So gathering parts to swap my 1950 International delivery van. Have the engine out of a carrier reefer, 5 speed Toyota trans and adpterplate so far, so now I’m piecing together the smaller stuff. I’ve searched around quite a bit the past few days without much luck on things like:

- alternator to use? Would preferably like to keep it the stock V belt. Being an older car the alternator is the only thing being added to the accessory drive. No AC, power steering, brakes, etc.

- do I need to put in an electric pusher pump for the fuel feed line? It seems like the back of the injection pump has a lift pump built in?

- is there any aftermarket or OEM source for a exhaust manifold that exits downward? Will be adding a K03 turbo

- I got my adapter plate from kubotaswappers, came with a modified turbo Toyota flywheel I’m having a hard time finding the right clutch pack for it, been through 4 with the local auto parts store so far. Anyone else have that adapter plate/flywheel and have a part number handy for a clutch kit? Flywheel is a LUK part number LFW207. I’ve messaged him about it but not heard back yet.

- factory manual with wiring diagrams/parts numbers/service procedures are always good to have.

- also is there a thread about engine modifications/tuning anywhere? I’ve seen mentions of governor spring and other adjustments but nothing on results and how to do them. I’m used to working on P Pump Cummins and this injection pump seems even simpler by the looks of it.

 

Found the parts books and service manuals online and believe I got a one wire alternator I can make work with a home brew bracket. Still researching everything else if anyone can chime in....

 

Hi , nice to see another Kubota swap out there! You definitely need to replace the gov spring with a very stiff one and remove the shims under the injection pump. I have no info on the clutch as I have not used the Toyota trans. The turbo manifolds are limited, I have used the V2003 manifold and like it the best but doesn't dump downward. I'll PM you with my phone # so I can help you out in detail.

 

Got your PM with your number, I really appreciate that. When are good times to give you a call?

I think I’ve got a handle on the governor spring and timing shims after reading through the service manual.

Ive got the clutch sorted out after looking at 6 different ones with the parts store guys over the past few days. Picked up a simple one wire alternator as well to put on the engine.

 

I've been reading through usedkubotaman's ranger swap thread and am intrigued by how he increased fuel output by adjusting the delivery barrels somehow. Any one have any more info on the procedure for that?

 

The "Carrier" spec Kubota's had different injection pumps that delivered more fuel than the other Kubota motors, The one he used was a Bobcat motor. All of mine deliver way more fuel than I need so I don't have all the fuel turned up. I forgot to mention that no additional fuel pump is needed as the engine mounted lift pump is sufficient. You can call me most any time, if I'm not available I"ll call you back, text is ok.

 

Good to know. I picked up a heavier governor spring at the hardware store and think I have pretty much everything else I need besides some fuel hose, fittings and misc. gaskets most likely. K03 turbo and motor mounts are in the mail.

Time to start pulling the old International straight 6 and start mocking things up. For now I’m probably just going to get it running without an inter cooler for the time being. Does anyone have rough dimensions of the Volvlo inter cooler I keep reading about? I plan on using one of those so I’ll need to know how much extra space to leave behind the sock radiator when I do end up putting one in.

 

On the gov spring, I wish I would have put in a stiffer one than I have now because it has stretched a bit since installed. Now it de-fuels @ 2400rpm. I had the truck on the dyno and it was continuing to build HP up to that point, TQ peaked @ 2150. 81.62hp/190.69TQ. That's to the ground, I fell that I would have had more HP if the gov spring would have been stiffer. Also it's starting to mess with the cruise control, I think the looseness of the spring is making the throttle surge at lower speed {under 65 mph}.It needs to be longer to compensate for the extra stiffness. Cool build, I'd like to see pixs. On the IC, I;m running a factory Mitsubishi Evo, second one I have run. Seems like most of us with success have run factory units v/s e-bay units.

 

Something else I should mention, if you're planning on revving it over 3000 rpm and making over 25psi boost then I would recommend shimming or replacing your valve springs for more seat pressure. I find that my valves float when revving over 3000rpm and the boost will also overcome the valve springs with high boost. I rarely rev over 2500rpm and boost over 20psi, but I still wish I had done that. Maybe down the road I will.

 

I put the new governor spring in the other day and I think it will be plenty compared to the stock one. I had a hell of a time getting it hooked back on with the strength of it. I'm not planning on going over 3k RPM or more than 18-20 psi of boost, if those plans change though I'll look into springs with more seat pressure.

Got a used K03 turbo for cheap, just had a broken stud on the exhaust outlet flange that will be easy to remove. Also picked up weld flanges for both exhaust inlet and outlets so I can fab an adapter plate and down pipe. Other small pieces that have shown up include misc. gaskets, new thermostat and motor mount bushings. All I think is left would be an RPM, EGT and boost gauges. Wasn't able to pull any of the old powertrain out of the van yet, had to take it to an event today, but it will be full speed ahead after that.

Another thing that came through mind mind was how to clean the old gas tank and prep it for having diesel in it now. I've never changed fuel types with an engine swap but know this needs to be done. Drain all the old gas and just flush with fresh diesel a few times? Is there a specific product to use? Its only a 15 gallon tank, if that.
