280zbeeT Posted March 31, 2011 Share Posted March 31, 2011 so I can buy a very Nice z31 ACT clutch for $80, and I was wondering, with my current setup, turbo built engine, I have a 240sx transmission swap with a n42 block.. can I use this z31 clutch?? or is it out of the question?

LanceVance Posted March 31, 2011 Share Posted March 31, 2011 Might want to give the specifics of your flywheel as well. How hard was the gearbox swap if you don't mind me asking? I'm planning the same set up (Turbo w/ N42 Block, 240sx gearbox). Quote Link to comment Share on other sites More sharing options...
280zbeeT Posted March 31, 2011 Author Share Posted March 31, 2011 (edited) all i know So far is its a (84-89)ACT 300zx clutch I googled that clutch and I can Only find an ACT z31 clutch for that year as a 240mm clutch.. so Im guessing thats what Im looking at buying, would that fit? it was really easy cus I bought the car with the 240sx tranny swap, when that tranny blew I just bought another 240sx tranny and swapped the bellhousing, the custom driveshaft and ujoints were already there.. all I know right now is its a z31 clutch Im waiting to hear back which model and type of z31 clutch it is, (turbo, mm etc.) Edited March 31, 2011 by 280zbeeT Quote Link to comment Share on other sites More sharing options...
280zbeeT Posted March 31, 2011 Author Share Posted March 31, 2011 (edited) http://www.andysautosport.com/nissan/1984_1989_300zx/transmission/clutch_kits/act/actp00062305.html this is what the clutch looks like, and the only clutch I can find for the model and year so Im guessing that the 240mm is correct. hey, I also found this. it says it fits a 280zx, but does that mean it Wont fit a n42 block which is from a 76 280z? since I have the 240sx tranny? http://www.thezstore.com/page/TZS/PROD/PCC08/21-2274 it says, "Model Guide: 240mm Datsun 280ZX, Nissan 300ZX Model Restrictions: Fits all 79-83 280ZX 2+2, all 81-83 280ZX Turbo, and all 84-89 300ZX Non Turbo. Code Guide: Datsun S130, Nissan Z31 Year Guide: 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989 " hey I also found this.. The second strongest Z31 manual transmission is the FS5W71C found in any 5 speed non turbo Z31. This transmission is internally the same as the transmission used in the 240SX, 180SX, Silvia, etc. A few people who have blown up their FS5R90As have swapped to the Z31's FS5W71C transmission and not had problems. A lot of 240SX owners have the 240SX version of this transmission mated to their SR20DETs and KA24DETs running 400+ hp with no problems. Any short throw shifter made for the 240SX (S12, S13, S14, S15) will fit perfectly in this transmission. does that mean go for it, the clutch will fit?

280zbeeT Posted March 31, 2011 Author Share Posted March 31, 2011 okay so Im kind of figuring this stuff out, I believe the z31 clutch will fit, but I need a 240mm flywheel in order to make this work right? now a 240mm flywheel would fit my n42 block right? then I can use the z31 clutch?
