Hey guys,

I'm new to 914World, but not to 914's. I had a rusty '73 *way* back in the day, and still think about that car.

Turns out a six conversion is recently up for sale nearby and I'm drooling. Allegedly originally a CA car, '76, with a 3.2, with headers into a Dansk 2 in, one out. In other words, the car does not have a cat. converter. I'm wondering if that matters given its age, though I'm pretty sure the 3.2's had cats and maybe even CA 914's.

Are cats common in conversions, or not? Am I going to have trouble at the DMV? If so, is there a way to make it all better? I know the 3.2 had to be turned around to go into the engine bay; can the original 3.2 header pipes (and cat) be turned around to point out the back?

Thanks, any wisdom on the topic would be appreciated!

So, in CA you still have to get renewals on smog every 2 years if the car is 1976 or newer. Like with my 86.5 928. One when I brought it into CA and then every 2 years.

California has gotten super tight on this. It has been hard but now it is really hard. There are NEW GM V8 engines sold for hot rods and such that come with FI and Cats make huge power and pass the sniff test

While this is true for stock cars, this thread is about conversions.

So technically while exempt from *testing* (Not compliance!) if the car is a '75 or earlier, as i mentioned above if you swap a later motor in an earlier car, you have to comply with whatever the rules were for the year of that motor.

So if you have for example a 3.6L from a '95 993 and put it in a '70 914, you still need all the smog equipment that was mandatory for the year 1995.
