Your other option is to find a replacement JDM (Japanese Domestic Market) used engine that's been imported. Larger centers across the US and Canada sell them. Basically the Japanese government forces their citizens to scrap their cars starting when they become 4 years old. The taxes on older cars is just too high and most people junk them. Many are stripped of their engines, trannies, front clips, etc. and shipped world wide. Usually they only have 35 000 miles or so on them.
Check the automotive trade papers/Auto Trader/Wheels/etc., in larger centers around you. I'm sure you'll find one. Check their pricing, shipping to you, and then find a good independent mechanic to install it. Don't do it at the dealership unless you have very deep pockets. And make sure that you get the same generation engine for your car, as well as the entire engine wiring harness and computer, if possible. That makes it a direct drop in without modifications.
Then again, with some searching you might find a good used motor at a wreckers in your state. Good Luck!
