After breaking various so called 'good boxes' and the odd diesel box lol, i'm on my 2nd cts stage 2 and to be honest the first one lasted 2 years of proper abuse with 250 odd bhp, and the 2nd one seems to holding up ok touch wood.

I wouldn't say they're anything that special but the best of a bad bunch, i find cts damn slow and not great to deal with but again not found anywhere better!

The mtx does sound good but as much as people say it's easy to do etc, it's really not as straightforward as fitting another bc lol though i know it's probably the best answer for 300+.

Tbh Karlos i'd really look into at least getting one rebuilt yourself unless you really do know where it's came from, i've been bitten too many times now to fuck about with 2nd hand stuff that's done 500 miles etc as it always seem to cause more hassle than it's worth
