Well I got the new engine and the throttle body has a bit of damage to it. So I was checking it over and realised that theres 2 vac lines on the old one that do not exist on the new one (the two on top closest to the firewall). Now I'm curious if I should just block these off with some caps or what? Should I try to move over the entire system the lines are hooked up to? I'm also wondering if the JDM throttle sensor would need to be moved over as well. On to the exhaust manifold, the old one has some rusting on it, so, again, I want to put my old one on it. The problem is that the new engine doesn't have that metal pipe that runs out the drivers side of the exhaust. I'm assuming I should just bolt/wled a patch over the opening in my exhaust?
