Has anyone managed to swap a timing cover with serpentine belt system from the early 90's minivans? I have a surplus 3.1 engine with this timing cover and would love to make it work.

Are you looking at doing this solely for having an idler/tensioner pulley?

I may be wrong. I cant tell what heads you have. Or if it had a distributor. But I think the timing cover would not be the biggest issue here.
The intake from a 2.8 Fiero will only work on a 3.1/3.4 with cast iron heads. 3.1s with throttle body injection had cast heads. Or most that I had seen.
Later model 3.1 used multiport like used on Luminas and looked very close to the late 2.8s. That I'm aware, All the aluminum head van engines were distributor less ignition with different intake port design. I have never seen an aluminum head GM 60 degree engine(2.8,3.1,3.4)that would accept a Fiero intake manifold.

I would be doing this to get the tensioner as well as the advantage of the one serpentine belt system.

Yes it has the cast iron heads.

Just another option for a tensioner is you can look up the user dodgerunner, he made a nice tensioner for the 2.8's. I have one.

Other than A/C equipped Fieros (which all have an additional V-belt), is there a Fiero 2.8 that doesn't have a "one serpentine belt system"?

And as mentioned, Dodgerunner sells a 2.8 belt tensioner that is absolutely first class.

I'm taking that you want to use this engine but with the Fiero 2.8 water pump, Alternator brackets?
Then I think you are OK. [URL=https://www.ebay.com/i/253176346435?chn=ps.] will need to round up bolts. I think the ones on that engine are going to be different lengths.

This is likely going to require a decklid notch!!

Has anybody made this work??

You may've answered your own question as to why possibly no one's previously done this!

Is there a reason in the vehicles that this assembly was originally used that the alternator was held up so high?

"Is there a reason in the vehicles that this assembly was originally used that the alternator was held up so high?"

In the early 90's minivans there was plenty of room to mount the alternator up high. That being said it is directly above the valve cover so it can't be lowered very much.


What about a smaller modern alternator?? Some of these newer cars have smaller alternators on them.

I could easily reduce energy consumption with LED headlights and running lights.
