Without wanting to cause offense or come across as a cunt, aren't you at all concerned this isn't going to offer much in the way of drivability? I'm sure it will be ridiculous once rolling and going in a straight line, but if you try and attack some back roads or a track it'll be horrible. Maybe I'm missing the point, but if it were me, I'd be looking for something smaller which might sacrifice top end power, with more low to mid range torque. I had a GT28r turbo fitted to my FD RX7 and it was mega, but a larger turbo on a smaller engine, doesn't compute. Best of luck with it anyway.
