I've been told that you can't realy bolt on the turbo guts of the turbo engine of a C900 on to another N/A c900 engine. I came across THIS site wich gives details of how to turn you non turbo classic 900 into a turbo. I imagine because it's a LPT that it can be done but if it was a HOT it would blow the engine.... Any suggestions or thoughts on this??

 

i would imagine that the only difference in the 2, other than some improved head flow, would be the compression....it the compression wasnt MUCH higher in the NA head, a thicker head gasket could almost make the difference...
