My thoughts if you want lots more power l would sell it and get something like eg Toyota Supra Twin turbo etc. The only mod l would do is an CAI, or maybe an exhaust thats all. People do not realise that when you install a supercharger,turbo etc other components like the driveline,diff give. So then you need to strengthen the driveline,diff, improve the brakes,pc and the list goes on and on. If you have heaps of $$ slap on a turbo but the costs start adding up. Just my 2 bobs Sedat
