Vtec head

if i slap on a b16a head on my b18a, and run an oil line what else will i have to do mechanically to the engine?

i also would need an ecu, would b16a be fine, or b18c?

i’m not looking for an all out racing engine, i’m just looking for some vtec. any help would be appreciated

Do a search for ls/vtec. This has been covered many, many times.

…and gs-r oil and fuel pumps. Please…Please don’t rev past 7500(after new ecu etc) or you will have some serious problems.
