Re: Ford BA xr6turbo t5 gear boxes
I have the same set up, and wondered the same thing. APS seems to think that the box is fine unless you really abuse the thing. The cluth is the weak link, so will need upgrading with serious power levels (over 300rwkw). Eddie Tassone managed 1500 rear wheel hp with this box at summernats (it was twiated after!), so the box can cope with a fair bit of power.
BA GT-P owner and loving it!
