So I took the insurance off my car and built a shed around it for a little protection from the elements.Now for the hard part.I'm going to remove the engine and turbo to rebuild both and replace some hard to reach electrical components.When i'm done I hope to get another 23 years out of it (yeah right).So my query is;does anyone have any good tips or maybe things I should do to make the job easier?I'm only talking about removal and replacing the engine not the rebuild part.And is it easier to remove from the top or bottom.Any suggestions will be greatly appreciated.Thanks guys.

(if it makes any difference it's a '80 931)

I don't know... I have pulled and placed my engine 3 times now. The first time, it took about 12 hours to get it out, and another 10 to go back in. The last time, I did the whole thing in a day, 6 hours to pull it, 8 to place and re-assemble. Getting the #$!!#$ thing in there is the harder part, as it has to be canted JUST SO in order to line up with the motor mounts.

If you pull the intakes and head off first (The easy way) make sure you get new gaskets and o-rings wherever you removed an old one. If you leave the head and intakes on (HARD way) be prepared to do emergency 1st aid when the engine starts eating your hand for lunch in the tight spots.

In my experience out the top, isn't bad as long as you get everything out of the way. Remove the hood, you still need to drop the cross member,and taking the head off first, out the top is alot easier. Now if you want to leave it together drop the suspensions completely. Disconnect the electrics and joses. exhaust and the likes. ANd brong the whole thing out the bottom on a jack. I have done it both way both are about the same amount of work.
But the easiest is when the front end is off the car and you can take it straight out. Yeah this is the easiest.
Take Your time
Clean everything
You would of done well to pressure wash everything prior to sticking it into the shed. Makes dealing with dirty parts alittle nicer.
Have fun, Make sure you have a book or two. ANd if you can get a friend to give you a hand during the hard arts your doing well. I do al my engine pulls alone. I have gotten real good at it.

Most important Have Fun!

I pulled the engine out of my 931 last month and it is still on a stand, waiting on a replacement head. With the exception of removing the hood, I've done everything alone.

Removing all the "required" engine bay components, dropping the front suspension and pulling back the transmission & torque tube took me about 4-6 hours. I had "issues" with the motor mounts, but once I overcame that, unhooking the last of the engine bay and hydraulic plumbing, and actually pulling the motor only took about another hour.

I suggest you pull the entire motor out the top, head, manifolds and turbo still attached. Here's why: To remove the head, you have to remove the exhaust manifold. To remove the exhaust manifold, you have to remove the turbo (or everything except the turbo-to-block mount). If you've ever removed/replaced the turbo with it in the car, you'll understand perfectly. Good luck getting to the manifold bolts with everything in-place.

Bottom line is that the turbo has to come just about completely off. It is just as easy to leave things as they are and remove the entire engine, then remove things where you have some working room.

cmxxxi is making good sence as usual ..I dont have a turbo
so never worked on one .See on the na its easier..if its best to leave it together it still shouldnt be to hard to remove..htough maybe you should recruit another person for the install . I still say for the removal take as much off as you can..When I spun a rod bearing a 2 ago I dropped the block out the bottom all that was left was the block ,crank, oil pump..pan was off
rods were out.. Installing is gonna be where you encounter the alien.

So on a non-turbo is it best to go out the bottom. I figured to put the car up on ramps and take out the cross memeber, disconnect the tie rods and lower the engine out the bottom.

I agree with no front end on it is easy. I took my 944 motor out that way. Cut the entire front section between the lights out. Of course that section was junk anyway.... but way fun and easy

I do not have an engine hoist so that is why I am thinking out the bottom for the 1980 NA engine.

So are you saying I have to remove the tranny and torque tube to remove the engine?This will be more work than I thought.

Yep,no need to slide back the tranny or tube, just remember to drop the steering rack, and the cross member or the oil pan will hang up.

Perhaps it is possible to remove the thing as they suggest, all I can say is good luck doing it. These photos will give you an indication of how far the engine has to be separated from the drive tube (tube all the way to the rear in the photos). You be the judge as to whether you think you can safely shoe-horn the whole thing in and out in the space provided. I suspect you'll be hard pressed to keep the assembly level while pulling the mass of the motor on and off the shaft.

Let us know how things turn out.
