B-Rad Posted June 19, 2013 Report Share Posted June 19, 2013 Current I'm running a supercharged 5K with 134kw at the wheels. I have just destroyed the T50 and clutch. So now I need to replace them. I don't know what punishment the T50 has been put through before me but all gear are shagged. I'm currently running a 4k flywheel with 180mm cable clutch. Can you fit a 5K flywheel inside a T50 bell housing? Will the starter motor still bolt up? Is a lighten flywheel worth the time for a daily driver? What weight have people got the flywheels down too? Options 1 T50 with new 4K HD clutch ($500) 2 T50 with new 5K HD clutch and flywheel ($550) 3 W5X with new 5K HD clutch and flywheel ($1700) W5X would be nice but its a lot of work and cash to fit a hydraulic clutch. What power can a T50 handle? What brand clutch do people recomend (Exedy or Clutch Industries)? I have always used Exedy but CI are 1/2 the price.

Taz_Rx Posted June 19, 2013 Report Share Posted June 19, 2013 Yes a 200ml flywheel will fit in the bell housing.... But the pressure plate (for say an ae71 kit) will not - i tried and failed. I've been running well over 100rwkw through my t50 for years now with no problem. Maybe just try a new clutch and t50. Otherwise look into a k-w50 setup, which is also still cable rather than k-w56/7/8 etc Quote Link to comment Share on other sites More sharing options...
B-Rad Posted June 20, 2013 Author Report Share Posted June 20, 2013 So to run 200mm clutch I need to go to a W5X box. So to upgrade to a W50 I need K-W bellhousing, 5K flywheel, 200mm clutch, tail shaft and build a crossmember. Gearbox output shaft is different so I would need to change the yoke as well. Is the tailshaft the right length or do I have to find one? The only advanagte I see of the W50 over the T50 is stregnth. So for the work I might as well fit a W58 for the gear ratios. Any recomedations of clutches? Exedy or Clutch Industries? Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted June 20, 2013 Report Share Posted June 20, 2013 W50, t50 and k50 are all the same length so you just need to change the spline on the gb end. I prefer exedy's. The draw back with the w58 etc (over w50) is cost and the fact you need to convert to hydraulic. Quote Link to comment Share on other sites More sharing options...
Clapped out Posted June 20, 2013 Report Share Posted June 20, 2013 +1 for excedy. Quote Link to comment Share on other sites More sharing options...
B-Rad Posted June 21, 2013 Author Report Share Posted June 21, 2013 So my plans are W50 gearbox behind 5K flywheel with an Exedy HD clutch (TYK-6319HD). Just need to pick up the parts this weekend. Get the flywheel machined. Put it together. Fabricate a gearbox cross member. Fit yoke to tail shaft with an old holden uni. What’s everyone thoughts on lightened flywheels? My engine builds revs really quickly so probably no need. Quote Link to comment Share on other sites More sharing options...

B-Rad Posted June 22, 2013 Author Report Share Posted June 22, 2013 I bought mhmills setup Now to get a clutch and put it all together Quote Link to comment Share on other sites More sharing options...
B-Rad Posted July 2, 2013 Author Report Share Posted July 2, 2013 Clutch is on its way (TYK-6286HD). Flywheel is getting lightened and faced. Just need to find a RA40 yoke and hope it all goes together. Quote Link to comment Share on other sites More sharing options...
B-Rad Posted July 9, 2013 Author Report Share Posted July 9, 2013 (edited) Got the flywheel back from the machine shop. Its now 2.5kg lighter and has been balanced with pressure plate. RA40 yoke is on the way should see it today. Just need to find the correct uni joint. I have been looking through the catalogs but can't find something that would work. Taz_Rx what is the part number for the uni you used? Edited July 9, 2013 by B-Rad Quote Link to comment Share on other sites More sharing options...
Taz_Rx Posted July 9, 2013 Report Share Posted July 9, 2013 Never ended up fitting mine as I ended up with a k-t instead. I took a tail shaft to a mechanic and he reckoned it could be done with some old holden uni. Quote Link to comment Share on other sites More sharing options...
