Willies consumption does seem extreme but I have seen a few of the hiluxes that are extremely thirsty no matter what you do. sOme others do 8 to the litre without ever touching them. My van was doing 8 plus when it was standard but after the lift and the big tyres i was down to 4 on a good day. The conversion has worked wonders for my setup and on a trip to lesotho just after the change i was getting 10 plus on the open road. I road backup for some quadbike tour and they payed for the fuel so everyone was extremely impressed. I carried 400 litres of fuel, 100 litres of water in jerry cans camping equipment with 4 adults in the van and the trip through lesotho( permanent 4x4 and most of the time in low range) I averaged 6.5.
The power difference is unbelievable and offroading has become an absolute pleasure. most of you have probably wanted to get out of your van on a steep climb and kick the thing because it has a flat spot just where you need that little extra in 2nd, that is gone and climbing hills is a pleasure now. Like I said before, a mate of mine in jbay did the conversion and he has experienced a massive power increase but very little difference in his consumption( he has '92 d/c) he says he is getting the same km per tank but he also says he finds himself riding much faster so its difficult to say what will happen once you have done the conversion. for me it is the best thing I have ever done and will never go standard again. Those 33" coopers dont work well with the standard carb and you probably use a litre everytime you pull away, absolutely no power.
another friend has a 2.4 '89 model with(believe it or not) a million km on and he again swears by the standard carb with all the vaccum pipes in their exact places and he gets 8.5 in town so he wont change at all. the gamble is yours. it cost me 250 for the carb, 40 for the rubber spacer, 12 for a piece of alluminium and 0 for machining so it was worth a try and it worked for me.
just remeber to make sure that your plugs are set at .8, points .4 and very important, when using lrp fuel, your timing must be set at 8 btdc on the dot (vacuum pipe off) and not 15 deg, like some people set them( this info was given to me by Algoa toyota's oldest and wisest mechanic) and this also make a huge difference.
freeflyd, it really is that simple and dirt cheep. those webers are expensive and damn thirsty
