Here's probably a stupid question, and i would have researched it, except if you type S4 or S5 into the search it says it's too small so i gave up.

My engine is gone (as most of you have told me) and I've found a good deal on an 88NA. My car is an 89NA. So here's the question: If i strip the 88NA to the core, will it work with rest of my 89NA stuff?

 

bump

 

So does this mean that no one knows?

 

can be done, but a major pain in the ***. Need to swap alot of stuff. find a S5 motor, its worth your time

 

Check www.rotaryressurection.com They have a shopping list for S4 motor into S5.

 

Excellent thanks. And i would wait and try to find an S5, but the ones i keep seeing sell for a lot more.
