clarify... P11 is 95-99 g20??

yes, and if you can't find one of those (don't know why you wouldn't) next in line is the B14. I would also keep an eye on the FS section. A couple people (mainly Andreas) have come across 20V 6 speeds which can go in it without having to open the case. You do need a lot of parts and will loose the hubs you currently have, but much more efficent trans.

P11 or B15, either one. And you want one with an LSD.

From what I *understand* the B15 is preferred for NA, the P11 for turbo applications.

Let me raid the Technical Information Library, and the Tech Section of the respective SR20 forums....

Hope that helps.

The B14 had a *hotly debated* half-assed *fix* from Nissan that *probably* makes it better than a B13. BenFenner and I have gone round-and-round about it. I call it a wuss band-aid because Nissan knew the B13 tranny sucked and should have been re-called. Ben (who is faaar more mechanically minded than me) thinks it is a pretty good fix. However, there have definitely been some B14 transmissions (and late model B13 trannys, after the supposed "fix") that develop 5th-gear pop-out. I will concede that a B14 tranny is still probably lower mileage, and a better bet than a B13 transmission. I would not waste my time with either a B13 or B14 tranny ever again. YMMV.

no ..they still have the old casings ..you'll need 00-02 trans

Like was said. The P11 or B15 transmissions are your best bet for a 5-spd swap. For Turbo application you best bet, gearing wise, would be a '99 P11 trans. However, the '00-'02 P11 transmission is slightly stronger than the '99. For a mild turbo I would look no further then a '00-'02 P11 (G20t) 5-spd LSD trans. This trans has shorter 1st and 2nd gears but should be fine for a mild turbo set-up.

Thanks guys. I knew about the 6 speed swap, but I just don't want the added hassle of that swap. 99 p11 it is. Now I just have to find one.

@BenFenner should add this to the manifesto if it hasn't been already...

@BenFenner @Cliff

Hell, add all those threads that I posted above to the Manifesto. Only a few of them (?) are in the Manifesto yet. If the Manifesto is basically a "Table of Contents" or Directory, then those threads I posted should be in there.

2 cents.
