OK fair enough, just a thought.
I'm comparing it to my other car - a Rover 45 Turbo Diesel. These have 210 bar injectors and with standard fuel settings put out 100BHP. Simply switching to the 200 bar earlier injectors running standard fuel settings increases to ~130BHP. Add a remap, and 150bhp is usual. I understand they are completely different setups though - the Rover being direct injection and using the VP37 electronic pump.

Hi,
I'm new here but I've purchased some new GTD nozzles of the German ebay. My old injectors are quite charred up so I would like to refurbish them with the new nozzles installed. But how much bar would you guys recommend? Stock is 150 bar right? Think 170 bar is a nice middle way or do you guys think its a waste of time?

I must rebuild my injectors and have stock pump. So the 293 are stock nozzles ? The GTD are 273 = monark nozzles ? and which are best ? I heard too about nozzles from bmw tds DN0SD318.

My project car will have 1.9 xud nozzles set at 175bar...
I put the injectors in the daily car for a few dozen miles and it was the quietest d24 i have heard. I had tried some '4S1' nozzles at 155 bar with a hope that they would fuel enough....dont go there... Standard injectors flow 35cc over 15s 4S1 nozzles st 155 bar flow 70cc over 15s Xud nozzles at 175 bar flow 45cc over 15s

I have the same problem, using a genuine bosch 12mm head, 4s1 nozzles are out of an old lister diesel, 800cc per cylinder. With them fitted, it idles like cummins does, has a no load flat spot at 2500rpm and smokes like a train on the same fueling that standard injectors only just smoke under full load, sounds terrible under all circumstances. AND makes noticably less power than good, slightly worn stock injectors. Maybe if you ran 40psi+ and raised the pop pressure to something insane on those nozzles it would suit 0m603 power levels. but for what we can prove a d24 can handle, There is a limit to how big the injectors can be. And those 4S1 nozzles are above that limit! The 1.9 xud nozzles are plenty big enough for any power number that anyone has ever reached before with a d24, and even more than that. In the uk, people get 300bhp+ out of a 1.9 xud on the same injectors. Add a bit more capacity and two more cylinders. Should be good for 330+bhp. Im only planning 260 bhp and VNT boost, so im torque hunting mainly... 480-500nm hopefully!
