Phixius Posted May 28, 2012 Author Report Share Posted May 28, 2012 I could have had my L20 and 5sp in my 521 by now, but my curousity got the best of me about the trannies... alll i was trying to get at was, what woud be a good tranny for my setup. Ive got 3.89 rear end in my 521 with 215/40/17 on a 8" rim Quote Link to comment
datzenmike Posted May 28, 2012 Report Share Posted May 28, 2012 I've also asked elsewhere about internal differences besides the synchros like bearings and whatnot. For now it's just the Porsche ones. And thanks for the compliment. Quote Link to comment

datzenmike Posted May 30, 2012 Report Share Posted May 30, 2012 Nice!! Moar pictures. Front counter bearing, 5th/reverse.... anything. Maybe there are other differences. Here's my '85 CA18ET 5 speed. It's still an FS5W71B with bronze synchros. Quote Link to comment

datzenmike Posted May 31, 2012 Report Share Posted May 31, 2012 Thank-you very much. If we ever get together I owe you a beer. Nice pictures. Quote Link to comment
Phixius Posted May 31, 2012 Author Report Share Posted May 31, 2012 Well im glad the pictures are sufficient, because right after i uploaded those pics, I reassembled it...needd to clean up and get back to my swap. Think I should run this in the truck or my other 5spd? I remember driving the 510 with it and it felt solid, short throws for a datsun or is that just how 280 trans are? Edit: Any idea on what its worth? Quote Link to comment
jrock4224 Posted June 1, 2012 Report Share Posted June 1, 2012 watch out ...franks taste in beer is both delectable and expensive...nice tranny dood Quote Link to comment
datzenmike Posted June 2, 2012 Report Share Posted June 2, 2012 It will work just as well as a wrecking yard 5 speed from an early 280z or 620 so I doubt the average person is going to spend much on it. If you can find a Z car owner who races his car you might get a bite. This would last longer between rebuilds than the stock 5 speed. The only down side is the wide ratios ... same as the stock 5 speed. Contact Nissan or Nissan Motorsports and ask them what they sold for new or if they know what they sold for used. Maybe they can put you in contact with someone who knows a lot more about them than me. A new from Nissan FS5W71B for a 620 with the same ratio gears as you have is $2296. I would have to assume a new competition box would be more. I would just keep it and use it. What the hell. Quote Link to comment
Phixius Posted June 2, 2012 Author Report Share Posted June 2, 2012 Since this tranny has a direct drive shaft, I thought I would fill it up with some fluids before I shove it in the truck. Found out you can just peek into the transmission fill hole and see the syncros... Comp tranny, steel... normal tranny, bronze... Also the fill holes are on opposite sides and the comp one is a little higher ( more capacity?) Quote Link to comment
ggzilla Posted June 2, 2012 Report Share Posted June 2, 2012 Stock factory Nissan transmissions can have steel synchros, that does not specifically make it a competition gearbox. The true competition boxes have special gear ratios as well as steel synchros. The lube capacity is the same FS5W71B and FS5C71B. Quote Link to comment
datzenmike Posted June 2, 2012 Report Share Posted June 2, 2012 Trucks tend to have the hole on the left and z car's are on the right but this is not any way to ID a transmission. I've just found it this way. After 40 years lots of different transmissions have been swapped into lots of different vehicles. The 5 speed in my 710 right now has an '85 diesel tailstock on it. Before that it was in my '78 truck for several years and before that I found it in a '79 280zx in a jumk yard and it looked like an excavator had driven over it. Quote Link to comment
Phixius Posted June 2, 2012 Author Report Share Posted June 2, 2012 I found this to be a good read. http://www.classiczc...hread20792.html and this -- http://www.classiczc...hread21549.html Your right ggzilla, ssems that some roadsters have them. and all have them in 5th. heres a post i found to be useful... I agree that there is lots of confusion - but as to Datsun Competition use of the term "Competition" applied to the transmission options - I do not believe what you have outlined was really the case. The Datsun Competition Dept. here in the US used the term "Competition 5sd." to differentiate the FS5C71B transmissions from the standard F4W71B and later the FS5W71B available in the 1977 and forward 280Z/ZX's in North America. The 4spd. F4W71B and the Overdrive 5spd. FS5W71B, that was optional in the 77+ 280Z/and standard in ZX came with wide ratio gears and utilized the Warner type synchronizers. The "Overdrive Competition 5spd." (FS5C71B) utilized the Servo type synchronizers and was offered in either Wide or Close ratios: Wide Ratio: #32010-N3200 1st - 3.321, 2nd-2.077, 3rd-1.308, 4th-1.00, 5th- 0.864 Close Ratio: #32010-N3030 1st-2.906, 2nd-1.902, 3rd-1.308, 4th-1.00, 5th- 0.864 Datsun Competition also offered a "Direct Drive 5spd" with 5th gear being a 1:1 ratio. The F5C71B These were referred to as the "Racing Transmissions" by Datsun Competition, and were offered with four different gear sets. Race Transmission #1: #32010-N3220 1st-2.818, 2nd-1.973, 3rd-1.470, 4th-1.192, 5th-1.00 Race Transmission #2: #32010-N3221 1st-2.348, 2nd-1/601, 3rd-1.296, 4th-1.138, 5th-1.00 Race Transmission #3: #32010-N3222 1st-2.192, 2nd-1.601, 3rd-1.470, 4th-1.138, 5th-1.00 Rally Transmission: #32010-N3201 1st-3.321, 2nd-2.270, 3rd-1.601, 4th-1.240, 5th-1.00 So here in the US - per Datsun Competition's use of the terms: Competition 5spd = overdrive with servo (steel) synchronizers) FS5C71B Racing 5spd = direct drive with servo (steel) synchronizers) F5C71B A side note just for fun: The "Warner" type synchronizers are brass, the servo (aka Porsche type) synchronizers are steel. The Warner type provide smoother shifting - the steel synchronizers wear longer, and they will take higher RPM. Porsche actually licensed their synchronizers from Warner the Patient Holder.. then modified the design to use steel. The extended shift linkage length, in the Porsches put additional and constant pressure on the synchronizers in their transmissions (kind of like riding around with your hand resting on our shift levers), causing the brass to wear prematurely, so a design change to steel was required.

datzenmike Posted June 2, 2012 Report Share Posted June 2, 2012 Yes I've seen that and it's very good. You probably have.... The .... Overdrive 5spd. FS5W71B, that was optional in the 77+ 280Z/and standard in ZX came with wide ratio gears and utilized the Warner type synchronizers. The "Overdrive Competition 5spd." (FS5C71B) utilized the Servo type synchronizers and was offered in either Wide or Close ratios: Wide Ratio: #32010-N3200 1st - 3.321, 2nd-2.077, 3rd-1.308, 4th-1.00, 5th- 0.864 Quote Link to comment
ggzilla Posted June 2, 2012 Report Share Posted June 2, 2012 I don't follow. If he probably has the optional in the 77+ 280Z/and standard in ZX that has W synchros, then why does it have S synchros? Maybe a previous owners installed them? Quote Link to comment
datzenmike Posted June 3, 2012 Report Share Posted June 3, 2012 What they mean is the 5 speed was optional starting in '77. They only came with Warner synchros. The overdrive competition FS5C71B (not sure but available through Nissan motorsports) has steel ones. Quote Link to comment
