4g94 swap for 4g69

Hey guys and gurls! I'm fairly new to cars still and about to do an engine swap after my timing belt slipping in my 2004 CH ES lancer with a 4g94 in it.. So a legend of a friend has giving me a 4g69 out of a 2005 CH ES lancer.. My question for you gods of the lancers, how hard is this going to be? I expect it to take awhile and I have the patience and time on my hands, (money not so much).

I have the 4g69 and gearbox but nothing else really.
Will the 94 ECU work? I'm like 99.99% sure the loom is going to be different because MIVEC.
What about mounts? will I be able to re-use the 94 mounts on the 69? is the fuel pump different?

I'm doing the entire swap outside, no work shop. its just myself, a bunch of tools, youtube and lancer forums.

Plox send halp.
 
Hey mate, good on you for having a go!

You will need:
-4G69 Motor and Box complete assembly
-All 4 4G69 Motor Mounts (i will confirm via part numbers soon)
- Engine ECU to match the motor
- Engine wiring harness
- Keys to match the ECU
- 3x Door Locks to match ECU
- Ignition Barrel to match ECU
- All hoses that come off the motor and its accessories.

You may need new A/C lines, new radiator coolant lines and a new fuel feed line/line end.

You will need to keep the exhaust manifold and complete intake system.

The wiring might be a bit of a mess if you only take the engine loom. The 05 will have ABS, unlikely your 04 does.
 
Thanks man!
I'll be keeping updates on the build when I have something to report, going to take awhile from the looks of things.
As for the aircon, going to be removing that because race car the daily..
as for the transmission, can I use the 94 CVs and stuff on the 69?

I think the CV's will be the same, but the driveshafts may be different lengths. Can't find information on the G69 driveshafts as Mitsubishi never sold the CH with 2.4L in Japan and all my references only link to Japanese models. Maybe a case of trial and error? Even just have a look to see if they're even similar
 
You will also need the throttle pedal assembly as I believe 4G69 is fly-by-wire and 4G94 is cable
 
Update: Old engine is slowly coming out, didnt realize how much crap was involved in removing the loom.. found out my fuse box has ABS but of course my car doesnt have ABS.
hit a couple problems as one would when they decide to do their first ever engine swap, like, how the *fudge* do you get to the starter motor part of the loom as thats the last bit still connected on the engine side of the loom.
I'll have a list of stuff thats been done, needs to be done, parts list, and how many times I've said "Why the *fudge* am I doing this".

Update.
Removal has been on a standstill for this week, require a couple tools I have some how lost. oh and of course this *fudge*ing rain I've had this weekend isn't helping at all.
Engine mounts you only need to get a front mount and right mount, the rest of them will fit the 69 and 94 engines.
Drive shafts are going to need replacing, regardless if I could use them (no you cannot use a 94 drive shaft in a 69).
As for the keys and key barrels stuff, it possible to just have your key flashed to suit the 69 ecu, roughly the same price if not cheaper for a key flash than it is for a new key kit.
 
It may be possible to edit the imob code in the ecu. I know its possible with 4G94 ecu to change the code or remove the imob entirely. You would need ecu flash and a tactrix.
 
Hi Deano, how did you go mate?

I did my first engine swap 1 year ago (almost exactly), on the same engine and same car, same colour even!!
BUT I was ditching my old 4G94 for a another 4G94, direct swap. Same for same, since I had never done it before.
Even then I till had my own, "why the fudge am I doing this" moments.
But I can say, huge feeling of accomplishment when it was done, and we have just ticked over 15K kms on the replacement engine with zero issues.

After I completed that, I started to think about more performance based engine swaps, once this car is no longer the one we need to relay on for our general family transportation.
So I was thinking a 4G69 myself.
Keen to hear how you get on mate.
