[Fot] [Fwd: Re: TR6 gearbox]

[greg]

    I agree. We never considered a 5 speed for the 6. We ran a Mag case 
Jerico with Kas's old close ratio splits. Some tracke we only used 3 of 
the 4 gears.
    BTW the Mag case Jerico is only about 5 pounds more than the TR6 
box. The trouble is the shift linkage intrudes on the left side and 
reduces leg room drastically. Rod wore a big kneepad on his right leg to 
keep the bruises down. If I did this again I would look at rotating the 
box 90 degrees and using the MVE shifter. I would also use the thin 
qualifying gearsets to reduce the weight and rotating mass. Jericos are 
all over Ebay now.

The original move received much badness (me included as I was running F at the time) and the decision was made to remove the 5 speed allowance for the MGB.
