Dude, go for a drive in an Sti with 200kws at the hubs and then tell me how much more grunt you need, there ain't too many things that will beat this combo and its not a huge outlay of dough to get there (3K max) and a pretty reliable setup. If its not enough, be prepared for big dollars let alone the grief with these sorts of things, just gotta ask a couple of guys on here with big horsepower how many Panadol Forte they have had getting things right and how their bank account is fairing...
