Now I want to try even harder to verfiy distributor fitment on a d17 head from the 01-05 cars, as I will have an easier time with the Insight engine sxwap if I can get a d17 to run on obd1 electronics.
Congrats on getting this out to production. It has been quite a ride man. You will see a purchase from me soon.

Any interest in getting a CARB OE number for these?
Em2 d17 obd1 coil on plug
We started the project of a D17A2 conversion to OBD1 and keep the individual coils functioning , here the progress... The patient is an EM2 D17A2 We started working the cam so it can run the distributor. EGR Removal:

I have an f23a1, b20z1, a z6, a y8, and i could likely find an h to play with as well. I've got a smog guy that loves dicking with stuff if I bring the beer, and my area smog ref is open minded. That does only cover the beginning stages, but its a start if you are willing to do hours of paperwork 😃

Luckily the paperwork for an exemption on a personal vehicle is pretty straightforward, so I'll have my personal number engraved on it shortly after I can afford it, lol. I even get to run my s300 legally, though any time I touch the maps I have to go run it on the dyno and get a new calibration code recorded.
So you can prove your car yourself to be carb compliant in Cali? I didnt know this!

Yes, it's a bit time consuming, and you kinda have to see the right smog ref, some are unwilling to certify things modified in certain ways, most don't like forced induction on a car that should be na, but if you can prove that it actually lowers tailpipe emissions over a certain service interval you can get a carb oe number, they usually engrave it on any aftermarket parts, if the ecu has been tuned via chipping they write it on the eeprom, if a demon or s300 is used they will give you a calibration number to label the tune with. By the end it's probably 1500 in fees but better than being at risk of a car crushing should you get caught without carb oe numbers on all your bolt ons or a swapped motor that hasn't been cleared. Lately they will even require a smog ref visit just from the block stamp not being what it should, like a b7 in a 4th gen or a y8 in a 5th gen, or a z6 instead of a b7, and its only going to get worse im sure.
Ah, so that's the gotcha, its dumb expensive. Man, if only they made it cheaper to achieve, you'd have a ton of folks a) be more willing to perform vehicle modifications in cali, b) performing vehicle modifications correctly while still controlling emissions to a standard.
If I had control of CARB, I'd make allowances for vehicle modifications with combustion engines that met an even playing field standard for the engines themselves, kinda like the on-highway HD diesel engine manufacturers play. All noxious gasses from an HD diesel engine are regulated to a Brake Horsepower/Hour limit. This allows noxious emissions to scale based on horsepower rating.
If it was like this for passenger cars, you could have a path to prove "Yeah I turbo'd my civic, and it makes 450whp, and emits the same noxious emissions under full power as a brand new Charger Scat Pack, but because it weights half as much, emits half as much overall CO2 per mile."
So long as you could prove you were trying to do right and control harmful emissions to your BHP/H limit, I personally don't see any harm in allowing that.
BUT, providing a path to achieve this for the average gearhead does NOTHING to serve state level interests lol, such as selling more new vehicles/alternative fuel vehicles/EVs.

Can you cite any sources for what you're claiming? Program name, form numbers etc? Never heard of anything like that before.

I usually get SENT to the smog ref. be advised, it's NOT easy, anything that doesn't have carb oe numbers on it is going to be inspected to be sure it doesn't interfere with any smog related components, which is basically everything listed on the underhood emissions label, in very rare cases you can get an exemption for something like egr not being there ( it took a police report and scrap certificate to get them to let me run my non egr z6 in a shell that was originally equipped with a b7 with egr). Evap, cat, heated o2, ect must be functional, and the gas test must be below average. And of course these things only apply to pre obd2 vehicles, as they stopped running gas tests on obd2 back in like 07 or something when they found that after 5 years 90% couldn't pass the gas test without ridiculous amounts of repairs.

So you got sent to state ref, which is nothing like what you described previously.
B7 does not have egr.

That's what I thought too, but I guess a few 92-93 cars came with a vx manifold for some reason, and the egr valve was a dummy, basically just there to block the vacuum side. I've seen one or two through the years and always just figured there was some strange swap choices made.
My personal car is only one example of loop holes I've used with the smog ref, my wife's 90 lx got a mpfi swap with obd1 stuff that needed paperwork done, the injectors and tps were discontinued so I was allowed to swap the entire injection system.
My dad's 83 f350 Had thermal vacuum valves that couldn't be sourced and 4 different reman carbs with warped or cracked bodies, so I was allowed to run a crudrajet and rig a vacuum rectifier off a Toyota camry to control the egr and bring the emissions into compliance.
Most recently an 80 suburban got a 5.3 swap from a wrecked 04 Silverado, the ref even let us use the dual cat y pipe off a later model truck because the y pipe off the 04 had clearance issues and I had the other laying around in near new condition.
I've even been able to push through some boosted civics using bits and pieces of the few old-school piggy backed type carb legal turbo kits from the late 90s i find floating around and building the rest of it with newer more up to date parts.
One time I actually had to find a b18b1 auto to put into a civic because whoever had owned the shell before had done the paperwork correctly and it would have taken more paperwork and inspections to put a z6 or b7 in it like was originally planned for it.
