if you're looking for the same engine like the one that you have engine it self goes for like 300 to 400 plus labor so about 600 to 700.. now for a swap it would be different.. if your looking for like an h22 vtec engine, engine itself goes for 1500 to 2000 and you still have to get a tranny for it coz your stock tranny wont fit like if you wanna put an lsd probably another 1500 to 2000.. thats only the engine and tranny no labor yet a good swap usually cost 6000 to 7000 depending on the engine and tranny that you want.. if you have the funds i say go for it.. get an h22 plus an lsd tranny.. performance shop usuaslly does it.. hope this helps..
