Ok, I've asked around once about Holly Carbs and turbo's. But now I have confirmed that the carb has came from RB, and it also includes an RB intake manifold. So I'm curious as to if the two would be compatible with the turbo, or will I still need a TII manny?

the intake manifold has nothing to do with the turbo plumbing. the holley will work fine with a turbo, you'll need a custom exhaust manifold and a carb hat, IC piping, IC, etc etc etc...

Oh, ok, so it's the exhaust manifold, not the intake... Well, what will have to be "custom" on the exhaust manifold? But thanks for clearing this up.

for 12a or 13b? search the forum for turbo setups. sometimes theres turbo exhaust manifolds in the for sale section but most are custom made.

you could just go to a machinist and have everything made, but that can get expensive. easier to have a friend with a welder and some skills, specially since you'll need all the custom piping for the I/C too.

whooaoaaaaaaaa, the RB holley will NOT be good for boost. it's wayyy off for even a good starting point. even the 4150 model double pumpers have to be put threw a process of milling, changing parts, different gaskets, blocking off passages, drilling, etc... before it will accept boost. do not boost that holley.

start off witha real holley... ohhhh i dunno 600cfm 4150 double pumper. get center hung nitrophyl floats, jet extensions, mill the choke... ahhhh ****. if your serious start a thread about the proper holley to use for boost.

no wait, go here www.turbomustangs.com/forums/

go to the carb boost section and you'll see what's involved.

I don't think you're ready for a turbo if you don't even have a clue as to mounting it. This is just my opinion, not trying to be an ******* or anything. I think you need to do a little bit of reading though before you even attempt to turbo a car. I've been reading for 6 months. Turbo's are not cheap in the least. In the end, my project will run a bill of around $4k. This does include a Haltech E6X though.

Well, that is what I am doing atm, researching:p But it sounds like I'm better off going with a different carb, maybe a Webber? Or will the Holly be the best in the long run?

they both can be a pain in the *** to tune. just read up on what people are dealing with on both. get an idea of how to get inside the carb and know what's going on when your in there. because you will be opening it up every five minutes.

yeah. a regular holley won't work right. you can get it modified to except boost. you will also need a pressure regulator that adjusts with vacuum. the easiest fix for a holley is to get a marine holley. thats what i'll do when the money is right.

Dosnt holley make a special carb that accepts boost. Like for a supercharger. I dont know much about carbs and turbos so I am just putting tha out there.

no, holley specifically does not. there are companies, tho, that do. Carb Shop, CSU, etc.. altho, if you can rebuild a holley.... you can boost prep one. it's not too hard.

I boosted a holley on a 12A. Its not a simple thing. You need a manifold referenced power valve,4 corner idle,adjustable air bleeds, custom downleg annular discharge boosters,the nitrophyl floats, jet extensions,custom bowl venting and a few other things....a carn hat as well. Even then you will get marginal streetability. I own 6 books on modifing holleys. I also spent close to 500.00 on the carb (things I couldnt do myself). If you really want to pursue this I would suggest a webber to start with. But honestly when your done for the same money you could have fuel injection. And much better streetability. With my holley boosted 12a it would drive ok and then without warning take off like a bat outta hell...I mean rip your hands off the wheel fast. This sounds kewl but without warning it wasnt. No one could drive the car but me. Even with professional help a carburated turbo will never be as good as FI. Im sure someone will argue with me on this,but I spent almost 4 yrs with this set up and really know what Im talking about. I now have the same car with a FI turbo 13B and am sooo much happier. Just my advice,good luck.

I am almost positive holley has a supercharger ready carb in their catalog, I can't recall the part number, but I'll check at work tomorrow. I know the list price is around $500.

500 bucks? hmmm, not so sure about that. if so then all the people on www.turbomustangs.com would be using it. maybe it's not BLOW THRU style... but again.. i dunno. if you find that part number let me know. i would like to check that out. even still tho, my holley cost under 100 bucks in parts. that's the carb, rebuild kit including the neccessary parts for blow thru, shipping, etc... lol!!! i'm about to see the extent of what it can handle. if you are going to pay for a blow thru carb... go to the masters... CSU... again tho... it's not neccessary
