Has Anyone Ever Seen A Carbuereted Tii?
 
I am wondering because I own one and its a pain in my ass. I am looking for any info out there on these setups. I have been told that If set up right it should be faster than EFI. Its easier to work on but harder to tune.
Car and Mods:
88 Black TurboII, Streetport 13b, 3mm apex seals, Turbonetics hybrid, Trust FMIC, Greddy type-s bov, stage clutchmaster clutch, C's short throw, and of course the blow through carb set up.

Why would it be faster? Why would it be easier to work on?

That's bs.

Get a haltech, dyno time, and it will be faster and easier to work on.

in theory it would be easier to work on...also you can tune carbs manually w/out a computer. The reason it would be faster is both that a carb mixes air and fuel together better and that it would eliminate the afm. But all in all I would (and did) go with efi. My car used to be carbed too and I hated it as well. Corkey Bell helped me out a little with my setup (it was a cartech).

I'll give you that one, but you still need a dyno, and more parts to tune. As well, to keep it running perfectly, you have to retune it for changes in altitude and ambient temperature.

Fallacy.

and that it would eliminate the afm.
Most aftermarket ECU's do this as well.

It sounds like a good setup other than the carb. Whoever told you that the carb was better than EFI was either trying to sell you the kit, or stuck back in the 70's. It's going to be a pain to get the fuel pressure rate matched to your boost level so your carb bowls stay filled, and you will go through a lot of jets and emulsion tube changes, but your setup should still work well if you spend enough time on it. There must be a turbo/carb guru somewhere near you who can help you out. Maybe Corky Bell can help you, LOL.

I disagree. With EFI, you can tune the engine from the cockpit. Having to shut down, get out of the car, and open the hood to make "guessing" adjustments with the screwdriver is ghetto by today's standards. IMO there is a difference between "easier" and "less advanced".

You have it backwards; EFI mixes the air/fuel mixture better. An aftermarket EMS will also eliminate the AFM. Additionally, EFI does not require a low-pressure venturi, and it gives instant acceleration off idle, unlike a carb which tends to stall while the vacuum builds. Really, the only advantage of a carb is the price.

I curse the carb on my 1Gen on a regular basis. Fortunately, I also have a carb guru to tune my car, or I would have ripped that POS off the car, thrown on a Wolf3D, and changed the car to E Production class specs. :D

This is a key idea that is lost on many people in cars and computers...

If something is advertised as 'easy to use' I read that as overly simple and weak...
