Mitsubishi 4D34

[FL cruiser]

Mitsubishi 4D34. Has anyone put one in a Cruiser?
Do these engines have a good reputation?

Compared to an Isuzu 4BD2T, it's the same size, weight and has exact same horsepower specs at 130HP. I haven't compared torque specs yet.

One of these days I'll take the bell housing of of the Mitsubishi and see if it goes on the Isuzu. It would be nice if the engine blocks had the same bolt pattern. If so, maybe the Isuzupartswapper kit might work on the Mitsubishi. Would like to put an H55 behind it.

The turbo looks almost identical to the T25 that's on the 4BD2. But aside from that it looks like nothing will interchange.

Mitsubishi diesels don't seem to have much of a fan club. I've been less than impressed with the smaller ones.

I think the Canter engines are ok,they certainly sell well here.
103kw and 365Nm at 2900rpm doesnt sound too bad.
Canter 4WD FG649

There could be some hidden potential in these type of engines

FL cruiser,are they tall like a Cummins 4BT?

That big filter box in the top pic would look cool strapped to the front of a 60 series

How big is the 4D34 ? is it the 2,8 liter? I owned a mitsubiatchy L300 4x4 van. Fantastic vehicle... But the engines are a mess...Mine would go warm very fast.. At any time there must be dousins of people looking for heads for these.. they are dinky little aluminium heads that warp badly when cooked. This was the 2,5 4D56 though. Some of them run for 400 k km though.. But those are owned by mantanaince and oil-check enthusiasts.

A friend of mine who runs a machine-shop do some enginehead straightening now and then. He says apart from old US v8' that really dont have any flat surfaces, he gets mainly two different engines.. the
4D56 from mitsu .... and the poor little 1,6 vw diesel from back in the days...and they have an excuse, being a miesly 1,6 mounted to a huge 4 wheel drive van and pulling builders stuff around.

Sorry.. this got a bit off-topic. The bottom line
I'm never getting a mitsubishi again

Or on the side of a 45 pickup with a snorkle.

Although I haven't compared measurements, I don't think they're quite as tall as the Cummins.

The 4D34 is a 3.9 liter.

I think I'll lean toward using the Isuzu even though it isn't as in good of condition.
Nothing a rebuild can't solve.

Starting to get engine swap fever.

I had no background on the engines. I figured I had better check the condition of them before going forward.
Did a compression check on the Mitsubishi. All cylinders were equal at 340PSI. Glow plugs concerned me because they were covered in oil, but figured it could have been rolled around and possibly up side down. It fired up fairly easily and ran great.

The Isuzu looked like it hadn't run in years. Turbo was frozen, leaves and dirt in every opening of the engine, dirt an gritty oil in the engine. It took a long time to get started. I was just amazed it did actually run and didn't have any knocks. First it ran on two cylinders and eventually on three. Oil filter had a hole in it and puked oil all over the floor in the garage, so couldn't run it too long. It obviously should have a tear down and rebuild before being used. Too bad, it would have been the easiest to install with the available adapters being sold, available parts and all the info available on the net.

Looks like the Mitsubishi is the best candidate.

The Mitsubishi is turning out to be the challenging. though. Thought I would post up here to see if there is anyone that has any Mitsubishi info at all or know where to find it. So far many, many hours of searching the internet has turned up anything. The dealer doesn't even stock any manuals, and so far I've been to cheap to order one. I did try posting on 4BT Swaps forum too.

Anyone have any bell housing info or know of anyone doing any swaps with this engine?

One mystery I'm attempting to solve. I'm trying to find some info on the Zexel inj pump.
There is a wiring harness that goes into the front of my IP (see circled below).
It has six leads coming out from it. Trying to determine what they might be, or if a computer is required for this engine. Just figured I'd check here and maybe get lucky that this might look familiar to someone.

The engine is from a 1992 Fuso FE

A friend of mine has a couple of Mitsubishi Fuso trucks. IIRC, the connector on the IP has something to do with ECU-contrilled advance. I remember him saying that when he disconnected the ecu, the truck ran ok, but not as well as when it was connected. I think he has a set of factory manuals that go into great detail on the IP, much more than do the Isuzu FSM's. Next time I see him, I'll check on the manuals. Maybe I can scan them and get them posted on MattF's site (Downloads - page: 1)

I have been told by several people that the bellhousing on the Mitsubishi has a Chrysler 727 pattern.I have a friend with a 1980-ish Dodge pickup with a factory installed Mitsubishi 6 and it uses a 727.This would be great for you.Good Luck.

That makes sense. The engine surged and sputtered somewhat after about 1500 RPM. The tag on the engine shows timing at -7 BTDC.
I guess an ECU will be required then.

I hate to see anyone go through the trouble of scanning a manual. I would feel the need to have a good bottle of rum or keg of beer shipped to your house.
I would feel guilty being to cheap to buy a manual and having someone scan their butts off. I'll just break down and order the manual when it comes that time.
A wiring schematic should suffice.
Thanks for the offer though !!!

Unfortunately I don't have a bell housing. I did check though to see if the big block Mopar manual trans bell housing would bolt to the back of the engine. It wouldn't.

I vaguely rememnber that my friend's Fuso came with a JR403 automatic transmission which is the same automatic used in Isuzu NPR's prior to 1999. The bell housing on the JR403 is a separate piece so it is possible that a different bell housing was used while still retaining the JR403 core. But then again it is possible that the two engines shared a common bell housing bolt pattern. Just a thought!

Just a guess but it looks similar to the TPS (Throttle Position Sensor) used on the Zexel inline pump on the Nissan TD4.2. Just had a look at my FSM but didn't see any TPS on the pump diagrams for the Inline Zexel or the VE. But I know all autos have them. To confirm, take a pic of the pump to your local Mitsubishi truck dealer and they can check it on their FAST software.
