    I can't fully explain how to do it in one post. It's not that hard; if anything, it's easier than fuel injection. A draw through carb setup would need no modifications to the fuel system or carburetor at all. The downside is that you can't have an intercooler, and the compressor outlet must face down. You also must have a turbo with a special compressor seal to prevent oil from being sucked through when you close the throttle. A blow through needs a few small things done to the carb (no special carb needed), a high pressure fuel pump in addition to the mechanical pump, an FMU, a BOV, and you can use an intercooler. A blow through is a much better in just about every way. However, I'd limit my boost pressures to no more than 8 PSI....

    Ahhh... G10 or G13...? I can't recall which. Stout engines. With proper tuning, they can handle quite a bit of boost. When you said truck, I thought Chevy or Ford...

    Where do you live? This kind of determines if a draw through setup is even possible for you.

    a blow through sys. will be much more efeicent but remember you have to keep your fuel press. 6to 10lbs. above your boost press. thats the trick. I twin turboed a chev 350 many years ago it made alot of hp @ tq was very fast at the track but inconsistant.Good luck be creative

    You wont be able to start your car in a draw through system if it's excessivly cold out. The cold turbo will make your cold-start mixture fall out of suspension.
