Ka 5 speed and 280zx 5 speed length difference??

[Lozer]

Anyone out there know if there is a difference in the length between these?

 

Im doing my ka swap and wondering if I will need to get a new driveshaft cut.

[EastBay521]

you do have to get it cut. I forget how much though

[datzenmike]

There are the shorter 71C from the D-21 Hardbody around 30-32" and then there's the 71Cs from the 240sx which are 34"???inches long. I would love to have one to measure. 

 

The zx 5 speed is 31.5" long.

The d21 tranny is about an inch to inch and a half longer than a dogleg

[datzenmike]

Assume the N American dogleg as there are imported ones out there that are the same length as the 71B. I have one. This would make the D21 about 27 to 27 1/2" long then. I would have thought closer to 30".

The d21 tranny is about an inch to inch and a half longer than a 1977 datsun s10 200sx dogleg 5 speed transmission

I'll measure it again for ya tomorrow, looking at pics I can't decide if that's the total length now or if that's just how much farther back the tranny mount is

[jesusno2]

240 trannys are really long. Im using a D21 trans in my 210 and the shifter was almost in the same spot as the stock A series 5spd. I measure the 240 ka trans once i forgot how long it was for some reason i remember the 240 shifter being like 9 inches farther back than the A series.

Tranny measurements. .. (mine, so maybe to spot on, but damn close.)

Bell to dust shield..
S14 KA -- 33 1/2"
Longtail (L) 5spd -- 31 1/4"
Track KA/Z24 30 1/2"

Bell to output shafts
S14 KA -- 33 5/16"
Longtail 5spd (L) -- 31 1/2"
Truck KA/Z24 -- 29 15/16"

Shifter hole location
S14 KA -- 31 1/2"
Longtail 5spd (L) -- 29"
Truck KA/Z24 -- 26"

 

 

​I should go back a measure with a straight edge...

The truck trans, I'm assuming that's a d21 2wd?

YES!!! The 71B is precisely 31.5". Stand the tranny up on two chunks of 2x4. Place a straight edge across the output and measure down vertically to the front edge of the bell. Tape must be parallel with the center line of the transmission. A sloping measurement is always longer.

[Phixius]

Ok. Straight edge. And removed dust shield...

 

S14 ka -- 33 5/16. Shaft sunk in 1/8. 33 3/16 for shaft.

 

Ka D21 and 720 z24? -- 28 9/16. Also 1/8 sunk in for shaft. 28 7/16.

 

[datzenmike]

Dude........ t/y.

[scooter]

your on it! good job phixius, how does the bell to tranny mount distance on the d21 tranny look like vs the z 5 speed?

 

if we have the tranny mount distances on here we could pin this maybe?

[]2eDeYe]

Very nice! Now how about bell to transmission mount center line? :D

[Phixius]

Well, aren't you guys a needy bunch...

 

 

Bell to trans mount center line..

 

L 5spd -- 21"

S14 -- 22 1/4"

2wd truck ka -- 22 1/8"

 

There is some wiggle room with the mounts. They have big holes. Didn't take the s14 mount off, so they might be the same.
