I don't even care about turbo'ing a 1HZ but I did enjoy listening to this Aussie bloke talk about diesels and how to do them right. I think all online instruction should be by Aussie-accented speakers, lol.
He might find it goes faster if he lets the engine rev above 3000. Why change up to overdrive at 80 when trying to accelerate? For kicks, I took my non-turbo HZJ80 out this morning and measured how long it took me to get to 100km/h. From a dead stop, without revving the engine before take-off, with my heavy steel bull bar, winch, second spare tyre, a back full of gear, and four passengers, I measured 0 to 100 in 19 seconds flat. Dude needs to learn how to drive stick.
