In the process of m112 swapping my 01 cobra and am strongly debating taking the time to port the blower/plenum and possibly fill the silencer holes. I'm just now starting to really look into this so any advice/pointers are greatly appreciated (especially first hand experience). The car will get whippled later down the road so with that in mind, I'm really not looking to pay a couple hundred for a port job. The car is rarely driven at that. Also, I want the blower to scream as much as possible. The more i look the more i realize neither POSI or Steig seal the "silencer ports". Is it even worth it (leaning towards no). I've seen people JB Weld the silencer holes shut but something about JB Weld scared me. Would if be possibly to weld them shut and grind them down smooth for clearance without warping the casing? What is this "stripped rotors" I'm seeing? What's it do? What're the advantages? Again, any advice helps and if you don't have anything helpful to say, don't bother cluttering the thread please.
