EVAP / EGR etc...
EVAP / EGR etc...
Ok I have been reading through threads for a bit now and im just trying to get a few last quesitons answered. Im finally close to putting this beast together...
I am finishing up the intake and I was wondering exactly what MUST be connected to the intake and what can be plugged. Im not worried about a gas smell etc... is the PCV hose a necessity? Can I use a breather instead? I want to get rid of as much of the egr system as possible. Do I need the solenoid connected and stuff? I will be using an aftermarket fuel reg and I noticed a vacuum hose connects to the stock one. Will an after market one such as the standard aeromotive one require that hose? Im not even worried about needing the inside vents to work. I just don't want any of that under there since this will only be a track car or when its too cold for my bike...
Any help would be appreciated. I will continue browsing these threads for answers.

I have cleared all the emissions crap on my car - there is no performance benefit from it, but cleans up the engine bay. Easiest just to list em...
Don't "need":
- PCV on passenger head valve cover, can run a breather and cap TB
- EVAP line , can remove and plug
- EVAP solonoid, can remove and plug
- EGR, can remove and plug using blockoff plates(need two, one small one large for the intake, and a third if you have stock or emissions headers for the driver side header)
- AIR pump, can just disconnect and remove/plug it
Need:
- That fpr vac line must be there, the psi is based on vacuum, and yes the aeromotive has the spot for it
- Opti vac line(if vented Opti)
Some will need to be tuned out depending on your car. OBD1s throw less codes and SES lights. Just a quick list - any questions just ask and I can elaborate.

OK so I attached a few pictures from SHOEBOX's website. Is it ok to remove the following as he has them labeled in the pics:?
Vacuum Check Valve (Is this required?)
PCV and Pipe (do I leave this on there?)
Vacuum Feed & EGR Solenoid (I already have blockoff plates installed)
HVAC vacuum check valve
EVAP canister purge solenoid
(I know the one to FPR needs to stay now...)
I know I should know more of these answers but I don't have all of these parts because I baught a roller and I only want to go and buy the parts that MUST be installed. Im not looking for performance gains, just a good running car.

Vacuum Check Valve (Is this required?) - As long as you are willing to drop the HVAC controls, you don't need it.
PCV and Pipe (do I leave this on there?) - Removing the PCV valve, and the vacuum source that evacuates harmful vapor from the crankcase can lead to oil contamination. A draft tube (circa 1955 SBC), a vacuum pump, or an "eductor" on one of the headers can be sustituted.
Vacuum Feed & EGR Solenoid (I already have blockoff plates installed) - Will need the codes for the missing solenoid and the lack of EGR flow programmed out. Neither helps nor hurts a performance engine.
HVAC vacuum check valve - You already covered this.... same as your first item.
EVAP canister purge solenoid - Will need code for solenoid and vacuum detector switch programmed out. Neither helps nor hurts a performance engine. May be more difficult to tune with the EVAP system functioning.
(I know the one to FPR needs to stay now...) - It is possible to tune for a non-vacuum referenced fuel pressure regulator. I do not have a vacuum compensation line.
