Need the part numbers off of both. Bought some injectors which were supposed to be 555s, fitted them to the car & they ran like crap - very lean.

Have taken them out of the rail & they are completly different colour to Nismo 555s & they have Nissan part numbers on them.

Am trying to figure out what these injectors actually are before I waste any more money on them.

Did you get a remap for the new injectors ?

Yes, chip was fine & known to be working in another car with Nismo 555s, if I'd used stock chip it should have run rich anyway.

What numbers are written on yours ?

Nissan Logo then 1M51 2428D

 

Also has A4600 whch is the gauze filer p/n

Thanks Mark that is exactly what I was after. I have just taken out my injectors and I need to get them cleaned and flow tested and needed to know the original flow rate. Also one of my injectors has been replaced by another JECS unit but it is grey (my others are all red). Mine are coded 2M40 where as the grey one is 1M51. The guy I bought the car from told me that it was out of some Holden - I can only guess it was a VL non-turbo or VL turbo? Where did you find the info for the flow rate - I looked everywhere? Thanks again. Cheers. Clive.

 

Hope this helps

Probably best to get one of them flow tested. That will remove all doubts
