Turbo and a carb combo...

[TheAl]

How easy is it to run a turbo with a carb. Just wondering.

Either a pull through (carb before turbo) or a push through (turbo then carb)...

[WICKED]

Yes its possible, but not nearly as efficient as EFI.

yep what wicked said

[TheAl]

More for sake of keeping an older car with the technology available when it rolled off the production line. Computers weren't always around...

So, do you know anything about them???

[WICKED]

well that doesn't make sense at all. If you want to keep a car as you woudl off the production line, why throw a turbo on it? It woudl be better all around to put a stocker kit for a stock appearing engine and do some major head work etc..

Blow thru and push thru turbos are a bitch to tune. The carb setups are complex and hard to be consistant.

Go to Yahoo groups.com and look for the blowthru list(I think that is what it is called). It was started by Bryan Sharer who just had his 9 sec carbed turbo small block fairmont featured in MM&FF. I know several of the regulars there from other lists and they are very knowledgable good guys. They will definately be able to answer all of your questions.

I was looking around on yahoo and I found lots of parts for VW's. Then again, that is where I originally got the idea from; the cover on a VW magazine.

the words "blow" and "through" yeilded the best search

I'm looking for something old to play with (I'm talkin about a car... dont get any ideas). If not a turbo n' carb; ther is always the roots-blower-sticking-through-the-hood option.

I'm mainly out for ideas right now

[WICKED]

I always toyed around with the idea of building a 1979-1980 Mustang with a built 2.3 turbo. I have a magazine article here at home that has a very clean mustang that runs low 10's with the same setup that I described, runnign a C4 trans and 4.56 gears. The motor itself is a "stroked' 2.3 (oxi-moron) with many custom fabricated parts running 26 psi on race gas. He had about $10,000 into the car. I was just thinking of how different it woudl be.

I would still love to still throw a turbo on the bird, but funds limit my fun for right now, but hey ya never know, maybe i'll show up at RSD in mid summer with a turbo sitting under the hood.

[WICKED]

I think in a firechicken, twin turbos woudl be easier to plumb.

we'll have to see how ambitious i get.

Its really simple acually. The Dodge turbo's found on 2.2's are the perfect size and flow just right if you use two of them according to my calculations. In addition, you can find these in a scrap yard for reasonable. Buy a blow off valveand take it over to Harold's to have him fit everything and plumb it. Then at that point you woudl need a custom burned EPROM ( which my good friend Joel does on the side for cheap and is very good at it or have on of the guys on thirdgen.com do it ) . That would be an easy mild 150 hp on top of what you have with the right tuning.

Early eagle talon Blow off valves will hold 20psi when modified and can also be found in junkyards, so you can get off cheap there also. I personally would look for 60 trim turbos from some merkurs and I beilive some saabs. Mopar turbos can be used but will require more plumbing ( they have oil and water and is a better setup for longivity) vs. just an oil feed and return.

[jdsgallops]

If your looking for an old car with a turbo/carb from the factory to build look no further than an early 80's regal. The regals could be had with the 3.8 turbo option before the GN came out. Would be a very easy car to modify and should have reasonably priced parts. If I remember correctly they are a draw through system as the one guy I knew that had one liked to dump ATF in the carb to clean it out and cause a big smoke show.

Then there was the worst turbo application ever. The 301 turbo firebirds, you could hear then pinging a mile away. Most junkyard turbo setups I've seen are of the blow through variety with a boost referenced fuel pressure regulator and a boost prepped carb. They seem to work, but EFI is the only way to go with boost. Otherwise you end up leaving some of the performance on the table with a rich/safe mixture.

the yahoo group is JYtubo(junkyard)
iff you are going to use a pair of twin t-3's, go with the 83-6 2.3 ford 5-speed like www.toohighpsi.com did. they are bigger than the chyco's. most old school junkyards want $50-150 for them if you can find them. the 87-8 turbo coupes used IHI's. quick spooling, but give out @ 4500 on a 5.0

[COME CORRECT]

Go to turbomustang.com they have carb section.

If your carburated there is a real easy way to set up a turbo on your engine, in the earily 80 GM had a draw through style turbo system on the earily carb 3.8 regals and the V8 turbo T/A's, I have a feew of these style turbochargers onhand, they can usually be located on e bay., the turbo actuall bolts to your intake,on top it has a 3 bolt flange that bolts to the intake, a adapter flange or plate can easily be made from some 1/2 in alumm or 3/8 plate steel and mounted to any 2 or 4 BBL intake, I have installed a couple on customers vehicles and noticed a 75 HP gain set at a measley 6 PSI with a holley 780 dual feed Vac sec.
if you decide to use the chrysler turbochargers you can usually find them dirt cheap because no one other then myself seems to offer the Mopar designed T3 flange on their manifolds , if you get a couple of the mopar turbos ill donate a couple flanges to you so you have a way to mount them up the whatever style exhaust delivery piping/manifold you use
Also Blow through is not as hard as it seems to be, you can easily modify a Holley Double pumper carb for unsder 100.00 to blow through boost, ill try to locate the link to the site that has step by step proceedures to modify a holley ,but any way you decide to go as long as you get a turbo set up on the engine you wont be disapointed!!!!!
