My injectors just arrived which i was assured were Nismo 740's. After removing them from rusted fuel rails (-6 phase 1.5 type as in pics) i noticed they're made by 'Denso', seller did state to me he had only just taken these out of his running car 2 weeks ago?? (hmm rusted rails).

Now i am aware that Denso did make quite a few early injectors for Nismo but not sure about these as i would have thought they would have been stamped Nismo.

Anyway they are Red with 'Denso' stamped on one side and '12 332' stamped on the other side of them and they have '2450' stamped on top the injector. Some pics to help, so could anyone clear this up for me? As if they are not Nismo i would like to tell the seller so. (but want confirmation first) Thanks in advance.








Sorry the pics aint great and a little fuzzy, not a good cam for close ups.

I will have these tested and cleaned but need to confirm if these are any good?

Bump

 

They are not the Nismo style 740cc injector.

They are either a 550, or 850cc phase one injector.

 

Mark, are'nt those phase 2 injectors with adaptors near the pintle end for ph1/1.5 rails?

Also just to add the pintle cap is nothing like the nismo 740's I have

 

Could anybody actually tell me if these are 550 or 850?

The injectors will be controlled by an Apexi PFC and i am going for 500BHP, i'm presuming the ecu may not be up to the job for the time being, but if it cannot run these then there is absolutely no point in me keeping these injectors.

Anyone?

 

Mark, how much is the cost for cleaning, flowing and testing these? Just weighing up the options now. They do have adapters (aluminium discs 1 large 1 small) held by the O rings.

 

I asked Mark that question a few weeks ago...

 

Thanks Bud, i will get these off to him for testing and see what happens. If they're no good then they will probably go up for sale. Oh well.

 

Funny how sometimes the fingers, and brain don't work together

Yes, I meant they look like phase two, converted to phase one !

 

You obviously have far to much on your mind, hence why you should join me for a drink Mark.

 

Looks like they may be 850cc.
