Really pleased to let you know that Jake Scammell driving a MK1 1st Gen RX7 that we have built and tuned the engine for came 1st in class and 8th overall in last weekends Tempest Rally.
Well done Jake.
Engine is a full bridgeport 13b with IDA 51 carb and Hayward Rotary Apex seals.
Here is a vid of the car at an earlier in the year rally.

Is there any way I can find out a bit more about the car spec ? I am planning a S2 build for sprint / rally use.
