Injector mounting ring for 300tdi injectors:
diameter 27mm 10mm high and a 17mm hole, 5mm holes trough and trough with M6 in it.
Use the ring to drill 2 holes in the injector about 2mm deep (first dry fit to find out the correct placement and keep some extra room for tightening) and tighten the ring with 2 M6x12 grub screws, now you can use the Hdi's original clamps to mount the injectors. (with use of extended studs and taller bolts)
With the use of this ring you can turn the injectors around any way you want so you can correct the spray pattern angle to match the engine.
Stock 300tdi injectors can handle up to ~200cc and have a 2 stage injection cycle with a pre injection at 200bar and the main at 300.
If you want more you can fit DSLA144P144 nozzles which have about the same spray pattern and angle but come from a Scania truck so can deliver a whole lot more. One minor thing these are 9mm diameter and originals 7.2mm so you need to drill out the head.
We use these as single shot at 320bar, grind the little pin on top of the nozzle needle, use a thrust piece from the Hdi's Bosch common rail injector (not from Siemens is different) mount it and start adjusting until you have them all 4 at the same pressure...
