im getting an rst next in the very very near futureand im after a little advice as this will be my first!

first off, my first job is, im after upgrading the cooling from the standard set up fairly cheaply, is there any way to do thisatall? ive seen a cossie cooler for sale thats modded to fit rstsand ive also seen something about using a cossie thermostat? but whats best, getting a bigger rad or bigger intercooler? im a bit unsure as to whatto do? can anyone advise?

secondly, im after a dumpvalve set up, i know that they are supposed to be not that good on rsts but i want one. ive seen all these different applications to put it in different places, which is the best place to put it? i.e chearge carrier over the crocker or boost hose (i think thats where it is?) whats the reasoning behind these different places?

and finnaly for now!!!!! what are they like on fuel, as im after using mine everyday and i can sometimes do a fair bit of distance to get to different places of work only doing 60 a day atthe mo so not too bad!

cheers, any help woulkd be appreciated, cheers! phil
