Im doing a heads/cam/headers install on my 97 TA. I will be deleting the cats and would also like to get rid of the EGR and AIR. What do i need to plug up the stuff it hooks up to? i am having my computer reprogrammed at Fastchips and told them to delete the air, egr, and rear O2's. any help would be greatly appreciated.

I purchased my block off plates from here.

 

GM also made a block off plate for the LT4 cars that works on the LT1. It's quite a bit less than those billet pieces that no one will ever see.

 

how about the AIR? how do i plug that up? also, what parts other than those billet pieces can I go with? thanks

 

Its pretty easy to make up block off plates.Get a 1/8"thick piece of aluminum.

 

For the AIR blockoff, you'll need two M18 plugs for the holes left in the manifolds/headers, and a 5/8" vacuum cap to plug the hole left in the intake ducting. You'll also need programming to clear the SES light that will follow.

Do you plan on passing the sniffer with !AIR and !EGR? Not in NJ I hope...

 

heh well i got a buddy....and also a year till i have to be inspected. I am going hooker long tubes, so i dont need the manifold caps. anyone know what part numbers are for the plates to block off the EGR rather than those billet pieces? thanks
