after we rebuilt/ported my brother's n/a s5 motor i felt alot more power compared to a stock port.. porting is better hands down...my car "stock port" was fast but i couldnt get too much more power out of it because there were not many more mods i could do ((( see sig for proof in slllllllllow 1/4 mile time))).i should have dissasembled and ported and rebuilt while i was there.... but now im a turbo man so up up UP THE BOOST and i get more power... well as soon as i get my lazy ass to work on the car i can up the boost.
simply put...... "PORTING RULEZ" lol plus it sounds awesome!
