(Question) e30 with California legal m54b30 swap?

[Narsiyousif]

Hi everyone,
I am new to the E30 engine swap but I have been reading all the information about it the problem is I live in California! I don't want to do an illegal swap (i know I can pass it smog with $$ but I don't want do that)
is it possible to do an M54b30 LEGAL swap in California
1- Would the stock headers fit?
2- The engine needs to be taken off an e46 ONLYor I can use the X5/E39?
3-The check engine light and the cluster I was thinking of swapping the (e46/e39/x5) cluster into the e30 dash (i can do that) but would that make it easier or will interfere with other stuff? less harness modification?
4-What is the best option for manual transmission?
I have a 1991 318i (sedan) (m42)
Thank you

I'm going to reply, but since I don't live in Kalifornia,
I'm just talkin' hearsay from other boards.

Rumor has it that you should pick a vehicle similar to yours
(an E46) that's newer, then implement all of its features.

In our case, that means you'll have to use the manifolds with cats.
Which, I don't think fit into an E30. They hit the inner fender. I think.

I am hoping that others will now chime in....

Live in kali with a m54 swap and its pretty much impossible, you would have to seriously modify the car to accept the cats in the headers, same goes for the S54.

Thank you so much TobyB / Motheye99 for the reply now it is clear that m54 can not be put in E30 legally
