Guest Anonymous Posted December 13, 2000 Share Posted December 13, 2000 Will the NisMo flywheel off my l28 engine fit and work fine on a l28t? Are the clutches the same dimensionally and whatnot? I see MSA has flywheel listed for s30 and s130 non turbo.... So I assume it'll fit and work fine, no? While I'm at it, my 77 5 speed transmission will fit correctly on a l28t block won't it? ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
jeromio Posted December 13, 2000 Share Posted December 13, 2000 Blocks are the same. The 82-83 turbo blocks have some differences internally, but everything else is the same. As far as I know (and been told), all the flywheels, clutches, etc. are interchangeable, except perhaps the T5. I bolted a 71 4speed, flywheel and corresponding clutch to a 83 NA motor. (I also bolted up the dual SU intake - pretty cool how the late model head has both sets of threaded bolt holes) Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted December 13, 2000 Share Posted December 13, 2000 But are the flywheel "offsets" the same? ie. is the friction surface the same distance from the crank and all that jazz? I assume the turbo has a larger diameter clutch, no? ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...
Drax240z Posted December 13, 2000 Share Posted December 13, 2000 Turbo's an 2+2's use a 240mm flywheel. (the diameter of the machined surface I believe) The NA's use a 225mm flywheel. They will interchange from car to car (all the cranks are the same) and transmission to transmission. (the T5 may be different) Yes your 77 tranny will work. I'm still looking for a 240mm flywheel myself. I think you can get by with a 225mm and a strong clutch using a mild turbo engine. (I might have to go this route for the time being) ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted December 13, 2000 Share Posted December 13, 2000 So, I don't need to worry about using a different master/slave cyclinder or fork or release bearing/collar or anything? So, ACT's web site says their 225mm clutch will only take 250 ft*lb of torque... I'll have lots more than that... How reasonable is their 250ft*lb figure? Will it do 400? Opinions? ------------------ Morgan http://z31.com/~morgan/s30 http://carfiche.com Quote Link to comment Share on other sites More sharing options...

I'll have lots more than that... How reasonable is their 250ft*lb figure? Will it do 400? Opinions? I just went through this with my Centerforce Dual Friction. After about 1k miles (that's a couple of year's worth for me, unfortunately), the DF started slipping in the higher gears. It had done fine up to that point, and had been dynoed at 400lb-ft at the wheels. I talked to a technician/sales guy at Centerforce, just to try to find out whether this was a freak occurrence, and if they could set me up with a useable clutch. When I told the guy the dyno numbers, he said that he had nothing (for the Z, anyway), and that he was surprised that it lasted as long as it did. He forwarded me to ACT, and they gave me pretty much the same story. They then forwarded me to Clutch Specialties. Anyway, I talked to the guy at Clutch Specialties for quite some time, and he seemed very knowledgeable, and was able set me up with a sprung center 225mm clutch with a slightly higher effort that would hold 450lb-ft. Also, it only cost ~$250 for the clutch, pressure plate, throwout bearing, and alignment tool. Also, he had everything he needed in stock, and sent it out exactly when he said he would, which seems to be a rarity lately (at least for me). I have not had a chance to get the new clutch installed, and since there's about a foot and a half of snow on the ground, I won't be able to evaluate it anytime soon. But, it might be worth your time to check with them and see what you think. http://www.clutchspecialties.com Quote Link to comment Share on other sites More sharing options...
