how much power are you shooting for? cuz in the long run, i think the K20A2 swap would give you the best results... or possibly the K24 swap but i'm not too sure about the details on that... but with the K20A2 swap you get a 6 speed tranmission and you get 200 hp which is quite a big jump from the 127 hp from the D17Y8... you might want to wait for the price to come down but i really think that would be better than either getting an older civic or putting a turbo onto the D17Y8... then you could always turbo the K20 later for even more power
