So I've spent the last week doing swap research only to be highly disappointed. After I pay $5k+ for Pure's Motec package how do I legally drive my car on the street?


So the real question still is when is someone going to figure out how to swap these cars and have them be actually inspect-able for all of us who live in states that have an OBD2 inspection, which is getting to be more and more states/counties, including the state Pure Auto is working in.


Yes I'm aware that waivers are a thing, for now...

legally, you can only do something like a California carb legal swap. There's no real other way. Unless the car is registered in a state without testing

Like he said, in places with the same or similar laws as Califor, you can swap a replacement engine, or any newer engine from any make or model as long as all emissions equipment is unmodified and present. The two hardest things are not modifying the headers or cats in any way to fit, and to not modify the ECU/wiring completely and having a working car.

As far as I know you can only "legally" swap to a newer engine and you have to maintain all of your emissions gear. Not sure if that is from the donor vehicle or the original chassis. Probably donor. So really you just have to figure out how to get a Honda emissions setup to work with the chassis

I'm not sure that there headers would need to be unmodified, but the cats will have to be intact. Might have to use a CARB certified header and try to modify that just enough to make it work? I think so long as you don't mess with the cat or the visible part of the tube above the cat you should be ok there. ECU, I dunno. You could argue that it's an integral part of the emissions system but really (for example) if you flashed a new tune on your stock ECU it's not really the same anymore so I don't see a reason you can't use an after market ECU so long as your tune is clean. I find it hard to believe anyone will look at the ECU itself to check if it's OEM if you pass the sniff test.

Obviously it's going to be at least some more work/aggravation getting the car approved. You could always just fly casual and don't tell the inspector that it's the wrong motor.

Or buy a different car/mod the FA20. Obviously not ideal but if you don't think you can get it approved, don't start the project because you'll lose a fortune when you try to sell it

I'm fully aware of Cali law, which in many ways might be an advantage of sorts, you can take your functioning swap to a referee, prove it's as it should be and go on your way, no OBD2 nonsense required. Unless I misunderstand the process. (I'm not suggesting that's overtly easy, but it's doable and has been done).

My issue here is that the in MOST states that do inspect it's a simple OBD2 scan test on anything from 96 up. If you can get the the OBD2 to function properly you're in business, regardless of exact configuration (unlike cali). You pull in, plug in and go, if the VIN pull on the ECU matches and the monitors are good you're good.


Is anyone working on getting the OBD2 "working" enough to pass that test?

You won't find much help, as it's illegal to "fool" in any way the OBD2 systems.

Moving to a non testing county or state is your best bet

So long as you aren't turning off codes you should be fine. I'm curious if a standard code reader will still operate with the standalone ECU though. I know the Nemesis at least works partially because you can take it to the dealer for problems with the ABS and SRS systems. Things that aren't controlled by the primary ecu

The hardest part is getting the "readiness tests" to be all active and display properly.

With Motec ABS, SRS work off independently and can still be accessed through OBD2.

No standalone provides obd2 monitors CEL or readings for the engine ecu.

I'm not trying to fool it, I'm trying to get it functional enough to work for the purpose of state mandated OBD2 testing on MY96+ vehicles.


Your other statement doesn't even merit anything more than an acknowledgement that it was made and it was pointless.

Again, completely aware that a standalone won't work, which is why it's incredibly odd to me that it's being hailed as "The SOLUTION" to all our swap ills when it's very clearly not. It's just a really expensive motorsports solution that works well for motorsports. I don't want a track only car, I want a BRZ with a K24 that I can use just like I use my BRZ now.


Has anyone done ANY swap that will pass an OBD2 inspection test?

Then this part alone will be the hardest part of getting it certified. I don't see any DOT official being happy about looking at YOUR laptop to "prove" everything is running like a stock car. HOWEVER, using a Honda computer with the MRS adapter might work. Or alternatively you could use a Honda computer and harness, forego CAN integration and either mod a Honda cluster or use aftermarket gauges.
