Emissions Question

stipster · 10-14-2009, 06:40 PM

I have a few Q's about what I will need to do for my 5.7l Vortec swap into my 97 chev s10 that has the 2.2l in it

Do v8's run two O2 sensors on the manifolds one on each side? and wat all exactly else am i going to need to do other then egr valve and all that crap, i think thats mainly what I have left to figure out, other then finish putting the motor 2gethor and installing it in the truck

Should prolly have mentioned that the v8 is from a 99 gmc yukon

You'll need to get the PCM wiring schematic & determine if it will be looking for 2 O2 sensor inputs....you may also need cat efficiency monitors....not sure!?

aight, now normally the O2 sensors are on the manifolds right? bc if i remember i dont believe the manifolds had them, i unno i just need to figure it out b4 next yr when i need to get my actual emissions done

i just looked at it and noticed that i forgot b4 but the drivers side manifold had a pipe that went from the manifold to the intake, now will that be required? as ill be using headers ?

Prolly for the EGR valve.

Anything 96 and newer is an OBDII vehicle and has pre and post cat O2 sensors.

alright cool, now for this pipe do i need to keep it? bc if i do im gonna need to weld a bung onto the manifold in order to do so

No precat on a '97..however there are 4 O2's..one in each downpipe, one before and one after the cat.

well i checked with the local parts store and from what they are saying im only gonna need a total of 2 O2 sensors, 1 b4 and 1 after the cat

Well if you're going through all the trouble of a V8 swap I think we are all assuming that you are going to run a true dual setup with 2 cats. I think you are thinking about this too hard, it's really not hard at all. Are you making the harness or is someplace like CPW doing it?

its the original engine harness for the motor
