Should NON-US motors be allowed in ST?

[Z3_GoCar]

I suggest a US-spec SR20DE with 12:1 compression, .600 cams/springs/retainers, and rods/bolts can make well over 220 ponies at the crank and a boatload of torque all the way up to 8000 RPM. That head casting is as good as the SR20VE one, you'll start with an NX high-port head, and you'll port it for airflow.

You don't need no steenkin' turbo.

I'd listen to Greg, he knows Nissans. Request an alternate intake manifold, and add a crank-fire ignition tied to a custom ecu. If you can get a non-honda at more than 220hp, then you're doing well.
