im getting mixed opinions, how easy is it to put an erst engine in a frst i have and want to run efi but i hear the heads are different. cheers

 

The heads are different mate as the EFI head has a cut out for th einjector that the MFi head doesn't have. Th eEscort block doesnt have the hole for the CPS either

 

so whats the easiest way to do it then with an erst engine and an xr2i engine sat infront of me

 

You can use th eXR2i head and cam I beleive as the only difference is the cam pulley (or so I'm led to beleive.

In theory you could use the block from the Escort (drilled to take the CPS) and the head and cam fom the XR2i. I think

 

could i use the cam pulley from the erst? will compression be ok?

 

I seem to recall th eFiesta and Escort cam pulleys are the same. There will be people on here that will be able to back up my thinking or squash it flat dependeing on whether I got it right

 

is it easy to drill hole for cps? wont i need to change the flywheel

 

yes you'll need to change the flywheel for an efi one. you may be able to use a sierra 1.8cvh crank pulley instead though, thing that has a trigger ring on it the heads are different, but you could het the ERST inlet manifold modded to take the efi injectors.

 

cant you use the efi inlet manifold on a erst head with a frst crossover pipe? been told by another forum user that the efi management is very easy to convert to run on erst engines

 

The later escort blocks had the hole for the CPS sensor, but with this method you will need to change the flywheel.

Use a machined 1.8 Sierra EFI crank pully and CPS sensor

 

Ive got the sierra crank pulley already machined and a bottom cover with new ford CPS and also a good working spare if you looking for the bits

 

how does 1.8 pulley help then?

 

Have a look at my conversion.....

Wouldn't it just be easier to get a spacer plate made up with injector cut outs to fit the EFI inlet manifold to the MFI head and then have a CPS hole tapped into the block along with the swap to a EFI flywheel (you can grab these off of any CVH EFI engine, FRST, XR2i 8v, XR3i EFI, Orion mk4/5 EFI 1.6 CVH etc.) rather than using a Sierra CPS? It's just that I thought using the Sierra CPS would require the spacing out of the alternator bracket itself? (I had to have this done by Gadget with my Cossie management conversion).

Cheers,

are the xr2i heads the same as a frst one? if so il just swap heads and fly and tap hole, how hard is it to do the cps hole? alternatively what do i need for a zvh conversion

 

The XR2i heads are the same mate (just make sure it's not been skimmed).

Cheers,

Andy

 

I have an escort engine You will need an efi fly wheel and the 1800 crank pulley set up is the easiest way and a adaptor plate that sits at the back of the head. Both can be purchased from jano http://members.lycos.co.uk/oddkidd/
