A.I.R. and E.G.R. help please
A.I.R. and E.G.R. help please I'm going to be buying my pacesetter longtubes pretty soon and was wondering if it's ok to delete the air and egr. I will have the engine out so i though if i did delete them now would be the best time. I really want the clean look and would like to delete them, but i have heard that deleting the egr will cause detonation issues. I have a 1993 lt1 so it's the speed density style.I know the air is no problem because i'm not running cats, I just dont wanna screw anything up, and you cant buy the headers with only egr. I am also doing a cam swap (228/235 LE cam), and will have cai, 24lb injectors, and a pcmforless tune. Info is greatly appreciated, thanks!!
i deleted my a.i.r. with out any issues, definatly make sparkplugs easier, the only PITA part was removing the metal tube that runs under the motor and connects the two sides, i left that in there, also i had a hell of a time finding a m22x1.5 drain plug to plug the two a.i.r. ports in the pacesetter headers, i ended up jb quick'ing in two m20 drain plugs to cap off the holes for now.
Ok, im going to buy race pacesetter longtubes, so they wont have air or egr holes. What i want to know is will the engine run right if it has no egr. I'v heard they will have detonation issues, is it true? I will have it programmed and a bigger cam, i'v heard this helps. The lt4 dident have egr because of it's cam and the cam i will be using is bigger than the hotcam the lt4 had.
You'll be fine without the EGR, especially if your having it tuned afterwards. You may throw a check engine light before you get it tuned but thats just because it's looking for it and its not there. You can do a quick search on the EGR delete if your still concerned about it...lots of people delete it.
