I have been helping a couple guys out with some carb/intake advice today, and decided to copy some of the info here. One of our members is trying to put a Weber on his '86 E16S, and ran into a snag. The adapter doesn't cover the coolant passage on top of the carb flange. I have never used a Weber, but I'm sure it's a great carb. In any case, I doubt the Weber adapter was intended for use on the electronically carbed E16's. That's why the adapter won't work right on them. Seems to me, that the Weber deal was intended for the '82.5 and '83 regular choke carbed E16's. They don't have the coolant holes on the carb mounting base. That is the intake I have always used, and it is the one shown below. This series of pictures, shows the modified '83 intake, opened up with a die grinder, to accept an '85 Nissan [720] Pickup truck carb, from a Z24 engine.
You can see how much bigger the Z24 carb is, compared to the E16's.

This is the Z24's carb gasket, up against the tiny stock E16 carb.

The orange baseplate gasket is from the Z24. The mounting holes were close enough, to oval out, to fit the E16's carb studs.
Here's how the finished product looks.
