California vs Federal Emissions Identification

[Trailer Park Ninja]

Hello Crew,

Kinda two part question here.

I have a engine that was pulled from a '95 LS400. I'm trying to identify if this engine is CA or Federal emissions equipped.

I did find info on up to '94 there was a secondary air pump under the intake for CA emissions but cannot find much on '95 and higher 1UZ.

The donor car that this was pulled from had two ECUs. One installed and the other in the trunk rolling around. When I searched the ECU part numbers they are both for '95 (one CA the other federal). Unfortunately I cannot recall which was installed nor the decal under the hood...


Any information that can be shared on stripping just the CA emissions items to make it Federal that can be shared would be awesome. The county I live in will need to have this project vehicle pass visual and running smog testing. So if this is a CA equipped engine I'd love get down to as basic emissions as possible and use the federal ECU.

If this were a Honda motorcycle (my main area of experience), I would mention that the 4th-8th characters in the vehicle's 17-digit VIN identify the market and variation for which the vehicle had been intended to be first sold. For example, 1990's era 49-state bikes have a 0 in the 8th position and California-spec bikes have a 1 in the 8th position. And Canadian bikes have a 2, Australian ones have a U...

In any case, I would not be the least surprised if Toyota and Lexus VINs also included that level of market differentiation within the VDS portion of those VINs. But, you said "donor", which suggests the vehicle (with the VIN on it) is long gone, but maybe you have a record of it somewhere?

I don't know if the emissions type would be reflected in the engine number (but probably not). Good luck.

Ciao,

Hey JZH,

I tried to decipher the VIN with no real luck. Maybe with a paid VIN check you get more?

Perhaps with '95 and up there was an additional cat??? Just seems like there would be more emissions added and controlled by the ECU if they had a CA and federal ECU...

Thank you
