Hi i just bought a Fiesta mk3 and want to do an rs turbo convertion. I still havent totally decided on which engine to go for, but i think i might go for the rs turbo engine and tune it to achive some more power. Im quite new to this, have always planned a couple projects but never actually got round to starting let alone finishing a project, some tips would be nice. The Fiesta RST's are 8v, would a 16v zetec head fit onto the fiesta bottom (if so which) also considering just going for a whole zetec turbo convertion. Can i get some advice please. Also if anyone has any engines for sale, either rst or zetec turbo would be nice to know some prices. Thanks.
