Thanks, I actually have a standard heat shield, might dig it up and chuck it on. Nice point on the fuel reg lines too.
It runs really good, smooth engine with nice solid pull. The injectors came from the same car as the ECU. doesn't seem to run rich though I haven't had it officially checked at this stage.
As for the skid, not a hell of alot I can do with the open-diff. I had a locker in there a few years back but she got thrashed and almost got me into trouble a few times.
