Seems like it would be easier to plug the injector ports in the head, modify the intake manifold for port fuel injection, and get some custom pistons and a custom ECU tune made up.
This is somewhat of the approach I was going with the exception I was going to try to run the FSI and a secondary injection system as well. For the amount amount of work that's needed to fit a 3.2 head it seems to me that those cycles could be spent better elsewhere. If fsi/secondary fueling doesn't pan out I was curious if something could be done with the mk4 cam setup.I had a custom intake manifold made, left the injectors in the head and am running standalone. Problem with the custom tune is that the 3.6 exhaust cam and adjuster is like the mk5 r32 with different vvt range. You may be able to use a mk4 cam and gear but I haven't tried. Otherwise it could be made to work.
Back from the dead.. Please post an update!I did "3.6 fsi head on 3.2 block" over 2 years ago. This is not rocket science. You does not need big name company to do that. It bolts right on. The only issue are some extra holes to deal with.
Now I'm working on R30 with 3.6 head. The big advantage of the head is the port size ... it flows way better than 3.2
