You can either believe the crap you did read on wikipedia or think for yourself.
Truth is America is the only place in the world where you get that engine in an S13/S14 chassis, and not the only place where Z31 NA was sold. Seeing how turbo CA/SR need frequent maintenance, they would just have massively failed in the US, which would be much worse than having more power than the bigger GT model from the same seller.
