View Full Version : 1JZ feul injectors

03-10-2014, 02:30 PM
Just wondering has anyone used the stock supra injectors from the 91 to 92 supra? Will the support a turbo kit.

I will be keeping it N/A until I get everything for turbo kit. And will be getting the walbro feul pump. Is there any tuning that has to be done if I went this option?

I want to try and avoid spending the ridiculous amount of money on injectors for the 3sgte or 2jz injectors.

I honestly don't know how well they'd work for whatever it is you're trying to do, but if you want a set of JDM 2jz injectors (side feed 440cc/min high impedance, IIRC), I have some you could have pretty cheap.

how much? Do you have pictures? Will they support for a turbo when I do the Forced induction set up?

Oh I don't know, $50 for the set of six if you want them. The injectors don't care if the car is turbo or N/A, but what you're really asking is if they would flow enough for what you're trying to do, and the answer is most likely yes. If I recall correctly, that's approximately the same cc/min injector as 3sgte's use stock. I can take pictures if you want.

^ Stock for the ST185 3SGTE is 440cc, ST205 is 540cc

Do you have a pay pal account?

And will they plug right up to stock harness?

Umm, I'd make no claims about fitment in whatever setup you're running, cause I just don't know. I only know what the injectors are/came out of, not everything they'll plug into. However, I believe I have the pigtails that I cut off the engine harness that you can have if you want. I'll take a pic this weekend and you can see if you want'm.

ok thanks.

Is this for your 5sfte your building? Power goals??
The 5s uses top feed injectors. Search for these
89-91 RX-7 NA 460cc (high impedance) Red Top #195500-2010 . These are direct plug ins on the 5s

If you're building a 5S-FTE or similar build, you really should ALL of presure2's build thread over on 6gc (http://www.6gc.net/forums/index.php?showtopic=23187&st=0).

You will find a LOT of information there that will give you an idea of what to expect, and what you need to look out for.

Oopse, forgot about this, but yes, if you need top feeds, you don't want side feeds unless you're planning on switching to a side feed rail. ;)

Also, 2JZ is 540cc. IIRC the 1J is 440cc.

Not the JDM 2JZ. They run a significantly different setup. USDM are 550 and they're low impedence and run a resistor pack. The JDMs are high impedence and 440. Why? I really don't know, but they are. I converted my JDM 2j to top feed. Originally I used some precision low impedence that I already had and ran the USDM resistor, but have since switched to ID1000s and an AEM v2 that handles the injector resistance internally, which is why I have the side feed 440s laying around. Anyhow.... yeah, probably not worth the trouble to use if it's a 5sfte the OP is working with (unless maybe he's switched to a side feed rail already)

Yea not really planning on switching the rail. Mr.Tauri said 7MGE and RX& would work up to 300 whp. anything that would work for round about about 400whp?
ill be running a turbo.
