Engine Swap

My old 91 4door rs integra has about 158k miles on it and im planing to swap the engine sometime soon. I think the engine is an A-someting and im just asking what other honda engines would fit my car. Im not looking for the best there is like type R or even GSR (im cheap). what are some engines that are "good" that would fit (prelude,accord,integra)?

You have a B18A1 I would swap in a B20Z or B20B but the B20Z is a better choice. They are both direct bolt in swaps, you just need to use your stock ntake manifold and exhaust manifold from your B18A1. The pr4 ecu you have will work with the B20's also. The B20 swap is the easiest swap there is.
