Are you talking about the MSD with boost retard? We did that on my son's supercharged Studebaker. A good unit. I have a new/rebuilt HEI that I planed to use. I measured the output of the turbo today. It is 2". The stock intake manifold carb port is 1 7/8'. If I cut the 1/8' to the out board side the inner stud would aline the unit perfectly. Then by milling the surface the remaining 2 holes would easily fit on the mounting surface using the stock Pontiac gasket. The three bolt 292 exhaust manifold flange and the turbo in flange apear to be the same. A simple "U" bend could connect them, There's a start. Thanks , I don't mean to ramble. As far as spendy goes, the piles are already here. The rest is like Apollo 13, make this fit that using this. Hot rodders in space!
