The .81 is small but it works for your setup better than your 67mm. If you had a 72mm with a .81ar, i think you would be happy. If you watch over at TheTurboForums you will find new MP 's cheap from the vendors. Start a thread over there and ask about your combo, see what they tell you.

Build what you want, i just gave my .02 from the start and i hate to see people go through what i went through, shits not cheap. I truly do not care what your car runs or what it makes for power. Stop bringing my name up when someone tells you something you don't like about turbos here. I had a fast car with a turbo and i'm building a faster twin turbo car now, that's all.
