I would like to collect your thoughts on replacing UN1 with more durable and modern transaxle able to handle up to 400 lb-ft.
I'd like to start discussion by presenting an idea of using 6 speed Cayman S transmission.
I'm curious if anyone has installed one like this in his/her Esprit, yet?
California Motorsports Porsche 987 987c Boxster Cayman transmission section
178.33 MPH at 7000rpm, cable shift. They're modern technology; shift lightly and more quickly than the UN-1 and you could use/adapt a Porsche Boxster shifter.Getrag rates them conservatively at 380nm which is about 280 ft-lbs of torque. For road use, not drag racing, one might get away with 400 ft-lbs.
