donz_sr20rt104

hows it going people ive got an sr20 non turbo vvt, and theres alot of things i need help with. theres a hose running from the intake pipe connected to a T shaped line connection. and 1 line goes to the the side of the rocker cover and one goes underneath the fuel rail(atleast thats were i think its going). anybod have and ideas what its for? maybe a vaccume line???? added a pic just for a better idea of what I'm talking about

iv already chucked a sr20de in it, having trouble pulling up on the original brakes and got heaps of free play in my steering but can't be bothered finding or fixing the problem so id rather just chuck in a different suspension setup. thanks for help to mate, seen some clean rona's on that site.

hey does anyone kno much about rt104 corona's, having some troubles looking for parts and upgrades if anyone has some info on what brake upgrades i can chuck on feel free to let me know please

iv got a rt104 corona with a s14 running gear, need some advice as to what brake upgrade id need.
