Mazda B2600 G54B

What are the differences, other than EFI and turbo, to the G54B in my truck ('87 model) and the Starion/Conquest G54B? I'm looking at going that route and want the lowdown on what's necessary for the conversion. Does the Starion/Conquest use the same head as the truck? Basically, will the turbo manifold from it bolt on to the existing head? If not, will the turbo head fit on the truck's block? Are the bottom end internals the same for both? Things like that.

It's the same engine.

Before I did this swap I'd want to make sure I wasn't getting in over my head, as I know for a fact that there are a lot of differences between 2200 FI and 2200 FI turbo motors. I say that by way of comparison. The biggest thing is the turbo motor uses lower compression pistons to offset the boost and if that is the case you wouldn't know unless you took the head off to verify those facts. I'm pretty sure the turbo motor will have to have an external oil feed for the turbo and your motor may not have those passages drilled in the block. My .02.
