I am working with a tired D16Y7 with 300k miles, I have a friend that wants to sell me his old motor from his 91 CRX (D16A6??) I know about the obd I and obd II problem, but he claims I can bolt up my intake manifold to that head and put it in with no problem and still use my wiring harness. So before I drive 3 hours to get this motor, I want to know if its going to work or not. Hopefully someone can help because this car is slow and wont climb hills only in 1st gear. I hope someone has the answer for me

Thanks
