I have a Leone Ea82 1991 model right hand drive, im tired of the engine i would like to change the engine put a wrx engine may be a 1996 model engine i understand it’s possible to swap an EA82 to a WRX motor that’s fine. What I am a little worried about is the ECU wiring or the entire motor wiring. This is what I want, a WRX motor in a Subaru Leone I understand it fits in what I am not sure is the wiring how will that be done can I get some diagrams or pics, something to guide me though the wiring process or if possible the entire conversion process may be pics e.t.c

Thanks

Hi,
Its quite a bit of work but check out this thread of my conversion and concerns.

http://ausubaru.com/main/modules.php?na ... highlight=

and the conversion:

Also the sticky in the main conversion area:

For your info, not sure of your abilities or Subi knowlege, My Vortex, is principally a "L" series with a different body.

My suggestion is that if you do a conversion like this, if your unsure of the wiring ( and you must have the ability to source connections in your own wiring loom, so a reasonable 12V understanding is recommended) that you get the new engine loom stripped by someone who knows how to do it and has done it before.

Tim's thread, will give some background on different models, but from what I can see, each conversion tends to be a little different - especially where measurements are concerned.

A full 1/2 cut is recommended, but not essential. If you make a deal with the dismantler, that you get ALL parts required for such a conversion, ie things like clutch pedal assembly, speedo cable, throttle cable, mounts, linkages, shifter, etc etc etc. even if you have picked up everything that you THINK you will need, make sure you can go back.

Your ratio would probably be 3.7, so you will most likely need to change your entire running gear, or use an adapter plate and use your own box ( not sure who makes them, but someone here on the board can do them or put you in touch with someone who can)

Good luck, well worth it :D ( - if you are good mechanically, It doesn't take too long, but there are lots of little things - Clutch, radiator mounts, turbo crossmember alteration - which sounds like will apply, IC location and if yours is currently a non turbo, different drive shafts if you use the full drive train)

Even though I have done this, I do not by any means consider myself to be ANY sort of authority on the subject. THIS forum holds the wealth of information and I give my success to everyone that helped, supported and encouraged me.

Wow, Nairobi !

Do your road and transport authorities allow modifications or even care that you might be tripling the power of your beast ?

You MUST get a front cut. It's simply not worth all the ass-ache of missing bits to forgo this.

Wow, Nairobi !

Nop they dont care here in Nairobi we have crazy rides hooked up even better companies that hook up rides like crazy so i really doubt the authorities care.

I read through many post but there's hardly anything about the ecu wiring that is my major prob coz lets say i want to put a legacy turbo motor the ecu comes in again if i go for the wrx motor the ecu again comes in, if the ecu connections are not right i dont think the motor will run for now i need some to help me out with the wiring process ill get the wrx motor with the ecu but wat cables will connect to the ecu for it to run.

amk, you need to re-read the post link about stripping the wiring loom. This is where a front-cut or 1/2 cut applies. You need the wiring loom and ECU from the donor engine.

It basically involves removing all the wiring that goes to the ECU to the engine, and removing all the rest as this is no longer required. Then splicing this into your vehicle by running it as a separate loom or merging with your original one.

An accurate set of wiring diagrams for both model vehicles help. This will give you info where to connect power feeds, grounding etc. and sourcing the devices connected.

This task it not easy unless you are confident or familiar with engine wiring.
You may need to seek an auto electrician to help here. Get some quotes first.

Not being a wiring person at all I still decided to tackle my wiring head on myself (eventually!). I figured it couldn't be any harder than fitting the motor - and in the end I found it quite easy.

3 days (an hour or two a day) later I had a beautifully stripped and presented loom.

As said above, get your hands on a good set of diagrams. And don't cut anything you don't need to, triple check every wire just to be sure.

Im not a wiring guy my self, im an engine guy i hv done some wiring but never delt with ecu's i have fixed up about 3 leone ea82 engines this time i decided to change the motor the ecu wiring is the problem will the motor run without the ecu connected?. The other prob is that my leone is non turbo so i dont think its going to be easy, any thougts!!!

Being non turbo it will require modification of the engine crossmember to clear the up-pipe for the turbo.

The engine will not run without the ECU. The ECU controls ignition and fuel delivery on these motors. If you're not confident in wiring it yourself perhaps you should find an auto-electrician who is. Get as many wiring diagrams to suit your engine as you can, hopefully this will make his job a little easier.

Most of the information is about Legacy's.

Thanks

Ill gather up some files during the next day and email them to you. I have the ecu pinouts, but I need to ask the guys HERE on the forum about your adaptor plate, as I didn't use one.

Guys,-
Amk needs info on a adaptor plate, from a EJ20G, to a std ea82 box. I dont know what type, maybe Amk can tell us. He has PM'd me re some files I have and does know that it isnt the best thing to use the adaptor plate, but is good for starters - and some forum members use them with success. I am not familiar with the different boxes, as I have only taken notice of my own stuff, so I don't know what config his Leone is.

All I know is it's a
Leone Ea82 1991


Amk:

Is it 2WD, 4WD, single range, duel range or do you know what size clutch? 8" or 9"

- are these the correct questions guys?

I'm emailing some wiring details asap for you,
Cheers
Chris

It’s a 4wd selectable, I got 4wd high and 4wd low its not the button type

I mean the hydraulic type it’s a lever and the clutch plate size is 9” (inch). (Manual trans)

Well what I can tell you is that the engine wiring is very simple jus a few

wires like

1 wire to power the carburetor
1 for temp gauge
1 for exhaust temp light
1 for the cooling fan
Coil
Distributor
Starter
The rest are for the a/c n alternator. For now that’s all I can remember

Basically the wiring is very very simple let me put it this way when I build these type of motors (ea82..) I don’t fit the motor in the car (gearbox) I start it out side test the timing check for leaks etc I don’t need to fit it into the car to start it but from what I understand the ej cant run without the ecu’s connected.

Any other questions please be free to mail me

Thank you all for your time n help.
