View Full Version : We all know KA injectors are junk.

So anyways, my injectors were getting stuck open and such on my KA, and Ive had enough experience to know that the stock injectors are destined to fail.

I had a set of extra's from before I put an sr in my old car, and was going to swap those in when my buddy told me he had an intake manifold from "some KA" lying around. I went and picked it up, but it was dark so I really didnt get a good look at the injectors.

Today I decide enough is enough and pull the manifold out of my trunk, and low and behold the injectors did not look anything like the 240sx red injectors. In fact, they looked like this:

Not knowing off the top of my head what these actually came from, I did a little research and came to the determination that the are off of a 98-04 nissan frontier.

Now obviously the two injectors are totally different, but looking at the fuel rail from my ka, i figured that it may fit. The only thing I really did over dropping them in was take the top injector o-ring and roll it up to the top of the frontier injectors, for an extra amount of seal, and then put them in, tightened them down, and put the rail back on my car. Started right up, runs good, no leaks so far.

Figured Id throw this out there for you guys since the injectors are a newer design, do appear to work fine with our rails, and are green, which is totally cooler than red.
Of course If anything goes wrong with this Ill be sure to update the thread.

I've been putting off new injectors for a long time. Keep us updated on how well they work.

well... frontiers also have ka24de's so it doesn't surprise me that they work.

ahhh yes. This is a great find--seeing as though once every two weeks my number one fuel injector likes to stay closed during start ups; leaving my KA with three cylinders for the rest of the day.

Do you know what the flow rate is for these injectors compared to the stock 240sx injectors?

Was not able to find the flow rate. Drove the car all day today, runs like a champ, no issues, so I would say this is a go.
