3 litre Patrol

Rob,

The torque delivery of the 4.2 is alot lower in the rev range and more usable off road. I have the old 4.2 non intercooled and my mate has the 3lt and mine is all over his low down in the scrub just idles where he has to rev and travel faster do overcome the same obsticles.

Regards

Yes these "maximum" specs that people LOVE to quote on here and in general really don't mean alot.
Some motors are very peaky and will generate high kw or torque for a short period of time whereas a competing engine may have a lower "maximum" but be able to sustain it for longer throughout the rev range.
These new DID motors are very good and they do generate vast amounts of torque and power but the bigger motor is going to generate similar amounts of power in a more steady way.

You look at the little petrol motors that generate the same "maximum" KW as my Turbo Diesel or more Kw than mine, and yet for some strange reason I'm idling over obsitcals and these guys are taking run ups.

Hi Rob

I have the 3.0TD with the Dtronic so it now has 420Nm of torque @ 2,000rpm. But at idle revs my old 1HZ non-turbo 80 series has HEAPS more torque even though it has significantly less max torque (274Nm max @ ~2200rpm).

But once the 3.0TD is at ~1100 rpm it has more torque than the 1HZ and as revs increase the difference becomes huge. It takes a few revs for the turbo to spool up so at idle the 3.0TD is effectively a low compression (17:1) "non turbo" 3 litre compared to the 4.2 high compression (22:1) diesel. At these revs there is no substitute for capacity!

Hi All One of the main points that we dont seem to consider is that the turbo 2.8 and 3 ltr turbos is the size of the gearbox , I had the 2.8 heaps of power once the revs were up, and when I asked the dealer about the gearbox he said it was inbetween a Navara and the Patrol although I never had any problems with it,although after 120000 ks, a lot towing a quiet a heavy van , the box was starting to make some noises out on the highway, If had my time over again I would have gone for the heavier box . Hope this helps Catchy snr

Hi Muzzumbigie,
My 3.0L has the same problem,I suspect that it could be a faulty or stuffed ERG valve, I'm going to check mine out this weekend -I Hope.
Cheers
