who did it?? 2000 is alot of dosh!
if its high flowed mate, i honestly think you shouldn't upgrade it until you've used it..
bigger isn't always better
i know the biggest comp wheel u could fit would be around the size of a 20g turbo
and u could easily make 200kw's on that turbo
if its an 060 exhaust housing, and u want more flow, just get an 070 exhaust housing and bolt that up for more top end
not sure how far they are, ill probably drop in today
