So... I started an engine rebuild/overhaul. After clearing every part of the block, I found that the rear rotor housing had warped out of specs in the bottom left corner... That being stated... I found that it would be cheaper to buy a new engine.

I'm running an '86 GXL N/A. And was thinking about swapping a S5 13BTII into my S4 car... I checked the FAQ and it said that there was some debate on the power gains with S5 intake ect. What is the debate?

Also, if I have

Would it just be a plug and play engine swap? Any information would be greatly appreciated thanks all!

Here you go man this should answer most of your questions, there's a guy with a thread on here who did it let me find it.

 

This one talks about going from S5 to S4, and if I have a full S5 wiring harness and an S5 ECU. It wouldn't matter about the plug-ins being different would it?

 

s4 engine harness + s5 engine + s4 throttle bodie + s4 t2 ecu + add some wires + s4 front cover for mechanical omp.

Get it? Just the basic, use search button.
