I haven't even had time to even yank off the manifold, but yeah it's that plastic stuff. So you say the returnless 2.5L LIM would be better for flow, but wouldn't the injector be asymmetrically positioned in the port? I've seen some pics of the plastic 3L IM and I noticed that the injector sits in the middle of the port. I wonder how it would affect it if any, since it would be aimed at one port.
Externally the 3L block looks the same guys, so I don't see how they would find out unless I said something.
The last official to look at it (which was a cop, and pulled me over for being guilty by association) was more mystified about this big hole in my engine bay. I had moved my battery in my trunk and he kept trying to say that I had removed some smog device from my car. Then he points to the big red 2ga amp wire and tries to say that I had disconnected my EGR. I was messing up my EGTs and polluting the air he says. Then I get a ticket for having a modified exhaust, I have Borla cat-back exhaust which is "50 state" legal.
