This kit is the basis for the upgrades in the 1.4L taper throttle range & the MBE ecu comes complete with a program allowing you to be ready to run immediately. We have had reports that adding this kit to the standard engine can produce between 125 & 137 bhp dependant on your engine version.

INJ-744-P InjectorThe standard injectors fitted to the 1.4L 16v engine are unable to supply enough fuel to cope with the improvements in power that the taper system adds to this engine, so they have to be replaced. We use the Bosch Blue injectors, Part No.0280 150 427, as fitted to the 2.0L LN engine. These should be readily available from breakers yards, if not you can buy them from us.

The wiring harnesses have been specially designed to be as neat as possible and are available in front or rear wheel drive layouts to cover as many applications as possible, when ordering your kit you should specify whether your car is front, rear or mid engine layout.

If you are aniticipating upgrading the to +30 bhp in the futrue, you may wish to choose to use the smaller high flow peco injectors, these require a different fuel rail which can be substituted as part of the kit instead of the standard rail.
