Hi read through the sticky for converting from mfi to fiesta or s2 efi but i want to go to an aftermarket system so can i just fit an s2/fiesta manifold and blank the dissy off then fit a map sensor into the new manifold and a cranksensor and trigger wheel for the managment system.
Seems like a load of extra ball ache changing the head and my friendly escort mans thinks the head is the same apart from dissy.

So basically all i want is an easy method for fitting electronic injectors the managements loom will be custom made so won't need much else.
Am i wrong what are my options if i am wrong? thanks James

best to use an EFI head as the head has cut outs for the efi injectors, when using the mfi head you have to fit an adaptor plate.

You can keep the head, fiesta efi inlet is the easier option, but you will need a adapter.

are the adapter plates easily available or is it best to just make one myself any pics available of an adapter plate?
thanks for the info people

studabear

Thats a ferriday engineering plate, very nice

ALL ERST had MFI. Even all S2. Only the FRST came with EFI.

You've got two options:

1. Modify your head to use electronic injectors. I did this with my engine, I drilled out the standard sandwich plate for the MFI injectors.
2. Change head and inlet to EFI. If you're using an aftermarket injection you'll also be fine with a non-turbo head and inlet.

Theres only one head difference carb/MFI <-> EFI:

EFI had cut outs for the injectors.
iirc there's not enough material to mod MFI heads this way.


When running FRST management I'd go for a EFI bottom end with CPS hole. With an aftermarket injection you could also use the external Weber OT setup sold by Burton.

Thanks for the replys guys this info is great just started researching a zvh conversion so i get a load more reading done before i do anything else

thanks again

I'd go for full Zetec turbo conversion instead of ZVH!

luke19790_3

sure they did escort turbo with efi

XR2

says who?

Nope, not even in the 90 spec.

luke19790_3

brain might be mixed up with the xr3's

XR2

90 spec Escort MK4 were the first cars with EFI. But they were N/A.

Some sources say S2 or some S2 were fitted with EFI. But this is totally wrong.

But: 90 spec S2 usually came with a CPS hole in the bottom end

cheers guys gonna look into zetec turbo build now

columbus autos

So if i had a 2 litre mondeo mk2 zetec engine some roughly 8.5:! forged pistons, shot peened rods focus mls headgasket it'd be a start
Not sure on the inlet manifold or exhaust seen cast exhaust manifolds for £250.
Anyone got recommendations for cam timing whether to change cams?
I wanna aim for a reliable 250hp with scope for more if possible are there any manifolds available for a zetec that have a t25 flange as i a few brand new t28 variant turbos on the shelf from my 200sx.
cheers

A zetec will do 250 reliably with a t3 very easily. I would personally be looking at using the efi flywheel as the cps bolts through the block and gets its signal from the back of the flywheel. From my own personal experience megasquirt is very hard to beat but you could always go down the cossy management route, I would have a word with who ever will be setting this car up regarding management choice.

Good luck,

PS efi totally transforms these cars for the better.

Rob,

Buy a cossie.

XR2

It's very easyto beat

But all other options are very expensive...

Rob_DOHC

iTrader: (4)

Sorry i should have said, for the price its impossible to beat. However you can take management systems that are triple the price that STILL don't beat MS on a technical level, for both accuracy and performance.

What management system would you recommend to the OP then? and what ECU could you recommend that bests MS2 thats under £1000, I can do every thing i would ever need to do with MS2 on my rs turbo, sequential spark/fuel proper accel enrichment etc. The end result is a car which drives very smoothly, with stable afr's, superb start-up and a great feature list.

Im not sure what more you would want?

VEMS also with good price.

im getting a ms ecu from here http://www.boostmonkeys.co.uk/products.html
send them an email and they will help you out,
it mite be worth you asking rob dohc, above a pm as he knows all about it

bomsch

For that boostmonkeys extra £ (Ms in p&p ecu box) you get proper wiring harness and good GM sensors IMO

Rob_DOHC

iTrader: (4)

Without sounding bias either way, if your willing to build your megasquirt yourself then yes you could buy GM sensors and make a wiring harness, however the stock ford wiring loom is far superior to any DIY loom i have seen (so is 'proper') with regards to sensor noise. One of the problems with megasquirt comes from poor construction, with a bad loom. CPS triggering can also be an issue if not sorted out properly.

I also have absolutely no problems with the stock ford sensors compared with GM sensors, and with out getting technical the link above shows an ecu that is far from 'just an ms in another case'.

Remember a megasquirt 1 in kit form will cost £200, plus £90 for the MS2 board, totalling £290, untested with no guarantee PLUS you need to build a loom on top of this, bank on wire, connectors and conduit coming to £100. This is without ANY optional outputs etc, so I don't think the price is bad at all for a totally PnP fully tested bit of kit.

VEMS is also very good, its essentially another megasquirt, however the support isn't so good. Fords own ecu takes a lot of beating both in EEC-IV and L8 format, but it isn't easily tunable for an individual.

Well off topic, but good luck to the OP which ever route you choose, there is superb support for which ever you choose on this forum

I dont see advantages with Fords old wiring loom and sensors.Wiring harness must be modified anyway to fit Megasquirt and GM sensors are MS soft default ones, no need to search half a day for Ford/or what so ever sensors specifications, to make changes. If you are converting MFI you need to buy (find) EFI harness and sensors, so if you want best result pay some extra and get brand new stuff and easy fitment. I personally have done that conversion in both ways and never go back to mess with old crapy parts to fit. Just to win, i dont know, maybe ~50£? Thats my opinion, not saying everybody must do so. Peace

IMO, If you are gonna go thru the effort of coverting the management of your car for more tunability etc, then why go for a system (cossie management) which is just as old as the MFi, changing your mfi loom n sensors for other dated looms and sensors that cost the earth, when you can source newer looms and sensors 2nd hand cheap of here and ebay and get a plug an play management system thats bang up to date and much more versatile than cossie management?
Go for the OFAM from boost monkeys!

Rob_DOHC

iTrader: (4)

The point is that the OFAM is a plug and play ecu so it isn't relevant to the mfi conversion, fords wiring loom is far better than most diy looms, proper earths, properly spec'd cable etc etc, the stock ford sensor settings can be found on this forum in 2 mins, the documentation with the ecu also provides them as the ecu is car specific, but thats only relevant when converting from OFAB/OFAC, your point was that the OFAM was more expensive than a normal megasquirt and custom loom.... and its not.

However you are correct, when converting from mfi (unless you have previously converted to OFAB/OFAC like alot of people have) a custom loom should be made.

Rob_DOHC

iTrader: (4)

Thats kind of you to say dude, but i can see his point, ie if going straight from mfi to aftermarket management... thats what the gen8 will be for

We should meet up for a beer or something soon mate!

Why build a zvh or zetec turbo when you can buy a mk1 frs engine for £1000

Then manifold and turbo with down pipe can be had for £300 and it will flow to around 290bhp

And mk1 frs inlet can be had for £150

Bargain??? Then megasquirt ect job done

And nick at gatwick motors has one that needs a rebuild for £300 also a bargain

Woh i missed a lot on this whilst on holiday
My plan was to use the kit from lloyd developments a canems 4 cylinder ecu and custom made loom if i don't feel up to the job the boys at lloyd specialise in loom making and from experience i can say they look very good.
The lads at lloyd can custom design me a new inlet manifold aswell to suit the engine bay of the ME4
So i think i'm gonna see if i can get a runnng 2 litre mondeo to steal the engine from and work from there for now.
I like the look of the canems and i have vems on my 200sx and as has been said the support with vems is sparse. Lloyd dev are 25 mins from me and know the ins and outs of these ecus very well which is my reason for this choice.
They have already informed me i can use the original zetec flywheel and crank triggering and they use ford coils for ignition.
Cheers for all the info people
