respect.

progress?

where is the turbo for the EJ25?

shuffbag · Post by **shuffbag** » Mon Jun 20, 2011 5:31 pm

haha turbo would be great, but i got this engine for a song

im about to head out with a test light and find were power isnt getting in my loom, im getting no power to my ignighter/coil pack? im thinking the ecu isnt grounded and because of that its not sending power to them? or maybe a wire needs grounding since it was a auto?

power is getting to the ecu, but not sure if its going were needed.

once i get this wiring sorted it will happen very quickly

is it in?
make sure the engine is very well earthed. if not, it can earth through the ECU and fry it.

if this doesnt work i gues the wiring from another ej25 bodied car and ecu could be used? one that does have pinouts avaliable?

shuffbag · Post by **shuffbag** » Mon Jul 11, 2011 12:03 pm

so i now have ej22 wiring and ecu from a 90's liberty to run this damn thing.

im going to start chopping tonight, but if people are interested...
this is a 98's ej25 with 90's ej22 wiring
the engine loom on the intake of the 25 is differant to the 22. cam and crank sensors are on this part of the loom with the 25, but on the 22 they are on the main loom (connecting near the gearbox). so i have used the 22 items with wiring.
the throttle body of the 25 only has a 3 wire connection, but the 22 is a 4 wire plug so the throttle body needed to be changed.
other than that everything else plugs up,well the knock sensor plug needs changing but its a single wire so shouldnt be a problem

one question to the converters out there... because its a ecu from a auto car is there a wire that needs grounding? so it thinks its a manual ecu? (i remember somthing along the lines of this)

This could be interesting. The extra capacity of the 25 might create an issue with the early 90's (I'm presuming pre '95) 22's ECU with idle... Best to run it with a post '95 ECU and wiring.

Or do as some have done on USMB and slap some EJ22 heads and matching (to ECU and wiring) intake on it to create a frakenmotor. Apparently the pre '95 EJ22 ECU will handle this ok unless you then slap on some modified cams...

There is a wire in there somewhere that needs to be ground. Have a look at the EJ into L series how to thread in the conversions section, there's a link to ben's wiring diagrams in there that I used when I cut down my wiring harness

ok so im almost done with my wiring, but need a little help..

from the ecu plugs im guessing i can completely remove are;
-atmo sensor
-state id (for cali i guess)
-park switch
-the 2 air con wires
-neutral switch
these are all i have from the ecu that im not 100% sure about

i have 2 wires from sensors, 1 on the block the other 1 on the water cross over. which i have not attached, im guessing they need to be tapped in? they are the single pronged sensors see pic below VVV

since im using ej22 wirng on this engine on this engine i had to pull the intake wiring off a car at upullit and because of this the IAC valve plug wiring was chopped off!!!!
so can some one with a ej22 tell me which colour goes to which pin in the IAC plug? below are my ej22 loom side and the ej25 plug which is the same but the colours are not the same VVV
ej22 loom

ej25 plug

ok fuel pump relay...
thick yellow is constant power
thick black? does this run to the pump?
green comes form ecu
and at a guess thin yellow wire needs switched power, not constant?

and last question (im sure there will be more)
powering, i have reread the ea2ej pdf and amstill scratching my head.
i have done this conversion before but have not had the fuel pump working?
so what im thinking is....
the thick yellow wires to the ing'relay and back up power need constant power.
the black is a ground
the think yellows with red stripe supply power when the loom/ecu when the relay clicks over
and the light green is what makes it all happen? (this im not sure on) so this needs to be tied in with the "ON" position of my ing'switch in the car? VVV

i would like to atleast have spark before the weekend

thanks

The air con wires you don't need, even if you've got AC - apparently the ECU will alter the idle without being triggered to.
I don't know what an atmo sensor is. Nor the state id.
Park switch might be the one that needs to be grounded if it is an auto ECU. I don't think I did anything with the neutral switch...

Both of these are temp sensors - one is the EJ and will be in the wiring loom with a matching plug, the other is the temp gauge sensor. If you have the time/energy now is a great opportunity to have the factory sensor unit that came in your ride fitted to this coolant crossover pipe - this way your temp gauge will read as it used to. You will need to drill a larger hole then tap it to suit the thread of the sensor.

Sorry can't help with the IAC as I'm no where near my now stranded subi

the black wire with red stripe is the power to the fuel pump. Ground the other side of the pump's wiring or have that wire run back to an earth on the loom.
The thin yellow wire I believe is a power wire from the ignition.

From the pic below I have in that little fuse panel from top to bottom: Constant Power, ignition trigger wire (ignition "ON" for power, yellow with two silver dots), Power to fuel pump and start circuit wire. No power to the green wire.

So what you have in your pic:

^ thick yellow wires are constant power.
Thick yellow wires with red stripe are triggered power to other parts of the loom, leave as they are.
Black wire is earth.
Green wire is power triggered by ECU - so should still be wired into the ECU and not cut loose!

This should sort you out!

thanks, i sorted this while waiting on replys.
spark at all 4 plugs

so the ej22 sensors and wiring seem like they will work.
the only thing i need confirmed is the IAC valve plug before i tape that section up and tie it to the intake.

shuffbag · Post by **shuffbag** » Sun Jan 15, 2012 8:42 pm

so ej25 wasnt running as i hoped on the ej22 wiring and sensors.
i bought a liberty for a manual box, so im slotting the ej22 and matching box in together.... well its in, rear gearbox mount made, engine and box spaced 25mm down to clear the bonnet and shifter linkages modifyed to suit.

so all i have to do now is get rx drive shafts and lengthen a MY tail shaft (couldnt be bothered with a two peice shaft.

Did it run at all?? It should have by all means, unless the ECU was from an early liberty.

From what I've read the early liberty - Gen1's ECU should run the EJ25 ok, apparently the injectors are the same size between the 22 and the 25. The Gen1's don't do so well when you whack the EJ22 heads on them to make a frankenmotor...

Did the EJ25 run before you got it?

The rest of the project sounds like it's going to be good

Cheers

i did have it running, and if i stuck with it i could have made it work. But i bought a donor liberty and this way is easier.

Ive got a 98 forester so down the track if the engine fails i'll have a spare engine to throw in
