Woah now, Greg.. put your flamethrower down. I'm VERY aware of the JDM issue as it's the primary reason I haven't built a new engine yet and am running at the back of the pack.
I was asking for a clarification on what is actually allowed, since that's exactly how some other people are going to read it when you say you can use any intake manifold from that chassis. The same chassis code was sold all over the world, and that's how I read it. That's why I'm posting and asking questions.
In the case of the 240SX, the FWD SR20DE intake manifold points backwards in relation to the required mounting on an RWD car. There's not enough room (about 2") between the firewall and the back of the engine to plumb an intake through there, especially after you "re-engineer" the ignition system to remove the distributor. All of the important bits are mounted over the tranny in the FWD version, and that's unpossible if you conver to RWD for obvious reasons.
The RWD version of the engine has the dizzy coming out of the side of the head and the intake flows from the other direction, which solves all of those problems.

There was, however, an SR20DE installed in the S13 and S14 chassis (in Japan of course) that could provide a bolt-on intake manifold solution, but you'd still have to re-do the entire ignition system to make it work.
See where I'm going with that? It's easy to come to the conclusion that's what this rule was intended for if you want to lean that way. The issue is stretching the chassis code designations past our shores which is easy to do if you look at it in this context.
Edit.. pics changed to links since they're huge and some clarifications.
