eBay JECS Injectors - Too Good To Be True?

Hey guys - I've been seeing super cheap injectors on eBay claiming to be genuine JECS OEM products - usually for under $100. Now, obviously I take eBay descriptions with a grain of salt, but it's not usual for an eBay seller piles of listings/feedback to be outright lying on an ad.

Here's an example - $90 shipped for 'NISMO' JECS 550cc Injectors (see pic below). Are these really the seemingly good deal they claim to be? Or am I missing something here?

The description says re-manufactured, so they're probably re-drills.

And not even by a "reputable" company like Deatschwerks or Five O. They're no-name brand re-drills.

Two things in life always hold true:

1) You get what you pay for

and

2) If it's too good to be true, it probably is

Ahhh, that's the tricky part. Didn't see that. Some of them say JECS and "remanufactured" and then some of them say "new" but they're generic brand.



There are some that are both though. Here are new ones that say both JECS and that they are NEW OEM. Given, they're $165, but that still seems like a pretty good deal. Would you trust those?

when it comes to something as important as fuel injectors, DO NOT CHEAP OUT!!!! i cant stress this enough. with my last build back in 2006/2007, i went the cheap route and bout deatshworks injectors. went thru 3-4 sets because they couldnt handle E85. i got sick of constantly sending injectors back and forth... so i manned up, bought a top feed rail with some brand name US made top feed 1000cc injectors. never ran into another problem again!

my current build, i spent the money and bought 740cc tomei injectors for the simple fact that i knew i wouldnt burn these out within weeks of tuning because of saving a few bucks by buying injectors that arent built by a trusted and quality brand.

Haven't made a decision on what to get...I haven't even really decided whether to go 550cc vs 740cc for what's going to be a pretty mild build. I was just shocked to find that there are these cheap injectors that say that they are NEW JECS-made products. IMHO JECS is a good OEM injector maker, I guess I'm partially asking if someone has actually gotten them and found them to be a quality product actually made by JECS, or if it's something that we should be reporting to eBay as fraud.

Sucks to hear about the Deatschwerks injectors - I always heard good things about Deatschwerks. Bummer

Genuine Nismo 550s are close to $600 BNIB and have the nismo part number engraved on top.

These are $89, JECS "NiSm0" injectors with no part number.

Not the wisest expenditure of funds. You would be better off lighting your car a fire and saving yourself the headache....

Yeah they're definitely not nismo - trying to figure out if they're even JECS.

I think even the JECS are (little) more expensive. But it is still a roll of the dice

Either way, let us know how it turns out whatever choice you make.

I'm definitely not gonna be the guinea pig on this one.

I'll probably wind up with the Tomei ones, possibly Deatschwerks

Any sidefeeds apart from Nismo/Tomei is not worth the cost of entry. But that's just my 0.2cents.

Sidefeeds are pretty damn outdated by any standard.

Outdated? Is there anything really *wrong* with sidefeed? I've never known anyone that had issues with sidefeed stuff.

Does it even make sense to get a whole top feed rail for a mild build (like, T28)?

Outdated =/= issues. For a simple setup they work. You got a few options;

1) Buy a set of Tomei/Nismo BNIB for close to 600
2) Buy a used set for a few hundred which you MUST get flow tested for another 100
3) Buy top feeds.

Its really that simple.

Or....

4) Buy some rebuilt STI 550 for peanuts compared to buying Nismo 740.

Your call.

Yeah, have considered the STI 550's.

What would you say a top feed setup plus injectors would cost? i've seen a wide range of prices but I really don't know anything about what is good / what isn't good. and YES I searched

better to go with the larger injectors... honestly, better to have too much head room with the injector versus not enough. simple build or not, if you ever want to go with a larger turbo, cams, head work etc, the 740cc's will allow for you to add more power versus topping out the 550cc's and having to buy a whole new set.

top feed injectors tend to run a bit cheaper than sidefeeds do... however, you will need to purchase a new fuel rail as well as run new fuel lines from the send and return lines in your engine bay. honestly, the cost of going top feed versus staying side feed is roughly the same.

I got my 600 cc/min sidefeeds from a local company that rebuilds injectors. Really good reputation locally. I just put my injectors in, so I can't give first hand experience, but the PFI injectors are powering most of the local big hp imports.
You may have someone local to you that does similar.

This is one of the PFI listings, a lot less than $600 for sidefeeds:

OK so, talked to a bunch of people about this, and the consensus seems to be that these are most likely knock offs (I'm talking about these that say that they are 'NEW' 'JECS' injectors). Problem is, there's not really any way to know for sure without someone actually buying them (and then most likely winding up with trash and/or trying to get their money back)...and I don't want to be that guinea pig.

Thanks for all the suggestions. The PFI guys definitely seem to know what they're talking about, may be giving them a shot on this build...or just going with my original plan and getting Nismo/Tomei ones.

If you want cheap reliable sidefeeds around 550cc, get the yellow sti injectors. They're 525cc. That said, I recommend going bigger. I thought for sure I'd have room to grow with these but I'm at ~88% dc at 290whp.

If you want to go big for cheap, looks like PFI has some rebuilt 800 cc/min sidefeeds

Should just point out that the Nissan and Subaru side-feed injector connectors are slightly different.

You can modify the two to work together, but I think the Nissan connector will no longer lock to the Subaru injector. It will just slide on and off.

The better solution is to grab the Subaru connectors as well and repin them to your Nissan engine harness. Or splice the Subaru connectors in. Or use patch harnesses.
