306 2.0 hdi 16v

You need to check what engine the new nozzles are off, then check if the injectors enter the head at the same angle as your 2.2 head.
If they match then you should be fine, if they are the wrong angle I'd keep looking.

16v is zero plane, from what I can understand there is no angle on the base of the injector seat, unlike the 8v head.

The 16v is zero plane, angle of injector dosnt matter.

Its interesting your injectors are 153 degrees, as the bosch managed ones (35/40 head) run a different angle... DLLA or DSLA makes no odds in terms of fitting / working, just the way the nozzle works. Either will work, DSLA are more common these though...

The 153 degrees nozzle is from a friends Peugeot 307 2.0 hdi 16v ( RHR Siemens injection). I got the injector from him and found out that the RHR engines uses the nozzle at 153 degrees.
I am current using the DSLA 144 nozzles and injectors from the 4hx engine and think that my lack of power is related to this diference on spray angle, because I use the pistons from a RHR engine.

Today I took off one injector from my engine and fitted the siemens nozzle on the bosch injector, my surprise and car works just fine.

Any any help with this is pure gold for me, so much work time and effort on this and the engine is not producing
