trying to improve performance on fc s4 (na),wondering what emission parts can be torn out without any harm to motor.advice would be appreciated,thanx.

 

Removing emissions equipment has essentially nothing to do with performance aside from cat removal. Do not just start ripping things out of the engine bay without reading up on their functions. Most commonly, people remove all of the idle control systems because they decide they must be emissions parts.

2nd gen manuals: http://www.rotaryheads.com/PDF/2nd_gen/

Search 2nd gen tech/new member tech thread titles for "emissions removal" to sift through the available info.

 

If you choose to remove your emissions, keep your BACV... As it is not part of the emissions system at all. That is a common misconception.

 

Does Canada have emissions inspections?
