I am going to be putting a DOHC ZC into my 90 Civic. I know you can use a header made for a d-series. But the ports won't line up and you will have to port match the header. I'm not really trying to do that if I can avoid it. Since the engines in the 88-89 Integra are similar to the ZC, can I use a header made for an 88-89 Integra? Will I have to port match it at all? Will it bolt up to my stock exhaust without modification?

 

anyone know?

 

I am pretty sure the stock manifold from the Integra will not fit the zc. It is a 20 minute job to modify a D header to fit... I would just go this route.
