Alright, here is my problem. So i have 5L short block on its way next week so i can start building my Hybrid. The euro heads i have are at the engine machine shop in limbo due to the new springs seats(new style) will not fit on my euro heads (old style) so they will need to be machined.... joy.

then today my shop buddy had a friend drop off this motor form an 85 928s and told him "find something to do with it". i has been in his garage for 8 years on that cool engine stand.

so whats a man to do? i plan on doing a new ignition/fuel computer system ala Tecgt or MS. if i get that 32v motor what else would i need to physically mount the thing? can i use my OB crossmember?

Ducman. Looks like a nice score. Those exh. manifolds sure look perty.

I have an S4 crossmember you can have, but you will not need it. You can use your early cross member. You will just need the two motor mount plates along with a pair of later style engine mounts. I bought the plates and motor mounts from Roger. You may have to drill a hole to accommodate the motor mount detent if your cross member does not already have the second set of holes (apparently some do). I have also heard of some folks grinding down the detent on the motor mount, but this did not sound like a good idea to me. To facilitate installation of the motor, I JB welded the mounting plates to the cross member. I would have welded them if I owned a welding set-up.

Install that motor complete! Use it as is with Porkens chips in the brains, or convert to MS.

ya i dont have an ECU for a pork chip :-( so MS is the route i would go. still waiting to see what i can haggle for this one. my end go is get at DR twin screw and it seems that a 32v for power add ons is much better then a 16v.... ugh at least im sure i can find a buyer for the heads, valve parts, euro cams, cam boxes etc...

Complications and changes of plans make for a LONG project. When you start talking about MS, I start wondering how many years you are willing to wait before its a driver. Why not get it running asap, and fiddle for as long as you want on the "next" engine?

Ducman82

That's my plan right now. Build this next motor I'm the stand. :-). Then drop her in

I have the ECUs and harnesses available from an '85. Like danglerb said, is it really worth it to turn your car into a 3-year project where you don't get to drive it at all? Not to mention the headaches that may come afterwards. That's not to say that MS or other aftermarket systems cannot work great, but you are going to spend a load of hours learning and tuning or a lot of $$ paying someone else.

Don't get caught up in "awesome project syndrome" for a great driver like yours. It would be different if you were restoring a car or this was a second 928 project.

Fixed it for you.

If you are going to MS, all you would need to do is get a flywheel with the 60-2 timing ring. Everything else on that motor is fine. I wonder if we could save money and get some sort of multi-unit discount for everyone that wants to MS their 32V.

So are you saying you can get that motor for not too much? Or its free?

BC

I would get a later cross member as the early ones do not have the proper flat where the newer engine mounts go. Technically its "possible" with the early cross member, but much much easier to just use a later one.

Lizard928

Actually MS should be able to use the 100-1 toothed ring.
But an S4 flywheel with 60-2 would be better.

Ducman82

ya i have been thinking about what to do..... this motor is not free but i should be able to pick it up cheap. i have been sitting for 8-10 years so a new TB and seals would be in the works. clean it up, a little paint and i think i will be good. how hard is it to add a 85 harness and computer?

What about those 16V EuroS heads?

Slap those on top of your shortblock.

Put her in and have a driver. (Fast one at that!)

Then look for a second car to put the 32 valve engine in.

Ducman82

thats also an idea dan. right now i just need to hear back on this 32v, and also see if the machine shop will be able to get the heads machined for the spring seats. so many choices. but i am starting to like the 32v idea. i just need to compile a list of parts i will need to do the swap.

will i need a bellhousing with sensor hole as well?

Okay......the 85 32V as it sits will make about the same HP as your 5.0L euro....the 5.0L euro will drop into your car with minimal issues and can be ran by your existing computers or CIS with minimal adjustments...

My take...sell the 5.0 32V and run the Euro 5.0L...... Converting to MS or something to run the 32V is just too many headaches.....

Trust me, having a sweet project 928 that doesn't run, but still costs $$$ is NO FUN...BTDT......its all about having a running 928 that does what it was intended to do......49 hours and counting on my 928 Estate....hard to argue with those results!

Ducman82

that is very true ice. the big factor will be what i can pic that engine up for. thanks for the input

and id totally forgot to check that black bag on the Driverside of engine. looks like that might be the harness!
