I've been saving for an ITR swap, but there is a guy near me with a B18C1 swap (minus ECU). He wants my D16Z6 to put back in his car to sell it. My engine has 157,000 miles. He'll take mine out, and put his in for $3500. Motor comes with skunk2 intake manny too! Engine has 35K miles on it

What would you do?
