I'm parting out an 83 200SX with a 5 spd ans some sort of t-belt engine, will the trans work in anything else?

 

Also, not possible if stock. 1983 would be an S110 chassis, Z20E/Z22E engine (timing chain). 1984 would be an S12 chassis, CA20E engine (timing belt). 

 

CA trans only fits a CA. Z20/Z22 trans really only fits a Z20/Z22/Z24 engine, but can be used on an L in a pinch.

'82-.83 S110 200sx were Z22E engines. '84 and on S12 200sx had the CA18ET, CA20E and VG30E engines. The transmission is a direct bolt in, to the earlier '80-'81 S110 200sx and the '81-'86 gas engine 720 if you check the lengths.

Everything I said was for the 31.5" long FS5W71B transmission used on a Z series engine.

 

 

The D21 Hardbody truck 71C is (I think) slightly shorter than the 71B but might fit. The longer 71B may not fit where the 71C fit. Too tight? So the 71B will bolt to the Hardbody Z24 but may be a little long. In addition the 71B is a weaker transmission than the 71C.

 

The S13 and S14 car 71Cs were much longer and not even close.

 There were two CA 5 speeds, a wide used on the CA18ET and a mid ratio used on the CA20E but both have the much better 2nd to 3rd shift without the big RPM drop. Second is moved very slightly away from first and closer to third so the drop is less noticeable. (true the first/second now has a 5% increase in RPM drop but it's in the lower gears/speed and not as noticeable as the 2/3 shift at higher speeds) On the CA 5 speeds the 2/3 shift RPM drop is 33% (wide) 31% (mid) verses the 37% drop on all the previous wide and mid ratio transmissions.

 

 

 

Depends on the year CA, it's still a good 5 speed. Up to '86.5 (model year) it was a 71B. After '86.5 it was a 71C.

 

A 4 or 5 speed 71B front case and a new 56mm counter bearing will convert it to L series IF it's a 71B to begin with. After is problematic, but doable.

The first time I went to a factory Datsun school in Gardina in 1969 there where a lot of Datsun Auto Engineers running around the dyno room writing things down on their clip boards in their white lab coats, were you one of them? I'm impressed!

I have an '85 CA18ET 5 speed laying around. That's the wide ratio with the low 3.592 first gear and 62mm counter bearing. I counted the main and counter gears and confirmed them. I also have a spare L series front case for it..... some day....

 

Some of this stuff I heard about or researched it but can't always remember the exact numbers. But I know where to look for it. Some I wrote down and saved.  Have about 600+ 'tranny' related pictures.

FYI, it's just a matter of machining out one of the holes in the front half of the case for the larger shift rail. Done this a few times before to be able to use a KA/SR trans behind a turbo L-series...

Yes a 16mm hole where the 14mm was for the 1/2 shift rod. It also requires machining around the counter bearing area on the front case for clearance or risk pinching when the case bolts are tightened up.

FS5W71B case modified to take a 71C internal gears, 62mm counter bearing and 16mm 1/2 shift rod.

See that thin toothed wheel just behind the lower counter bearing and in front of the counter drive gear? I think this is an oil slinger to lube the two large bearings, can't see any other use for it. This will pinch the front case if it isn't clearanced. 71C gears are also wider (front to back) to increase strength so not much room left.

 

 

In the top picture near the 16mm hole... see that little J shape and the small hole. I think this and the front cover plate supply splash oil to the two front bearings through it.

 

71B and 71C front covers. See the extra slots added on the C?
