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

Flywheel, do you mean flexplate, for an auto? Are both auto?
The 90T is Bosch lh2.4, your car should be Bosch lh2.2.
The sensors have to be swapped, such as temp sensor, maybe the throttle sensor, iac. The old car has a Hall sensor in the diz, the 90 used a cps on the back of the block. So swap the diz.
Manifold; the 90 is supposed to flow better. I don't know about the turbo fitting though. The mitsu is smaller and is supposed to spool faster, which is good for city/normalish driving, not so good for performance.
Intake; prolly doesn't matter.
Motor mounts are better but you need the alu pieces they bolt to on the block.
Seats should bolt in.

"...the 90 was an automatic but had the sensor mounted at the top of bellhousing and mine is in the side of the block."

If you mean the sensor (wiring) shown below, you can ignore it. That was a for Volvo special tool ("Monotester") that's no longer used. But I'm surprised you found it on a B230 block as it was basically a B21 tool (possibly B23 too), or so I've read.



Google Volvo Monotester Sensor for some history on this item.

Copied from the 700/900 FAQs:

"Timing Off; Ring Gear Out of Position. [Tip from John Sargent] If your flywheel has been replaced and you are experiencing timing problems, check the position of the ring gear which determines timing. To check this, remove the starter and position the engine on TDC for number one cylinder. There are 58 holes on the timing ring, with a void of two holes (room for 60 holes, total). The void will be at the bottom of the starter opening if the ring gear is installed properly. See other timing tips in Engine Performance."

In order to avoid problems with the engine swap, maybe you should retain the extraneous components from the 1986 as much as possible.

You said "...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..."

The side of the block??

Where is the distributor on the 86? If it's on the side of the block then you have some serious work to do. I suspect the 86 has a cam driven distributor with a hall sensor inside of it rather than a flywheel sensor. Maybe someone else can comment on the sensor you're seeing on the side of the block.
