Hi, from what I have heard, the best mob in Australia are Brunswick Diesels. They should be able to answer your questions. Hope this helps, Bill Church

I have a 6.5 in a GQ ute and it has heaps of everything that you could want out of a motor!! Power +++ and is not bad on fuel, I manage to get 900km + to 140 litre. It cruises on 100-110kmh and off road there is very little that comes close to the torque and power to get you through the nasty stuff. It does take a little getting used to the extra power and in soft sand you need to be a little less aggressive on the pedal. If you have the money to spare I would recommed it without question.

Brett,I believe the 6.5 chev redlines at around 3000rpm. Did you have to change diff/gearbox ratios or just whack on larger tyres? I'm thinking off this mod myself but it is quite expensive and if it necessary to change diff ratios then it may be too much. I assume you had a 4.2 diesel in the GQ, how is the acceleration for overtaking on highway compared to the old motor. Also did you get the turbo-ed 6.5?

Hi Simon, i have a patrol with the 4.2, looked at the chevy conv. i liked every thing i saw but didnt like the noise in the cab, they are a very rattly deisel. I ended up fitting a supercharger to the 4.2 and got what i wanted in power and torgue, more than i expected, very much like driveing a big petrol, they start working right from idle, and all parts are carried by holden dealers. Worth while looking into. Col

Hi Tony,
Colin is right the 6.5 does make a bit of noise but that is a small price to pay for the performance that you gain with the larger motor. I up graded my sound system and don't realy notice the extra noise much at all.
I only have the 6.5 without the turbo but the compared to the 4.2 it isn't a competition. She does redline at 3400rpm but I have never really needed to push it higher than about 2800rpm as the motor is so torquie that I just haven't found the need.
No I have not needed to change the diffs but I am in the process of buying larger OD tyres.
The motor has been in the car for about 2 years and done over 100,000 km in that time and I believe it has been worth every cent.
