I'm finally getting my '89 4BD1T back together. My plan is to run it in the Isuzu NPR truck for a while to get some experience with it before pulling it to swap into an FJ62 Landcruiser. I have three turbos that I can install: 1) the original setup which is a non-wastegated, watercooled housing turbo in a non intercooled configuration 2) An older turbo, also from a 4BD1T but has a wastegate but no watercooled housing, also in a non-intercooled configuration, 3) a turbo from a 4BD2T which appears to be exactly the same as 1) except that the turbo outlet is rotated to line up with the intercooler plumbing. I also have the intercooler.
I'm leaning towards 3) but was wondering if there would be any real advantage to using the older turbo with the wastegate. With a little work (breaking loose the rust), it also could be reconfigured to line up with the intercooler plumbing.
Any input would be appreciated.
