no i didnt say that but as your asking yes i am cts stage 2 bc type with cryno gear kit treatment and quaife diff works fine !! and as for the old bc type box ive had 16 rs turbos all on the road used daily the standard bc type box running at 286bhp upwards and 320 foot pound lasted 8 years or more with the standard ferguson viscous type diff so each to there own experience i say im not going to get in to a 20 page argument about gear boxes but a bit of mechanical sympathy dont go a miss , depends iff your running silly drive shaft angles , cheap comma gear oil , broken gearbox mounts etc etc the bc eventually stripps the teeth off 3 rd gear but hay ho it bolts straight on !
and due to where my turbo is mounted i couldnt run the mtx75 brackets .
and the 6 speed getrag box used in the st and the mini cooper s !
after 12 years at bmw parts i can tell you the mini cooper s box 6 speed getrag breaks fine at 167 bhp on a 1.6 mini cooper s .
over and out
