We usually only work on old skool Japanese cars, but my partner John Has been doing a bit of work on a couple of xr4ti's and is pretty knowledgeable with the Ford 2.3 turbo and the German Ford 2.9 in the Scorpio. You can do an almost bolt in 4.0 v6 into the Scorpio using Explorer manifolds and a 4.0 out of the truck or Exploder. Cool choice in cars. Also we have a nice "for parts" Scorpio.
