Go to a salvage yard and offer the person who owns it money for the parts you need, try to get a good deal. What i did was I went to a yard in my city that my uncle had needed parts for. I saw a probe gt with 2 holes in the block, thus I asked the owner how much for just the turbo, he said that I could have anything that I needed for the conversion for 350 that includes turbo, ecu, intake manifold, wiring harness, vacuum setup, intercooler piping, intercooler, knock sensor, turbo manifold, downpipe, and everything on the intake like injectors, but I would recommend that you get new ones. and keep all the bolts. The fun part about the conversion is that you learn alot more about these cars. Plus the gt is heavier than the dx not much more than the lx, thought. But the drawback about the whole thing is that the block is different in some ways, so try and get a good block if possible.
