Kept the starlet cables and the starlet shifter - just needed to make an adjustment to the inside of the shifter to allow it to move to the reverse position on the g6 box.
im running 16" wheels, im running a 6 speed box on a blitz k24 externally gated setup, which boosts earlier than a td04 but is a tad laggier than a ct9 hybrid, and it flies through the gears. It does feel like the engine feels better under load on the 6 speed box compared to the 5.
