When I was younger...I had a 01 Celica GT..not much you can do to that car! I decided I wanted to make a custom turbo kit for it...I was a broke college student so I knew I had to do some dealing to get the parts I wanted...I got in contact with a shop that was already making kits for the MRS which has the same motor as the GT...through some negotiations between them and my local shop I had alot of free or at cost parts in return for a jig that we produced for the FMIC piping. I pieced together a kit and got 250 out of a motor that makes about 160 stock. You can make custom kits look good too!
within a year I blew a softball size hole in the block and bent the #3 rod in a Z shape...lol
