Okay I'm building a mk2 fiesta I've got a cvh engine I've got the engine stripped and the engine is in good condition but can I turbo an n/a head? Is there much worked involved? would it not take the power? I have an r33 turbo it's hybrid turbo and it's just laying about so I'm thinking of putting on the fiesta 😎 As I know the rs turbo heads are hatched or something would be nice to not have to buy an rs turbo head if it's not hard to turbo the n/a head!!
