eBay is fine for charge piping and intercooler. That's it. Nothing else.
Source your turbo from Precision, GReddy, Turbonetcis, or even a stock DSM turbo. Wastegate can be any major (see: GOOD) brand, so long as the bolt pattern to your manifold is the same. Manifold, that will be the tricky part. I don't even know what motor sits in that chassis.. I think it's an obscure D series or something. I don't know of anyone that makes a manifold or anything for it, so you may have to have it fabbed. Now that I think about it, charge piping might be a b***h, too... Other than that, any blow off valve will work. Fuel injectors and fuel pump would be another problem. There isn't a lot of aftermarket support for EM2's/7th Gens, so sourcing this stuff is not gonna be fun. Lastly, your tune. I have no clue how you'd tune this thing. Maybe a K-pro, but I don't think it's a K series, so that won't work. Maybe Hondata, if they make a ROM/ECU for it?
