Ok, i currently own a 91 integra RS and from what i know it is a B18A-1. I am looking to get a new engine in February and was wondering what engines i should think abuot and get your opinions. I was personally thinking a GS-R. I live in Canada and i believe it will cost me roughly 2 grand. Also i was wondering if i get a new engine what other parts will i have to replace. i.e. Exhaust

Thanks for the help
