Need help before doing swap please

[umfogotmyname2111]

I had a quick question I was helping someone could anwser for me. I have a 88 CRX Si with the original d16 in it and I am planning on real soon either throwing a DOHC ZC in it or a D15b vtec in and I was wondering if the headers of my original car would fit on either or those or if I would have to buy some new headers. If someone could please help I would appreciate it. Thanks.

D15B yea; DOHC ZC i would think not, but i am not sure about that.

I would figure they would not fit as well.

they should be reasonably close, being D-series, the DOHC though, im not sure on, i think the flange pattern is the same, but the length and angle of the collector may be off.

thanks guys....i guess i'll just have to take mine off and check it when i go to check on the motors just to make sure

your header will definetly fit the D15.
as far as the ZC it will fit the flange pattern
but the exhaust ports are bigger, so you would have to
port your header to make it match up to the head.
