#1. It's way too expensive to do & too complicated.
#2. It's much easier to do LS Turbo, B18C/C1 Swap, B16A OBD0 swap & wayyy cheaper.
#3. You will have spent sooo much money on the K swap that you could have put all that money in your car and be smoking plenty of fast cars on the track.
#4. Your LS is highly capable
I say do the b16 swap. Really, for the money, it is much more worth it! I seen a couple vids of hondas rollin with the b16, and they could smoke a porsche, or lambo off the line... It's pretty amazing!
