Hi Stuart
I had the 4.2 diesel and while it was a great beast, there is no comparison power wise. I even had a 2 1/2" system and extractors and while it went well for a non-turbo, was s- l- o- w. The 3.0TD GU has a heap more power (except just off idle). When towing my 1.6T van, the cruise control maintains 100 kmhr / 5th gear on small hills where the cruiser would need to drop to 4th and struggle at 80 km/hr.
As for consumption, nothing beats a comparison by the same driver - evens out the different driving styles. My GU now gets 11.9 l/100km vs 12.5 l/100km for the cruiser (speedo corrected by Garmin GPS V).
When towing, the difference is 15.7 for the GU and 17.5 for the cruiser - and thats with the extra power, far more relaxed towing having extra power on hand. I have recorded every drop of fuel I have ever purchased (I know - a bit pedantic, but us engineers love numbers) and my fuel figures are from a cruiser that has done 300,000 while the GU has now clocked over 11,500kms.
As for "no substitute for cubic inches", please check out how an F1 racing car of 1.5 litres with turbo has some 1,000HP while only 750 HP for the 3.0 litre non-turbo engine. Might be a nice catch phrase, but not really true these days with technology.
And that is perhaps the fundermental difference of the 3.0TD. It is a high tech engine that produces far more power per litre than most diesels. Yes, its had a few teething problems but thats the price of progress.
Remember the first cruiser 1HZ turbo, dropped big ends all the time and was finally repalced in 1994 with the 4 valve per cylinder turbo. Took Toyota some time to "admit" to the problem and then fix it. Nissan is in a similair boat now.
Like most new models, there are always teething problems that should have been ironed out before release, but cheaper for the manufacturer to use the buying public as their R & D and cop a few warranty claims. Hence my comment that the series III is a more sorted engine.
I will get off my soap box now.
Cheers
Captain
