Unfortunately I imported a very beat pajero. Has 90xxx km and crazy amount of blow by and top end noise. Also may have some
Bottom end. I’m in Canada and looking for some thing to swap in or if some one could send me in the right direction for getting engine parts. We do have the 4g94 in lancers but it’s not gdi. Can this computer run that or am I going to be splicing the lancer pcm into the pajero to make it run?

I've always wondered why...

I've always wondered what the Canadian "fascination" with used JDM vehicles was, given the variety of vehicles readily available, why is it that you go out and buy the "headache" that a used JDM vehicle will inevitably turn out to be.

Before you get too enamoured of the Lancer 4G94 swap, I suggest you take a close look at the cylinder head & pay attention to which side of the head the manifolds are on - I don't remember where I came across it but I believe the Lancer head has the manifolds swapped compared to the iO head, so there may be physical challenges to the swap, also pay attention to the engine mounts - the iO uses a conventional mount system with left & right mounts mid way down the block, I'm fairly certain the Lancer is different and has a mount on what would be the front of the engine block on the iO - make sure the block has the holes drilled & tapped.

I also expect there to be electrical/electronic challenges - no the GDI ECU won't run the MPI engine (or vice versa) - and trying to swap the engine along with the ECU will bring other challenges with things like the automatic transmission controller, drive by wire throttle etc., so way more complex than just a simple re-wiring job.

Parts.

Megazip.net and/or amayama.com should have most of what you need for a re-build - if you're lucky (as I was), you won't need a re-bore & oversized pistons, I think you'll find that the rings & bearings interchange between the GDI & MPI 4G94 engines, rebuild gasket sets will be very different and pay attention to what style cam/rocker covers your engine has - I'm not certain about the 4G94, but the I know the 4G93 has two different styles a "one-piece" metal cover or a "two-piece" plastic one - the gaskets used are different.

You should be able to enter the vehicle's frame number (VIN) into the two websites and have them select the correct parts catalog, doing it that way reduces the chance of getting the wrong part.

My problem wasn't blowby perse, but wildly varying and ridiculously high oil consumption (as much as a quart of oil in a few hundred miles) - the problem turned out to be stuck oil rings, I suspect because of a lack of routine maintenance.

Good luck.

Honestly I wanted a little 2

Honestly I wanted a little 2 door 4x4 and that’s pretty hard to find around here most of those have rusted right out.

Yeah you’re probably right with the mounts being a lancer is a fwd. I’ll do some poking at the wreckers but if I do swap it would probably end up with two stand alone pcms one for the engine and the other for the tranny. Doubt it’ll be a fun time making fake inputs.

I feel like there’s a good chance this thing is going to sit in a field till I get the grinder out and put a v6 from a chev in it.

I really can't comment on availability, but speaking as the owner of multiple Suzuki 4x4s and also a used JDM Pajero iO, you might have been better off with a Suzuki Vitara or Chevy Tracker, they're a heck of a lot easier to find parts for, both regular spares and also things like springs & shocks/struts if you plan on lifting or other modifications.

Regardless of make & model, sourcing spares and service documentation for used JDM vehicles has it's challenges.

I don't quite think it works that way, but don't let me stop you from trying.  Both the Lancer & the Pajero should have separate ECU & TCU modules - they are not quite stand alone as some degree of communication (I believe throttle position) is required - but maybe they use a common protocol.

Not a bad idea but take a look at the engine installation from underneath - the engine isn't mounted to the frame rails - it sits on the front suspension crossmember - you might end up having to re-engineer the front suspension as well.

Figured I would give an

Figured I would give an update. I found out the noise I thought was blow by was actually pulling vacuum from the oil fill cap. I’m guessing that’s just from the crank moving around in there. I have never played on a inline 4 before so the noise scared me but it appears to be normal operation from what I can tell.
