Please correct me if I am wrong... I think I could be but the fiesta ZS tdci is a 1.6 diesel turbo so logically speaking the cylinders are the same size as the petrol so I am thinking if I took all the turbo parts of the diesel they would bolt on to the petrol without hassle... Or am i being a complete mong

Please let me know your views

Diesel internals (crank, rods, etc) are much stronger than the petrol ones to cope with the higher compression needed for them to run (1.6 petrol is 11:1, 1.6 diesel is 18:1) you'd need to upgrade the petrol bits or it'd most likely eat the bearings or worst case snap the crank or strip the head bolt threads, either way it'd be messy & pretty expensive ;0)

Yeah I know the petrol can't take the power, but I am right in thinking it will just fit into place an with some money being spent on stronger robust internals. The car will be a monster
:p

Wouldn't you be better off getting some sort of aftermarket turbo, the diesel one wouldn't bring too much difference I'd have thought being a standard ford one.

and then there's the remap to make it all work. Just buy the ST next year.
