Hey folks, so after searching the zilvia+the web I've come up with this:

90-96 Q45 uses 370cc sidefeed injectors.

However I also read that some of those injectors DO NOT fit in the KA24DE fuel rail. The differences where between 4-hole and 1-hole. Also some had longer thinner spray nozzles while others had shorter wider nozzles that fit the KA rail.

Somewhere else I read that nissan changed the injector design in 94-95?

My assumption is this:

Two designs of injectors where used for the 90-96 Q45 with the design change at 94-95 giving you early Q45 370's and later Q45 370's. There was confusion though with WHICH ONES would actually fit the KADE fuel rail.

Does anyone know which model's or years Q45 370's fit the KA24DE rail? Im hoping that someone has actually tried doing this and was sure of what year Q's injectors really work.

Searching around for which ones just confused me b/c all of the forums I searched gave me mixed results and misleading info.

Im hoping to clear up info on these b/c I see Q's in the junkyard quite often and probably would be a cheaper and more convenient option compared to sr injectors or 300zxtt!!

THANKS !!!

I'll give you a big hint they almost follow suit to the Z32 injectors that fit the S13/S14 fuel rail:

Z32 370cc injectors that work on S13/S14 rail are:
16600-21U00 from 09/94 - 10/96
16600-21U01 from 10/96 - on

so you'll be looking for those year Q45 injectors (hard to come accross atleast for me usually the wrong kind are available more.

Are these the ones with the brown/caramel cap on top?

Depends some that are beige are incorrect and some are the correct ones, there are light colored purple one also that are correct to.

Ahh, thanks. Since I got the brown tops and they have the Pintle caps... these must be the older 370cc injectors that won't fit my KA24DE. Thanks UNISA JECS.
