3.1 minivan timing cover and serpentine belt
(Technical Discussion & Questions - by carguy8t8, started: 11-15-2018, last post: 2018-12-09 03:21:32 CET)
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.[This message has been edited by carguy8t8 (edited 11-15-2018).]

(Technical Discussion & Questions - by fierofool, started: 08-30-2020, last post: 2020-09-02 20:09:42 CEST)
I've just had a stock 3.1 engine installed in my 86. The engine is rated at 140 HP, just like the Fiero 2.8. By all injector size calculators, it should be able to run on the Fiero injectors. I have had the injectors from my old 2.8 refurbished and had a failure on one of them upon startup. ...
