you can do this swap only if your car is an Si!!!

if it is..you use the wiring harness from the crx and put it on the 97 motor. you get a rpm activated switch from MSD and hook that up to your v-tec. You use the crx distributor and tranny complete intake manifold.
There is a few other little things you have to do and your set..my friend has a 97ex head on a 94Si/ex block in his crx.
If you got any more questions PM me.
