ok guys i have been searching and googling for hours w/ no luck. i need some info(pics) on what i can remove from my 97 ka. i found pics of s13 ka's and whatnot but no obd2 s14. basically the two small lines from the TB and intake pipe(plasic part) where do i run those to? and another small vac line by the fire wall coming from the lower part of intake mani? and the 3-way electric thing(egr related i belive) do i need it?

rele need to get the car running info would be great.

You can remove everything including EGR and EVAP which is all the stuff that sits on top of the intake manifold. Just make sure you plug any open vacuum nipples once you are done. I'm assuming you will have the intake manifold off so you can also remove the Evap canister control valce that works your evap which sits in between the runners. Here is a diagram of the OBD2 emissions.

thanks,

2 questions now. the vac port on the throttle body, and on the plastic intake part. do they need to go anywhere? from my research they both run back to egr solenoid. so i could cap them both.

then take FPR vac from the back(of intake mani) directly. and PCV/brake booster too.

correct?

Keep the line that connects to the intake for your IAC valve, then you will have the line for FPR and for Brake Booster. Other than that you can cap the other ones off.
