Im totally new to this stuff so bear with me. I have a 97 civc DX coupe thats totally paid for with 100k miles. I think that it would be more cost efficient to just swap engines when this one craps out but i want my car to be fun to drive now. I want to put coilovers, wheels and tires, sway bars, and better brakes on now to at least improve ride handling. My question is if i get upgrade parts such as exhaust, intake, etc., will they be easily interchangeable with the new engine? Thanks a lot.
