    Default 1980 Capri RS Turbo conversion to T-bird inject motor

    I have this 1980 Capri RS Turbo with the original engine (Marti report should be here by the 27th). The engine was taken apart by previous owner and is missing the carburetor. It is my understanding that this carb is a Holley Webber 5200 series and kind of hard to find. Will a Holley 350 cfm 2 bbl carb work?
    But what I really want to know is ..... I have a '87-'88 T-bird turbo engine and 5 spd tranny with ECM and Ignition Module. The wiring harness is a mess from the T-bird and in some cases missing. My question to the group is what is needed to install this t-bird engine in to this carb car? Is it as easy as buying a Detail Zone / Ron Francis wiring harness ($475) and a installing an inline 255 gal/hr fuel pump? Stinger performance tech articles really don't cover the carb cars, only '83 and up.

    Your gas tank might be a problem. Pre 82 (?) had a different strap location and size. I don't think you can just put the pump in the older tank. Also I don't think there is a return line in the other cars, you'll need that for the FI. (Yes, I see you said inline, but I don't think that will work)

    I'd also research the 'hump' in the transmission tunnel. Not sure if you need to add one to an older car for a T-5.

    The battery will need to be moved for the VAM.

    Otherwise the computer and wiring harness are pretty much independent of the rest of the wiring in the car so it should work.

    I'd also go search/join TurboFord. There are a few early 4 eye projects over there.

    As far as the Holley Weber 5200 being hard to find, it's not. The same carb was used on lots of standard 2.3s in the 70s and 80s. The 350 two barrel can be made to work, but you will need an adapter for the carburetor. With these old carbed turbo engines, it is a lot easier to use the factory parts.

    I agree a 5200 is not hard to find, although the turbo engine version is much less common.
    So is info on them.

    The 2.3 turbo carb is calibrated differently plus has some physical differences required to correctly work with turbo engines.
    The top air horn casting assembly part of the carb is the major difference physically.
    Also possible these may be the larger venturi older version of the basic 5200, with turbo mods added.

    "The Holley 5200 was a license built copy of the Weber 32/36 DFAV 2 barrel (2 venturi) carburetor.
    This carb was also produced by Motorcraft under license.
    Most 1972-74 V-6 Capris and some 1971-74 Capri 2000 SOHC used this carburetor, although the V-6s used larger jets.
    Both types had a flow rating of 270 CFM at 3 inches of mercury.
    The 1979-82 "Fox" Capri 2300 also used a version of the Holley 5200.
    It had a 23mm primary venturi instead of 26mm, and had a flow rating of 235 CFM at 3 inches of mercury."

    A good regular n/a 5200 can work ok if certain parts are installed along with reroute of some vac lines.
    Along with lots of patience and head scratching.
    And until a correct turbo version carb is found, the best choice.

    A 5200 can be found online, special ordered, or salvaged.
    Have gone thru 5 or so carbs over 30 years, sourcing from all 3 ways.
    Had success keeping the car on the road reliably.

    Current carb on mine is a correct turbo version. Engine runs fine like it did in the 80's.
    Same or slightly better fuel mileage (solid 20+).

    Finding another carb has to be less work than the alternative if that is all that is missing.

    I am also missing a flywheel, but i believe a norm asp (n/a) one would work. However, I noticed that the turbo exhaust impeller (hot side) is not spinning. Can these be rebuilt? I would prefer to stick with the carburetor engine and keep the car original.

    I didn't realize that the turbo carb was different. The two turbo cars I had were the same as my regular 2.3 Mustang, but maybe they had been messed with or Ford made a change over the model years. Yes, an n/a flywheel will work. The turbos can be rebuilt, should be a diesel truck shop near you that can do it.

    Has anyone tried the DGV 5A 32/36 weber? They are plentiful and inexpensive.
    Did the DFEV or DFAV in the 80's have electric choke or coolant temp choke?

    The carbs look identical at a quick glance. Same air cleaner housing.
    Closeup, there is a vac connection at the front next to the purge valve, and another on the carb pass side up by the choke assy.
    They for sure affect how the carb works and how the engine runs, if at all.
    N/a do not have these extra connections. Somehow i got them to work.

    There also are Calif feedback versions. 6500 series
    Ford (5200/6500), GM (5210/6510), Chrysler (5220/6520).

    http://www.redlineweber.com/html/Typ...ght_choice.htm

    2x on the turbo rebuild. If going that route, make sure rebuilder marks and reclocks the turbo assy exactly like it was.
    Be very careful when torquing the turbo assy down to manifold.
    The cast aluminum adapter, underneath the center section, cracks easy.
    Especially if turbo was not clocked right.
    Big time oil leak at the least.
    Yah it happened to me.

    Thank you gr79 for your help. It is greatly appreciated! It looks like I have to go with the Part No. 22680.160 32/36 DFEV.

    Default 2.3 carb confusion

    Decent price for that new one. No pic?
    State, to whoever you go with, it is a turbo engine.

    My current carb was bought on Ebay. Used. Works perfectly (after cleaning).
    Better than the reman Holley ever did.

    Dunno if a regular 5200 will work very well on a boosted engine.
    Turbocharged engines came with a turbo specific carb.
    Internal parts are calibrated differently.
    Air horn has added connections.
    Read somewhere this allows the extra fuel needed under boost.

    Special ordered the reman from Pep Boys. Came in a Holley box. 64-3213
    The oem carb id tag was needed to pick the 'correct' carb.
    Problem was the carb body was correct, but had the wrong jets (too small) installed.
    Turbo carb body, generic 'one size fits almost all' inside.

    The pic below is current used carb, 1979; 1980 prob similar.
    Shown with entire choke assy removed.
    Note extra connections for vac lines.



    This one says for 79 2.3T (and that 64-3213 interchange number).
    Accelerator pump arm is pinned at the #3 (lowest hole) as shop manual specifies is correct for turbo apps.
    http://www.ebay.com/itm/1979-FORD-MU...p2047675.l2557

    The same seller lists one for 1980-82
    Visually looks to have the turbo carb air horn on a N/A carb. Note the blue caps.
    Inside parts???
    http://www.ebay.com/itm/like/2913346...lpid=82&chn=ps

    For accuracy, used my carb tag number as if i were buying another carb today.
    Further research on Rock Auto site, Autoline brand:
    1979 Mustang/Capri T/C use same carb number. The tag number matchs mine.
    1979 Mustang/Capri N/A use same carb number
    1980 Mustang and Capri N/A manual trans different # from 79, auto same as 79
    1980 Mustang/Capri T/C no listings

    Autoline brand appears to be more specific in apps.
    Other brands seem to list same carb number for all apps. No tag number matchs for mine.
    NAPA blew it showing Escort carbs
    O reilly, AZ, out to lunch
    Pep Boys site temp off line
    Advance good (Autoline brand).
    The ebay Northwestwholesalers links look most interesting.

    Conclusion- if i were to buy a another 64-3213 for my car, the carb body might be correct with generic parts inside.
    Then open it up and probably install/transfer parts. And change the pump arm pin to the lowest hole again.

    Wow gr79, thank you!! Your are providing great detail for me.
    So is the OEM Carb ID tag #64-3213? Can you get bigger jets if the new carb has the incorrect ones? and what should the jet size be?

    My carb id is D9ZE-MD
    64-3213 is just another generic interchange number used on auto parts.

    Several other recent and older posts have more details on the parts:
