I have an 88 crx that has a 91 d16a6 in it. I am going to put a d15 vtec head on it. I believe it is the d15z6 head. Now for the question . What gasket set do I need to get? will the full gasket set from the d15 fit my d16a6? or will I have to mix and match? Also replacing the thermostat and the water pump. I will need to get those for the d16a6 correct? Also anyone know what kind of compression ratio that is going to be around? Thanks for any help. I am a honda noob, but i have fell in love lol.
