That's even better. Have to let me know how it works out for ya!Originally posted by Dom88festy View PostLeave a comment:

I've actually contemplated doing this same thing. But I'm thinking the stock carb is not a good choice. Plus you would need bigger jets for more fuel, and it would have to be well timed. Because as you get more air flow, your gonna want more fuel, but you don't want to make it get to much fuel that it loads up at idle. It would be optimal to have the turbo kick on when your second barrel opens up (with the proper sized jetting which you would be drilling on a stock carb). I would get an aftermarket setup with some more adjustability. Hope you get the kinks worked out! I would like to see someone try this so I can some pointers before doing mine. I have also contemplated making jet adapters for mikuni jets. They would be easy to make and are readily available. Good luck!Leave a comment:

Okay thanks man! And thanks for all the help everyone!! My list isn't that long for everything i need lol. Just an aspire exhaust manifold, oil lines, some piping made and a new turbo I think!Leave a comment:

I can get a pic when I get back from vacation, but I asked what was done to the carb a while back, as I got it with the (junk) car it was used on at one point.Originally posted by Dom88festy View Post
"It's been modified for blow through turbo. Brass foam filled float .135 needle & seat, .035 Accelerator pump nozzle, 50 cc accelerator pump, 10% accelerator pump cam, milled choke horn, power valve block off, high & low speed air bleeds, threaded & adjustable air bleed jets installed, replaced throttle plates with drilled idle bleed holes with solid throttle plates, installed down leg boosters, polished & deburred venturi bores, 362 cfm @ 1.5" of vacuum, drilled power valve restriction in metering plate."
He said the work ran the guy $500-600, not sure if that included the original carb or not. I wouldn't need nearly that to let it go.Leave a comment:

If you've got an airbox for your carb and are planning a blowthrough setup you're ok to run a front mount since there wont be any fuel in the air coming from the turbo...sorry for rambling and being confusing
With a blow through you might be able to get away with that wrx turbo, I would personally size something smaller but I am by no means THE authority on these things... you'll probably see lots of lag if you make boost at all, but that's what makes turbos fun!Leave a comment:

The guy I bought it from acually made an air box where no air can escape I'll get a pic when I can. And I wish I could run a front mount! Lol. But I guess I'll have to find a smaller turbo

Not THAT complicated lol but there's some doin to do for sure. A blow through carb like what brad has is maybe a bit more simple, and probably a better option for performance since the carb will be less of a restriction. Main concerns there (assuming the carb is squared away which I'm sure it is) are finding a way to keep the bowl pressure about 1psi higher than your boost pressure (this will be with a fuel pressure regulator takes in boost pressure ... See eBay) then just some way to seal the boost in at the top of the carb. Then spend the rest of your time tuning the carb. There's a lot of reading elsewhere on turbo'd carb setups...just google draw through and blow through turbos...Leave a comment:

Thanks for all the help guys! It seems pretty complicated to do this lol... but bhazard can you show me what that looks Like please?Leave a comment:

I have a holley 2bbl that was modified by Matt Dickmeyer for blow thru if you're interested.Leave a comment:

I have the entire draw through setup from a 1979 mustang in my garage right now. The intake path is so ridiculously short, and is all part of the intake manifold. Common sense tells me this is to make sure the fuel doesn't have a chance to fall out of suspension, but I think sketch may be onto something since the intake would stay fairly warm as well. I vote do it! just keep the turbo as close to the intake manifold as possible (hang it over top of the transmission?). Look at Corvair or VW forums for more info...The Corvair used a draw through from the factory and drag VW and buggy guys bolt on draw through turbos all the time.
Draw through stuff is pretty simple, no carb mods are necessary...you can use any turbo...dynamic seals may or may not fail after a while there are some conflicting views on this...
Also, If you're going to do a draw through you can't use that FMIC unless you're trying to turn your car into a time bomb. First that would make your intake path WAY TOO LONG, second since the air your pumping through the intercooler will be full of fuel some (or lots) of that fuel is going to fall out of suspension in the intercooler, which means you're only one backfire away from having a really bad day.
more specifically...that wrx turbo is probably too big for this application. A draw through setup (sort of by design) will be a bit laggier than a normal setup, and assumming you have a td04 you might see boost somewhere around redline lol...so sell that...sell the rest of your parts...
Then get a cheap teeeeny tiny turbo, one of the two turbos from a twin turbo car is usually a good bet (see volvo t6 or 3000gt or newer bmws)
I would recommend a weber side draft on one of these manifolds http://carcraftstore.com/carbmanifold-dcoeanddhla.aspx
Find a decent low pressure electric fuel pump and regulator
Then if you wanna go nuts lookup DIY water injection on google and buy all of those parts, if done right this could help you from absolutely melting your little B3
With all of that together you may be able to make a little bit of power...and might not burn your car to the groundLeave a comment:

Hmm. I think the heat from the turbo and the mixing ability it has would probably help with that, but IDK.Leave a comment:
