TPI EGR Question
I require some information reguarding the EGR valve on a '88 305 TPI. The engine im working on did not have an egr valve on it and I need to know the restrictor orafice size and/or the GM part number cast on the valve. I have called a dealer and a couple of the parts store in the area and they have all given me different numbers and none of them are on the reference sheet from the egr that was purchased. Any information would be much appreciated.
P.S. The engine has california emissions and will most likely be going back to california so it will need an egr.
