I picked up a turbo from a Buick Gran National at a swap meet. I think they were 231 cu in. i figured this might be about right for my 261 which has a stock comp. ratio of 7.8. If I understand things right you should get your gearing set up so the turbo isn't producing much boost at normal highway speed so it doesn't kill your mpg and produce heat constantly. I figured if i ever get mine installed I would limit boost to about 7 lbs. It seems to me that port injection might be a whole bunch easier than a carb. Gael
