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!
