Thread: 4BD1 performance

60 000kays, without a hitch, just a new starter motor $398, but that was off the old NA, so 420 000kays on that!.......
..........If I turn the screw, I'll loose some economy, and with diesel set to get to $2 a litre soon.........

You'll only lose economy if you drive everywhere faster.
Most driving is at part load, so changing the max power where you only run a few percent of the time makes no noticable difference to economy.

The best fuel saving device is still a block under the pedal.

How many kays you done now JC?

G'day Matt.
How was the trip back?
We're off to Nugent tomorrow for a look...Not enough rain lately though to make it as interesting as last time stooge and his associates went there...

I had to put some fuel in at about 900k, but I'm guessing as my Odo isn't working properly ATM. It was Wednesday when I put diesel in it!!
I'm guessing aroound 12l/100k.

Hope you get that turbo on the 120 soon..

Sorry mate, I just don't see the point of the adjustment unless you're after more power, which would be difficult not to use!......

For sure. But due to government imposed speed limits, I can only use all my extra power on hills and in short bursts. It hasn't changed my overall fuel consumption, but tyre consumption has definitely increased.

engine had been running way too cool

don't fit it without a new gasket however

how cool is to cool ?????
