So I wanted to put the car back otr better than before, otherwise it wouldnt be worth it, tried a gt15 this time with fmic on the new engine, lots of torque but no real power/legs imho. So I started to read about diesel tuning in prep for a big build, first up was learning the difference between di and idi then getting more from the bosch pump.
I rebuilt a pump many times over before it was right but basically it ended up a 22mm shaft 306 casing, 11mm head/plunger, modified advance piston for more travel and shimed governor spring, heres some pics:

Pump mods:

11mm head assembly from transit:

Plunger difference:

Swapped gt15 for k03 for temporary as it flows more supposedly?:

Also fitted a hdi gearbox but cant find pics
