Hi! Newbie here. I'm wondering what type of engine do I really have. I swapped a 4g63 DOHC engine...a 7 bolter. They're saying that this is an RVR engine. I know indeed that this is a 7 bolter. Problem is I don't know what this engine equates to there in the US? I have relatives there that can ship or carry parts I need over that's why I need to know what brands/names/terms to look for. Thanks!
