thanks a lot guys, like i said earlier im not thinking of going crazy about the power gains. maybe an extra 20-40kw from what it is now? on paper apparently the b18b2 has 107kw but i know its not going to be 107kw for sure. yeah soo stock internals would be fine depending how much power gain im looking for? is that right? i found a few turbo kits on ebay like godspeed and turbonetics i think. anyone has experience with them brands?
