gents and ladies. my series 1 turbo keeps lunching the second had gearboxes i am putting in it. the car is running 200bhp and and i do a lot of motorway driving where i will cruise at 90 -100mph.....

I am thinking mk5 diesel box? does this fit. Whats the deal with mtx75 boxes? are they stronger than ib5? let me know your thoughts....

cheers
