I'm looking for cars that cam factory with a turbo and a carb. I am wanting to do a blow through set up on my car and I'd like a carb that is already set up for it. My stock carb is a holley 5200 so one that will swap over easy would be nice. I have a 1.6L and I'm looking for about 150hp or 7lbs,which ever comes first.
Any other good info on this kind of setup would also be appreciated.
1979 Ford Mustang/Merucury Capri. 1983 Buick Regal, Riviera.
I've seen a carbed turbo V6 Riviera from the early 80's, but never a 4cyl?
No I was just using turbo carbs in general. Finding an OE blow through is going to be hard enough as most of the OE turbo carbs are suckers.
Maserati biturbo is a blowthrough, along with that weird 50s kaiser thing with a flathead 6. The turbo regals used a normal 800 cfm q-jet, and it was a drawthrough setup.
Was the Colt Turbo a blow through? What about the first generation 2.2 Dodge Turbos?
Corvair turbo was a blow-through, I believe.
Early SVO fox body Mustangs were turbo 4's, not sure if they were blow through or not.
The Dodges were fuel injected as I recall.
GT Turbo Mustang's were draw-through in the early years. The 3 years of SVO were EFI, as were all the later GT Turbo's and the TBird Turbo's, etc.
Factory blow-through carbs are nearly non-existent. Your best bet is to either have yours rebuilt to handle it, buy an aftermarket (4Bbl only unfortunately), or go EFI (MegaSquirt).
Or build an isolation bonnet. Pressurize the whole carburetor.
^ That would also work.
What setup was the first TTA?
EFI for the Buick V6 based ones. I'm pretty sure the craptastic 301 V8 was a draw-through.

Nope, it's a sucker. Used a goofey carb that was used on the 6 cylinder Corvette.
Early turbo Starquests were carbureted.
I assume you mean the Mitsubishi Starion/Dodge Conquest?
What about the early Escort EXP Turbo's?

Starquest is a common contraction for Starion/Conquest
Just FYI, you can repurpose a cheap aluminum pressure cooker into a pretty nice Grassroots pressurization bonnet, they are already built for sealing and holding 1 Bar of pressure at high temp, and come in different sizes. Mount the carb through the lid; use some flat plates and a bunch of JB Weld to get the inner and outer mounting surfaces level and flat on a curved lid, then use a holesaw for the center hole(s). Weld a pipe onto the 'pot' section in a convenient place for the pressurized air to enter. The rotate and lock mechanism allows you to remove the pot for easy access to the carb.

Seems like a lot more work than just mounting the carb through the bottom of the pot?
Not a half-bad scheme, though, and certainly priced right.
You'd be cookin' with that setup. www.instantrimshot.com
Couple running Starions on Atlanta Craigslist yesterday...

If you mount the carb in the bottom of the pot, it's a real bitch to get to. On the lid, it's right out there ....

^^^ good point!
20+ Years ago I looked into turboing a car using a blow through carb set up. I even have some info on how to modify any carb for blow through. Better to modify the carb then to enclose it. Remember you have to run a number of lines, hoses, tubes, and a throttle cable throught the bonnet. All sources of air leaks.
At the time these was no grassroots sources for converting a car to fuel injection that never came from the factory with it. Now with Mega Squit and what all these is no reason at all to use a carb, none!
The only common car to use carbs & a turbo was the early FOX chassis cars, Mustang & Fairmont came with 2.3L turbos with suck through carbs.
I love turbos, I love carbs. Somebody translate the jargon in this damn thread for somebody like me who's not accustomed to both on the same motor.
