For full 01+ swap fuel rail, TB bracket & possibly IAC relocated (some say they don't have hood issues). Hard vac lines also need to be fabed together. I don't have a pic right now of that.
Brazed fuel rail.

All this work was performed my Terry Haines.
If you want to use the 3L oil pan it needs to be modified for 2 tranny points. Otherwise use the 2.5 oil pan and P/U tube. And DO NOT grind off or bend up the support for the P/U tube. I don't have the part # for the correct P/U to be used so the support is retained.
Pulse wheel needs to be changed to 2.5 along with 2.5 timing cover.
And if you don't want to do it that way then your other option is a hybrid. Take all 2.5 components and swap them onto a 3L block. Simple as that right?
