a really good item to use for turbo charging is the metal bonnet from a tempo, topaz or taurus...i got mine from a tourus for a ram air setup...its solid metal and is very strong and is quite easy to plumb line to from the turbo...although usually the hole needs to be enlarged to fit the carb unless u have a Carter RBS 1bbl carb which would not be good enough i dont think for turbocharging anyways. and its about as tall as the triangle eldebrock filter...maybe even a bit lower.
