im in the process of rebuilding my s5 non turbo motor. i took the manifolds off and just got confused as to all the lines. it made my brain hurt so im going to start after the weekend. i want my ports to work so i am going to keep the air pump. how can i simplify all those lines? i live in florida so no emissions and am going to be getin a rb header.

im sure this has been brought up too many times and ive read countless threads saying to search. i probly missed one. if you have a answer or can find a thread please let me know.

and yes ive searched

 

ja you don't need a header for n/a unless the motor is modded[ported, etc.] you can use a downpipe and pre-silencer [rb has them mazdatrix too] I think there is a thread on fc3s.org on block off stuff and what to keep and not to run 6ports. If i get time I'll look.
