The STOCK RX-7 460CC and 550CC injectors are exactly the same length.

Let me try this again:

You can use any injector you want, as long as the impedance matches, the size matches, it physically fits in the rail and it plugs in.

If one of those things is different, then you will need to make modifications.

Fuel injectors are in a way generic. Whole families of injectors use exactly the same body and connector. Even those that don't can often be easily modified to fit (ie. Ford 1680CC injectors).

Almost all injectors have a part number on the plastic cap. Google that number to find the specs for that injector.

I'm looking for answers along these lines

yes

280sx are plug and play
subarus arent for s4 but are for s5
mitsubishi eclipse turbo plug and play for s4 n/a
mitsubishi lancer plug and play with s4 t2
etc

not
well any injector could work if you cut this throw in resistors here
well it might work in your car you might have to modify the ...
ecu doesnt play a part(it does the ecu has a number on it asessing which series it goes to)

please stop posting this useless information its been gone over plenty now , wanna know what cars work you know like creating a list
looking for answers from the creative people who have tried OTHER VEHICLES INJECTORS to see what OTHER VEHICLES INJECTOR DO WORK

I see. You just don't know enough to know you don't know. I'll leave it to others then to provide the answers that I have already multiple times.

Edit...I'm going to try this one more time.

Any injector will work in your car, as long as:

1. It is of the same physical dimensions
2. It is of the same impedance
3. It is of the same flow rate.
4. The harness connectors match.

You can find all this information by Googling the part number of the injector you are curious about.

The ECU does not know or care what injectors you have connected to it. If the impedance is wrong, that could eventually damage the ECU. But you can plug any injector into the ECU. By plugging in different injectors, you will however effect the amount of fuel delivered to the engine because the ECU doesn't know you have swapped injectors.

So, if you want to know if injectors from a '78 Lancia Stratos will work in your RX-7, just Google the part numbers on those Lancia injectors and then compare the specs to your RX-7 injectors. If they match, then you can use those injectors.

If you have a standalone, you can use any damn injector you feel like.

really useless info not specific to anything this post is about


I'm looking for answers along these lines

yes

280sx are plug and play
subarus arent for s4 but are for s5
mitsubishi eclipse turbo plug and play for s4 n/a
mitsubishi lancer plug and play with s4 t2
etc

note how the models of vehicles that injectors are italicized and say what model they will fit into

now with that in mind try to keep thoughts of calling this place and that place or looking up parts numbers for your self they are unneeded/wanted

Only looking for makes and models from people that have tried plug and play options.

for instance subaru sti has injectors that will fit and properly work with s5 t2
lancer evolution 8 has injectors that fit and work properly in an s4 t2
mitsubishi eclipse turbo has injectors that fit and work properly in an s4 n/a


Not that hard

look alex understood
Ok ok I get it, u wana know if evo injectors work with 87 s4 tii rx7. Well as long as they are the same impedance.....hahhahahahaha jk I get wht ur saying and I've wondered the same thing before. I've seen Chrysler injectors for Sale that were at least 1000cc IIRC. And the other cars that I can think to check would like supra or 240sx

even the jallenator got it
i too looked into this but kept running into an issue..... they were all too damn small. i found plenty of injectors that would physically fit in place of the stock injectors but were always around150-300cc. nothing was ever up to what i needed.

The problem is everyone DOES get what you're asking, but you're not understanding that the information given can be used to find any injector you could ever want.

You started a discussion about denso-style injectors that could be used in place of the OEM injectors, and everyone in the thread gave you a pile of GENERAL information that could be used to find any injectors that could work. Who cares if no one has any SPECIFIC examples of injectors they've tried? There are 2 very simple reasons why hardly anyone will have tried to find another 460cc or 550cc injector that will work:

1) Injector cleaning can restore virtually any of the OEM injectors out there to like-new condition. Having an injector fail completely is rare, so there's little point to buying a brand-new 460cc or 550cc injector at all. Injectors can be serviced for $15-20 a piece.

2) Most people looking for injectors will be wanting something LARGER than stock. I can't think of a single non-rotary, factory vehicle that would have injectors larger than 550cc, yet be cheap enough to warrant buying them AND have the correct shape/size/plug/impedance to be compatible. The piston community often looks to us for cheap injector UPGRADES, as RX7s have some large factory injectors. Here's a thread from a Z forum that shows just that: http://forums.hybridz.org/index.php?...-upgradesswap/

and here is where we shall but heads

i guarantee with 100% confidence that this info helps someone, the idea is to move on from this part and find out the different injectors that DO WORK like the ones ive listed multiple times with different makes and models that are more readily available and or less pricey than the rx7's .

Lets say i was at a junkyard and looking for injectors , with a list of vehicles that would have injectors that plug and play without mods . keep in mind the vehicle should be a newer model so you dont have to rebuild the injectors.

thank you for all the input whether it has been helpful or not, and i assure you aaron your info helped in the begining, but now i know these injectors fit so i dont need info on checking stats, there are millions of different applications for injectors , thousands that share properties , isolate that down to these 300 injectors share the same size impedance and will work properly in your car

and with this i do give up just close the thread its a useless attemp to consilidate information that could be helpful if worded properly

Then you can put one car on your list:
-2003-2005 Mitsubishi Evo 8

Because that is the only car I know of that has 550CC injectors besides the FC/FD.

Our injectors, even the NA 460CC injectors, are much larger then what you would typically find on piston vehicles. Typically, piston engines have 200CC - 350CC injectors.

In high HP 4 cylinder cars, like the WRX, you might find large injectors. A Google search shows that the 2004 WRX STI has 560CC injectors. The problem is that they are side feed.

So there is almost zero chance of finding a suitable injector at the wreckers.

The only car I can think of that has larger injectors are the LPG/LNG Ford Crown Vics/LTDs that have 1680CC injectors. They are white topped and are part number part # 0 280 150 839 at the local Ford dealer.

i think aaron just hit it right on the head there. like i mentioned already and he just did the injectors in all these other cars are too damn small to work!!! and people seem to take the rx7 injectors and put them on their turbo hondas. if ou stand back and look at all the injectors in modern cars the ones out of an rx7 will be high on the list for cc ratings. its just plain and simple dude, there are not that many that are bigger, or will be pnp
