After looking for a while, I still haven't found anything, the question is,
Does the RTA have any regulations reguarding engine mods such as cam duration, valve lift etc.
After looking at all the 4AGEs on the forums which aftermarket cams etc. Most seemed to be around 270ish duration with about 8mm lift, though when I get round to completing my car, I'm looking at running 280 duration with 10.3 lift (with aftermarket springs, shims etc. of course), but because this is so much more than the average here, I'm guessing theres either a regulation on it, or that much lift makes the car horrible to drive on street lol.
I know there's regulations on how much extra displacement you can add, but can't find anything on the above...:S
