brought an efi head thinking it would be a straight fit onto my escort rs (mfi) I'm having omex fitted to it which will make it efi but that still won't let me use the efi head will it?

any help. Joe..

 

I've got a 1990 EFi head on my 1985 MFi block and had no problems at all.

Why do you think it wouldn't fit?

You can't put EFi inlet manifolds on MFi heads because they don't have the cutouts for the injectors. Was that what you were thinking of?

 

^^^^ Spot on, I also run an EFI head on a MFI block on my track car

 

but what I mean is can an mfi inlet fit on an efi head? because my omex inlet is an mfi one just modified..

 

No need to change to an EFi head if your OMEX inlet is a modded MFi one.

Or get an adapter plate to convert it

 

Apparently the stud/bolt holes are completely different though, only reason i can think of the mfi omex inlet fitting is because its got the right holes in it? Not sure what to think really, supose the best thing would be to let the head turn up and try to fit the omex inlet on it..

 

Surely if your running electronic fuel injection, you need an efi block for the crank sensor!??

 

Its all been adapted for it, some of the parts have been machined some havnt..

 

Nope, the bolt hole/stud positions are exactly the same.
I run and MFI inlet manifold, and MFI head with EFI injectors. If it was good enough for Christian and Tony on there 300+BHP CVH's it's good enough for us.

 

Haha yeah one day i hope to be running 300bhp :/

Ok well i think from what everyone has said its going to fit thankgod! Spent enough on the new head..

Thanks all for you help, Joe.

 

Im EFI head, Drilled CPS block, and EFI inlet manifold.

Im not sure what your going on about an omex mfi inlet for?

Get an EFI inlet manifold, and use the efi head you already have end your away.

Rob,

 

What you can't do is fit your modified MFi inlet to an EFi head. The port shapes are totally different.

yes it is possible i had a problem with my original head had an efi one built up used an adaptor plate so i could still run mfi manifolds as i was on mfi at the time for ease of converting to efi at a future date

 

That was what i was trying to get at my Mfi inlet wont fit onto the Efi head..Where do i find an adaptor plate jessie? or did you have yours made?

 

Jano @ oddkid used to make a mfi to efi adapter plate for your application mate IIRC

 

Oh right cheers mate ill ask him. Does the plate have a name or is it just an adaptor plate?

 

Just an adapter plate mate
