You can swap the block and not have any issues. The heads are a different story. What you would have to do is swap your current throttle body onto the 98's EJ22 intake manifold, and swap over your current intake manifold wiring harness.

This should allow you to run you stock IACV and sensors, I said "should", I haven't done it. In theory it should work, but I might have missed something.

The easiest swap is to use your stock phase II EJ22 intake manifold and swap in an EJ251 longblock with it's corresponding exhaust manifold (your ex. manifold is single port).
