It's hard to do a turbo through a carb. You can have the turbo blow through the carb, but it's really finnicky.

 

But if you're planning on putting a carb on and getting rid of the turbo, you run into compression issues....or lack thereof. Turbo engines have lower compression than carb's.

Also the Turbo manifold is 4 ports, totally different from the SPFI and carbed manifolds. You would need different head and pistons to make it work, or some kind of adaptor to mount a carb to the spider manifold and plug the injector ports, but you would still need higher compression pistons to make it run right. Blow through carbs are expensive, so if you plan on staying turbo, not the way to go.

It can be done. You would modify throttle body to mount a carb (weber, etc), and then put the whole carb inside a pressure vessel. You then pressurize the whole thing with the turbo. You have to deal with fuel pressure issues - for every pound of boost you need another pound of fuel pressure to correctly operate the float bowl, and getting it all sealed up and running correctly is a real mess.

 

Anyway - yes, turbocharged carbs have been done. It's nothing new, but it's very ugly.

I've always liked the idea of running turbo heads on an NA block with a Carb. No turbo, but Dual port intake and 9.5:1 comprssion with a big Webber or even a holley would be ba-dass

 

I think Triker bob has this setup on his trike.

It could also be done by having the carb mounted on the intake side of the carb so it pulls through the carb. BIG jets are needed and it's basically tuned for wide open and full boost so at lower rpm it may not run correctly on the street.
