But it should still help the engine and definitely would be open to do a top swap in the future. I mean I've been saving up to keep putting money into this car. Got bc racing coilovers, replaced old exhaust pipe , got high flow cat with flowmaster exhaust new rims and tires, front and rear strut bars, new aftermarket headlights and taillights, CAI, just trying to go down the list. Thought headers would be a next great step.

Look at the modifications in my sig if you want to stay NA and still pass smog.

I have the front plog as long as other modifications for an NA and the car is much more spirited than its stock form. My brother had the plog when he was top swapped. Headers are not carb legal in California other than I believe the TOG's.

After the turbo though then comes the fact that a 4k-5k transmission is inevitable. The Z3 turbo is looking like my new goal, and learning some tuning basics. Rollercoaster ride tbh lol.

I am in California in the same location as you and a turbo is not legal. You would want to go the top swap route. You can find the newer style w-bodies at the salvage yard for parts. Check them out as you can on occasion find a supercharged engine. This is what my brother did when he top swapped his 03 that passes smog. It was nice to drive before he sold it. I thought about it but never did and probably won't. Mine is just a daily driver these days.
