We have now developed a tapered throttle body kit for the Duratec engine. We took a standard new Duratec engine with no modifications other than fitting a set of uprated rod bolts & fitting an exhaust manifold of a 4-2-1 design. The engine was initially run with standard injectors, but they ran out of flow even when the fuel pressure was raised. We replaced the injectors with a high flow affordable injector, which would fit into the original injector pockets. These also have the advantage of being able to cope with increased performance if you upgrade your engine further and would cope with power in excess of 280 bhp.

We were very pleased with the results from the standard Duratec even though it didn't come up to the power of the 2.0L XE, you must remember that the cam shafts fitted to the Duratec on the standard engine are designed for emissions and a cam change at a later date will release more performance.

The kit comprises of all the parts shown below. The MBE Ecu comes already programmed & ready to use. Read about the kit in Classic Ford, 'The 200 Club'

Fuel Regulator Options

The kits come with a FR1 fuel pressure regulator, however if you are anticipating upgrading the kit in the future we would recommend you choose one of the following options;

FR2SB Fuel regulator with high specificiation internals with consistently accurately maintained fuel pressure on high usage fuel systems, black top, supplied with -6 & -8 loose couplings. (shown far left with bracket)

FR-3.5 & FR-MNT Fuel regulator 3.5 Bar (51.45 PSI) & mounting bracket. (shown left)

Barometric Sensors

If you are likely to be using the engine in situations when you are at altitude ie. travelling abroad in the mountains, then you'll need to run this sensor to adjust the fuel mixture to compensate.
