I really need a straight answer on weither or not you can port a 6-port S5 motor. Within the next month I will be pulling and rebuilding my motor. I really cant seem to get a straight answer on if this motor can be ported.



I would like just an extra 10-25 hp, mild porting. nothing crazy

Why don't you read some of the topics in this section? This has been brought up many times.

Here's your straight answer - YES! https://www.nopistons.com/forums/pub...#>/biggrin.png

My answers run in circles.



But like all of the above said yes you can port these motors.

my motor is a ported S5 6 port with turbo intermediate and rotor housings, among other things.

I have and just become more confused on the topic.



this will be a very low cost rebuild, and i am unsure if porting will affect longevity. I drive the car about 100-150 miles a day and just would like some direction on what I should do when I have the motor apart.
