Bought these a while ago of another fellow 'liner owner. Gonna be building my 500bhp+ build soon, however not too sure about the Authenticity of them.

I was / I'm assured they're Blitz 650cc injectors (blue top with Denso written on 'em). They don't say Blitz anywhere on them, just Denso in small embossed writing. Anybody know if these are the real deal or have I been stitched up?

I think its hard to tell.

I got some light blue injectors. And they are different thing by different manufacture.

Light Blue color:
HKS: 680cc
Denso: 700cc
PWE: 720cc

How can you tell if they are all made by Denso, all have no marking on them, and all are light blue color??? Do they have a different part number written on them? Or does manufacture just quote different things for the same injector?

Mine were light blue aswell, claiming to be SARD 700cc injectors - again they just said Denso on them and a number :)

Get them flow tested, its the only way to tell for sure.

The blue on mine is medium to dark in appearance, defo not light blue. They've also got some very small numbers on 'em. I'll check later 2nite when I get back.

I think i have the same injectors. Dark blue with Denso written on them.
I did a search and found out they are 680cc @ 3bar fuelpressure.

Just search on the number and you will find a list...
