its designed for bigger motors... It works on the B16 because the B16 has a high redline, so slow spool-up isn't as much of an issue, the B16 also moves a lot of air. It would work OK, but you wouldn't make a lot of power until just before redline. With a smaller turbo, you'd be making good power from say 2700-6500 (or whatever the d16z6 redline is :thinking: ), with a bigger turbo, you'd have lag from idle to ~4.5k, and then a bunch of power from 4.5k-6.5k... just not as usable/pleasant to drive.
