have you looked into the engine mounts and the fact ul need to cut the front driverside top of the front panel to allow room for the head of the wider 16v'er. also how much have you looked into the what ecu ur going to use and the wiring?
iv looked into it alot as i want to go for a st150 or 170 lump and turbo or supercharge it. maybe we could both help each other out with info. mine is a way off yet as im stil deciding but should be a good project.
what brakes are you using?
