Have you try to find a EP6t (mini cooper S and 207RC for ex.) , the bottom end are very similar , maybe crankshaft , rods are stronger for 200hp+ tdci
I have a question for you Badman, do you know the best way to drive a VNT Turbo on a fiesta , it's for me , I think to put a DV6 swap on my DV4 fiesta , and I want to have a reasonable 135-140hp with a 110hp Focus engine setup
