I need a set of 4 used injectors, Picos, Not coded either, so I can start up my engine build....

Renault used Pico injectors, maybe you can find some at ebay.

You don’t say what size you want but the meg 225/R26 uses 440cc and they are only £125 for a new set there are loads of used ones floating around but they will need cleaning. It’s common for them to develop a lumpy idle.
