Hi going for sva at last

normally all the cars i have doen before have been pre cat engines so no major issues,

this is a 1997 engine though so
can someone confirm the emissions for a cat test on a 1997 engine for sva,

i think im wright in saying all engines after 1995 require a cat???

thanks just need to play around to get as close as poss before sva,

0.3% co at 3000rpm
less than 200 ppm HC
lambda 0.97 to 1.03

0.5% co at idle
less than 200 ppm HC.

It may be initally tested at 0.2 at 3000rpm
and 0.3 at idle

Thanks for the reply

am i wright in saying all engines after 95 need a cat????

thanks all

I think strictly speaking a cat is not mandatory, but in practice you will not be able to pass the emissions standards without one
