    Question 4A-FC Carb Intake/exhaust On 4A-FE

    My friend has AE90/Holden nova with dead 4A-FC twin cam carb motor.
    I've been looking for cheap 4A-FC but no luck, I found a low km well price
    4A-FE injected motor and want to know if the carbi intake manifolds and
    exhuast manifold are direct bolt up fit?
    Also will it bolt up to the gearbox the same way?
    Engine mounts the same?
    Anyone know?

    I'd do a whole EFI conversion for her but she doesn't have the money.

    Gearbox and engine mounts will be no worries. Check the mounts and supports when you have the engines out. You can swap them from one block to the other, but given it's one fwd to another you shouldn't need to.

    I would be surprised if the intake and exhaust aren't a match, don't know for sure. Also, hold on to the intake and any efi stuff you get so you can finish the job later. If you've got everything attached to the engine, just need the loom, ecu, and fuel pump, all of which should be pretty cheap.

    Regards,

    Question Re: 4A-FC Carb Intake/exhaust On 4A-FE???

    Roger that!

    But I really want to know if the intake and exhaust are straight swap.

    Anyone?

    SamQ is the only person that comes to mind that has had extensive time spent on 4afe so you might want to ask him.

    Yes they are the same but you have to plug the injector holes and drill the fuel pump hole out , both very easy to do.

    Where do I get freeze plugs from for the injector holes in the head?
    Or is there another way to block them off?
