I'm no honda guy but I am about to pick up a 91 crx si for $200. The body is in great shape (just got painted black). I'm going to michigan to pick it up, in about 2 weeks. The motor has a rod hanging out of the block. So it needs a new motor. How much money do you think it will cost me to put a new motor in it. Also is it very hard to come by the factory motor. THanks
