First of all, I think you need to search a little bit before you ask a question.

1) No, you cannot swap a 420a into the car. The 420a is the non-turbo that came in the 2g's and it would be the most un-worthwhile swap of all, a 1g non-turbo 2.0 would even be better than the 420a. Any swaps into that car would not be worth the cost and effort.

2 & 4) Car-part.com, ebay, dsmtuners.com classifieds. We cannot tell you how much these parts will cost because we don't know how good of a price-shopper you are. It would also depend on alot of other variables like new/used, where you're getting it from, etc. I would estimate soely an intake mani (no sensors or TB) for about $25-50 and a used radiator for $75 or so.

3) I'm pretty sure the heads are not compatible, therefore the swap would not be possible.
