if your engine is shot iam thought i saw some for sale post about a ls swaps being sold. You can get one for like 900 probably less then that. Have some one put it in for you if you dont knw how to yourself. Iam sure alot of people would help you out find a ls motor. There all over the place. Not very much if you think about it. Its a full motor. Your tranny is good water wont effect that at all. Unless you let it sit for every and rust away. These are like 98 motors to not older gens. Ls motors if your not wantting to spend alot for a swap. Just go with that. Lot of help from TR or hondaswap that could help you out with getting a motor in your ls and your worries over.
