Use standard Monster Gear ratios,18 pin/ 46 spur,worked out just fine on my 4WD Beetle,with monster wheels on,as already said with stock gearing will be slow on take off.

I had same thing on a Punisher,so made a gasket for it,worked for a fair while,Some Orings are ok with petrol, so should work well,and even if they don't last,spose cheap to have a few spare.
