still in need of help i have a 1990 efi xr3i cabriolet (elec roof), i'm going for an rs turbo conversion,

So far i have bought an engine, gearbox, exhaust, turbo, pace intercooler, oil separator tank, cross over pipe, baileys dump valve, bigger brake conversion, i have 2 metering units, 3 MFi inlets plus wiring loom and ecu's from Mfi (all came from the same bloke i got the engine from he said it came from a cabriolet, but im guessing it was older than 90 an therefor would have been MFi)

i have spoke to a few people and they have said go with the EFi like the fiesta, but im worried that my current EFi manifold on the xr3i wont be right??!! also if i do go EFi do i need OFAB or OFAC? as i dont really understand what is the difference between them?

but if i go MFi will have have to chop about with the loom as the roof is elec etc, and ive been told i will need a different fuel tank, fuel pump and fuel pipes....is there anything else i would need???

i dont want to give up on this but i am in a bit over my head and would really like someone to help simplify things for me and to get some clear advice!!!!

so all help will be massively appreciated!!

thanks in advance!!!


Also still in need of hoses, radiator and header tank, boost hoses etc if any1 has them for sale

Just go efi with diffrent managmnt. aka cossie/gotech/omex/megasqurt

i think it goes like this:

Ofab - for over 2bar boost
Ofac - for below

Note that these systems are mapped by few people which might then mean you have efi but no one able to map it.


your car loom should be seperate to your engine loom. Speak to karlos he has a escort cab running rather sweet

dannymc86rscab

sweet, jr's next to scrap-co, down a little private road??? kane capel's uncles place aint it?? cool nice one for that tho mate ill try to get down to ya on the weekend?? out of interest how much for the rad and header tank?

..hello mate is it easy enough to get done then?? i.e plug and play or sent off to be done?? im watching Sierra 2wd 3dr RS Cosworth engine wiring loom L6 ECU
and Ford Fiesta RS Turbo, EFI, Bosch 701, beige injectors will they work together or will things need to be chopped and changed about?

cheers mate

Matt carter

Thats the one mate. U no the capel's well?

mentalasanything

Right, it's all in the sticky at the top of the room. As your car is EFi you have 90% of the stuff.

Get hold of the following:

• Fiesta RS Turbo block and head.
• Escort RS Turbo T3 turbo.
• Fiesta RS Turbo OFAC ECU & MAP sensor.
• Fiesta RS Turbo injector/inlet wiring.
• Fiesta RS Turbo air charge temp sensor.
• Escort RS Turbo exhaust

Plumb it all in using your gearbox, inlet and loom.

If your wanting to go cossie managment got on www.oddkiddcreations.co.uk

You can set up cossie managment at home with some basic skills then drive to janos for a live map. depends what your budget is ? ??

wicked cheers mate, well ive got a escort rs lump what is the difference between the heads on them or the xr3i?? ive got the exhaust and T3 turbo and rs turbo box (limited slip diff), so that would leave just the

ull need an efi mfi adapter plate if ur gonna use an efi inlet on an escort rs turbo engine

conor.rst

iTrader: (3)

Yeah hes right. you can get one from jano. www.oddkiddcreations.com

mentalasanything

As said if you want to use the head on the ERST lump you'll need an adaptor plate. Also, if you want to use the ERST bottom end you'll need some form of crank pickup.

Here's what I would do:

• Sell the ERST engine
• Buy a FRST block and flywheel (Crank pickup is in the block and on the back of the flywheel)
• Use your XR3i EFi head and inlet (They're the same as a FRST and XR2i)
• Fit an RS Turbo cam
• Add the parts you have listed above
• Enjoy

My honest opinion is not to fit FRST management to anything other than a Fiesta RS Turbo running the T2 Turbo the management system was designed with.

There are countless reasons why.
The top ones are that the cost to have anything adjusted to suit your engine will cost hundrerds from the likes of stu@msd or Ahmed etc. It will take time for them to do this which means you will need to leave the car there once you get it there and then have to go back to pick it up with loads of expences.

Below i copied off my site which has a very good thread called benifits of cosworth management. For anyone interested in any management systems this will make a great read for you. It explains alot about not just management systems but how the industry works aswell.

http://oddkiddcreations.co.uk/viewtopic.php?f=2&t=10414


1.FRST uses batch firing which is very crude as the engine management has no idea where the camshaft is in respect to the piston, so sort of guess's and takes averages. Later Zetec engines had this cam sensor as the next evoloution for the management. At high power, high boost, high speed, this is far from ideal without a cam sensor. This is why every other well known companys boasting other management systems will use my sequential cam sensor setup. Pretty much most of them that you would know of bought direct from OKC. So if you look at low costing management systems they will not be sequential. You will need to buy one of their top ECU's to get that which will never be made clear at the time of purchase.

2. FRST uses 2 bar map sensor which means you can only run 1bar of boost which is pointless, can run more with MFi. Yes we know you can fit 2.5b map sensor or even a 3bar. Who will map this in and at what cost? How long will thet need it for? How much for the extra bigger injectors, etc etc... Well from my experiance and the people who have had this done tells me that maps is around 500quid, plus the other costs and you will need to travel and leave the car with the tuner get home and then back again to pick it up..

3. Parts and sensors for this system cant be bought new. So if your sensor one day does fail for whatever reason you have no real way of getting new ones only second hand crap off website full of scammers trying to sell you a xr2i map sensor as a FRST one same as the Air sensor which is a pig to find.

4. If you fit the FRST system to your motor how do you know that it is actually working as it should be? No computer to connect or hardware and software options. Even if you did have the equipment you still might not get it connected without it using the full FRST loom. SO WHATS THE POINT?

Hope this helps a little. Just ask if you have any Q's.

I don't disagree with Jano, if you are in search of the best setup and in search of big power then Cosworth/aftermarket Management is a good bet. I've never been after that so FRST management is fine for me.

But if you just want a simple setup and want conservative power, say around the usual 180bhp (chip, exhaust, filter and a bit of boost) then there is nothing wrong with FRST management. Also Colins Performance can do a plug in Powerchips module for Ł115 to run beiges and unlimited boost. Might not be "the best you can get" or "Most power", but certainly a tried and tested method.

It's all about what you are after power wise and what you are willing to spend at the end of the day. A cheap simple upgrade or something for the best performance and future expansion.

Lee

Edit.

Ok, I changed my mind. I disagree with Jano's copy and paste a little.

Point 1 = Agreed. But on a budget this is perfectly acceptable.

Point 2 = Disagree a little. You can get "generic" plug in modules from the likes of collins and Superchips that will give you the use of the 3 bar map sensor. Not as good as alive map, but good enough on a budget.

Point 3 = Disagree. All sensors are still available from Ford.

Point 4 = Disagree. If the system is in LOS then you will know. Plus a power run/CO2 setup on a rolling road will let you know of most issues. Granted there is no on board diagnostics but then this doesn't claim to be a top end system.

Yes for sure on budget its ok but if you have a decent MFi setup running 200bhp whats the point in all the hassle for less power. With no assurance what you fit will work and be right and at what cost, not much less in the long run to weber. Escially if you want to get it matched to your engine with a map. Dont forget its ment for a T2. Weber which will get more power, never lose value and easy to go back to std and sell on the stuff or fit to another car. Before you say you can do the same with ofac/fab you can but not as easy.

Superchip will not offer an off the shelf chip to run a 3bar you will need a tuner to do this map for you. As far as i know i dont think collins will either. Saying that i cant remember the last time i bought a new chip from these companys so they could offer this now days. I trade with both companys for other items so could ask no problems.

Anyway how many of these have you seen working how they should, trust me that alot of cars i see with the cheapo chips dont run how they are ment to and produce the power they claim. In my experince the best chip you can get is a superchip even tho they aint all that either unless you get to make the adjustments yourself or via a tuner.


I dont think so mate, try ordering an ACT (ofac or ofab) and a FRST Map sensor for OFAC. Also if you can find them how much are they from Ford. I can buy every cosworth sensor from anywhere in the country which is also the same sensors used for pectel autronic or any of the top ECU's. The price for new sensors are less than they are for some of the FRST sensors secondhand.


The normal everyday person wont mate, they come to me all the time running like a sack of sh1t. Takes lots of guessing and experinace to understand whats right or wrong. Unlike a cosworth which can be pluged into the laptop and diagnoised in a matter of minutes. Which in the long run costs the customer less as you havent wasted loads of time switching sensors and tested crap ford senors.

So going by what you said, you need to take it to a rolling road and pay someone to tell you that your engine is in LOS and then not know how to fix it because you dont actually know what has caused it. You can put many different diagnostics machinces in line of the FRST ecu to find out but again at what cost and hassle and where etc.


I dont disagree that its good when working and if you could get Ahmed to map it for you at mates rates then great you might see a little over 200bhp. But if you dont have a FRST or XR2i wanna be then i wouldnt fit ofac or ofab to anything else.

My 2 Pence on the subject...
OFAB/OFAC is a pointless conversion as you gain nothing over MFI, it isnt even more reliable than MFI any more as everything is 20 years old and just as prone to failure.
If your going EFI then there a many aftermarket management choices available to suit your budget

Matt carter

Yep no kane well. And all the capels cum to think of it.

Yep Jano no's his stuff. Just look or read about the cars.
I saw his xr3 at brands hatch. Fast car.

But the man i go to is paul at http://racepowermotorsport.com/

mentalasanything

Let's not forget the point of this thread guys. The OP already has an XR3i EFi he wants to convert to RST and doesn't want to mess around with the loom.

I get all your points Jano and do respect your opinion, I'm not saying what you wrote is wrong, just that it's not the only option.

I agree btw, going MFi to OFAB/OFAC has no point, but were not talking about that here.

Yeah thats true, if it's want he wants help with then fair play of course!

dannymc86rscab

hello fellas just an update i went up to see lenny (H20LRW) this evening and he said as i have everything ready for MFi to use that option as i wont need to do to much tinkering, a case of changing over the looms and then sorting out the rear of the cars wiring, which i'm sure wont be too much trouble, and a few other little bits, also i should be ok to use current tank and pump, and then just modify current fuel lines to work with the metering unit etc, im not goin for massive power atm just want to have near standard and (exhaust, filter and chip). after a while i will be planning to go bigger but maybe later next year!!! maybe different car too!! but for now want to just get used to the erst and its workings!! thanks for every1s help and suggestions!! much appreciated!!

mentalasanything

It is quite a lot of tinkering to go from EFi to MFi especially when you need to modify the wiring and the EFi pump is too low pressure.

If it's what you have and what you want then go for it! I personally would keep the EFi, a lot less hassle for you than retro fitting MFi to what you already have, but that's just me.

Good luck and keep us up to date!
