I searched but didn't find much... curious to what might happen when you run S4 rotor housings with S5 ecu.... since the spark plug placment is off and timing is diff.. wondered if or what other people have encountered or thought....

It will have no practical effect. It will work just fine.

I'm running a 89 TII engine in my 87 TII and it runs fine.

 

no issues as far as timing difference for better gas milage..or worse milage..... thinking about the effects.. wouldn't it cause a slight decrease in the split timing....just thinking outloud...

 

while it is different, it will run fine......a friends S5 t2 ran fine with a S4 t2 engine....
