say if i wanted to take a 850 t5 to the next level say to around a genuine 400hp what would need doing, i understand the rods are the weak point in 850's so is there another bottom end with stronger internals that you can fit the head on or is it a case of you have to strip and rebuild with stronger rods? also if you have the bottom end strong enough what turbo would you go for and would standard injectors be enough, obviously i know it would need some sort of custom mapping, anyone in the south west you can recommend?
lastly would the standard 5 speed gear box fit and it there a lsd you could recommend? does the t5r or 850r come with a lsd gearbox or is it aftermarket only?
thanks very much
