T5
#4
ive got an 87 NA trans sitting on a pallet, its got good seals and didnt grind, pop or whine in any gear at any speed, needs the fluid changed though, but still has all the sensors still attached. LMK.

I have a T5 in great condition. I replaced the shifter with one from a Mustang so it's nice and tight. I also have a balanced driveshaft for the S30 with R200swap.

Nissan used two different transmissions during the production of the S12. The FS5W71B (also known as the "B" transmission) was used from 1984 - early 1986. The FS5W71C (also known as the "C" transmission) was used from late 1986 - 1988.
The "B" transmission was a leftover from Nissan's 1970's vehicles. It was used in RWD Datsun applications like the 280Z, the 620 Trucks and the S110 200SX. It was designed to handle horsepower, but not a lot, although it has worked reliably for some people in higher than stock power levels. The design used an external shifter linkage and a smaller casing for the reduced size of the gears inside.
The "C" transmission was implemented in the MKI to MKII crossover period in late 1986. This transmission was designed in the early 80's to be the non-turbo 300ZX transmission. It featured an internal gear linkage and stronger gears to hold the added horsepower of the 300ZX's VG30E. In late 1986, Nissan adapted the FS5W71C to fit the CA20E and the CA18ET, and phased out the old FS5W71B.
The FS5W71C lived a long life in Nissan's lineup. When the S12 and the Z31 were cancelled, the transmission was adapted to the KA24 engine and was used all the way through the 240SX production up until 1998, and then continued on after that in the Xterra until 2002. This means any short shifter made for a 240SX will also work in your "C" transmission equipped S12.
People in the 300ZX world have been having troubles with the Borg-Warner transmission that came on the early 300ZX turbo. The Borg-Warner was supposed to be "bulletproof", but apparently it's junk. They have found that switching to the non-turbo's FS5W71C tranny has been stronger and lasted longer than the Borg-Warner, even though it was designed for less power. It's a testament to Nissan's designs and quality control.

The B trans was used from '77-'83. The C trans was used with the '84-'88 V6n/a motors. The T-5 was used on '82-'83 L28 turbo motors and a slightly different version for the '84-'86 (FS5R90A) and (FS5R30A) for '87-'88 turbo cars. The early T5 was a NWC (non world class) and later WC (world class). The WC trannys were used in the Mustang 5.0 and some of the Camaros up to the mid '90s. The only weak spot on the NWC is the shifter that comes apart after 10 years of hard shifting. The NWC and WC shifters are interchangable. The T5 is good for 300+ whp. In adition the T5 has a lower first gear to help the turbo spool up faster.
You can find a B trans at the junk yard for $100 and take your chances. My T-5 and driveshaft is $400 plus shipping.

The driveshaft has to have the T-5 yoke on one end and the R200 yoke on the other. It is a combo of the zxt and z drive shafts, cut, welded and balanced. It can also be made from a ZXT driveshaft, shortened and use the pinion yoke from a zxt R200. The 2+2 shaft can be used for a fence post or a 2+2.

Or i could always just find a 2+2 turbo. one question. will the T-5 bolt in/ or will i have to change the mounts

Will a tranny from a Z31 bolt up to an L28ET? If so I may take that route. Otherwise I'll have to get my hands on a T5 again as well.
#16
i want it mainly for it being stronger. and a short throw. i won't be leaving the power range of the N/A though.

I took my 2seater T5 driveshaft to a local driveshaft shop & had them lengthen & balance it for ~$100.
I swear there had to be some 2+2 turbos w/ the T5... I saw a T5 2+2 driveshaft on ebay right after I had it lengthened. But I've never seen one in person.... my spare 82T 2+2 is AT... Now I gotta search it out.

Why yes... I think 2+2 turbos did have a T5 option ( http://www.cardomain.com/ride/2464414 ). I don't know if he swapped it in, but the motor sounds stock:

It wouldn't surprise me if most of the people who bought the 280ZX 2+2s bought them for the backseat and the fact that they could have their sports car while being able to seat the children. I'd also go as far to say as that person either didn't know how to drive a stick or it was purchased in auto so their spouse could? That's my best guess.
Although just in general it seems like it's hard to get a hold of a 280ZXT with a 5-speed.
