I think it was Dave (935racer) who ran both stock and merc nozzles on the dyno, and lost ~5hp, IIRC with the merc nozzles. I see the some of the europeans mention biodiesel nozzles as being better, but I'm not sure which number those are, or what makes tham better. I believe Giles swears by the stock nozzles, although I do recall seing mention of a GTD nozzle as well.

Arb, you're just the person to build your own injector tester from a bottle jack and replace your own injectors.FWIW, I get the earlier TD nozzles from autohausaz.com and rebuild them to the *low* end of the pressure spec for best fuel economy.I use the DNOSD293 nozzles which were spec'd on some vw IDI TD engines and yet are quite inexpensive:http://sd.autohausaz.com/autohausaz/detailw.jsp?sid=3vjolwfmvksbhdytprkjh155&partner=autohausaz&product=0434250103After buying the four nozzles you still have to toss in an oil filter just to meet the $50 free shipping.
I just got Prothe to refund the 4 merc injectors too. when the credits hit, I might drive up to partsplaceinc and get a new Brazilian made loaded new 1.6L hydro head for $600.
