Carb Question

How well do you guys think a Holley 5200 would work for a turbo application? And if that carb will do the trick, would it be possible to mount the carb with an adapter or is direct milling a necessity? I'd prefer not to mill if I don't have to, and I'm considering the adapter and carb from stovebolt. Thoughts?
 
So I take it no one has ever actually tried this combo? :( Uncharted waters kinda scare me. How about the adapter? Has anyone ever used one of those in a turbo setup or is it all about the direct mill? I have gotten so many backwards confusing answers I have no idea what to do when it comes to carbs.
 
Well, why not leave it be for now, and invest in an aftermarket ECU?
 
But thats a whole other can of worms. I mean as much as I'd LOVE to have efi, on a scale of 1-10 isn't it like a ten in difficulty? And how much would you say it costs to set up a system like that?
 
Are you comfortable with computers and electronics?

Have you ever worked with electronic components? Built any sort of electronics project?

If so, EFI is like a 3.

Personally, I find EFI much more straightforward than carburetors.
 
I am very comfortable with computers, probably more so than cars even. But cost is a major concern. Any place you guys would suggest that I can read up on the basics of it? Any pages with step by step photo illustrations? And then is is just a matter of reprogramming the ecu for a turbo setup?

Now I'm incredibly intrigued. Has anyone done this on a vintage mustang before? And in terms of actually fitting it to the car, how did it go?
 
Think of it a bit like building a house. You're worrying about the door locks, without even having stood the frame yet.

With an ECU you can just leave out (not utilise) the things you aren't ready for yet.

If you put it on the car right now, all it would be doing is driving the ignition. That could give you coil-on-plug multiple sparking - already ahead of an MSD. Next you would fit an exhaust bung, and be able to datalog the O2 readings - helping to tune any carb... Then later you could go with either TBI or multiple injectors, and turn on the injector driving function. After that, with a turbo - the framework is already in place, so you'd be able to re-work all the parameters to suit forced induction.

Ironic, because it appears the rest of my hair has been traveling downwards for the last few years.
 
Sorry I get excited and then don't search before asking questions. I read and read and then get more confused. Plus I always have trouble with the search feature. Makes me seem less computer literate huh? Let me do some reading and get back to you guys. I appreciate the help but sometimes I get so many ideas at one time its hard to keep them straight.
 
The only thing holding me back from efi on a forced induction is the cost of hardware.

Individual throttle bodies=ungodly $$
TBI=Any OEM unit from an older vehicle won't flow enough, and a performance TBI=ungodly $$

Moe's seems to work pretty well...The restriction in pretty much any TB setup is the injectors. There aren't the airflow compromises (venturi vs. total flow) like required with carb design. Aux injectors would solve that pretty easily and quickly, maybe plumbed into the bonnet like on the HRM article.

Ok now that i've done some reading I have a few questions. I would like to do the efi swap. :D And I want to turbo it :D so my questions come from a combo of the two. In terms of fuel management:

Will the tempo throttle body be able to supply the fuel demands of a turbo? If not, what would be an alternative to this setup?

Linc's200 and does10s both describe those fuel demands and suggest a high pressure system. It would seem like the mallory 4309 (boost referenced) and a high volume pump is the way to go for a turbo, but something smaller is necessary for the efi conversion. Which is the way to go?

Hopefully these are intelligent questions and not just an oversight on my part. :lol:
 
That is....AWESOME O_O heh

So I imagine one has to time the injector squirt a few milliseconds befor eit would reach the intake valve(s)?

Will the tempo throttle body be able to supply the fuel demands of a turbo? If not, what would be an alternative to this setup?

No, that Tempo EFI will not flow enough. The other options:
-Individual throttle bodies, with individual injectors.
-They make aftermarket TBI's for engines such as a Chevy 350. I imagine that would work, but they are pricey.
-See a2 posts up. Seems like the most cost effective way to go.
