If anybody in the states if thinking about doing an engine swap to a UK celica engine and are concerned about emissions, here are the results.

My 86K mile 1994 6th Gen 173BHP Celica GT just had it's yearly health check (MOT)

@ Fast Idle 2824rpm

CO 0.02% (Max 0.3%)
HC 5ppm (Max 200ppm)
Lambda 1.00 (range 0.97 - 1.03)

@ Natural Idle 850rpm

CO 0.2% (max 0.5%)

Needless to say it passed ....it's a Celica.
