Doable. Running, driving, sorted SS/TC goblin should easily fetch $22k, but I want you to keep the goblin.
Having built 18 FFR kits and owned 5 of them, I think building a MK4 is a great project to go from the Goblin to. I sold my MK4 years ago and still miss it very much. I may build another one for myself down the road. My personal advice is don't go the cheap route. You will want to do P/S, P/B and heat/defrost. The coyote is wicked fast. A basic 320 is very quick also. The 427 is a bit much for the street, IMO. I built 2 of them for customers and they could break the wheels loose at 90 in 5th gear. My MK4 had a 430 hp 347 and was great to drive. Just my 2 cents worth.

I think your opinion is worth a LOT more than two cents!Having built 18 FFR kits and owned 5 of them, I think building a MK4 is a great project to go from the Goblin to.

Never heard that about the mustang but I believe it. Not sure how I would go about it.I've always heard that you can build a mustang from all aftermarket parts but I don't know far up that extends into the later models.
If you are going carburetor of aftermarket EFI, it should be pretty simple to source everything, but cost wise it might not make sense.
