Hey, so my mate is running a turbo on his bugeye wrx. He has a 2.5l wrx engine in it and is also running a front mount intercooler and fuel pump. The car drives really good! And he said it made 270hp. I was wondering if I put the gtps02 on my 2.0l wrx would it work well or would there be alot more lag? Would the gtps01 be better? I was also surprised that he didn't change his injectors. Does anyone know how much power the stock injectors can run? And how much power the stock fuel pump can handle? Keen to chuck a bigger turbo on the wrx but on a budget, so was wondering if the upgraded injectors and fuel pump are needed? Would be happy with around 190kw

Any info would be great!
