Hi all,

I was wondering what causes the power difference between a Celsior and Crown 1UZ VVTi. From my understanding, the Crown outputs 276 bhp while the Celsior outputs 290.

I've read that the earlier Crown motors had restrictive exhaust manifolds, but apparently that wasn't the case for the VVTi variation.

So, what's responsible?
