Are there any performance up grades available for the 1HZ that any of you are familiar with?

Such as bigger injectors, or a different cam?

Im familiar with P.I.. A lot of people are still preaching that P.I. for a IDI is NOT a good thing. Wayne-O appears to have had good luck with his set up. The claim is that it's to hard on the CUPS.

Anything that a person can do to get more power outside of a turbo? I plan on turboing her too, but I just thought I'd ask about other things.

Thanks in advance.

More power than a 1HZ with a turbo and PI? I drove Waynes beast, it had plenty of power.

IMOP I would not need anymore power. Even before I turned on the PI it still had loads of power. Not many cruisers can sprint past 120kms and hour in a blink. With 35's. I think I let off when I was surprised when it was in the 130's. Lots of torque.

Have you gotten your truck back yet? Looking forward to hearing about how it is after the big overhaul.

No mistake Wayne-O, I was talking about improvements other than turbo PI.

Like bigger injectors, cams, etc etc etc.

Maybe with a turbo and intercooler and PI I wont have to worry about it????!!!!!

Once you know what you are doing for a turbo etc, talk to Dr. Rob in Richmond about a cam. He has a guy who can re-grind cams for better performance. Made a nice improvemnt on Rob's BJ40.

Thanks for the advice. Im surprised there there arent more mods out there considering how many trucks this engine is in world wide.

Just a suggestion, maybe try more Austrailian sites, as they have lots of those engines down there, and probably have a lot of different mods available.

Did you thing in add a intercooler without a turbo set .. ? in the way to get more fresh air into the intake . .. I think to much about that .. with it you can add more diesel in the mix .. :D

but with out the turbo you are trying to suck that amount of air through a maze of duct work which would cause the engine to work much harder to get the air it needed...
suck in a breath of air now take a shop vac hose with the same amount of force... see a difference? or no difference?

Not sure how to get enough fuel into the engine to compesnsate for that amount of booost......
You could get away from the dual setup and go with a variable geometry setup. If you have the $$$$ haha
