Carberated TURBO 2.2?

oh yea. because when you need more fuel, YOU NEED ANOTHER CARB!!!

Thats isn't what I'm talking about though. You're talkign about fabbing up an extra manifold when one already exists. I'm saying that if you get the parts that you need, you can modify any carb you want to fit.

Are you talking about with an MX6 or the thousands of others that are running the same way? I have a friend with a twin turbo 7L Mustang dynoing 1,200-1,400 hp with two GT40's using a carb setup. They've been doing it for years. Just because you owned one carb'ed beater does not make it a bad concept.

Which is exactly why I wouldn't. I wouldn't even attempt to do a FI setup with acarb on the MX6 for obvious reasons but it definately can be done using existing parts. Would it be worth the time and effort? f#%k no.

Brandon- I was doing this years ago. Carbs, EFI, all of it. I'm lucky enough to be a few years older than you and have been driving since the "times changed". I as opposed to you have owned only one non turbo automobile my entire life. Everything else has been turbo, including carb'ed turbo.

Compared to EFI it's a walk in the park. That still does not mean that anyone would or should be willing to go out and try to convert an EFI vehicle to carb'ed turbo. That's nonsense in every way shape and form.

that makes more sence Six......I thought you wanted me to put that POS carb on there.....
And yes your right about switching from efi to carb.......
Guys were doing that with mustangs untill they found out they were slower....
as far as a holley for me, umm, well, I have a 650, (2) 750's, and 850/750, a 1000 race demon..... I have alot too choose from if I went that route, which is doubtful.....for obvious reasons.....
And carbed turbo's...yep, I remember my 81 LeSabre Sport Coupe with the 3.8 turbo.
The carb was chewed, and the car was way to rich on an idle, but put it too the boards, and that old boat would fly!!

No, you could use parts that already exist. The carb could be whatever. The hard part would be tracking them down:



I just found out Radinov has one:

[Robs626HB]

i really was just wondering if anyone had ever tries it just for the hell of it and saw wwhat happen.. cuase I was pretty sure liek you said.. you can turbo a carb mustang and get ridiculous power with out all the elctrical crap you gotta go through somtimes..

[Robs626HB]

and tuning would be easier.. with the lacking of the accracy the electronic enigne contors gives you ina stand alone.. or whatever

Six did you notice that Radinov and the magazine both refer to his engine as a 2.0l 12v ? is this a mistake or is it a shorter stroke block like the FE3 with a f2 head.
Migh be a good platform to turbo charge.
But it sounds like that engine in its curent state would be the worst of both worlds, the limited rpms and flow of the F2 head on a block that makes little torque, not to mention the carb.

[Dutch]

it is in fact a 2.0-12v SOHC
i had one in my totalled red coupe.
this engine is seen the most here, the head is the same as a 2.2i-12v, cam is different, it has a mechanical fuelpump which is driven by the cam ( it has an extra lobe on it.)
see some pics here :

thanks

[SixSick6]

Yeah I saw that but figured it was just an error. Wouldn't be the first time a magazine has written something incorrectly on a car that they don't own. Ask the guys in Europe.

EDIT: Ahh there ya go. Frank was writing at the same time. What about the crank, rods, and the deck height of the block. How do they compare to the F2?

Karma owed to Dutch.
2.0l 12v, curious, does this have something to do with engine size taxing? but then why not use the 2.0l 16v.
When you say different cam is the extra lobe for the FP the only difference between it and the F2?
Is that lobe just before the distributor?
If so all the 88-89 Mx6/626 Gt's and N/A's have the same lobe (here), none of the probe cams seem to have them, the 90+ mx6/626 dont either.
Always wondered what damn engine that loab was for, I knew it was a mechanical fuel pump loab, but couldnt figure out what engine used it, the b2200 is an 8V head, the previous gen 626's were 8v...
Unless of course they made a carbed, 12v 2.2l also?

Did they offer the 2.0l 12v in 90-92 or did it disapear like the extra loab on the cam did here.

I am assuming that it has the same bore as the 2.2l just a shorter stroke?
It would make a cleaner powerband in turbo application, but crazy torque is the best feature of the F2T .

[SixSick6]

It's only there to fool you into thinking the engine is better than it is. It lies to the transaxle and differential as well.

[fredio54]

when will you bastards get it through your heads that the heads are not "mx6" or "2.2" they are just mazda 12v F heads. used on utes, cars 1.8,2.0,2.2 the works.

i was going to say >> new mani a must because dry != wet, but you are right, there are carbed 12v manis. still a sh|t manifold though, and who would want a carb anyway? easy? nah. harder than megasquirt if you ask me... but then again, i am a software developer during the day before i put on my overalls and work till obscene hours in the carport.

btw, the b2200 comes in 12v too and injected sometimes.

heads blocks. interchangable in the most part, and totally seperate.

N00b to mx6.com, first post, but I gotta say something. My current project is turboing a carbed B2200 with a .48 T3, humongous Volvo intercooler, blowoff valve from a 1993 subaru WRX (blows off at around 19PSI) All "ghetto," but less money means more time and more time means more research.

1. Yes, you can turbo a carb setup. Saab, Volvo, BMW, Mercedes, Peugeot, Ferrari, Corvair, Buick, etc? They all had very notable performance cars in their day and they were all carbed.
2. At low power levels (sub-300HP), carbs are not a limiting factor alone.
3. EFI is a product of two things: Emissions control and production cost.

4. Six, you keep mentioning "use any carb," which doesn't make sense to me. Carburetors since the early 70s are "feedback" carbs, which control aspects of fuel delivery (choke, metering, altitude compensation, etc) with vacuum sensing. They are not viable in today's market because carbs must be engineered/designed for the engine and application. Particularily in the last generation of carbed engines with "computers" (like my 1990 b2200), you can't slap any old carb on and expect all to be well. Sorry if that's not what you meant.

[tyler886]

I wish everyone understood that. I find it extremely funny when people bring in kit cars to the shop with 350 SBs swapped in, with a 750 double pumper bolted to the intake

Any reason you chose to go carb'd? For the price of any decent carb, you could buy a MS system and tune away.

Truth is, I simply feel like sticking this project out. The engine came carbed, and it'll stay carbed. I know, I know. Only 8-valve SOHC, carb is limited output... but my goal is only 200 WHP. Damn it, that british dude can get a V8 to 2200HP.... that's gotta be more than 100% increase in HP. 200HP shouldn't be too difficult and I think I've done my homework.

Right now, waiting on an F2T manifold and I believe I'll have to weld a T3-type flange on it.

If things go well, I'll consider upgrading the carb to a Weber or a Holley.

[fredio54]

you should get 200hp from it, but it might take some seriousish boost if you keep most bits stockish. the 2l 8v engine only makes 79hp crank stock. not sure what the 2.2 8v makes, but not too much more.
