I'll second what jerryl said... unless you purchased one of the kits made specifically for the hotair cars like the spearco kit (of which there are no longer any being produced), then its not going to be a simple matter of bolting a few things together. It will probably involve at a minimum reclocking the turbo, fabricating an adapter to go into the intake, and fabricating the piping going from turbo to IC and from IC to intake. Also, you'll probably have to fabricate some way to mount the IC. Unless you're good with a welder and have a decent garage (or know someone who is/does) it might be beyond your abilities.
I don't want to discourage you, I know how frustrating it can be when you decide to do something difficult and all you hear is people telling you not to, but its not a simple matter of bolting a few things together. If you have your heart set on it, use the search function. Use advanced search and narrow it down to only look int he hot-air forum. There a lot of guys who have made their own intercooler setups over the years, check those out to get some ideas of the different ways it can be done. The options as far as turbo location, intake used, IC pipe routing and IC location are limited only by your abilities, your wallet, and your dedication.
From what i've gathered over the years reading about different methods of adding an IC to hotair cars, the conclusion most seem to come to is that unless you come across a good deal on a used spearco kit (which has its own problems as well) the best option to intercool a hotair car is to convert to the 86/87 setup. Not only does this generally end up being cheaper/easier in the end, but you end up using factory engineered parts (which may or may not be better than what you can make yourself, depending on abilities) but also enables you to take advantage of the MUCH larger aftermarket support for the 86/87 cars if you want to upgrade down the road (better headers, downpipes, intakes, pre-engineered IC upgrades, larger turbos, etc.) rather than having to modify aftermarket parts or create them yourself to fit your custom setup.
there are a lot of options to consider, and since none of them are particularly cheap, it bears repeating that your best friend is the search function... before you drop a lot of cash on something, do a lot of reading on what options are out there, what the pros/cons of each are, and and see what others have already done (better to learn from their succeses/mistakes).
Let us know what you end up doing and how it works out!!
