wish i still had mine... dodge your looking at the cam base circle wrong, it doesnt take strength away it is still just as thick-or thicker than the main shaft. If i can help with the turbo stuff let me know, if your handy with a welder it's pretty easy to make a adapter that bolts up to the stock manifold and it's so worth it.
