    Another 1HZ DIY turbo conversion.... ALL DIY not a kit...

    It is probably doable... I don't have any experience with 1HD-FTE. My engine is 1HZ and it has no ECU, so getting rid of EGR is an easy task.... mine actually came without EGR from the factory.

    1. Yes, by max power I meant max fuel, which is at the most aggressive curve. 2. "I've found that you can also fine-tune the pump by adjusting the spring tension that sits below the aneroid pin." My guess is you mean boost compensator star wheel adjustment. My star wheel is all the way at the...

    Another 1HZ DIY turbo conversion.... ALL DIY not a kit...

    This was discussed over and over... The weaknesses of the non turbo 1HZ and other non turbo engines are well known. The problem is people themselves. We get a slug like 1HZ and I mean this.... my pre turbo 1HZ was a slug... We get a magic pill called turbo.... we try it and we LOVE it and we...

    Another 1HZ DIY turbo conversion.... ALL DIY not a kit...

    Finally we had a good chance to test out truck on mountain roads. We actually drove to over 7000 feet elevation (2200 m). The pressure on my boost gauge was -3.4 psi before starting the engine and it was the same -3.4 at idle. The boost was much lower and getting positive numbers at much higher...

    A bit off topic but this can be handy for someone. As I mentioned before I drilled through AC condenser by mistake and had to weld it... This trucks have side glass and this makes charging AC and checking AC performance much easier. I pressure tested first and then vacuumed my system with...

    I finally started to like driving my truck.... My other vehicle is tuned Ram Ecodiesel with 300 hp and driving my 1HZ was always a slow torture... It is still far from matching the power but it is definitely much more enjoyable right now and I think I can still add more fuel as my EGTs are...

    I forgot to mention. I don't limit my boost pressure right now. I want to limit my fuel but have as much air as turbo can blow. I am not 100% sure if I am correct.

    Another 1HZ DIY turbo conversion.... ALL DIY not a kit...

    Right now I am still trying to set up my fuel. As I understand it is better to be on lower side than to add too much fuel and burn the piston. Unfortunately I don't have any dyno equipment anywhere close, so I have to do it by eye. The power is much better and I think I still have some room for...

    Here is very well written article about fuel tuning of our diesels. https://www.tillix.com.au/mechanical-diesel-engine-tuning/ Very simple and very detailed.

    Thanks for advice, I will try this tomorrow. With AFR and pre turbo EGT I can afford to play with these screws a bit :)

    Another 1HZ DIY turbo conversion.... ALL DIY not a kit...

    So, I am leaving fuel pin in whatever position for now. It doesn't affect idle anyways because there is no boost at idle. I slowly turn max fuel screw until the idle start to climb and this is the indication that I am close to its correct position. I adjust idle screw to have proper idle. At...

    Another 1HZ DIY turbo conversion.... ALL DIY not a kit...

    The new boost comp is coming without idle screw, no max fuel screw and fuel pin in who knows what position. I marked max and min points on fuel pin diaphragm, so I don't need to pull it out. Right now: 1. my fuel pin in max position 2. Idle screw just touches the throttle link 3. Max...

    Another 1HZ DIY turbo conversion.... ALL DIY not a kit...

    This question is addressed to someone who knows the tuning. Right now my idle screw is way out, the truck starts but runs at very low rpm. Can I screw the fuel screw in until my idle starts to rise or it will be too much fuel? Can this be the start point? My fuel pin (the one with diaphragm)...

    1HZ EGTs

    No wonder.... you push more air and add more fuel to get more power... More air = cooler EGTs. As long as you don't add too much fuel you have more power and cooler EGTs. Without turbo to get more power you add more fuel your AFR drops and your EGTs are climbing... you keep choking it with...
