2.3 carbed turbo blow thru 2bbl
« on: April 18, 2012, 10:35:45 PM »
looking to boost a 78 2.3 carbed motor.
here are list of the plans.
stock 5200 2bbl, with a solid float, or one that will not collapse.
small t25 or t3 turbo.
only 7 psi.
boost ref. the stock mech. fuel pump.
maybe lock timing for not much advance.
build a simple up pipe off the stock manifold, a carb hat and the pluming/piping.

i have build many turbo set-up on fuel injected cars/trucks, ranging from fmu set-ups to megasquirts, small turbos to big turbos,ect,ect but never a carbed one.
i want to do this and do it on a budget, with mostly left over parts from past projects.
my biggest questions are geared towards the fuel set-up and/or modding the carb for blow thru, i have not messed with alot of carbs in the past mostly efi set-ups.

so if anyone has any feedback about doing a blow thru carbed set-up on a 2.3 it would be much appreciated.

Go to www.turboforum s.com and check the carb section.
Also google Hanger18 Fabrications for a carb build.

I have a 306/carb bt/T70 Zephyr.

sounds like a good plan, i am currently building a 2.3 turbo motor from a 79 mustang pace car to put in my 78 bobcat wagon, basically the same set up you are looking to do. good luck

i have done some searching on there also, was hoping someone on here might have ran a similar set-up with
the motorcraft 2bbl, and or built a budget minded turboed 2.3 blow thru carbed car.
i would be even interested in info on draw thru set-ups, just for the sake of learning, but im pretty dead set on the blow thru deal.

any info and or links related to this would be appreciated also.

Never done a blow through 2.3 but have done a blow through Ford inline 250 six, 497hp and 501 foot lbs to the ground....
I would suggest going the draw through route,  your asking for trouble boost ref. the stock fuel pump, you'll also need to drill the power valve circuit to allow you to run a small primary main jet, (if you go the blow through way).

Draw through all you do is put that stock carb on jet it and go

Draw through with water, meth or water/meth injection, way easier, will make the same or close power, no intercooler piping, no intercooler.  way easier for a carb setup....

might run like crap until it's thoroughly warmed up. you have to watch out for excessive intake charge temps.

I'm running a 2.3T from a 79 Mercury 10PSI, MSD6BTM ignition, gonna bump it up to 15PSI here shortly when we swap it to a manual trans and an electric fuel pump.  Only issues I have now are fuel starvation

Back in the dark ages I was running a draw thru on a 2 liter originally ising the 5200 rejetted with h2o injection & 20psi boost, stock fuel pump. Issues I ran into were a prolonged warm up to normal running temp due to the carb being located so far from the stock intake & a bit of bad fuel distribution due to the stock intake as well as a hot intake charge at high boost & under load which caused detonation despite h2o inj & carb jetting.  I got hold of an equal length runner intake (a ford europe item) & stuck on a rejetter fomoco 2bbl from a ford truck. Was able to eliminate the occassional melted piston (welln OK, it was more than occassional!) As well as extend the ability to run full throttle under load with over 20lbs boost but still couldn't use 4th at the strip because of detonation. Never had any head gasket problems just needed better fuel distribution. Car was running low 13's at the time (1972-73) with 185-13's thru the muffler & never using 4th gear. It got good mileage too! I like the draw thru setup but FI is the way to goIMHO

 im surprised there is so much love for the draw thru, anyone on here running a blow thru?
im still undecided on which style i will run, but still leaning towards blow thru.

also i have heard some guys that run the holley 350 2bbl with a blowthru set-up (not necessarily 2.3's but other motors 4's and 6 cylinders) seem to have had good results, i do have a 2150a carb (369cfm) its from a 1982 stang 5.0 4 speed, that is a nother option.

A buddy of mine in So.Tx. has a 350 Holley bt with a
6 speed behind his 2.3T. It works well(over 400 last time
I talked to him.).

Yes, I,m running a blow thru with a 350 holley It runs very well,excellrates very smooth. I'm just running a stock fuel pump so It will starve for fuel when your boost gets up over 3# for very long. From a stop light It will run with a mustang in 1st gear and part of 2 second before it staves for fuel. After the stampede i'm going boost reference the stock fuel pump just to see how much it helps for now. My set up came from an 85 turbo coupe. I relocated the batery,had to cut a little of the inner fender for the turbo, I drilled a hole in the oil pan and welded a 1/8 in.plate with a 1/2 in. pipe fitting over the hole for the oil return line. Then I made my own hat to cover the carb. then run a piece of radiator hose between the turbo and carb. I didn't ask anyone for advice because most would say It wouldn't work well I'm glad I tried it. And right now i'm getting 27mpg. Oh I wouldn't be afraid to use the motorcraft.

If you don't have the money to do a blow thru correcty, then you don't have the money to replace the engine when you burn it down, if your lucky you'll melt a plug or pop the head gasket. Not trying to big an azz, I just want you to know your asking for trouble going cheap with a blow through. You'll need a EFI pump, a boost ref. regulator, and a fuel return system.

I wouldn't trust a stock fuel pump to 5 psi, and that's with it boost ref.

Believe it or not, when I rebuilt my engine about 12 years ago now I wasn't planning on a turbo. I saw the turbo coupe sitting on the side of the road I ask the owner and he said you want it go get it. That being said I'm running forged flat tops, The head has been milled .080 And I haven't even backed the timing off any. Iv'e had this set up for 4 years now. Last summer I finaly changed the plugs and no signs of detination. I know that much compression and timing should be devistating to my engine, I don't know why it works so well. In the beginning I just wanted to try the turbo out then work my way up to fuel injection. Last summer we was driving to a car show about a 130 miles away and I got a crack in the oil line to the turbo after fixing we was going to be late so we was driving about 80mph right on the edge of fuel starvation about 3# of boost and we got 27 mpg. On the stampede trip I'm planning to drive normal I'm hoping to get 30mpg.

Blow thru and 'on a budget' are two diametrically opposed things........ ........you're only making it harder.

You may want to go over to Turbo Ford.org and check out Joe Laramee

He has 2 pintos both are blow through turbo 4 cylinders

His "street" car is running 9 second quarters

His "race" car is running low 8's

It is a cool page as well

If I were doing this I would find an EFI Turbo engine and bolt the proper Carb stuff to it

The EFI engine has forged internals and is already a very tough engine

Good luck

that is what I am currently trying to build have a 85-86 tc motor, and going to use the head off my 78 wagon and the intake and exhaust off the 79 2.3t mustang. its been a slow process due to funds and time right now but just gathering all the parts is half the fun!! just picked up a roller cam for my head a week ago!!

good luck with your build!!!

i have build many turbo set-up on fuel injected cars/trucks, ranging from fmu set-ups to megasquirts, small turbos to big turbos,ect,ect but never a carbed one.

Then why start with a carburetor now? I would (or would have in 2012 when this thread started) get an MS-I v2.2 kit for ~$150 and go with a blow-through TBI setup on the stock (or similar) intake. I might do that myself with an MSII v3.0 just because I already have the ECU.

A new fuel pump is going to be necessary either way and, IMO, EFI does everything a carburetor can, only a lot better. You ought to have a wideband O2 sensor for tuning regardless of the induction, so factor in $200 for that whether you use a carb or EFI.

Regardless of what someone who likes to fiddle around and be different achieves (hey I get it, I like to do that too) an EFI setup over a blow through carb setup is just so much more practical. If it is being done for personal accomplishment - great. But otherwise if it is being done because one has "some" of the parts and they think it will be cheaper..., I doubt it. The "price" of difficulty and frustration may not be worth it.

I have tried both , EFI is the way to go if you can , but you can use the blow through but it has its share of problem ,  on the cheep a zoop through worked the best on the cheep , but you must use a turbo that has the seals for vacume on the carb side , did some early ones in the late 70s , later when the first turbo 2.3 in the mustang came out , worked at the ford dealer back then , those work kind of well for what they were ,  got to remember that they had to pass smog and last long enough to be out of warranty , they had a few issues but taken care of if you knew what to do , one was they were too lean and turning up the boost would blow head gaskets or melt pistons , the stock turbo 79 to 80 had forged 9 to 1 ratio pistons , the later 94 up efi had 8 to 1 , better head gasket , the turbo carb was specal , it had a remote power valve to keep the engine from leaning out too much when in boost , they mounted the carb on the intake side between the turbo very close to cut down turbo lag , I still stumble across these that are still running , a good test that the old 2.3 is a very good engine ,
