AWD belta

[supmet]

So after seeing an AWD belta in this thread, I decided, I really want an AWD yaris. I've searched all around the forum and the internet, and not knowing japanese is kind of limiting my ability to research...

The only AWD yarii that I have seen, have been RHD, and come with a 1.3 liter engine putting out a measly 80-90 hp. Is the AWD sold anywhere that is LHD? Do you think the drivetrain can handle more? Like a 2zz or a 4age? Also, does the AWD assembly take up more room in the engine bay, making swaps even harder? Would it be easier/cheaper to just custom make the yaris into an AWD rather than worry about importing everything and hope it fits?

If all of those questions are stupid, point me in the easiest direction of making an AWD 'wrx killer' yaris
