Seems good, first short tst drive confirms its ok. The spare car blk dots do have lots miles but still report on duty even though all have a crack in the base of the nozzle brown 'shield' -part.

 

Eh Ive heard that a crack on the nozzle is not good

 

The spares are on the last leg; 250kmiles on them. Does the job until a new set is found: local nissan charges 300$ apiece. (Think positive: Would triple that maxima value.)

 

$100 a pop over here, just need to get them past customs over there

 

One day I am going to need a set of bigger ones (is that 300zx?). Does price level stay the same? Will the std ECU accept them?

 

you'll need a differently tuned ECU to use bigger injectors. 350z for example has 370cc i think... don't quote me on it tho. but while the ECU can compensate a little bit for a whole set of slightly-different-sized (bigger or smaller, maybe 5% difference or so) in closed loop operation... once it's in open loop you are going to run rich or lean (depending if you have larger or smaller injectors, respectively). Stock ECU already runs a bit rich at WOT as it is... making the injectors larger on a stock ECU will actually reduce power output.. which is why some people actually drop their fuel pressure a TINY bit so that the ECU will keep it at 14.7:1 when cruising, and be at like 13.0:1 at WOT rather than 12.0:1 or whatever it comes out to be. of course then you need 93 octane and a good KS to pull that off.
