A month ago or so, I managed to find a rare engine and bought the thing. It's the QSB4.5-30 which was made in 2004 and came from a genset. The guy I got it from picked it up for another project but decided to go another direction.
Here it is the day I got it.

The previous owner told me the previous, previous owner took it apart and loosely put it back together. I confirmed this today by tearing it down in anticipation for a VE pump swap.
Here is some proof.

Yikes.

I swapped the timing cover with one off a 1st gen 6BT. While in there, I made a KDP tab.

And I got it timed right.

The injection pump I found is coming from China, of course. It has a part number of 0460424326 which is from a Chinese 4BTA found in buses. Their engine model is EQB125-20. The pump's Bosch number shows as VE4/12F1400R866-8. That should be a standard on road pump. The kicker is that it is brand new (we shall see about that) and I paid $706 + taxes for it. I felt really good about that. When it shows up, I will post up some pics.
I believe the VE lines and VP have 12mm delivery valves so I should be ok there.
I have some questions about the injectors for this engine. Do you think I will be able to use the VP-30 injectors? They are part number 0432133773 which the internet pulls up 3964919. I can't seem to find any details about the angles or pattern.
Also, are there any measurements you want me to take on this engine before I put it back together?
