You can't install in your car an engine that is older than the car. So, you can always put in a newer engine - but not an older engine.

Emissions related if I remember correctly.

When people risk their lives, shouldn't it be for something very important?
Well, it better be.
But what is so important about driving faster than anyone else?
Lots of people go through life doing things badly. Racing's important to men who do it well.
When you're racing, it's life. Anything that happens before or after is just waiting.

Nope. I do remember it from my youth when looking at swapping out engines because of emissions equipment. That was one of the great things about owning an older muscle car - you could always get a better engine. But, you couldn't go backwards.

I suppose it's possible that they are more relaxed on that issue or have exceptions - but I doubt it. It would be too hard to regulate. Think about it, they're not going to allow you to put a '65 engine into a 2006 vehicle.

If I had the time I'd look into the regs...

Depends on the state and this is tied to emissions.

In CA, it is actually a felony to violate the state smog laws. This precludes an older engine/newer car swap unless the car is 1975 or older.

I wish the state was as serious about illegal immigration as it is smog.

Hi,

So far as my research goes, you could actually install this Engine in a '97, '98, or '99 Boxster. There were no changes to the Fuel, Exhaust, or DME Engine Management between these years. I suspect that Porsche produced these Model Years under the same, or re-issued, EPA Cert.

But, beginning in '00, there were substantial changes making the swap both illegal and impractical due to the e-Gas, DME, Exhaust and Fuel System Changes...

Happy Motoring!... Jim'99

That is correct. You must put in the same model year or newer engine due to Federal and State Smog rules.
