I am trying to get my B16 CRX to pass emissions and have a question about catalytic converters. My best guess is that my cat is shot but when I replace it I want to go high flow. I dont want to have to buy a stock one just to pass then replace it right away so I was wondering do the high flow ones still help with emissions control? If so how well? Also, anyone know what the numbers are supposed to look like for a properly running 1st gen B16?

My scores;
Test/allowed/actual
CO/15/16.42
HC/1.60/1.44
NOX/2.50/1.34

 

Hasnt anyone taken their B16 through emissions?

 

To me your catalytic converter looks fine. Usually the NOX emissions are high when the cat is cooked. I would suggest a tuneup and try again.

 

Tuneup=?

It has new oil, wires, plugs, rotor & dist cap.

 

i took my b16 to the testing place and it failed..... high NOx still trying to pass it

 

you are running to rich.. do u have any fuel adjustment products installed?

try running 89 octane. burns easier.

 

no i dont have any fuel changes made.....but i will try using 89 octane...thanks
