cat / def removal legal now??

u could always swap a ls into a non chevy vehicle. the engine just has to be newer model year than the car it was going into and all the emissions equipment had to be in working order with an appropriate ecu for the application

not in california. the rules are;
has to be from the same make/manufacturer.
has to be from the same class of vehicle IE: cant put a big power truck engine in a car.
has to be same year or newer.
has yo have everything from the donner vehicle.
and depending on the ref. has to have all original manufacturer parts (not authorized replacment parts).

but either way, it would be nice to just get fed/epa approved cat parts for $150 instead of the same performance part for $3k in cali

I’ve done several swaps. You can absolutely put an LS in a non GM vehicle. The rules just state it has to be same year or newer and you can’t put a truck engine into a car. SUVs are the loophole for this, allowing you to swap a 4.8, 5.3, 6.0, or 6.2 from Tahoes, yukons, Escalades, etc into cars.

not alk sure about that but i so wish for that.
i would just buy a GM E-rod creat motor and drop it in.

when i did my SOHC motor swap, i got a totaled sport trac and transplanted the whole thing in. it had to be exactly as it came out from that exact year make and model. and the year (i think only year) not only had one evap, it had 2. and i had to have both.
i think it is miss and hit depending on the ref. all refs are taking classes at local community colleges. maybe some things have changed since i checked.

You are correct in that every piece of emissions equipment has to come from the donor vehicle and you car has to pass emissions as if it were the donor vehicle. It used to be very popular to do this with jaguars back in the 80s and 90s. People would swap in TPI 350s (L98s) from Camaros and corvettes. This was also popular in jeeps, FJ40s, etc. the Erod LS engines are neat, but CARB stipulated that those are only eligible to swap into OBD1 (1995 and earlier) vehicles.
