How about this for an RS solution?

I have a customer who is interested in going turbo on his RS. Since there doesn't seem to be any reflash solution here I wonder about just using a WRX ecu? Does anyone have any insight as to how different the WRX ecu is? Suppose I swapped in a WRX MAF and injectors then I suppose I could probably map it to suit the engine...

I'm pretty sure the camshaft and crankshaft position sensor wheels have have different teeth arrangements. The WRX ECU expects to drive coil-on-plug ignition. What year 2.5RS? I think 2004 and newer can be reflashed with Ecuflash using a Drive-By-Wire Tactrix OpenPort cable.

From what I've seen the crank and cam wheels are identical. If not then I suppose they could be swapped over as well since everything fits except those with variable valve timing.
