Title: NA13X or NA14X
Post by: wolf_walker on December 14, 2009, 09:46:09 pm

Ok what is the deal here, one is for early one is for late NA's, what's the diff?

Awhile back I ordered rebuilt Bosch injectors, got the 14x, ended up with
two rebuilds and two brand new one's, the body's differed in apperance, same numbers
on em.  I need to order another set but it has bugged me not knowing what
the difference is.  They are in a late hyd head motor, but with a 106AG early
pump. So..  ?

Stumped ya huh.  Yeah, me too.
I need a Bosch rep willing to email somebody who'd know.
They wouldn't have two of them just for the hell of it.
I want to know what the deal is before I buy another set.

Well my worldpac rep gave me an 800 number for a Bosch tech line(that I probly could have found online).
If I can ever get them to answer I'll ask them.

Anyone want to place any bets on them not having an answer? :)

I could be off, but I think the 14x had a different opening pressure??? I think that they all have the same nozzles and bodies so what else could it be?

I've also seen NA10X and NA11X-no clue what the difference is unless its pop pressure?

I know the NA 14X had two different types of bodys I got, two were rebuilt two were new.  Go figure.

Aren't the NA 1.6's all spece'd at the same pop pressure?  What is it, 135bar?

If its been rebuilt, the case marking is irrelevant.  The rebuilder may put a plastic dog tag around it, maybe.

Correct.  The body style was notably different between the new pair and rebuilt pair though.
I believe the rebuilds were dog-tagged and of the older body style I've been used to seeing.
