Sluggish Hilux 3ltr

Yes that's par for the course I think Boxa. I was passed by one on the Hume Highway at 100kph. I was towing a 17ft van and on cruise control in a Prado. Next rise I found myself catching and then passing him. I maintained 100 while he must have dropped to 80kph. It's just the lack of turbo of course and it's probably OK off road. Even the 6cyl normally aspirated diesel in the standard cruiser doesn't produce as much torque as the TD Prado (3l 4cyl). See Toyota site for figures if you are interested.

have you checked the injectors?
is it serviced regularly?
what size rubber is on it?

hi boxa,
if your bro in law lives in melbourne , tell him to call me on 87423600 (business hours)and i will give him a free sample of something that MIGHT help. if he dont live in melb still call and i will tell him where he can buy some.

TUDDY

I run a Triton piddly little 2.5 turbo diesel with manufacturers rated 62kw motor, less than a Mits. Mirage & 200nm torque @ 2000rpm . It will climb long highway hills in 5th at 100-110 kmh at about 3000rpm, & makes 135kmh plus on a good day.and about 10kmlitre at 100k,s
What rpm is the Rolux running at? This will affect the grunt particularly if it has the same diffs as the TD versions with electronics.
Wide tyres WILL reduce the performance and increase fuel consumption noticeably.
A dirty air cleaner will do the same.
Diesels take a while to free up & give their best.
Have your pump timing checked, preferably on a dyno. I am told many come out of the crate with retarded timing. My Triton was advanced a bit with benefits.
I have heard the 3.0 is a bit slow by modern standards but I am sure it will be less trouble in the long term without all the mystery gizmos.
Maybe a free flow exhaust will help allround too & dont forget to release the handbrake! Sorry, kidding.......Ian
