Okay, let me give you some background, Z-owner. My background with cars is mostly 4-bangers, with a couple V8s, an I6, and the SOHC VG. In the cars I've worked on, the engine leaves ample room to work with. The VG30DE occupies a very wide area, owing to having dual overhead camshaft heads, and the TT is even worse, considering the plumbing and turbos. That area all but entirely fills the engine bay in the Z32. Working on it is nowhere near as easy or comfortable as other cars with engines that aren't so massive for their displacement. I tried to work on a Z32 a friend's brother has, but I couldn't get my tiny little hands in there to figure stuff out. I suppose it's different if you're familiar, but it's off-putting if you're not.
I'm gonna firmly suggest you don't take what I say very literally. It's obvious hyperbole to say any work requires pulling the engine. That statement is an exaggeration to stress that the Z32 engine bay has really cramped quarters because its engine is rather wide, because DOHC V-engines are typically very wide.
