Fake VN V6 injectors.

[GeorgeM]

This is probably no news to most but I thought I would post my findings. Recently I had a need to flow test some injectors for a 4 cylinder Fiat motor and decided to build my own flow tester. After testing and ultrasonic cleaning the Fiat injectors I went to my VN injectors as I'd replaced the 0280150960 Bosch injectors for Ebay specials a while back, they are a newer design with green plastic body and have 0280155777 number on them and the Ebay site claims a direct replacement. The car ran on them but was a bit rough idling and seemed to use a bit to much fuel. My tests of the 960 injectors after cleaning were 28.5 to 29 cc in 30 sec but the Ebay specials are between 30.5 and 35cc per 30 sec. seeing the test results I'm not surprised with the poor running and wish I had not bothered to buy them.

Cheap chinese copies is a huge problem unfortunately.

The 777 injectors aren't a direct replacement as they do have a different flow rate to the older 960 injector, they are also a different design (EV6 Vs EV1).

When I looked up the 777 injector flow rate they are meant to be less than the 960's but the Chinese junk are way over and shouldn't be sold for a VN in any case, but they are still being sold. Had a quick search and for the bargain price of $36 you can get a set of 6 and they fit everything. https://www.ebay.com.au/itm/3746759...MIi5urrsS7gwMVCNkWBR38DwfPEAQYAiABEgLmGfD_BwE
How can they get away with it?

The 777 injectors where on the vt v6.
Those ones you have linked to in the above post, are more blue than green that the earlier vt v6 777 injectors where in colour.

Buyer beware. Definitely knock off injectors. Genuine would not be that cheap. Ebay doesn't care

The other issue is that there are 3 different sets of flow numbers about for the 777 injectors and you need to take into account that early models (VN-VS) typically use 3 bar fuel pressure where as the later model V6 motors are 3.5bar.

Do you have a multimeter? Try measuring the coil resistance and see if they all match.

I'd have to get them out of the bin to measure the resistance. I should have known better to buy them as many years ago I worked for a company that sold Bosch tune equipment and EFI parts as well as Injector testing and cleaning gear. I recall one occasion with a visiting Bosch guy for Germany commenting why we were selling injector cleaning equipment until the relative cost of new injectors in Australia was explained to him. Turns out that in Germany they didn't cost much more than a set of spark plugs.
