spfi on 2.2 eng

greetings,a while back i saw a thread that posed what i thought was a good question that seemed misunderstood in the replies. the gist of it was that if a distributor was adapted to a 2.2 engine,could the spfi of,say,a 90 loyale be used along with the loyale computer? if so,looks like this would simplify the swap.

yea, the concept is a good idea.....but the execution would be a nightmare.

 

you couldn't just slap the EA82 disty on the EJ22. as they're very different.

 

and the crank angle sensor for the EA82 is in the disty, so you'll have to replicate that signal for the EA82 computer.

 

 

not to mention the displacement increase......could the EA82 computer/injector compensate for the extra .4l of air being pulled in?

 

 

 

if you're worried about the wiring part of the swap (which, I can understand why......not everyone gets wiring diagrams. some of my most respected subaru friends won't wire their own swaps), there are a number of people who can do it for you.

well guys,now that i have been put in my place from on high,will there be any more discussion ? i am an older guy,a hot rodder by nature,and have seen many things done after the better educated said it was unworkable. of course a proper dist would have to be found or fabricated. the question was will the spfi work with such an arrangement. beyond simplifying the swap, it could be made to look original a lot easier than what i have seen . the benefit of this at inspection is obvious. while not arguing the technical superiority of mpfi and coil pack ignitions-this seems to be an alternative. now if there is some dead nuts reason it just wont work,please just say so.

numbchux, thank you for your reply. it contained the kind of information i was looking for. as stated i am an older guy an your reply came in while i was working on my reply to the first guy and did not see yours in time.

 

glad it was helpful. don't mind GeneralDisorder......he's a little surly. and tends to get right to the point....

 

 

anyway, I'm sure it could be done. but I think the amount of custom fabrication and research that would be required would wasted since it would be a huge step down in power and mileage.

 

 

as far as making it look original. here's my engine bay. '92 legacy EJ22 in a '92 Loyale:

The only disty that get's talked about bolting into the EJ head are the early 80's ford escort disty's. These however are magnetic pickup type disributors that only control the ignition. No optical CAM angle sensor.

 

Now, I don't know, but perhaps a later disty from the same engine, but newer fuel setup MAY have a disty with an optical sensor. Also Mazda 323s of the era share many components with the escort, and could be another place to look.

 

But basically the optical disty is the big hurdle.

 

I don't know about mounting the throttle body and injector. Not sure if it would work "side draft" style. Might require a custom modified manifold, in which case all the appearance of stock disappears.

thanks again for your replies. i have had the throttle body off and apart several times-do not see any thing that would care what angle it was mounted at. so back to the disty, the mere prescence of a drive and mounting for a distributor suggests one exists somewhere. seems like our aussie friends mentioned a disty on their engines. in fact i remember seeing a picture of boat motor so equiped. anyway, all i was after was to stimulate discussion and if its either not possible or not practical i can accept that.

like we mentioned before. mounting a distributer is easy. but in order to run the car on the EA82 computer, you'll need a disty with an optical crank angle sensor that sends out an identical signal as the stock one.

 

mounting the EA82 disty to an EJ series motor would be an extreme nightmare, because the drive is completely different.

 

 

 

and, even if you could create a distributor with an EA82-compatible crank angle sensor. you've still got that issue of a computer and injector designed for a 1.8l motor running on a 2.2, which means it's quite possible that it won't ever run right.

I have a hunch the fabled SPFI EJ motors (of whatever displacement) probably still used crank and cam sensors directly on the pulleys, and not the CAS signal type. It's just a hunch. Anyone shed any light???

Thats what I was thinking just use the stock ej sensors wired to the 82 computer . when I originally made the suggestion of using spfi on a distied ej I had no I dea what went into a spfi swap and was just brainstorming. :confused:

you're probably right, but not using the EA82 computer. the signal for the sensors is calibrated completely differently.

 

 

 

you could probably do it with a standalone system. in which case, why bother? if you're wiring in a standalone (IIRC megasquirt doesn't read the EJ crank and cam sensor signals accurately, so you're looking at something quite a bit more expensive), wouldn't be too hard to use the stock EJ wasted-spark coil/ignitor. or all 4 injectors, instead of just one, that's just 3 more wires and a different calibration.

 

 

 

 

 

also, I've never heard of an SPFI EJ motor.

I heard they were in the early EJ18 Legacies in the JDM market. like 88,89???

 

IIRC A board member from New Zealand or Australia mentioned them.

 

I am not for sure on that one at all.

 

An yeah, SPFI EJ = :deadhorse:
