The first motor I got for my sol was a b18c1 gsr. I bought it online from some dude in Canada. The bastard sent me a blown motor and skipped town. I paid 3500 bucks. I had to replace the bottom end. I was already out the 3500 so I figured what the hell. I took out a loan and went to Ferman Acura and picked up a USDM c5 block. It cost 2500. So yea, I spent about 6k on motor in parts alone - not to mention cost for other things that come with it + labor for rebuild. I feel your pain but it all comes together in the end.
