I've decided to convert my ERST to EFI (again ) and I've got hold of pretty much everything from a Fiesta RS turbo running OFAC management.

Can anyone give me a list to make sure I've got everything and also help me with the wiring side of it?

Thanks in advance

What loom are you using then? Space for the crank sensor? Are you doing a ZVH?

Ginge !

erm just say what ya have and we will say what ya missing

loom is seperate anyway, need all sensors and a way to fit the inlet and also the cps sensor

©hatter Box

u need ofab ur be fucked for a good map sencor then but ur be fine on ofac with one bar as thats all u need

Wazzzer

Right I will be getting...

Inlet and injectors
engine loom
coil pack + leads
charge carrier
air filter
EDIS module
MAP sensor

My ZVH block has already got the CPS in it and an EFi flywheel as Rolls ran it on FRST management

anything I've forgotten?

Oh and I think I've got the wiring from LockeRSparts now, cheers buddy

Ginge !

what inlet is it ?????, as the frst one has a different air temp sensor

what head ya got too

and i guessing ya got the ecu too , if ya got ofab make sure ya get the suppressor and also what loom is it ya got

Wazzzer

ah bugger ECU as well

its a FRST inlet, all the bits are coming off my mates FRST he's breaking

Its OFAC management, and I'm gonna try and put it into my ERST

Ginge !

cool, nothing wrong with ofac unless ya wanna run big boost and then it requires either a live mao with a skilled mapper or serious headwork/cams/turbo BUT the injectors wont flow that anyway

i fitted a ofac beige chip from msd and set it to 16psi and the engine is in another car now with all the loom ect ( i got a frst and took the ofab and converted that to ofac and also kept the engine, was bored at the time) and thats still running

speak to kenny@MSD ( Stu's boss ) as he knows awfull lot about em and can fault find off the top of his head, he talked me thrugh the conversion on the phone with no notes

take it up to them and give em a play and ya wont do wrong

besides rolls engine aint a big boost jobby and so dont think its ment for more than 15psi

Wazzzer

15psi would do me matey

As long as I got all the bits I'm happy

You got PM as well...

ze-vh phil

you will need an adapter plate for between your inlet manifold and head as the injectors will foul the erst head,

and also 2 inlet gaskets, 1 frst, 1 erst for ether side of the plate.

call fiesta frenzy for the plate.

Ginge !

unless hes got a efi head


also the addaptor plate are not needed and can be done another way, depends how biog ya bollocks are thiough

Wazzzer

Yeah sorry forgot to put that on there as well

My bollocks aren't that big lol

Ginge !

its alot easier than ya think and also quicker to find stuf ( and costs 9 quid )



just be brave and understand why and what ya grinding out, DO NOT use the efi as a template as you will cut too much away

then the fun part, make ya own inlet gasket for 5 quid

Red16

sorry to stray off topic a bit but does anyone know if the escort rs1600i flywheel is the same as the fiesta turbo one ??

Ginge !

nope as the frst has the efi parts for the cps

the rs1600i dont have a cps in the block

The best convertor plates have been proven by the means of flow testing!!!!! and comparing on the same engine/build with just the change of the plate.

SOME CONVERSION PLATES ON THE MARKET ARE VERY RESTRICTIVE AND UNEVEN!!!! BE-AWARE

Here is what to expect from a conversion plate available from any stockist




These items are machine made and DO NOT involve any Grinding, cutting, or making gaskets to hold 20psi of boost
No offence B19BAL

WHY?? Do people still use pickup's from the flywheel?? i cant figure it out?

Specialy for FRST management!!!!! instead of fitting flywheels and CPS in the block etc. Why not just use a cam sensor with 36-1 triggers easy fittment, easy to adjust + you can get more power due to the advance you may be able to give the system

Red16

Jano you got any more info handy about this cam sensor and trigger malarky? pics and prices etc im planning on using ofac management on my zetec turbo as i already have it in the garage.

cheers

Red16,
I have already done this on 16vZT and 8v MFI engines

Everything you will need is in my sig.

It will cost more than 9 quid just to clean the metal up from the floor and in your inlet ports.

To do what you have done surely you have to have the head off, valves out, or you will end up with metal in the valve seats. Not summin i would like to be doing...how did you get all the injector cutouts the same dude?

Ginge !

jano first of all the reason for using the frst flywheel and cps is 1 thing and 1 thing only,,,,,,,,,,,,, price !!!!!, you measure and cut a hole and then ya sorted

as for the head have a look at where the frst injectors actually finish in the head and then look at ya manifold gasket, tell me what ya notice, as for getting em acurate, i measured the efi head i used as a template and they wasnt acurate either , the thing i did notice was the step/wall the injector hits in the port, as for home made gaskets at 20psi, dont knock somink UNTILL you know what a the gasket is and made off, the engine i dont has had a proper leakdown test and is fine, the cars running and got no missfire and the total price of all the work i done was 50 quid, thats converting, the new cps holder, tools and gasket, hell that even included the KFC

now compare that to 100 quid for a cam trigger , this is for a 15psi conversion so the 20psi means nothing at all here

to do the conversion your way involved 100 quid for the crank trigger ( dont know if that was just the wheel on complete though) adaptor plate was 75 quid, 2 gaskets and also having to get the cps timing spot on to avoid misfires

my way involve a custom gasket, new cps sensor holder, hole saw, soft stone for the grinding and it started when i fitted a custom gasket first time and is still running

now that was no working out the timing as that was already done on the template, the ports where opened up a little , most at the edge btw then flowed inwards

and most importantly it started first time, was done in 3 days for a first attempt and doing a few hours a day and it still running

to me that means it works, if i wanted to get all techy with cam pully triggers i would not be fooking about with ofab/c ecus, would go aftermarket and get a proper ecu

cant belive when you got all that stick last year with your swearing that cossie managment is better than mfi ect and increases horse power that you are now knocking a guy with another approach whos also tried and tested it and it works

supose the difference is i dont mind what people think as it works and aslong as i do it proper i will carry on doing it

oh and how can ya get metal in the head if ya block the head and use the correct stuff to catch the tiny tiny fillings before it enters the head

as for sweeping the metal from the floor, the oil and paw prints on the floor was alot worse that a bit of metal dust

ON-UJAH

Still be interesting to know what loom you've bought? Fiesta turbo - OFAC or OFAB? Escort Mk4 EFI? Depending what you've got, there may be some wires that need cutting.

The only other issues are the breathing system, blocking some oil returns, and using the correct head bolts. You can use Duratec V6 head bolts - but you MUST use the CVH head bolt washers AS WELL AS the washers that come on the Duratec bolts - otherwise the head will not seal properly. I had a leak but luckily I found it just by turning over the engine to fill the turbo feed with oil. With 2 sets of washers it appears to have sealed - touch wood.

Ginge !

theres a thing called gasket sealent, and NO wires need cutting for ofac to ofab except to swop the map sensors or if going ofab to ofac so remove the supressor, if going xr3i to ofab/c then ya gotta chop a wire on the edis, BUT the wire that ya chop is on the edis anyway if a frst loom but its just taped back and not attached to anything

theres 3 pins to swop but dont chop the wires to do it, just swop the pins over

Wazzzer

my ZVH bottom end has had all the necessary work done to it (brass plugs in the oil ways, breather blocked, new breather put in, oil return in sump, CPS in block)

I bought it off Rolls when he crashed his XR2 and it was running sweet in there

I've got the longer head bolts as well, a bargain off ebay

The loom is coming directly out of a J reg Fiesta turbo

DUDE I AINT KNOCKING YA!!!

I totaly understand the reason you done this the way you have....... PRICE!!

But if the money was not the issue, and lets face it an extra £50 on top of the £50 you spent to do a job right is not alot.


What did you block the port with? how can you block it and work on it at the same time. What correct stuff??? did you use to catch the fillings then

Ginge !

jano thats what i spent the time working on and thinking off, its noit a secret BUT its sooo simple and stupid that im just gonna get flamed like the kfc box for a template i used

it never got any in the valves i promise though

i find alot of the time people in different industrys have a new approach at looking at things rather than follow on what they been trained hence why engineers will build a engine and not have a issue with all the worry that other machanics go on about

just like me drilling the block, i was worried remember BUT my mate whos a engineer told me to stop being a tart and as he drills things all day and repairs, mods and fixes things rather than buy new i gave it a go, was soo simple yet effective

btw the 50 quid was for all the parts to convert a mfi engine to efi including my drink as thats what i charged my mate in total

it was also done for price aswell as availabilty, rather than spend 200 quid of bits to convert then the 200 quid for the engine then the 100 quid for the fitting he could have bought a frst engine and not need mods

so it was time and money , it was a gamble but it payed off bigtime

i didnt just get a dremel out and grind then drill a random hole, i had to plan it all and as i said if ya got the bollocks then it can be done but it can go wrong too, but then so can anything


as for sealing issues that im confused with as thats why theres gasket sealent ( not aimed at you that one jano )

i was gonna get the parts off you though remember and time and money was a issue and went another way, just like the zetec engine guys do and it works
