Did a search and found nothing, so if this is old information, please remove.

I have a 2006 Beta II and was looking for some larger injectors that didn't need a lot of work to fit ... couple people in PR mentioned the WRX injectors. So after some digging I came up with this ...

These are plug and play:
OEM 2002-2005 WRX - 420 cc
JDM STI "pinks" - 550 cc
OEM 2006-2008 WRX - 560 cc
OEM 2007-2008 STI - 560 cc

The ones below are from a 2007 WRX and are a direct replacement. Only need to use the stock Hyundai o-rings top and bottom. The ones shown are the 560cc ones. I'll get them cleaned and flow tested soon and post the results.

WRX injector is on left in top two pictures and on right in the bottom picture.

If that's true, talk about a major hassle reliever for Hyundai people looking to add fuel!

Yes, yes. Do keep us informed!

I know the Beta 1/2 fuel systems are different, however are the injectors the same?

I believe the I and II use the same injectors..As long as the rubber washers both transfer and work,this is an awesome discovery!

Actually, I found a perfect bottom rubber seal. Its from a Bosch L-JETRONIC injector, 1987 Nissan Pulsar. Its the bottom seal.

I'll update with a picture later tonight. Fits perfect, but I have yet to do a long term test. I tried them and the car started and there were no leaks ... pulled a CEL from being to rich, but I knew that was coming.

I also have some 2007 WRX STI "Pinks" coming. They flow 560cc and should also be a direct replacement, with the Hyundai top o-ring and the L-jettronic bottom seal.

wow, this sounds like the perfect option for those looking to go turbo. If that CEL can be cleared somehow, then it could be possible to run turbo without tuning.

Any chance you can pull the mode $02 freeze frame data from the CEL? do you have that resource available?

If I remember it was a P0172 ? To rich condition. I think that was it. The injectors were 420cc, and the stock are 190cc so I don't think the ECU could trim them down ... but this was expected. I was just checking them to see if the sealing leaked. I have an AEM F/IC, but I'm making a P-n-P harness so it wasn't installed at the time. If it was I could have turned them down and would have had no CEL.

Beta II's do not use the same injector as the Beta I's (RD's). Look at the round connectors. Beta I's use "EV1" rectangle style connectors. Beta II's are EV6's or Denso, I can't remember.... If memory serves me right, they are also slightly longer.
The GK's on NewTiburon.com have been using the WRX injectors for years.


The cheapest direct fit injectors for the RD have always been the Ford Racing green top 440's.

And trying to run 40lb injectors with no tuning???? bwahahaha!
