Also considering a A/C delete cause im never going to recharge that thing.
^ This is the 1g factory vacuum/emissions diagram.
^ This is how to eliminate the emissions system. Cap off all the ports on the throttle body (you can use one for your boost gauge or you T into the Fuel pressure line). Block off your EGR and then you can remove pretty much everything else.
The only thing wrong with this diagram is that you should not T into the BOV line for your MBC. Use the nipple on the J-pipe/compressor housing instead.
also is there any info on a 1g a/c delete I only found 2g guides
I have a repair manual that tells how to remove a/c components for repair and replace, so just fallow that and leave it out, would there be something else I need to do so this does not interfere with my car working properly, as far as lines and wires, or is it as simple and pull it all out.
The biggest gain from removing the EGR is removing the intake manifold and throttle body to CLEAN the build up out of them. The other big gain is achieved if you have a leaking valve which would then remove a boost/vacuum leak.
As for the pressurizing the gas tank, that will only happen if you block off the breather line from the tank.
Removing the AC won't give you anything except maybe a hair of a miniature pony. The only time it causes load is when the clutch on the AC compressor is engaged (when the AC is on). If you have a bad compressor then that's a different story.
I did remove mine and it was pretty easy. I would highly recommend to take it to a shop to get the refrigerant evacuated and recycled. If you choose to ignore that, either wear a protective APR (Air Purifying Respirator) with chemical filters and a face shield. If you don't have those, then hold your breath and get out of the area until the vapors are ventilated out.
If at any point it was filled with a dye then use a rag or end up like me.
The white on the rag is frost.
That is another reason why you should get the system evacuated and recycled.
