just bought this 92 integra gs for 50$ pretty conditon no rust on quaters but on the trunk lid. couldnt go wrong for 50$ now i need a engine for this thing but i dont know if i can use 5 spd engine on a auto teg. is everything the same or do i need anything the engine that it has right now loos so clean but it makes loud as nosies and feels realy slow. the kid i bought it off said it when they rebuild the engine they fucked up some how and thats y is all gone. now what i was wondering do i need the whole engine or just get the bottom end or should just get a whole other engine from the junk yard or off someone off this. the car is great conditon and interior is mint. what should i do my friend he will swap the engine if he can keep the one thats in the car right now and rebuild it.
