Suggestions Wanted - Crewman X6 VZ - want to improve towing

[toost11]

Just wondering if I can have a few suggestions to improve the towing on my Creman VZ X6. I did a lot of long distance this year towing 2000kg around (with a loaded ute) and the car went really quite well. I'd just like to improve it a bit for when I hit the country hills.
I've rung around and got various options from centres quoting up to $10k for all sorts of work. It don't think i need to get that carried away.
Any one out there got a suggestion or two?
Cheers

how do you want to improve it?
power wise?
Handling wise?

[toost11]

Handling is fine
Power really. Cruises along very nicely on the flat at 90km with all that weight but slows right down on the hills.

Get a trans cooler if it’s an auto

Maintenance wise:

Change the diff fluid to a quality recommended synthetic.
Use a decent XW40 or Xw50 oil as your oil temp will be much hotter and change it regularly.

supercharger

You're in the same boat as me, except my One Tonner X6 is slightly lighter than the Crewman X6, and we tow about 2t with the rally car and trailer PLUS half a tonne in the tray. I wouldn't say it struggles, in fact quite the opposite, when we went to Melbourne this year for a rally we sat on WELL (and I mean WELL!) above 90km/hr. Is yours a VZ1 with the 4spd or VZ2 with the 5spd? I find in our 4spd (X6 OT didn't come in VZ2) that 90km/hr isn't high enough in 4th gear to be useable, so we tend to sit well above that to give the engine a change.

As stupid as it sounds (and less stupid now that it's out of warranty) I've very much considered a supercharger, and it would probably both improve towing power, and improve towing fuel consumption. But if you've got the 5spd be weary...

id go for a vcm suite tune, other than that for more power f.i is the way to go

Can't believe no one has said "V8" yet?

[TVR-190]

ya go a v8 turbo diesel, thatll tow the factory your car was built in.

diff ratio change will help..

REALLY hard to do in the AWD's. V8 would be a waste of money when a supercharger for similar, if not less dollars will delivery the same results without re-wiring the entire car.

If going V8 I'd just get a whole new car.

The time/effort involved in the transplant, lower resale value (compared to factory V8) and the general low prices of gas guzzlers at the moment doesn't make an engine swap the most practical option.
