have a d15b7 engine in my 1994 honda civic right now. i also have a d15b vtec engine in my drive way. i am wondering if i can take the parts of the vtec engine and put them on the d15b7. is it compatable. i already purchased a vtec ecu. what all will i need to do. I first planned on swapping the whole engine but after looking at the vtec engine i thonk it will be easier to just convert it seeing that all the wiring and hoses are all cut off the vtec engine

You can convert it, but you will have to drill oil lines and stuff for vtec. It will probably be less complicated to just do a swap. It would be better to spend a little more time and have the motor built right in the car, rather than 2 motors you jacked up trying to switch the parts on.

the only real differences between a base engine and one with vtec are the head & ecm. you could convert or swap here. keep in mind the mechanical items that will require your attention if you decide to convert. these include: head & block condition, machine shop time & costs, head gasket set, timing belt, water pump, swapping of any necessary wiring or accessories, etc. most of these are relavent even if you decide to swap. is there any way for you to locate the engine harness from a vtec car? you will likely need this to determine any wiring differences. i must ask you: why use the d-? for a few bucks more, you could step up to the b18c1, or was cost an issue?
