i know this has probably been convered many many times but i just wanna be shore in whats involved.bought a s2 rst and little did i know , went for mot and rotten.too much money to fix.so....i know some selling a mint white xr3i with a efi engine.car is very cheap and has very good shell.wanna convert it and put the bodykit and engine in it.bodykit, no problems....engine...wot is involved?use rs bottom end with efi head?is the wiring gunna be tricky?any help will be much apriciated.

 

Think the xr3i bottom will need bits doing to it for turbo to work i.e oil return ect

id use RST head and block and gearbox, fit efi maifold manifold with adapter plate, engine loom should plug striaght into car loom as long as is the the same (ofab ect) if its a late RST block? you got a hole ready for the cps (but u will need a fezzy flywheel for the teeth) or forget that and find a sierra 1.8 crank pulley, lower timing cover with cps on it (needs trimming) doing this u will need a sierra 1.8 alternator pulley and match up a belt. or forget that still and speak to Mr Jano Oddkid who sells trigger wheels and sensor for the cps bit

Think thats it matey

 

I'd just use the efi engine completely, just fit some RST pistons and drill open the boss for the turbo oil return.

 

well i thort the easiest way would be to get a fiesta cylinder head (efi) and fit it to the escort bottom end?this would work wouldnt it?sprry if im being a bit daft, im a abit new to the ford's, i know my renault 5 turbo's alot better.

 

fit a management system then u dont need to mess around puttin the rs turbo loom in , give me a pm and i can sort u 1 out

 

te Escort bottom end (unless its a very late one) won't have the hole and flywheel for the crank position sensor so you would have to use the Sierra bits as RSTski said

you'd be able to keep the loom but you would need the OFAC FRST ECU, MAP sensor and EDIS module and change one wire. If you wanted to use OFAB instead there will be a few more wires to change

check out www.rsbible.co.uk for any more queries

 

arent the valves and cam different in the none turbo efi head? (sodium vlaves ect?)

 

no

 

duno where i got that idea from then

 

Some ERST head have sodium filled valves, but they wont make that much difference, unless you are trying to build a super powerful machine i wouldnt bother in going out of your way to fit sodium valves.

Regards

 

so i wont need to get a fiesta turbo head?can i use the escort's xr3i efi one?

 

yes.

 

cheers mate.thats a big help....just out of interest ...how hard would it be just to put the rs turbo engine i have with mfi into the xr3i(efi model)?its not worth doing i know becuase efi is much better but just wanted to know if it would be easier?dont suppose anyone has a act sensor do they off a fiesta turbo?

 

Its not worth putting an MFi Engine into an XR3i That came with factory fit EFi to start with.

The MFi engine can be converted into EFi very easy by using a conversion plate on the head and an adjustable trigger setup on the crank pulley.

The CAR loom you have in the EFi XR3i can be used to run a FRST ECU and sensors.

SO:-

Conversion plate
Crank trigger setup
Management system, ECU, MAP sensor, ACT sensor.
EFi Inlet off any CVH engine.

Obviously the need for the rest of the running gear like T3 and zorst, rad etc..

(I have a sensor if you have problem finding one.)

 

where can i get the crank trigger set up from?...is ther any differance in the rs turbo cylinder head and the xr3i efi one?will i need to use this conversion plate if i use the xr3i head on the rs turbo bottom end?(sorry to ask so many questions just wanna make shore i im 100% shore wot im doing b4 i start taking things apart)

 

Jano will probably stock all the bits you need for the trigger setup and no you won't need the adaptor plate if you use the 3i EFi head

 

As wes said.

If you use the EFi Head you will not need the conversion plate.
