Boost is a measure of restriction based on your flow mods...honestly as nice as it'd be to have a A2A IC...look at how large the cores are and how they route on the Aussie cars...you'd have IC pipe running out the passenger side fender. It's been tired...which is why the W2A IC's are tried and true...and you'd save money in the long run because as much as I'd give you props to make it work...the money it'd cost to re-create them and sell them wouldn't really be cost effective IMO.
This is an example of an Aussie core...
See what I mean?
