    I'm putting a non avcs jdm ej205 in my car. and was wondering if i would need to get usdm cams to work with usdm valves or if the jdm cams will work. i know that i will need to get thicker head gaskets because the valves may hit the piston (don't rly know what mm to get though). reason why I'm...

    This is an engine project that was supposed to go into my GC8 (up for sale soon too! Shadowfax - 1997 L EJ20 Swapped ). That will never happen unfortunately, unless someones buys this and my car! This was a standard EJ20 that had a spun main bearing. I took it apart, had it bored out to 92.5...

    Does anyone know if i would be able to put a JDM EJ205 into a 2003 2.5RS Impreza? If so, how would i do it and how much would it cost? I'm not very experienced with this and my Impreza has kinda high mileage. Im not expecting the engine to go soon but I am curious about this swap. Thanks!

    Hi all, After my ‘99 WRX spun a big end bearing I have purchased an EJ207 replacement short block with the intention of bolting my EJ205 heads into them. The engine that came out of it was a supposed reconditioned engine, however I am unsure weather it has been pulled from a forester or a WRX...

  7. Troubleshooting
    Hey guys I'll cut straight to the point . I've got a 99 GC8 WRX that I can't seem to pin down what is causing this issue. It started off with the car not wanting to idle when at operating temperature. When it was cold it would idle fine. But now has developed into the car not wanting to idle...

    Hi everyone, I swapped a JDM EJ205 turbo with AVCS into my 2000 Subaru Impreza outback sport and I've run into an issue. The problem is that after it had been swapped and tuned for a month or two, all of a sudden it started having this issue, when I went to go start it up and let it idle to...

    I had a 5MT swap done recently to my forester 2000 JDM S/tb equivalent to V5/6 GC8 ej20 . Been trying to get the vehicle speed sensor to work without any luck. Current transmission is from a GC8 v4 5MT with the old VSS 2 pin output, i've tried linking the VSS signal pin directly into the ECU and...

    Hi All, Brian from iWire here. We put together a blog post with just about everything needed to swap a WRX into a RS. In our case it was a JDM 2001-2004 EJ205 into a 99 RS. Bucky Lasek allowed us to swap his car so we could create resources for you guys. If you need help with the wiring, we're...
  12. Swaps/conversions
    I've got a MY98 RS Coupe and a 2003 WRX with a good ECU, harness, and transmission. Finding a motor's been the very hard part, as in my area (NW Montana), I've had little to no luck within a reasonable radius finding an engine. I've considered going the JDM route, although all of the different...
