I wish we could stick to English...
"Zenki" refers to 86-88 Series 4's, "Kouki" refers to 89-91 Series 5's. They actually produce 6.6psi and 8.3psi peak boost respectively, which drops to those numbers above at redline. The difference is because the S5 uses electronic boost control to raise boost. You have an S5.
The centre housings, compressor and turbine wheel are identical on both. They have different exhaust housings and manifolds. The S4 uses a common manifold and the S5 used a divided manifold.
