Default Where to find 440cc Injectors?

Where can I buy 440cc or 550cc high impedence injectors that will fit into a 2001 2.5rs? I called RC enginering and they said at this time they dont have any injectors for me. They would allow me to prototype a set, but the price is still 360 and I would have to splice the injector harness. I was wondering where everyone else are getting their injectors?

I'ld be willing to prototype mine

would sylvia injectors work? I'm sure there are companies that make them for the sylvia's

The Silvia uses a side feed style injector and the GTI-R uses a top feed injector but there are alot of aftermarket companies who make injectors for the Silvia. Doesn't SARD make injectors for everything?

What are all you other rs-t's using? Tomorrow I'll call vishnu and see if they have any ideas.

what about sub injectors? that way you only use the extra fuel when you need it, however I'm not so sure how reliable it would be if it was in constant use.

Why would the 440's from RC not work for you? I talked to Vishnu and they said they use RC 550's in their TEC kits. I have a set of 440's from RC, they are high-impedance and top-feed.

edit: I think the TEC uses low-impedance. But still, I believe you can get high-impedance from RC.

RC does have injectors that will work on the RS? I've asked them that question at least three times and each time they say "no". This is getting very frustrating! Wcbjr and others on here use the RC injectors yet RC says they have none for me. They must not like me.



Wcbjr: Are you the one testing their prototypes? Have you installed them yet? Any fitment problems? Do they plug right in? If yes do you have a part number?

They say they won't work because they are not drop-in injectors... you have to solder on the harness to get them current since they use different plugs ($9 each from RC Eng). I'm not sure, but it could be that the o-rings need to be changed too.

I've got a set sitting in a box, though I will most likely end up using them.

Not only is there a problem with the harnesses, but I believe the injectors are 1/4" taller than the stockers. So you must raise them somehow.

Well I am working on getting STi 565cc injectors. Hopefully at a good price but we will see.

Bill -

Keep in mind that WRX injectors are much different in shape to the RS ones, so the modification it'll take will be pretty extensive.

Andrew at AMR said that the wrx stock injectors drop right in. The only problem is they are low impedence and we have to get resistors ($60) to compensate. The stock wrx injectors are 440cc. Would this mean that the sti 565cc injectors would drop right in and only need the resistor pack?

The stock WRX injectors drop right into what? Last time I looked at them, they were WAY off on size. I'll see if I can borrow one from someone that has swapped them out and fit them into my extra intake manifold and rails... I doubt they'll fit, but it's worth a shot.

I just talked to Andrew and the stock wrx injectors are high impedence and so are the sti's. So we wouldnt need the resistors. They flow 420cc and fit into our fuel rails. I hope you get a chance to check 8complex. I would love to get the sti 565cc's especially if they fit right in.

There seem to be a few different versions out there from what I am finding. Some fit and some don't. Sort of strange don't you think.

8complex,
If you find a set that does not fit let me know, I will try to stay away from those then and hopefully find the right ones.

Well, if I can find one locally, it'll be a stock WRX injector. So anything that drops into the WRX will be in the same group with those. I think I can find one pretty easily... there are two people I can ask that I know have stocker's out, but not sure if they have the stock o-rings on them still.

xephyr here on i-club is using STi 565cc in his 98 RS-T with his own custom made fuel rails.

He sells new ones if you want to order - PM him, his name is Mark Ramirez...

Default RC injectors

RC is a pain to deal with....No matter what info you give them they will still pretend that they are not available....I had their product code and their model # off of a freinds set right off of his RC injectors that he ordered about 6mnths earlier and they still pretended they did not have them available.I ended up buying a set from Andrew at AMR that he had from an RS he had used during developing the LINK system for it. I don't know what the deal is with RC now they used to be cool and real knowledgeable. By the way Vishnu's fuel rail mod comes with RC injectors? Go figure...

I've been having the same problems with RC. They seem very disorganized.
So your the one who got those 440'c from Andrew

On top of that RC wants people to try out their prototype, not sure if it will work, at retail!

I talked to Robert at Forced air tech, and he said they have been using any generation Eagle Talon TURBO 450cc injectors. He said the idle is a little rough, but not enough to have any problems.. I just picked up a set on EBAY for 61 dollars shipped. If you send them to RC Engineering to have them cleaned and blue printed, you can have an awsome set of 450cc injectors for about 140 dollars.

wrx, sti and rs injectors are high impendance (I tested and re tested), the wrx and sti ones will fit with no big issues the My99 2.5 rs imprezas, you just have to play with the o-rings and eliminate the bracket on top of the injector, sti will work as well!, on my00+rs, is a diferent history, the intake manifold is diferent where the injectors sits, and the injectors has an extra extention, I think they will fit, you just have to play with o rings again

DSM injectors are low impenence.

you have to put resistors in to make it them work right.

the actual injectors that will work depends on yoru year car. the DSM will fit 00-01 and the pre 99 ones use a different style.

I'd be willing to sell my stock WRX injectors and stock WRX fuel rails/fuel pressure regulator. You'd need new spray end o-rings for an RS. Both rails have some pipe left on the end, but you'd still have to flair the ends and use hoses/hose clamps. Good time to convert to parallel rails!

There's a pic of the WRX oem rails/FP regulator I just took out... sorta hacked all the pipes up to get them out, but the rails/regulator and injectors are all in perfect shape.
