ok so around summer time if i have enough money i am wanting to go ahead and swap the engine instead of building the one i have in there right now. i have an 94 integra Rs which means its an LS engine in it...anyways, i am wanting to know what is probably the least expensive swap that in the long run i will be able to produce the most power out of it....now, i really dont want to have to replace my exhaust n intake right off the bat so i woudl want something that they would both bolt up to. i just dont want another LS engine unless its already built. please giev me some idea's.
