I have a 1994 honda integra Zx 1.6 Dual Carb, the engine is blown and i need to swap it. Would a 1.6 DOHC Vtec engine be an easy swap? or would it require alot of modifications...

Also what about a 1.8 Vtec engine from a 1995 Integra? Would that be an easy swap or would it require many modifications.

Thanks
