Im just curious... what are the things on the type s that actually add 40 hp more. Plz list all if possible , thanks

 

pistons (higher compresion)
bottom end (fully balanced for higher rpms)
different ecu
different head
vtec on exhaust
bigger vavles
6 speed for better gearing ratio
different header
different intake manifold
better cams with higher lift and longer duration
shorter shifter
there might be others but i dont know. if i am wrong on any of this please tell me

 

oh yea rollor rocker arms.
different springs and retainers.

 

**** thats a lot of stuff..

 

header is the same... i think..
