Default SR20DET injector quetion

I'm a newbie in the knowledge of injector stuff.
From searching, I'm guessing the SR20DET injectors from a nissan
will fit the my01 gc8. Will you have to modify anything or is this plug and play?

Thanks!

if they do fit, the connectors will most likely have to be replaced which is pretty simple if you just cut the wires and add solderless connectors or something similar. but the only person i know that's used nissan injectors had a 98 RS which used side feed injectors as opposed to the top feed that the 99-01 RS's use.

Like KillerTHC, I believe I remember those injectors being side-feed, so they won't just drop in.

Thanks guys!

Basically the only injectors that are plug and play are the ones from rc engineering?

Nope, the RC Engineering ones need to have plugs spliced into the harness to plug in. Not a big deal, but not quite PnP.

all you need to do for the RC ones is cut the wires, strip em, add a connector. not really a big deal.

I have a set of 320 SR20DET injectors and they look more like the wrx injectors.

Which RS are you talking about? Are you talking about all the RS's made or just certain years? If certain years, what year(s)?

I'm assuming you mean Imprezha, my01 GC8 Impreza but you know people will just take your post and run with it in another post. Just want to be sure exactly where u r coming from. Thanks!

98 and 99 RS's use side feed, so lots of injectors out there. SR20 ones are an option, I sued the GReddy ones for a SR20/Eclipse (550cc units) in my car. Be advised these are low impedance and as such need some sort of aftermarket ecu to run it

2000 and up are top fed, so the Sti new age injector will work. These are high impedance units, so a stock ecu and something like a SAFC will work fine.

Other option is the RC..which are bored out Lucas injectors Wouldn't be my choice (*I prefer Denso's), but people out there use them

Or you can also fit a 98-99 fuel rail, do the rail mod,t hen fit the injectors

so the new 535 STI top feed injectors will work.

does anyone have part numbers for injectors that will work in the 2000> and then part numbers that will for the 99<

I want to clarify that only the MY98 2.5RS has side feed injectors. Granted, my sample size of MY99 2.5RS cars is only three (3), but I had a very good look at each of them, including two that had the Vishnu TEC-II PEMS conversions which are clearly side-feed injectors, and there is plenty of stuff in the archives that mention this if anyone took the time to do a search.

Just didn't want some poor MY99 owner shell out $$$ to buy injectors that won't fit...

Please just don't tell me that SR20DET 440cc injectors will not work for a 2.2ltr OBS because they are 'low impedance' and as such need some sort of aftermarket ecu to run it. I already have planned to use my Apex-i SAFC to run them. Only the Greddy ones used for a SR20/Eclipse (550cc units) are low impedance right? *Hands shaking*

The injectors are coming in the mail and I have NO plans on getting an aftermarket ECU. I just can't afford it right now.

Imprezha,
I'm sorry if I seem like I'm hi-jacking your thread but we REALLY need an injector FAQ of some sort made up. This injector confusion has been coming up for years which was why I stayed with my puny stock injectors in the first place (which worked fine btw ).

The questions I see that are constantly arising are:

1) What year Imprezas are top feed and which are side feed,

2) What are the upgrades for side feed injectors,

3) What are the upgrades for top feed injectors,

4) What is the limit that the ECU will handle injector wise in CC's?

5) What is the limit that the ECU and a fuel controller will handle injector wise in CC's?

Kevin, dont worry if the injectors you get are low impedence you can get a resistor pack from www.carmodifications.com for $60 (just call and ask).

Z1, are you saying that the new age sti injectors will fit into the ej25 manifold and fuel rail? Will the connectors as well?

1. 98 only ej25 are side feed.
99-2002 ej25 are top feed


I will most likely end up getting a set from RC eng. Low price + decent flow.

I just ordered the 440 RC injectors from Tom. Are they not good as the sti injectors. I would like to know if the sti injectors will fit or not on my01 rs.

STi injectors WILL NOT FIT...they are th esame configuration as the WRX and will not fit the manifold or fuel rails.

Just to clear up some errors I posted:

1. the 98 and earlier cars were high impedance, side fed. You can use the SR20DET, or several aftermarket versions (550 's are readily available) for these models.

2. 99 and newer cars are high impdance top fed, much more limited choices out there. Personally, I would not mess with ballasts, etc., but I like things uncomplicated. Your choices are very limited while retaining a stock ecu, or LINK, etc. Gof roan Electromotive, and the choices are much more plentiful (ie you can use either high or low impedance injectors, teh TEC doesn;t care which, just tell it).

3. WRX units do not fit on 99-2001 cars, as the rails are different. I have not yet tried to fit an "02 WRX rail to a 99-'01 yet.

4. I see no reason why a 98 rail (thus allowing you to use the SR20 injectors, or the aftermarket alternatives for them) would not physically fit the 99-01 car. I ahve not tried it myself yet though, just estimating for now.

5. The DSM injectors are low impedance, and won't work without an aftermarket ecu, or ballast adapters.

6. I can check on the SR20 impedance first thing in the AM...I am now thinking they might be high, but will know for sure in teh AM, and if so, correct myself!

Default Question

Is it customary for you to not get o-rings when you recieve brand new injectors? I finally took my injectors out the box today and notice they do not have o-rings on them nor did they come with any. Maybe it's assumed you can just swap your old o-rings from your stock injectors on to them but it just seems kind of odd to me. Thanks!

Are these the injectors that you bought through Ebay? If so, I would send them out to RCE for cleaning and testing. As part of this they will put new o-rings on the injectors. I wouldn't even think about putting in the injectors without having them cleaned and tested first, Kevin. Call RCE and talk to them. It's pretty straightforward and it's what I did when I bought the 370cc SR20DET injectors that I used.

Yes Steve I purchased them off of Ebay. Sending them out isn't a bad idea and I wasn't even thinking about that since they are new. I had not too long ago sent my stock XT6 injectors out to RC Engineering to have them cleaned. They did an excellent job and the results showed. The only problem is that they took my stock o-rings off of all 6 of my injectors and didn't replace them. So I had to order all new o-rings for the XT6 and wait another week. It wouldn't have been so bad if I didn't send them a letter specifically saying I wanted new o-rings on all of my injectors. They did replace the 'top' o-rings though (the ones not in between the injectors and the block). Everyone has a story don't they?
