Looks like the old 4.2 carby is a ball tearer 16 kw/kg against 13kw/kg for the 4.8. I think you may have typed that a bit wrong or got your kg/kw around the wrong way. Next time have a little bit of patience with newbies!
i know what you're saing but when i did the same thing on (i forget which website) my hilux vs patrol i found my 1998 2.4td hilux had more kw/kg than the 4.2dt GU! The website has it wrong.
But I agree with your closing statement!
