Drawthrough or Blowthrough Turbo setup?

I got a T3 turbo in the otherday [img]images/graemlins/grin.gif[/img]. Now I was pretty set on making it a drawthrough set up with a weber, but most of the guy's over on the team swift site seem to think I should go with a blowthrough.

First off I dont want to convert to EFI. It's a brand new Weber and I'm not trying to go all crazy with this turbo and redoing my hole setup for MAX HP. I got a good deal on it and figured I could make a log type manifold and an adapter for the carb to bolt on to the turbo intake for practicly nothing. Then I was going to plumb the turbo over the valve cover to the intake manifold and buy a MSD boost timing retard unit and connect the exaust to my existing 2.5 pipe out the back.

Now that Iv been over on the team swift site Im considering putting the carb in a box with a solid float and using a Lokar throttle cable and bolt the gas line throught the box. That seem's like alot more work and I dont see how the carbs going to work right seeing how its going to be pressurized. [img]images/graemlins/thud.gif[/img]

Iv been reading Hugh MacInnes "Turbochargers" book. It has a great deal of carb info and the drawthrough method seems like a slightly less effective but much simpler way of going about this.

Any Ideas ??? Here's a pic of the only drawthrough geo 3 cyl engine I could find. I'm thinking of keeping the turbo and carb over on the exaust side.

Keep in mind my intention isn't to have a fire breathing 1.6 8v like the guys over on team swift.
