One standard BBR 1600 Turbo.

BBR used the stock airbox and airflow meter.

A small intercooler sits behind the radiator.

The turbo manifold's neat design allows the turbo to sit as low down as possible...

...this ensure exhaust gases have a straight shot out from the turbo, minimising backpressure.

The Factory wires are diverted into the BBR ECU. The injector pulse width and timing are altered under boost.

The stock ECU...

...is replaced with a programmable FM Link ECU. The BBR ECU is discarded.

Changes need to be made to the injector harness to allow for sequential injection.

Two new wires are added to injector plugs 3 and 4 and run back to the FM Link ECU.

Whilst we were at it, we added new trunking and sleeves to the whole loom.

The injectors were replaced with RX-7 460cc/min. These can be plugged straight into the MX-5 loom.

We've added some more trunking to protect the new wiring. Under there is an extra fuel line for the dual feed rail, knock sensor/injector wiring and MAP sensor reference.

The proper location for the air temperature sensor is after the intercooler. The standard BBR didn't use the normal idle air control piping, so we added our own and housed the sensor in there.

A spare boss was left on the intake piping, so we added a blow off valve and used it to recirculate the air back to the intake.

One of the best mods, was to add a cold air box. We modified a FM box and completely sealed in the filter.

The completed project.
