Yeah this little detail we missed caused much sadness after the newly installed block wouldnt start! We got it to start temporarily by hooking the fuel pump directly on to the battery (NOT RECOMMENDED! ;D) Anyway, we (Reuben and I) took pictures of its location and the wiring required. Apparently, the fuel controller varies the pump speed to 33% 66% and 100% depending on load etc whereas on the single turbo it pumps full stick all the time which doesn't worry me, less delay getting fuel to the engine is not a bad thing in my books hence doing the split fuel rail.:
Location:
It is behind this panel:
and looks like this:
The diagram/schematic to go with it, click to enlarge
Idea is, rewire (at the controller) pin5 to pin6 and pin10 to pin7 (two black wires, a red and white. The l/g wire back to the ECU becomes redundant)
After that is done, run a wire from the ecu pin A21 (l/green) to the driver's side relay. (Reuben, can you remember if this was the top or bottom relay? Must look at wiring diag's again)

Interesting indeed. I was just going to say chris has appeared to have no problems, but then i remembered he rebuilt the engine, used a V7 shortie, with thick HG's. God knows what the compression ratio is, but it ain't 9:1 in that car
I don't really know much about compression but I actually used genuine Subaru head gaskets which were actually thicker than the old ones. Also, the pistons in the new block are a completely different shape (ie have dip-like things in them whereas the EJ20TT block didn't to the same extent) Hope that makes sense... must get a compression test one day... anyone in Auckland have compression gear?
