hi mate before i got my e6 i went miles looking for a good one and beware of rust , you need to take a trolly jack and get underneath there bad for oil leaks on the transferbox as the the transferbox is a ball ache to get out!! con rods are good up to 380bhp well they say there good for just under the 400bhp mark but yr right on the edge, the standard pistons with say knorris rods are then good for 550bhp thats what knorris told my mate who had his e6 done with him and standard cranks are good for massive bhp!! my e6 with 366bhp is a proper handfull on the B roads!! be prepared to put silly money in v power!! drinks fuel even if i keep it off boost it was still a joke.. but pound for pound i still think there the best all round 4x4 for ya money, ow and cosworth now make around 80% of the 4g63t now, they make a short block, pistons, Race bearings the lot but again it will cost you big money over oem stuff!!
