my zetec turbo cost me about 6k all in, with the ecu + mapping , fuel system, gearbox with lsd, plus labour ect ect ect.
the engine it's self is no bother just pistons, rods and bearings oh vavle springs, it's everything else that adds up, injectors, fuel pump, swirl pot, intercooler + piping,
just loads of stuff, you thinkyour there then you need to buy something else then something else. lol
spent over about year it's no bother.
