I am contemplating adding EGR to a gasoline 4 stroke vehicle that presently has none. The engine is a 1999 Toyota 5vz fe 3.4L V6 in a 4Runner. Some installations of this engine had EGR, mine did not.

There are many reasons for EGR, my purpose of the EGR would be to reduce vacuum caused by the intake under partial throttle by adding air absent of oxygen post the MAF sensor. This should keep from messing with the air fuel ratio. The engine was designed for a supercharger so I assume the stock instrumentation should be sufficient to react to the addition of EGR without going out of range.

I dont believe the stock EGR system from other chassis would bolt on due to interferences, so this would be a custom EGR system. I was thinking cooled EGR collected further back in the exhaust post cats.

Thoughts?
