It can be done BUT even though the car is free the money and time its going to take it would be worth it to me to just pull the head on the car have a valve job done, put a timing belt on it and sell it.. Take that money and buy something alittle newer and start there... I've bought 90 body style integras (needing work) for $500.00.. So to recap fix the free car, sell it, buy a newer body style integra and start there.. Or if you just love the 87 or the idea of it call hasport they make a kit for the 1st gen CRX and integras to do a B series swap...
