What turbo did you put on this d1305?
I believe that's just a timing adjustment on those pumps. The fuel screw is lower rear of pump.
So you've already done injectors?
Loosen the hold down bolts and rotate it? If that's how everything is fastened to the pump body. I don't have experience with that particular engine, but most smaller stuff has the pump body casting integrated
Just out of curiosity is this engine in a tractor? If not, what is it in? What is the goal with it?
It’s in a zero turn mower, a Kubota zd331 with 72” deck, and the goal is fun. I’ve decided to put it to pasture and use it as a spare mower if needed so it’s of no consequence to me if it breaks. Lemme tell you, this thing walks the dog on my two Ferris mowers with the 40hp vanguards.
I wonder if those other turbos you ran would work on the smaller .9L that comes in the Bx tractors? I thought about putting some altitude compensation on my bx2370

Life for an engine in a zero turn must be different. My B2650 has a D1305 in it and 99.9% of the time I’m having trouble keeping it happy with enough load. It’s a very undersquare engine that has insane torque for it’s size; the only time mine ever sees more than 1800rpm or so is when I need a specific pto speed like mowing grass.
Yep, it’s a little monster for sure. From what I understand it’s a D1105 with longer stroke. They rev them to 3150rpm in the zero turns. It had power naturally aspirated I just felt like putting the turbo for the heck of it. I’ve for sure got this little motor at its limits being it’s at 31hp factory so with an added 10psi I’m asking a lot of it.
Better stock up on head gaskets.
