  • ZETEC ENGINE WITH TYPE 9 GEARBOX

    Some usefull info on fitting a Ford Zetec engine and a type 9 gearbox.

    Using the Zetec with front and rear wheel drive gearboxes
    One of the most common questions I'm asked is, "what gearbox can I fit to the Zetec engine?", and its a perfectly valid one, which I can hopefully answer below. If you're installing the Zetec in to a kitcar, or any other car, perhaps even a historic or classic car, then this guide should go some way to help you make your decision.

    Ford's silver top and black top Zetec engines have been fitted to Mk1 and Mk2 Fiesta's, Quantums, Mk1 and Mk2 Escorts, Anglia's, Orions, Cortina's, Lotus Europa's, Westfields, and all manner of kit cars.

    Ford (being the sensible people that they are) decided to stick to the same bellhousing pattern that they have stuck to since the 1960s. So for a rear wheel drive (RWD) application, you can use the Type-9 five speed box from the Sierra, plus an RS2000 bellhousing. One simply bolts to the other. Note: The Type 9 has a 1" 23-spline input shaft and the 2000E four speed box has a 7/8" 20-spline input shaft. The MT-75 (Granada) or T5 (Sierra Cosworth) gearboxs also fit on the Zetec.

    Zetec crankshafts are already machined to accept a RWD spigot bearing, which again simplifies things somewhat.

    To fit the Zetec engine on the front wheel drive (FWD) Type BC gearbox, simply replace the Mondeo Zetec 2.0 flywheel with the one from the Silver Top Escort 1.8 Zetec, and use the clutch cover and friction plate also from a Silver Top Escort 1.8 Zetec.

    And the clutch?
    The Silver Top flywheel should be used, as the later dual mass flywheel on the Black Top Zetec's isn't suitable due to their size and weight. The flywheel will need re-drilling to accept a Pinto clutch. Keep the Mondeo Zetec clutch cover. Use a sierra 1.8 CVH friction plate. Fit a ford spigot bearing, change the clutch release bearing to a capri part CT133 Quinton Hazel (available from most motor factors). A new spigot bearing costs approx £10 from Ford. For FWD applications, you should use an AP Racing 220mm clutch and clutch cover.

    You can get away with using a standard Zetec FWD clutch for RWD applications but, as the fulcrum point for the clutch release arm is in a different place on FWD cars, you'll find that in a RWD vehicle the clutch pedal will only have half its normal travel.

    Hi Bob,
    Thanks for that,- very useful. I am just considering that very change.
    Any comments about using engine management systems and exhaust systems? I'll be going from a carbed DOHC I4 sierra lump to black top Zetec.

      There is some more info and some very nice stickers from the zetecinside website.

        Hi Bob,
        I have fitted a 1.8 Zetec and an Omex 600 ECU and kit bought from Martin Griffith [YKC used to advertise this as a kit in "Pitstop"] and it works very well, no problems yet. Once installed the initial programme the kit comes with needs to be re-programmed to suit your set up. The conversion is a lot of work but probably worth it.
