would it be posable to run the loyale ecu and spfi set up on a ej18 i know the sensors and plugs will be wrong or missing but would it run i might be geting a ej18 for a trade on some work i dont think it would be as good as stock but if it will work i have extra ea82 stuff ecu wiring harness whole care less the body if its possable to do it would make a great combo for the bug or if it would pass smog would it be worth doing the swap on a loyale and for that matter would the spfi work on a ej2.2 the 2.2s get better gas mileage than the ea82 dose would the throtle body give enuff fuel to run a 2.2 im sure its just easyer to use the right ecu and harness than to get and mod all the parts to run spfi on a ej engine just curiose if anyone has tryed something like this or has tryed to run the spfi setup on any other motors kinda like a standalone setup

ej swap spfi question
Posted 10 November 2013 - 11:46 AM
Have run the spi stand alone but never on ej motor this whould be crazy hard to get the right signals outa the ej motor if you could find a way to boltup a diss to ej but then plug wires coil ect I'm shure it would work good and get decent mpg. But apples to oranges better to find a ej harness to put into your car

Definately would not pass smog. And would be problematic bolting up throttlebody, installing optical disty to head, and more.....
But it's pretty easy to strip down the SPFI harness to put onto an EA82 or EA81 engine.

right you boys have smog testing non of that round here. But i think it whould pass and work very well just very hard to get working but that ej1.8 / 2.2 whould love the spi and run fairly clean but posibbly lean

Nope. Wouldn't ever pass in Ca. They do an underhood inspection. Very tough state. Plus, you have all of the problematic issues listed above. For the money you would spend alone on trying to put in a distributor, you could buy a good used Subie. Add to that the fuel and timing maps in the ECU being different..... Get the correct harness and ECU.

The dizzy can be found on a ford escort and it will bolt to the passenger's side head - there'a plate that covers the hole for the dizzy to bolt to and mate with the cam shaft.
There was actually a factory carb fed EJ that came out I think in Latin America - there are pics around of this. One of the boys in WA Australia built a weber fed EJ22 with one of these escort dizzys.
So I'd say it could be done, and the fact that the EJ18 is the same capacity as the EA82 I don't see why the SPFI couldn't work on the EJ18 with some effort.

My vw quantum is running its original 1982 CIS-L injection with the engine block from a 94 jetta, cylinder head from one side of a 91 Audi V8, Saab distributor, Mercedes injectors, and WUR from a porche. So anything is possible if your willing to put some time into tuning.

Aggreed that it can be done. I have a '78 Suburban SB 400 that I built to 300HP and transplanted BB FI onto. I had to re-write the fuel and timing maps and write a seperate PROM for passing emissions. Of course, that was years ago and now it has passed the 25 year mark. I'm no stranger to tuning or hodge podging parts together to make something unique or better. Just pointing out that for his particular situation, it's not practical nor will it pass. If it were for an offroad buggy, I'd say go for it. It would be a great learning experience.

i'm just the type of guy that likes factory wiring to stay in the car its in. if i can make it work, i will. its easier for me considering where i live, the state of NH is very laxed about emissions.
