I'm jumping right into a Weber conversion on my '84 Subaru.

 

I am at the stage of removing stuff. I should get rid of the EGR valve, right?

You can, but installing a Weber really has nothing to do with the EGR.

It honestly doesnt matter either way. I ran a weber with the EGR for years until the EGR started to get sticky and affect driving performance. Then i just blocked it off. There is really no power difference and if the car is tuned correctly will run just fine either way.

but there are some benefits to leaving it hooked up, There has been many posts on the board on this topic here is a good one:

I tried hookin up the egr on mine, T'ing off the same line aas the distributor. but it just didn't run as smooth as I like. with it unhooked, it runs great.

I had to have it hooked up to pass a visual, so I screwed a small bolt into the T, and then put the hose back on it. so it's plugged, but looks operational.

with some main jet fine tuning, it still passed the tailpipe test ( with no cat, to boot)

There's No Need to use a "Tee" Nor to Share the Vacuum advance Port with the EGR, because the Weber 32/36 (I assume you're installing that Model) Has Two independent vacuum ports in Front, One (The one that comes Open) is for the Vacuum advance while the another one (The one that comes Blocked with a tiny Screw) is for the EGR.

 

To use it, just unscrew the Blockin' screw and hook the EGR to it.

 

Kind Regards.

I pulled mine off on my ea82, and I've pulled several over the years off different vehicles with no ill effects. Theres no good reason to have one other than emissions and theres lots of reason to take it off. Because they inject inert air into the intake stream, they also reduce power by reducing displacement...this may not be noticable on a 1.8l, but its still there. These motors need all extra power they can get and any gains will be seen at the top end when the EGR is suppose to operate. EGR's inject a lot of soot and carbon into the intake charge which builds on intake runners and valves, wearing various parts and affecting performance. They can also be the source of idle problems when they stick.

 

EGR's are for cooling combustion temps, but its for emissions, not for the safety of the motor. It will run a tiny bit warmer in the chambers, but not enough to affect anything or even register on your temp gauge. People may tell you it will melt the motor, but it willn't.

That's the Reason why I removed all the EGR stuff from my BumbleBeast, plus the New (Third Gen EA82) Heads came factory without EGR pipe.
