K. Watanabe's has come recommended by two people whose opinions I value. Plus they were not only the cheapest, but offered the best warranty, 12months/12K miles. A guy just bought a JDM SR20DE from them for $275, $385 with shipping. Usually they run $450 before shipping. Ask for Hector at Watanabe's to get the $275 price on a JDM SR20DE. Sorry don't know what compression that engine was, they likely don't know either. Typical mileage on a JDM is around 30K, but I'd ask.
