[drifterx]

i wanna say sorry people for posting this... i hate these Qs
how much HP can i probably get  with these mods on a S13 SOHC
custom catback with N1
Hotshot intake
JW ECu
magnacor wire with +4 plugs
and i dont know what header to get while keeping my cat
should i get a pully? adjustable cam? (and what kind? and are they good and worth the money? how much? and what HP would i expect?)
what else do i need to mod for N/A? (i cant afford pistons and rods yet)
thanks guys
