pug 306 td injectors in a 1.6 td vw would this give the vw more power . or is there a stock injector out of a nother car that would be beter ie for more power
not sure about those, but there seems to be mixed feelings about Merc 300TD nozzles. some say they flow more and make more power, others say the difference is negligible. I picked up a set of GTD nozzles but havn't installed them yet. Either way, new nozzles will outperform worn out ones.
306 / zx dTurbo nozzles and 1.9 gtd nozzles are very similar. The PSA nozzles are designed for 185 bar opening though so may be a bit tighter in spray pattern.
Go for sprinter or merc 300 ones as suggested, I had both of these and they gave a 300rpm idle rise on the 1.9 pug engine. Merc ones seem to be a bit better for top end though, they are probably higher overall flow. merc dnsod265 with 185 opening is the best compromise i have found after using 135bar, 155 bar, sprinter, standard and merc. i use 50% veg though.
