2.7 and emmsisions

[Reynard38]

Talking to my engine guy today. Need to know from people whom are running 2.7's... what cam are you running and are still able to pass a state emmisions test?

[Reynard38]

OK. Anybody here have a 2.7 that gets past emmisions testing?

Mine passed CA smog no problem just after building the 2.7 with a 284/272 cam. Original Cat with 280k on still did the job. I actually had better readings compared to the old stock engine.
Alpina used the same duration cam in their 2.7 so why not. Did use an RD K27chip used in their similar spec. engine.

I would not worry about it.

Hope this helps.

Thanks. I just didn't want to build something that I could not get by big brother.

Wouldn't your car be exempt from emissions next year? My very mild 2.7iS (88 super eta with i head and ancillaries) had no issues passing emissions.

I think GA is going back 25 years on emmisions testing. If it was exempt that would open up a lot of possibilities!

I just checked the GA Clean Air Site. for 1987 you have to test 1982 and newer cars, so it is a 25 year lookback.

Eugh. That sucks. There's options out there if you do fail though.... ;)

Alpina did not use a shrick 284/272 cam, the intake side was around 268-272
