Engine Swap & CAL smog?
Hi,
Do I have to get 3.4L engine and computer from California emission vihecle?
I am in Ohio now, but my 4runner is from California and planning to go back to California so I want to make sure my truck pass CAL smog check.
I found nice 3.4L V6 engine and auto trans from 97 4runner. I am planning to buy computer to match the engine from the yotota dealer.
Engine is all same 50states and only computer is different?
Please share your knowledge.
Thanks

Toyota did not start putting cal or fed ECU's in the trucks until 1999, so on your 1997 anything will work from 1995.5 to 1998 as long as you stick to 4x4 and what type of transmission you are running. So auto trans= auto ecu and manual trans=manual ecu.

Another difference between early California and 49 state 3.4 engines is the EGR system. California has it and other states may not. I bought my 3.4 engine in Oregon and it does not have the EGR system. I believe Toyota got rid of it in later Tacomas and 4Runners, just not sure what year.

1. You must have all emissions related devices/components from the donor vehicle and they cannot be tampered with.
2. Smog referees are subjective and other than the sniffer test, each one has their own criteria for passing a vehicle.
3. There are some codes that govern vehicles with engine swaps, and referees use these plus "guidelines" in their decisions.
I'm going to contact my local referee and ask about this. I just did a top to bottom rebuild on my engine and will have it put together tommorrow, so if the ref says I need the EGR I can do it before dropping the engine in my truck. The only mod to the engine would be to drill & tap the port for the EGR fitting (the boss is already there) and buy the EGR components. As far as the ECU is concerned, I've only found one part number for it so there should be no problems with adding the EGR system.
If anyone reading this from California has a 49 state engine in their truck and got it to pass, maybe they can comment?

I've been researching this quite a bit and what I've found is:
1. You must have all emissions related devices/components from the donor vehicle and they cannot be tampered with.
2. Smog referees are subjective and other than the sniffer test, each one has their own criteria for passing a vehicle.
3. There are some codes that govern vehicles with engine swaps, and referees use these plus "guidelines" in their decisions.

Can you share with me how did it go?
