Im sure 151kw would be more than enough for me too. I also find myself looking for another gear. At 110kph the 1HZ seems as if it could handle a 5th with a higher ratio or another gear.
However I think the 1HZs lack of noise is misleading and if there was another gear it would bog down on a slight incline.
I did 730klms in my HZJ75 in 7 hrs a few weeks ago on quiet country back roads.
I sat on 110-120kph and had 3 breaks for fuel and food.
It used about 13-14 ltr per 100klm with about 500kg in the back and my canvas canopy working like an airbrake.
It would have been hard to convince me then it needed more power . Its over taking at speed where the 1HZ falls down but I only had to overtake 3-4 times that day
Geez I bet you had a sore arse!! Thats a fair haul. Still you guys are used to those big distances. Can't do it here the roads are not good enough. Have done a few 450 - 500ks in a day, but it was in a work truck ( NIssan Navara 4WD) and there was no way I could have averaged what you did. Does the 95 model there still have leaf springs on the front or were you guys coils by then, and with the extra bit in the cab? At least you could stretch out a bit. I found the 91 model I had a wee bit constricted for longer trips, but still OK. I could drive for 3.5 hours not stop, that was about 320klms. We did not get coils on the front till the 96 model.
Hopefully if your dealers are getting them in a might be only a couple of weeks till we see them here. Would appreciate a bit of info if you are looking Rosco. Is the change to hi 2 to hi 4 still the same? is the transfer lever the same? I am getting a VJTN model, thats the one with the Mags, and carpet instead of vinyl, comes with aircon, bucket seats, and diff locks. We get them here as a cab and chassis, and I am getting my own deck made. The more basic model still has split rims, vinyl instead of carpet ( I might regret not having vinyl) not sure if it gets aircon, and the same old seat. We had the choice with the 79, with those options as well or the non turbo 1HZ as a basic truck. You could get a "high country kit" which gave a snorkel, diff locks, and disc brakes all round. With the turboed 79 you get the snorkel and discs as standard, and the diff locks were an extra. with the new model the "GLX" and the standard model get the same V8 and snorkel. The only option will be if you want diff locks or not. Will have to wait and see.
