k-series motors are hondas future, get used to it.
the swap wil be expensive but it will probobly be very popular in hte future just like civics w/ b-series motors are now and it will cause the price to drop dramatically in about 6-7 years
the swap shouldnt be any harder than any other k-series swap into the new chasis
BTW: you could try to peice a swap together (might be a little eaiser) the k24 also come in a CR-V which has been out longer htan the TSX, and any RSX/SI tranny will bolt to it, and you can use the axels from the si and comp too, just watch out for that whole imobilization thing.
