findmuck Posted December 15, 2014 Report Share Posted December 15, 2014 Did my research. Have found nothing. Just curious if a 5 speed from a 1991 KA will bolt right into a 1990 KA? Are they the same transmissions? Quote Link to comment
Fat510 Posted December 15, 2014 Report Share Posted December 15, 2014 yes, the KA24E and DE use the same tranny in the 240sx 1 Quote Link to comment
EastBay521 Posted December 16, 2014 Report Share Posted December 16, 2014 same gearing? Quote Link to comment
q-tip Posted December 16, 2014 Report Share Posted December 16, 2014 I think the only difference is the engine being single cam or twin cam. Quote Link to comment
findmuck Posted December 16, 2014 Author Report Share Posted December 16, 2014 I think the only difference is the engine being single cam or twin cam. But that would change the size of the flywheel or anything right? Quote Link to comment
Fat510 Posted December 17, 2014 Report Share Posted December 17, 2014 I don't think so. I think you may have to change it and/or the clutch when you changeover from a truck tranny to a car tranny or vice versa but I'm not 100% Quote Link to comment
q-tip Posted December 17, 2014 Report Share Posted December 17, 2014 It should be the same, where is dmike to weigh in on this? :lol: Quote Link to comment
datzenmike Posted December 17, 2014 Report Share Posted December 17, 2014 Did my research. Have found nothing. Just curious if a 5 speed from a 1991 KA will bolt right into a 1990 KA? Are they the same transmissions? The transmissions are likely identical and length will be the deciding factor. Same length? no problem. As long as they bolt together, transmissions don't know or care what drives them. Engines (with clutched and flywheels) don't care what they are driving. One does not affect the other. The KA24E and KA24DE apparently both use a 225mm clutch/pressure plate and flywheel. The flywheels are the same part numbers but the clutches are not. At least not exactly... So Bolt the '91 DE 5 speed onto the '90 E engine, but because the release bearing collars are matched to the clutch put the E collar (and a new release bearing) onto the DE 5 speed. The release collars appear to be the same part number but why chance it? Keep the collar with the engine it came on. 1 Quote Link to comment
Elkie Posted December 17, 2014 Report Share Posted December 17, 2014 Once stuck a 95 240sx tranny in a 97. Used a clutch kit for a 97 and T/O bearing for the 95 tranny, clutch wouldn't engage. Had to repull the tranny. Match the clutch and t/o to the tranny. Quote Link to comment
datzenmike Posted December 17, 2014 Report Share Posted December 17, 2014 No. (or you said it wrong) Transmission does not matter. The throw out collar must match the clutch. '97 clutch will need a '97 collar. Transmission can be anything that will fit the engine Quote Link to comment
Elkie Posted December 17, 2014 Report Share Posted December 17, 2014 So you would match the clutch and sleeve to the motor rather then tranny? I guess spline count would be the same on all of em, so you would be covered either way. Quote Link to comment
datzenmike Posted December 17, 2014 Report Share Posted December 17, 2014 Collar is only matched to the pressure plate. The pressure plate can only bolt to a flywheel that has a matching bolt pattern for it. Engine does not matter either but naturally the flywheel must fit it. The 240mm pressure plate and flywheel comes only on the Z24 engine in the 720. That flywheel will bolt to an old L20B so (and I have seen this) you can have a 240mm clutch on an L20B but it will only work with a collar from a Z24. Quote Link to comment
Elkie Posted December 17, 2014 Report Share Posted December 17, 2014 lol, guess it boils down to flywheel then. Another example would be the white bunny setup for 240sx ka's to get 240mm clutch. Quote Link to comment
datzenmike Posted December 17, 2014 Report Share Posted December 17, 2014 Yes, this is all I have ever read about on 240s. Always thought they were all 240mm but just a good 225. Takes a lot to hold back 150 hp.I have a couple of 720 240mm wheels and would like to run this clutch on a 2.3 engine I'm building. 1 Quote Link to comment
