It's a 1990 Fiesta RS Turbo, the 1.6 CVH one with the small T2 Garret turbo. Should run 8 PSI stock if I'm not mistaken and the actuator is mechanical. That's a good idea using a tyre gauge, will see if I can hook it up there.

Burton has no longer short shift kits sadly, the stock parts I'm looking for are the ones described here:

2 * Catch assy 6172154 (return spring holders)
2 * spring, lock 6193756 (horizontal return springs)
2 * screw, pan head 1648726 (return spring retaining screws)
1 * bearing, gear change lever gate 6192095 (bush for the change rod)

Some are available at autodoc.com, the reference matches but I have had wrong parts delivered in the past. In any case they should be common with any MK3 Fiesta that used the BC5 gearbox as far as I can tell, so they should be readily available as gazillions of those were produced and many I guess are still running around.
