I got a Spectre shorty carb hat (you could use the full height one as well), and 4" aluminum tubing/angles with silicone elbows/connectors from ebay. I moved my vapor recovery bottle behind the left bumper with a mount from a 94-96 (extended wires, and hoses) then put a cone filter in an aluminum box in the left front corner. I made the box from a sheet of aluminum,and pop-riveted it together. Make sure the bottle is far enough forward that it does not hit the wheelhouse extension. I also needed a spacer from a TBI car to lift the hat far enough to clear the injector tower (may not be needed with the full height one), and make a port for the hose to the valve cover. I drilled a hole for the IAT sensor to the bottom on the side nearest the wire. I also had to make a threaded post to attach the carb hat. I used a threaded rod, bent it to shape, and cut it to length. I have a cardboard template for the box. The box needed small legs to clear the wiring on the wheelhouse. I put a piece of door seal on the top to seal against the hood.
Mine runs straight front and turns across in front of the alternator, then to the box. I do have electric fans on the car, so I have lots of room for the intake. It will be tight against the coolant hose unless you run it in its original path. You would have to redesign my air box to run it in its original path, and the washer tank may be in the way. As with any custom mod, it is a little trial and error. I will try to take pics and post them.
Some people will say to use a Caddy hat, but they are difficult to get to fit, and have an oval intake that is also difficult to make work. I have tried one, and when I took it off, the nut froze to the threaded post, and I had to cut it off. I now use anti seize on the threads. Most have used sewer pipe, but over time it shrinks, and distorts at the hat junction. You could use the sewer pipe instead of aluminum tubing with the Spectre hat for a little cheaper install.
