hi,
recently driven two 6sp cars mates st170 focus bit of mway and bit of ooliganisism round backroads in surrey, then a vw tdi people carrier with a 6sp gearbox drove the vw from newcastle home to london.
both vechicles fill very diff roles but now after driving them i think i would like 6 gears in my escort if poss.
however few Q's

is the 6sp st170 gearbox actually any good?

will it work properly with turbo engine ie ratios, torque, final drive longer or shorter?

the car will hopefully see some track time but mainly road use.

as always any views welcome
