FS5W71B trannys-- SOLD

Post by SteveEdmonton » 01 Jun 2019 09:38

Two close-ratio (yes, really) FS5W71B trannys. Both are complete but in unknown condition. $125 USD or $150 CAD each. Delivery to Greater Vancouver area is possible around June 10-- contact me for details.

#1 is from 1981-1983 280ZX. First-gear ratio = 3.062; fifth = 0.745. The bellhousing has been switched-- not L-series but from apparently from an SR motor. HOWEVER, I have an L-series 4-speed from a Z-car that you can have for free. Put that bellhousing together with this rear case, and you're off an running. (No photos of the 4-speed-- can't add any more pictures into this listing, but contact me if you want me to send you some by email.) SOLD

Note the similarities...

This is not an L or Z series bell housing. Probably from an SR20, not a VG but definitely NOT L or Z series. The rear half is from an '80 to 86.5 71B.

Both rear cases are from an EFI car and not a truck. So 280zx, 200sx or 810 Maxima.

This isn't a '79zx 5 speed, the rear case is wrong and it would be a mid ratio, but it is consistent with being an '80-'83 280zx non turbo 5 speed. If it's an '80, the over drive is 0.773. If '81-'83 it's 0.745. I you place in 5th gear and place an old clutch disc on the input spline (to make turning it easier) and mark it and the output spline at 12 oclock. Have someone count the output turns while you turn input exactly 20 turns.

If you get 15 turns it's a 0.773. If you get 15.5 it's a 0.745. This is the only definitive way to tell is from a 280zx. If you get a higher number like 17 it's a mid ratio box from an 810 or Maxima.

Thanks for the info about the front case of the first tranny, Mike. I was obviously misinformed by the guy I got it from! I've corrected the ad accordingly.

The ratios I reported for both trannys are correct, determined by exactly the method you describe.

And regarding the year of the second tranny, I said '79-80 because of info I gleaned from a chart by Marc Sayer, which says the 0.773 ratio was manufactured from 8/79 to 6/80. I guess that probably does make it a 1980 model year, as you say.

Finally, I've called both of these "close ratio" trannys on the basis of a post that you yourself wrote a few years ago, in which you call a first-gear ratio of 3.592 "wide," 3.321 "medium," and 3.062 "close"-- http://the510realm.com/viewtopic.php?f= ... ng+rod+2.1

Thanks for chiming in, as always. You certainly do know these transmissions!

I go by the model year which begins around June/July of the previous year. This is the car they would normally be in. Confusing, I know.

I have a '79 280zx in my 710 and for sure, it's a mid ratio with a 12% over drive. I do have an '81-'83 zx laying around somewhere but hesitate to go to the bother of trying it because of the really tall over drive they have. Right now 5th is like another gear and it pulls really well in it with 4.11s. I'm afraid an almost 25% over drive will be for cruise only. Now in a 2,200 pound 510 (maybe with an L20B or larger) that would be different.

Note updated detail in the ad-- if anybody wants to buy the remaining FS5W71B, I'll toss in a 240/60/80Z four-speed with an L-series bellhousing. Match them up and you're off and running.
