B series

I have a 93 integra anda i'm about to get a job soon. I was planning on buying an exhuast, cai, and headers. I have a B18a in my car now, and i wanted to make sure if i bought parts for that engine, would i still be able to use them if i get a gs-r swap later on?

Its an ls rite? Well if your getting a gsr swap then its gunna be a b series, so yes, the things you listed will fit. Dunno bout the headers though, not sure.

Headers arn't interchangable from engine to engine typically. The exhuast ismade to fit the car chassis. Since of course your chassis doesn't change, the exhaust will work after the swap.

I was pretty sure it would i just wasn't 100% sure and didn't want to be wrong and waste my money.

Yes they will all fit perfectly. I know somebody already answered, but consider this reinforcement to them :)
