Default RS to WRX conversion (Update)


Well its been a while since I last posted anything on the conversion, and alot has happened since then.

Last weekend Bill and Chris came up and we spent both Saturday and Sunday tearing apart my RS. We completely Gutted the car. Now you don't have to go that far when doing the conversion, We just wanted to get a total understanding how where everything went (wire wise).

So Saturday was basically taking everything apart, and removing the 2.5L engine. Last thing we did before 11pm was put in the Legacy Cross-member.

On Sunday we spent most of the day tracing wires in the WRX harness. Now when they say this is the hardest part of the install....they weren't kidding. Basically we traced where every wire left the Harness, we wanted to see what was easier.....either replacing the RS with the WRX harness, OR integrating the WRX engine and ECU Harness portion with the existing RS harness (Removing the Engine and ECU of the RS). After spending about 4-hours going back and forth.....we decided to modify just the portion that consists with the ECU and engine. Since the rest is still the RS, why change and modify it. Unfortunately since the Bill and Chris had to leave that night, we stopped and started putting the engine in. I installed the JUN Flywheel and ACT Clutch from the RS engine and put it on the EJ20. We then dropped the engine into the car. It took longer then we thought, as the engine JUST fits in the GC8 body. The EJ20 WRX engine is much bigger then the EJ25 RS phase II engine.

That was it for last weekend.

For the past 5 days I have spent installing the rest of engine hardware and exhaust. Everything is mostly bolt-up. The only modification I had to do was with 3 things.
1. Had to trim a portion of the heat shield so that the Rear O2 Sensor can fit (the opening is opposite between the two cars).
2. Had to drill new holes for the by-pass solinoid valve bracket.
3. Needed to mount the Power-steering fluid reservoir.

I also was able to mount a Lower Front brace, and a Front Whiteline Adjustable Swaybar. (As these were meant for the GC8 WRX and wouldn't fit on the RS).

SO now everything is installed in the engine. THere's not much room left in the engine compartment. But everything fits as it should. Only thing left is the wiring harness. (GOD.....it is so easy to say that )

Oh well.......got only one way to go now.

That's about it. If you guys got any questions....feel free to shoot me a message.

Is the WRX engine from a Japanese GC8 WRX? Or is it from a 2002 US Spec GDA WRX?
