I know there's probably about loads of these threads but, Are MFI cvh blocks the same as EFI besides cps hole ? Will I be able to run my old mfi block with my fiesta turbo head and crank ect once a hole for the crank position sensor has been drilled ?

Yup CPS hole is only real difference. So yes you'll be able to fit your fez head etc to it no problem. Make sure the CPS hole is drilled very accurately otherwise the pickup will not work or the signal will be weakened due to poor alignment/gapping

The oil return from turbo is a little different too inside the sump but won't affect anything. Just drilled differently.

If s1 block then the cranks are diffrent so get the rights shells when building up.
