I'm not going to try and influence you as you know which way I have gone. But what are your goals for the car? Is it going to be a daily driver, race car, etc, etc and go from there.
I went the way I did for a number of reasons. I wasn't after a big horsepower increase. I just wanted something to give me that extra poke when out on cruises, or the freeway where you need to overtake. The car was already built and painted from a number of years ago so I didn't want to go about cutting it up to fit intercoolers or changing the firewall, etc. Most importantly I had all the correct gear sitting in the shed not being used (no re-sale value for a suck through setup) and I wanted to build the car so as to keep it in the era.
Personally I wouldn't try to go blow through as work is required on the carbs to handle boost plus fuel pressure regulators and so on. I have seen some that have intercoolers and ECU's to run them. You may as well go the EFI route. As suggested to much hassle, it makes much more sense now days to go with something more modern like Zetec or Duratec.
The one thing for sure though is once you have turboed it and DRIVEN it, you will never want to go back to carbs.
