I got it of a guy that was going to put it in his RS but then went with a early WRX engine for the same reason you just mentioned. I didn't know that. but anyway its going into the vortex and will get stripped to suit by the AuSubaru loom stripper. Yes i have the ECU, key and ignition barrel, but not sure about the transponder ECM as i don't know what it looks like, hopefully it is.

So those wires, if i use the ECU it came with i don't have to play with them but if i use a V5/6 Sti ECU then i do? did i get this right

Ok i'll look for your posts for the info

Any info about the pipes?
Thx
