usually when someone does a turbo on a b-swapped crx, it requires losing AC (its possible to save it, but it tends to be more expensive).
if you have welding skills, this could be more than doable for $1,000 (the manifold is going to be the part where you run into money issues...if you can make your own manifold, this will work for under a grand).
Here is what i would do:
I would get a blox manifold (usually around $180) and block off the wastegate using a piece of sheet metal.
Then i would grab a used dsm turbo and sidemount intercooler (can usually be had for around $350, sometimes less)
Grab some DSM injectors off ebay (under $100). And you can get a greddy knock off BOV (for temp use...the diaphrams break pretty quickly).
Finally youve got piping...most muffler shops can do this for under $400 (will require shopping around....can be a lot cheaper if you can weld yourself).
The blox manifold should fit without replacing the radiator, but if you do need to replace it, you can get a del sol radiator (will require fabbing mounting brackets).
Then there's tuning. Tuning will always kill you if you cant do it yourself.
Theres my little piece of advice.
