    Difference in UN1 to UN5 gear sets?

    I'm hoping the GT40 "Brains Trust" can shed some light on any difference between the UN1 and the UN5, that would stop the use of the Albins UN5 1st and 2nd gear set in the UN1 case. Albins cant tell me. Possible problems maybe: Different centers spacing, primary to secondary shafts, difference...

    Un1 synchro improvements? For high rpm gear changes.

    If the syncro's are in good condition it would be more likely that poor syncro engagement is a symptom not the coarse of the problem. The syncro has to match the speed difference between gears in a up or down shift by increasing or decreasing the speed of the rotating mass. The rotating mass of...

    UN1 inboard brakes?

    The extra radial load place on the output splines is my main concern. I’m using Holden Commodore drive shafts which for Northern Hemisphere readers are large Lobro type CV’s that I think would take the loads and if not are a dime a dozen. My car is a mid engine 1UZ-FE Peugeot 306 3door. I’m...

    UN1 inboard brakes?
