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.
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.
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).

Nope, it's a sucker. Used a goofey carb that was used on the 6 cylinder Corvette.

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.
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 ....

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.
