im shortly about to carry this conversion out, im going to use my erst head with a adaptor plate for the frst mainifold.

does any 1 know if i need any other adapter plates other than the inlet plate?

has anyone carried out this efi conversion?

also when the conversion has been carried out, what mods will i need for around 180bhp. a stage 1 turbo will be going on aswell

 

nope you'll just need the inlet plate for the injectors

did this conversion myself and VERY happy with it

 

just got mine running easy conversion to do when u get the right information mine is on a ofac ecu and will be running beige injectors and a 195 chip any questions just give me a shout

 

which way did you do it wes? frst flywheel or 1.8cvh cps sensor and crank pulley? do i need a frst throttle pedal and cable?

 

is that all your mods? chip and injectors? for 195bhp?

 

xr3i cable and pedal i used and the sierra cps havent thought the mods through properly yet thats just my rough idea i have

 

forgot my car has piper285t2 cam 1800 bottom end stg2 turbo grs intercooler -34 actuator etc

 

im going that route too

is xr3i cable n pedal different to rs turbo then?

where did you get ur adaptor plate? was it supplied with gaskets?

what spec are you running ian?

 

adapter plates are cheap from area-six think gaskets r extra
pedal needs to b changed cos the cable has different ends

 

oh i see

what about rocker cover and charge pipe? need diff ones or they ok?

 

What do you do with regards to wiring up ecu relay and fuel pump relay as im going to be doing this to my mk3. Also I take it the rev counter will then be wrong due to the dis unit?

 

Q: Do I need an EFi dash pod for my car?
A: No, you can run a wire from pin 11 on the E-DIS unit, to the back of your dash pod, to the tachometer input. This will give you a clean RPM signal.

how can i get the chatter (compressor stall) when everything is up and running?

 

by makin sure there is no crappy dump valv on it and just air filter off the turbo...

u can get 180bhp easily matey...

bout 14psi... -31... chipped ecu... bout do ya then!

 

Wkd, so no need for beige injecters? you running efi steve?

 

yea u need bieges too matey

yea im runnin cossie management matey!

 

cool, cossie management much agro to fit? which inlet did you use for that?

 

i didnt fit it myself but have took it out and put it bk in...

theres loads of different ways it can b done... but there is alot of custom stuff needed so it isnt easy...

not cheap as fezzy managemnt swap neither...

i use a modded fezzy inlet manifold.

 

Mate, as I did this conversion myself I'll help you through it as you go. I learned alot when I did mine, and I have some wiring diagrams that'll probably help you out

 

Oh, and have a look here

thanks

 

im doing the 1.8cvh pulley way, do i need to change the alternater pulley aswell? and run the 1.8cvh alternater belt?

 

u need the alternator bracket and adjuster arm off the sierra cvh my alternator i just changed the alternator pully an it aligned spot on its safer to get the sierra alternator though that way it will deffo fit

 

ok cool

you used a EFAB ecu and loom didnt you ian r?

 

i am using xr3i efi loom ofac ecu and map sensor

 

going to be doing mine with EFAC loom ecu and frst mainifold

am i right in thinking that i wont need to do as much chopping and changing as you did ian with ur xr3i loom?

 

xr3i efi is a straight fit no chopping for me just extended a few wires and the ecu is inside the car now

you mean ofac not efac

 

oh yeh ment OFAC

 

will a 1.8cvh alternater bolt straight on, is the adjuster arm to tension the alternator belt?

 

the sierra alternator will fit straight on with the above brackets the adjuster arm is to tension belt

 

I used a fiesta turbo block so it had the EFi flywheel and CPS already there

if you keep the escort turbo charge pipe you will need to get a bit of Samco that will reduce the sizes down (the fiesta turbo throttle body is bigger)

any more questions just give me a shout

 

im sure there be plenty more questions when i get going cheers

 

thanks, if i choose just to use the 1.8cvh alternator pulley on my 1.6 alternator, will it be a straight swap and then the pulleys will line up? or will it need spacing out ect

or if i use the whole 1.8cvh alternator can i tension the belt the same way as before ? or will i need to fit and use the adjuster arm?

 

could someone tell me the differance between ofac an ofab ?? also are there any wiring diagrams i.e which wire connects to where as i am about to do theis conversion aslo

 

OFAC uses digital map sensors (2 bar).. OFAB uses analogue (eg, cossie type, 3 bar etc.).. OFAB makes life easier tuning..

 

You wrote nothing else is needed.

Doesn't it matter that in the EFI head inlet ports, there are places drilled in for the injectors, and in the KE-Jet head there are none?

Is it noticeable, that the injectors are not so close to the valves, and do not inject diretly to them?

 

Heres the plate im getting



the adapter plate isnt just made for the mainifold to fit the head, in the yellow circles your see machined grooves for the fuel to go through and is aimed into the cylinder and no all over the plate

is that what you was worried about?

 

Yes, this is what i was asking. You say, with this plate, you get the same angle for the injectors, as if this grooves were in the head. Fine.

Could you please tell some additional information about it? I think it's made from plans, measurements, not from somebodys own idea about the sizes, angles, etc.

Thanks!

 

oh i see

i spoke to mike at http://www.ferriday.co.uk/ and he siad hes made loads of these plates (so i asume there tried and tested otherwise there would be afew complaints i think) he hand finishes them aswell around the injector ports

 

Thanks, I'll try!
