Re: New Transaxle Comparison / Discussion Thread Good tread,a lot of info.Keep on. I`m very interested in a box that can take high torque. Building a Lexus 1uzfe V8 engine to my Lotus and the torque capasity of the gearbox will be the limitation. What is price for the box you are...

I have did a lot of reading about the 4 speed 930 box on this forum. And it looks to be very strong. Do any know the shaft dimension on the 930 box? And how much torque it can take? The 5 speed UN1 upgrade from: http://www.gtoengineering.co.uk/gtor/page1.htm (think this is what you...

Thanks a lot it was a lot of info in this forum about the 930 box.

Hello I did think to use the ford spline.Because its very limited with Lotus/Renault High torque clutches.I have a pressure plate witch is 35% stiffer than stock. But only with stock friction plate. Where do I get a Ford sinter clutch friction plate, hopfully 235mm diameter...? So I can...

This is not real dragracing....Its on normal road surface and of couse I use the head when I do this....Most of the driving is on the track anyway.
