    Not sure about that, but Modular Performance will have the 90* elbow to throttle body measurements soon.

    UPDATE!!!!!!!!!!!!!!!!!!!!!!!!

    Mike and John Tymensky at www.modularperformance.com have decided to make an intake for a 5.4L DOHC to accept the Eaton/KB/Works blowers! Looks like the Cobra guys can now swap up to 5.4L's and Lightning owners can swap on DOHC heads!

    Sweet huh?!?!?! :nice: :hail2:

    5.4L swap

    Does anyone know yet when this intake is coming out and will it fit under a 2 1/2 in. R hood. I going to do the swap one way or another but its just if its going to be SOHC or DOHC. I already built the bottem end of my 4.6 so I'll just switch everything over with the exception of rods. I just want to know what motor to get from the junk yard.

    Thanks
    Brandon

    Intake

    Intake will be available December 1st. Not sure if it will fit under a 2.5 inch R hood.

    You will need a 5.4L crankshaft as well as rods and you must use Navigator 5.4L heads to use this intake. They have larger intake ports than any 4.6L DOHC head, and this intake has Navigator intake ports.

    Get a 2001-up Navigator engine. Check to make sure it has a forged crank because they stopped putting forged cranks in them some time around 2001 I think. I have a Forged crankshaft PN# if yours is cast on my homepage.

    Regards,
    John

    Check your pms i have some questions...I'm confused as to the intake part. Wouldn't a KB replace the intake and wouldn't it be a waste of money? I thought you couldn't bolt on the KB to the DOHC heads? I sent you a pm asking you some questions so get back with me when you get a chance. If indeed with this setup i can swap a 5.4L motor into my GT (dohc) and then install a 2.2L KB then thats what im looking for!

    The KB/Works/Eaton all use a lower intake manifold. The Modular Performance Blower intakes aren't ready yet. See www.modularfords.com Terminator forums for a lot of KB on 03 Cobras. Yes they fit 4.6L DOHC's.

    Will fit, only mods to accept the 5.4L would be slightly bending an AC line out of the way, Stock Cobra exhaust manifolds slightly grinded on pass side with custom h/x pipe, or Custom longtube headers with H/X pipe, and hood to clear.

    As one guy said, "an Eaton/Works/KB on a 5.4L DOHC would own, period!" A single/twin turbo would be even better!
