i agree with joe.. having 2.5ltrs only makes the power come on earlier... the 20g would have a limit of around 220kw atw or similar power output to joes.

The green however which i had on my car made 233kw atw whilst it made 240kw atw on todes car.. This turbo has a bigger exhaust side asfaik. So i dont think ull be beating that..
