Should be, but you'll have to find a way to get it into the doors. Might not be fun. > I´m also interested in installing a turbo.

Get a stock 900 turbo, exhaust manifold, and all the turbo plumbing. Keep boost to less than 5 psi. The stock wastegate on a turbo from a 900 is set to 5 psi, making it easy. You won't have to worry about lowering compression or dealing with APC or anything. You'll get about 10 to 20 hp out of the deal, plus a substantial torque increase. As far as I know, there is no way to "raise the head" - no one makes thicker head gaskets that I am aware of (but if you find one, lemme know!). You could have one custom made, as there are places that do that, but you'll pay a fortune. -Justin
