Hello there!
This morning I've dragged a ford Granada Mk2 out of a barn that has the 3.7 conversion. (2.8 cologne with ranger crank bored to 95mm,hot cam, flowed head, stainless valves etc)
the supercharged kit was fitted afterwards by a company called aw track sport. Although the owner didn't want the full conversion doing and got it back to "tinker" with the fuelling himself.
Now I won't be selling this car on, I restore old fords for a living and but haven't had a ton of experience with the 2.8 cologne.
Personaly I think the k jetronic is too crude to be able to be used efficiently and reliably with a supercharger application and don't want to kill a very rare engine.
Im trying to explore as many avenues as I can find.
Obviously I want to run aftermarket Ecu and coil pack etc
this is where I am
they made a 2.8 efi in the MK3 Granada that could be modified and run megasquirt etc but I'll be dammed if I can find one!
Leaving this question,
can I fit a 2.9 inlet manifold and plenum, injectors etc to the 2.8 heads or have I missed something and with souls daft
any other ideas for my fuelling problems? Any advice would be awesome

Emerald ecu and ideally throttle bodies. I would not touch mega squirt.

steff19

Thanks caddyshack,
fair play to your reply regarding megasquirt (me being me is thinking cheap and cheerful with better reliability than standard)
supercharger with throttle bodies? Am I being daft, is this possible?
Thanks again

Didn't pay enough attention to the charger but I would have thought one throttle body would do it with injector per cylinder. I had mega squirt on a car I bought, I gave it to a very talented mate and we both thought it was pants...I will ask if he still has it as expect he will give it away, as I did.

Do speak to Dave walker at emerald, he will tell you how to make it work

steff19

Thanks buddy
really appreciate the help!

Anything can be adapted.

If it had injection before, clearly there is room for injectors. So it would be a case of modifying your intake to take modern injectors, make up a fuel rail etc etc etc.

As for which ecu, that really depends on budget, but there are dozens of options from very cheap to not very cheap.

I believe the 2.9 manifold and plenum can be made to fit the 2.8, but requires a bit of cutting and welding around the water outlet area of the manifold. Also I believe that there a couple of bolt holes in the manifold that need modifying to bolt to the 2.8 heads, so far from a straight swap.
Your best option if you can find one is the MK 3 Granada EFI manifold, but be prepared to part with a arm or kidney to afford one.
I think the EFI 2.8 manifolds came out on some Swedish and Belgian Sierras so may be another source to look at.

The mechanical k jectronic can be modified quite well using parts from Audi/ Porsche but you will have a job finding specialists these days to tell u the exact parts needed etc. Alan jefferies who runs engine tuner used to be the one too see sure he's still trading.
Getting anything of a 2.9 efi to fit inlet wise is a nitemare as their have 6 ports where as the original had 4, not impossible but a lot of work, finding a pair of swaymar 6 port heads and manifolds would be your best bet but their rare, were still available a few years back through Rs Williams Aston Martin specialist but are ŁŁŁŁŁ!
Be worth having a chat too Dave emerald to about his ecu and he's worked on plenty of v6's over the years.

Can't thank you guys enough, so we have two main contenders, modify the inlet to accept modern injectors or find a efi 2.8 set up, thanks again!!

steff19

Well I've found an Efi system, came with VW Audi injectors and what looks like a kit to convert to coil pack!
Anyone know how to convert it to run a coil pack by any chance? Haha

stevieturbo

Well you're saying it is a kit to convert to a coil pack....so use the kit as is.

Nobody here has any idea what you've bought or what it can or cannot do.

The other issue you will face is that the 2.8 cam runs the opposite rotation to the 2.9

steff19

The you stevieturbo,
im quite aware that having not pored pictures of what I e bought that then I turn nobody quite knows...what I bought...
i should of phrased what I said differently,
when people usually convert a 2.8 to run coil packs, how do people do it so I can see if there's a better suited alternative to what's come with the efi set up.

steff19

Cheers dojj,
not a 100% sure on what you mean but that just might be me, long day at work today, nothing from the 2.9 will Ben going on this one the efi is from a later MK3 granada 2.8. No idea where the coil pack and writings come from but looking into that as we speak.
cheers!

stevieturbo

And again nobody knows what coil pack or packs you are referring to....and indeed how many people do convert ?

Trying to use crap from another engine....second hand, from who knows what is rarely going to be easy or good.

There are plenty of cheap management systems around that would be a better starting point.

And your terminology is a little off....what exactly do you mean or perceive as someone running coil packs ?

Are you just referring to the coil alone, are you referring to an entire ignition system, what coil or coil packs exactly ? Be specific as everything is very very vague at present.

Is it some sort of programmable ignition you want ? Same for fuel injection ? Or just one and not the other ?

steff19

Thanks again for your response,
in a round about way it's given me the advice I needed.
The crap second hand part so that I will retain is the efi manifold and injectors alone I think, the injectors are Audi which will be reconditioned and run off emerald management, ignition again will be run from the same.
I guess I was looking for an "easy option" but alas it's not to be.
Ive spoken to a friend and given the part number for the type of coil pack that came with the inlet (although this will be replaced with a new item) and it seems with the right touch from Emerald it can be used, I'm just looking for a reliable set up but don't have a lot of experience with the newer technology on older vehicles i.e. Aftermarket ECUs, coil pack conversion, trigger wheels, map sensors etc running on an engine built in the 80s
i can fix modern cars and classics, mix them together and it's still a learning curve so please excuse my vagueness
thanks again

A much more sensible approach.

There is little difficult in converting an older engine, made even easier if you have an intake with injectors/rails already available.
