Someone tried 300TDi or maybe it was 200TDi nozzles, it was very very smoky, although that was on a mech pump, I can't remember details now, maybe it would have been better if it was tried on a VP30/37 pump with a proper remap and bigger turbo.
"SDi" injectors are the most commonly used, from the 200/400/600 (VP37) swapped over to a 25/45/ZR/ZS (VP30) gives good results, around 25bhp+ on a standard engine, as shown on that dyno graph I posted they're good enough for 180bhp at least although it has been speculated that more fuelling would have given better power up top rather than a very flat power curve - you're more of an expert than me though so I'll let you answer that one lol.
