I have had a 93 Honda Prelude SI for bout 6 years now since I got my learners permit and love the car. However do to high mileage and other such intangibles the I shed my timing belt. After being towed to the shop and looked at my father and the mechanic were discussing the problem, the guy gave him a price on fixing the timing belt ($250-ish) and warned him that their was a possibilty of valve or other engine damage. The car of course has an H23A in it and my father recently told me my uncle who is into repairing salvaged cars has a H22A4 from a 97+ lude that was beyond repair but the engine was in excellent shape (I was very excited about the possibility of this engine in my car) and he would give it to us very cheap sub-$1000. However I have no clue what it would intel to do this swap. Could some help me and let me know how difficult it would be and what it would take do this. Thanks everyone!@
