yes the air filters or on the engine. i hadn't thought of that one. but they are UNIFILTER ones, designed for the carbs like mine, they shouldn't restrict it.
well i bought my ute without reg so it means i have to get it registered, and they will want to know all about it, ill only tell them if they ask about it...
i do know an engineer. well, a guy who did the course, now he can certify truck extenions/ute extension and make trailers and all that so getting the tray in my ute engineer will be ok (i put new sheet in where the old rusty one was).
As far as vicroads:
Engine still is A series, that all vicroads need to know (technically i think A15 is within capacity upgrades anyway)
5speed: well international ones come with 5spds, they dont need to know mines from a toyota...
exhaust was made by Cameron Krahe engineering, that sounds half legit. i know a farmer who makes most of his equipment, like augers and fieldbins and he says something about Ravana engineering, coz his farms name is ravana. lol
anyway, updating the ute.
it is at a good mechanic now. i am pretty sure i could fix the problem, but ive got it at the mechs so he can run an eye over it, plus ive got a few things that need doing that i dont have the right tools for...
im almost certain it is just old plugs.
