Good evening I'm looking to converting my mk7 fiesta zetec s tdci to a zetec turbo and was looking for advice on which engine to use as I've got a st170 engine and a 2litre zetec blacktop I've got mk1 focus rs pistons and going to order forged rods and I've also got the decompression plate as well which I'm going to have fitted when I have the engine rebuild . I look forward to your feedback many thanks

 

My feedback would be, sell the tdci, and buy a fiesta ST and tune that a bit, will be cheeper and easier in everyway, and retain more value.

If its big power your after, save a bit more and buy a focus RS and tune that. Thats assuming you want to stick to a fast Ford
