well my main concern is that i've been told that once you get over 200 bhp with the amount of torque that goes along with it, the gearbox is the weakest link and things start going pear shaped and i dont fancey swapping gearboxes every 2-3months or paying 1500 for a quaife box.
the other ting i forgot to ask was about the pistons you have used how did you come to get hold of them as they look used????
and if so how much did you give for them???
