Hi All,
Have just come back from 10,000 + km of touring Qld & NT with a camper trailer. Can't wait to go again. While away we had a bit of trouble with exhaust getting squashed, cracked etc, which at times caused loss of power (not that it had that much to start with) Had it replaced, re welded, repaired at different stages during the trip. When towing it went from about 12L per100km (best) to 19L per 100km (worst - when having exhaust trouble). Generally quite good considering the engine size and weight carried.
Had the exhaust replaced today with extractors and new pipes and next on the list is a snorkle to get some cool fresh air in.
I'm not after axle snapping, neck jerking power (LOL) but has anyone got any suggestions? as to any other modifications/ tips that may help get a little bit more towing power? Even though the engine still seems solid I don't want to go turbo as I think that may be too much for the old girl (and me).
Cheers
Kev

I had a turbo on that model and had no problems. Had done around 220,000KM.Usually got around 11L per 100, but could get 10 if driving very gently. Towing a 1000 KG trailer went up to 15L.

I know you said you didn't want to get a turbo but it's really the only answer!

and its a pity you wasted your money on extractors as that is 1/4 of the turbo price. You dont have to run the turbo at 15 psi boost, I run
mine at 7 and get about 100 extra ks per 60 liter
tank around town, got 234000 ks on it. More power on your engine puts extra strain no matter how you get it.

Thanks fisho, haven't totally ruled out a turbo as yet. I spoke to a guy at Denco and he advised against it because of 245,000 on the clock. He said he would send me the kit to fit myself, but they wouldn't fit it because couldn't guarantee the engine wouldn't go fizz very soon after fitting. If I had the engine rebuilt at the same time it wouldn't be a problem.
Cheers

Gday
This wont get you any more power (maybe a poofteenth) but it may save you money on an engine rebuild, the engine sump in the Hilux does not have a very big oil capacity and in hot weather and towing a trailer the oil temp will get extremely hot, I would suggest installing an engine oil bypass filter to help minimize oil oxidization by removing soot contamination and increasing oil capacity.
Filter Technology sell them, I would suggest the FM02 because of its larger oil capacity.
Some years ago I had a diesel van and I installed a few gauges one being an oil temp gauge, the gauge barely moved around town in an ambient of 35-40 degrees but once on the open road fully laden the temp rose to over 150deg (125-135 would be ideal) 150deg will kill an engine, the only way to lower the temp was to travel at 80kmh, what I did after the trip was install a bypass filter up front on the roobar (good air flow), after that the oil ran at 125deg C in an ambient of 45 deg it has since been on three of my later cars. Money
well spent, I have also installed the same filter as a fuel filter, but that’s another story.

Thanks Stew, sounds good advice.
I will look into that, as no matter which way I end up going (turbo or non-turbo) I do need to keep the oil temp down and the oil clean.
Thanks Again

The ol' exuast squash problem... Must have grinded
mine back about half a dozen times before I replaced it, pain in
the neck eh!!
I agree, turbo's the only way to really make her go... High k's could be a problem, but hey put it on anyway, if it's gonna go it's gonna go anyway, the turbo will still be fine, then rebuild it.

Thats what Im doing with our 4 Runner,bolting the turbo on(
well its on ,just waiting for the injectors to come back and then a tune up),If it blows,I'll slot a new engine in, $5000 with 12 months factory warranty.
Our old girl has 190000kms on the clock but have done too much to it to sell it without loosing a heap.
