does anyone know if 93 has a specific EGR system...i have heard that all later years used a new type of system. i don't have my EGR system anymore and was wondering if a later years system would serve the same functionality.

 

and if anybody has or knows someone who has these parts....lemme know. thanks

 

My parts book shows different numbers for 93 than the other years.

 

All years use the same basic EGR valve design, and the same location on the intake manifold. The "differences" on the 93 compared to other years is the way the EGR and AIR plumbing for the passenger side of the exhaust are combined. Its still the same EGR valve.

There are supposedly different part numbers for the EGR valves used on different years, and possibly even special "low back pressure" valves that were used in a recall for EGR flow problems on the OBD-II cars.

And Shoebox has a lot of part #'s on his website:

I compiled this list some time ago. The part numbers are still good.

EGR p/n info

1993 autos use 17113381
1993 6 speed use 17113373

All 1994s use 17113381

1995-1997 6 speed use 17113381
1995 auto w/federal emissions (NA5) use 17113381
1995 auto w/California emission (NB6) use 17113382

1996-1997 autos use 17113382

 

i have a six speed so does that mean that i can't use the auto EGR system...it seems like that one would be the most common type throughout the years. has anyone ever tried to use a later year egr system for a 93? i was just wondering if it would work so i wouldn't have to look for the special 93 part #'s.

 

i just think it is gonna be a nightmare trying to find a 93 egr setup in a junkyard.

Setup? It's only a couple of parts. I might have a valve somewhere. I probably threw away the tube. I'm sure parts out of a different year will work fine though.

 

The only thing that is really different between the years is the valve as listed above.

 

oh..well i have the egr valve...but nothing else is different?

 

The plumbing for the air line for the passenger side of the exhaust combines with the EGR connection behind the intake manifold on the 93's. The 94-97's are not hooked up like that. Are you looking for a replacement plumbing setup, in addition to the EGR valve?

 

yeah...all i need is the plumbing...i already have the egr valve and solenoid. i just need the tubing for each header.

 

I had to look this up (thanks a lot, Fred ), since I was under the impression that all years piping for the EGR was the same. The oddball 1993 appears to utilize part of the AIR piping for dual duty (y-pipe) -initially for the AIR system when the car is started and then later for the EGR when cruising (and AIR is not in use). So, if you still have stock exhaust manifolds, you will need this kind of pipe to feed exhaust for the EGR to the intake manifold. If you had later model exhaust manifolds or headers, you could just use the simple, single pipe that the 94-97s use.

I knew the AIR piping was different on the 93s, but did not realize about the EGR. Great to learn something new today.

 

are you talking about the pipe like on your website...?
