The fuel loss at higher rpm is the cross coupling pushing and limiting the plunger as the rpm increase. The reason how diesel engines rev limit. So you either make them lighter somehow or prevent them from pushing/limiting the governor with the risk of too high rpm limit

Hey mate, do you know what the 2 timing marks on the harmonic balancer line up with (the ones 10mm apart? Is one for timing? And one for injection? I’ve seen they line up with the timing belt cover when at bdc

Any footage of after you built it, cheers Graham

Best and most informative video ... Cool. Thx man. You helpt me a lot

I’ve got a question about the manual glow switch. So I have d22 navara that was running a zd30 but is now qd32t and fully mechanical. I checked the pin outs and 111 and 16 do the exact same thing as on the rd ecu. My question is does the switch go in between the non ecu side of 111 and non ecu side of 16? Or ecu side of 111 and non ecu side of 16 (or visa versa). Can’t image in being switched on the ecu end with both wires or am I tripping?

Brilliant, thanks for making this 👍

Good onya Aussie. I’m looking into this for specifically, possible cleaning diesel 1HZ after running waste veg oil as ⛽️ fuel. N\A. Never heard of it before that was a good detailed instruction and well explained. Makes sense in terms of cleaning carbon ect at high temperatures if introduced as if you ever fry on a hotplate and it gets carbon and generally dirty, splash 💦 a cup water on the plate while very hot and the crap comes straight off much easier. WVO ppl often talk about gummed up rings, bores and glazing etc. Often thats if not start stop warming up on diesel before switching to wvo or SVO. Interesting.

Great vid. Although the spring for the diaphragm being less tensioned will cause more fuel to be injected at lower boost pressure increasing smoke as boost starts to come on. Increasing spring tension will delay extra fuel cleaning up the smoke as boost is coming on. Getting the engine to lightly soot as the engine comes on boost would be ideal, then adjust the boost compensator diaphragm to allow more fuel in on boost. Then finally add fuel throughout the whole rev range via the fuel screw to increase power.

Good video, thank you. I have a question on something that isn't yet clear to me, if you could: How do I know which orientation to set the fuel pin for increase/decrease in fuel? Thanks

Yeeeah, this is a bit much for me at my level. >.< Any suggestions for a bolt-on part? To confirm, '98 GU.

hey, you seem knowledgeable, so heres my question: i took the body off of my 1999 4runner manual with the 3rz. i want to put a random car body on it dont care for any guauges. all i want to know is what wires do i need to send positiv 12v to to make the engine run ? right now its sitting motor and frame with all the wiring pulled out of the cab. id like to have it start and drive as a chassis+motor as is

Does the timing of a VE pump work like a distributor on a petrol engine? Because what I know with a distributor on a gasoline engine You can adjust the max timing BTDC at x amount of rpm Is that important with diesel injection timing

Hello! I really liked it! If I understand correctly, it is easier and more convenient to remake the Patrol GK, that is, replace the 11mm plunger. And then you don’t have to look for the idle speed cable and the gas pedal. And there is no unnecessary electronics there. Thank you friend!

Hey mate I pulled boost pin out and now conveyor pin is in the cylinder blocking where the boost pin goes, how do I move it?

Hello, what is the sequence of the injector pipes in the Nissan patrol RD28 injection pump?

Do you have experience with the sd33t?

Hey mate i just built my 9-11mm pump but i have all the machinery shit on the side do i need it or not like im talking about all the stuff on the side and other side of the pump

Has this been tuned or anything coz mine is so sluggish from take off

Does this applies for this rd28eti as well?

Hola me gustaría saber cómo puedo hacer que el turbo silbe de esa manera, tengo un Mitsubishi montero 2.8 pero yo no oigo silbar el turbo cuando conduzco.

Going to start this shortly and this is new territory for me. This video will help massively, cheers 😊

Hello, could you help me? I cannot remove the conical piece that goes along with the membrane in a 1999 Mitsubishi Montero. It is possible to remove the membrane nut and access the inside of the area to unclog the cone, the plunger, and raise it. up to restore order, the car works perfectly in low and high speeds, perhaps to recover when changing gears and going up, it's a little bit missing but the car works perfectly, it's great. I bought it recently and now I wanted to readjust the diesel injection, I can't, you can help me? Thank you thank you very much.

Great video dude! Solid work!

Mate you're a really great teacher. You taught in a really practical way so people understand what's really happening and even provided a practical method for seeing those changes in real time. Love your work

My 2.8l GQ got 320,000 ks and the original clutch which really needs changing badly. I purchase from a interstate truck driver he taught three of his four daughters how to drive in it one just couldn't get the gears my son to drive in it. Cheers Graham

I had bad leak in GQ pump. I purchase kit to rebuild it and pulled the pump off and started pulling it away and my nephew said you're crazy. He is mechanic and told me to take it to a diesel mechanic. I doubted myself and took it to a diesel mechanic gave me a price to fit new seals but then a few days later said the whole pump needs rebuilding. When I picked up the pump they said oh for the $200 more we would have taken the pump off the car and put it back on for you so as I struggled to put it back on I was pissed off, all that time dicking away. With the plunger couldn't you have just drilled out the 9 mm to take the 11 mm? Cheers Graham

Interesting video mate. I got a 96 gq 2.8 with turbo. What would be a safe boost increase. I don't want go silly. It all stock, I'm the second owner. 320k. I had the pump rebuild in 2020 as it was leaking. Turbo looks really oily, wet black look. I don't even know if it working. I use to just be able hear it on a quiet day. Do U think he221w would help? Cheers Graham

That's gangstaa

This was going smoothly for me until my tap snapped off in the block. I am trying to think through how to remove the metal shavings that are in the oil galley. Any idea how to flush that properly? My engine is out of the truck and the head is off.

Very very good video on wiring this is just what i needed thank you.

This helps so much on my 3.4 swap 🙏

Top info, Cheers.

what's your estimated hp?

Hey mate Have you ever tried the gu injectors with the gq pump on the car because I am wondering if the gu injectors are the problem side note they have both injectors and pump been rebuilt. The problem is I can’t turn the fuel down without the car wanting to stall

Need your email buddy

Hey mate have you ever had any issues with the low range 4wd bc my front wheels don’t get much torque or spin when off road have done new diff centre axels and swivel hubs + new locking hubs any ideas ?

Awesome job mate!

My stock garret turbo you can hear whistle on idle, it only hits 15psi it must of been high flowed dunno but I feel like it generates alot of heat

If you run two pumps inline to a Y piece you should be able to double pressure

Hey mate got an update on the turbo

Missed oppotunity to replace the clutch...

3rz Engine keem c.hen

Как я понял идея с коллектором и турбиной HE221W была взята у меня.

Who did you get your turbo from?

Hey mate my gq rd28 keep smoking at idle and when i rev it it pisses out with smoke what do i do?

Hey mate, just checked out your video and you said to reach out if we had any questions about the 4x4 add from the 3.0 to 3.4. Let me know how I could contact you. Cheers

Is the governor the only thing I need to look at to know a second hand pump will run okay

How big is the pump love the rd28 videos learned alot

Why those rd28t have always that roughly smokey cold start? Mine does to, and everything is in perfect condition

Good job
