You keep going on like a broken record. There is no information that you need to know to choose a US engine over a JDM. Recap:
1. The only difference is the intake manifold
2. The cyclone manifold has more low end torque but flows LESS air than a 2g on the top end.
3. The 'stats' are that the JDM has 220hp. It's because of less emissions regulations and tuning. Probably in the ECU, NOT the manifold.
1g is better, aftermarket is better. I hear most of the cyclone manifolds aren't even installed right, since they are a dual runner system.

Also there are clearance issues between the Cyclone manifold and the larger US A/C compressor. Yes you can use it, but not really worth the hassle. Some manifolds will say "Cyclone" on them but not have the dual runner butterfly system. The timing belt upper covers sometimes can be slightly damaged from shipping, also the igniter or coil pack may be damaged. This usually happens in the shipping container on the boat ride from Japan.
