on the b16a or b16b would i have to move my engine mounts

 

nope i don't think so they came stock with that engine in japan so it should drop rite in. you will need to get a mount kit to clear the hood. the jdm hood curves up in the middle and the usdm curves down.

 

Just go to:
www.hcpengineering.com or,
www.hasport.com.
Read up the info on both of the sites, and also check out
http://www.hybrid.honda-perf.org/. check out the 4th Gen part of the site. There is just too much info about the swap to cover it here. After you check these sites out, then post back here if you still have questions.
