Hello
Sorry if the question has already been answered but I would like to know if the 99 euro fuel rail (with return)+ NA8 injectors and an AFPR can be used with the NB2 square top intake manifold?
I did not find a precise answer for this subject...

Thanks

 

I am using a U.S. NB1 fuel rail with a square top manifold all on a VVT head.

I’m using Flowforce injectors and the factory fpr though.

 

Thanks for your response Efini
So, it should not be a problem with NA8 injectors on EURO NB1 fuel rail (with return)

You think that I'll need NB injectors or actual NA8 should fit?

 

Just curious, why use NA8 injectors?

They flow less than NB ones, and are an older design so from memory dont atomise fuel quite as well.



If you have an NA8 then I assume you'll also be using an adapter to fit the squaretop to the head, which means that the manifold will sit slightly differently to the way it would on an NB head.

 

Because when I swap the head for 99', I reused the NA8 injectors but I think I will change soon.
I know but at the moment I didn't have NB injectors

 

Are you in Australia?

if so i've got a spare set of NB2 injectors, $20 + post and you can have them.

They've just been on a shelf in my garage for years as spares, should be fine, but i'd recommend getting them cleaned before use.


edit:
disregard that, just remembered you're in France.
Postage will be too high to make it worth it.

 

Don't worry brah
Thanks for the offer!



Ah yes, before I forgot, I reused the NA8 ones because at the same pressure, they spray almost the same amount of fuel.

I think it is interesting to change them by NB ones when you raised the fuel pressure around 60+psi (apart from the fact that they have a better spray pattern)

 

The rail should work fine. I have a spare set of NB2 OEM injectors, and I am in Europe if you need some.
