I bought a '92 voyager a little over a year ago and have put close to 80k miles on it. I looked for a 3.3 because I wanted pushrods (no timing belt or smoking mitsubishi valve seals/guides)
I rebuilt the A604 with kevlar clutches, new steels and a shift kit from trans go and it changed the vans personality. I actually get better gas mileage now and I don't know if that is due to a tighter converter or the new shift points, but I average close to 24MPG and drive like an idiot. The van will chirp going into second if I floor it on dry pavement and I haven't touched the engine yet.
I think this was probably the best $500 vehicle I ever purchased and keep meaning to upload some pictures of it with my custom interior (Dakota bench seat FTW) one of these days.
