right gonna build an efi cvh from parts i have spare

i have an efi xr3i

i simply wanna know if i can use the head from the xr3i engine on the bottom end of an rs turbo mfi item

are the any differences in the xr and rs heads or iare EFI heads all the same?????

i had herd somewhere that to convert to efi u can use xr2i parts e.g head and inlet

 

Its all the same.

i would urge you to use the EFI block and just drill the oil return its missing over a turbo block

 

thats to expansive will need pistons etc fuk that!!!!!!!

the erst bottom end is there and ready, was hoping u'd reply

 

Swap the pistons etc over then. Its ESSENTIAL the crank sensor is spot on, and you have to drill a 31mm hole, which aint guna be the easiest job.

 

oh shit forgot about that bit looks like i'll be buying a fiesta turbo bottom end

 

Seriously rebuild the pistons etc into the EFI block if you can.

I would much rather drill an oil return over a CPS hole any day (P.S ill be drilling my CPS hole for mine soon )

 

but the pistons may not match up proprly markeings etc or will it be ok????

will i just need the pistons from the mfi engine????

its just gonna be cheaper to get a fezza engine aint it

 

Nah the blocks are the same, same bore sizes and everything.

Is the MFI block standard bore size?

 

I thought the EFI inlet ports were different, Cut outs for the injectors

 

not the head

safechav set me straight...many thanks
