Start by looking at pictures of the two throttle bodies (eBay is a good place) and see if they're even remotely similar. If they are, then there's a possibility they will be interchangeable. There is still modifications to do though, since the intake tube is too small for the 2ZR TB, and the opening on the 1KR intake manifold will also be too small. Even if you make it fit, the only benefit you will be improved throttle response. The engine won't be able to flow enough air to take advantage of the larger valve, so there won't be any top end gains.
