Putting a 1990 b230ft in 86 760 couple of questions

[dougw2007]

My 86 760 b230ft has gone bad so I found a nice b230ft at pick and pull. It had 138k on the clock and every indication under the hood was that was real mileage. I took the head off at the yard and the bores head valves etc all look good.
What I would like to find out is are there any specific issues I should be aware of like.

Flywheel I assume is different, the 90 was an automatic but had the sensor mounted at the top of bellhousing and mine is in the side of the block. So I can take the fly wheel off mine and put it on new motor? Any locating pins?

The motor mounts? I took them and they are nice big ones and look a lot nicer then my little puk ones. I grabbed everything off the crossmember.

I have the exhaust manifold off the 90 and it is different then mine. It has bars connecting each port and looks more curvy. I all ready have a newer garret turbo for the car, and some one all ready grabbed the turbo off the 90, so can I, or should I use the newer manifold with the garret turbo? And are these things interchangeable? I do have an extra Mitsubishi turbo around here somewhere and it's not as nice as the garret, but would anyone recommend me using that? Any big advantage over the garret?

Also the intake manifold is nice and clean and I would use it but it has a cold start valve in it. Use it or not?

I don't know any difference yet on the sensors maybe someone could help me out on that.

Biggest concern is flywheel and crank position sensor, don't won't to screw that up, or discover I screwed it up, after installing the engine.

One more thing was the seats in this car( black leather both power) were so nice I could not leave them. I have them and wonder do they bolt into the 86 760? Have not had a chance to really inspect them yet.

Thanks for the help. Doug
