Gents, welcome your thoughts.
Trying to help with disposal of 300 bhp engine (214 lb ft), and boxes go go with it.
The great Quaife box went with the chassis and potential purchaser is considering sequential, but also looking at other options.
From discussions, I recall Caterham 6 speeds if built properly, should be ok
Will strengthened type 9 be strong enough
Welcome thoughts from the powerful XE's/K's/BD's/Duratec chaps as to what works without breaking
