3sgte illegal?, Just wondering... Options

[Legit94GT]

Going off of the topic... Can a cop make you pop...

So i guess i totally never thought about this, but would soing a 3sgte swap into a 94-95 celi be illegal?
I say 94-95 because of smog regulations and OBDII, but aside from worrying about emissions... Would it be illegal to have a celi with a 3sgte in there? Assuming that you didnt do anything really crazy with...

Same questions goes for 96-99 celi's?

Please just facts or good links to helpfull sites.

- Run the JDM engine using an OBD2 USDM ECU. This is only possibly on a handful of swaps, one good example being the 2JZGTE VVTi swap into an IS300 or GS300. The IS300/GS300 ECU and harness is very similar to that of the 2JZGTE VVTi, so you can use the stock USDM harness and ECU to run the engine, with a piggyback or standalone and some good tuning. A number of people have passed emissions this way.

I was actually thinking about doing this a few months ago, since my car is obd2. I was going to get another set of ecu plugs, and Tee them off the main harness. That way, i could plug either ecu in, if I ever needed .

we already know you can use the 3s map sensor on the 5s ecu.
You can use the intake air temp inside the afm since it has a similar scale.
Coil is the same.
Igniter will work but wont let you rev above 4k.
Distributor SHOULD be the same.

Only issue I could think of is that the injectors are high impedence for the 5sfe.

Then it would just be a matter of tuning for the 440s with an safc, and making sure the ecu sees what it wants to see from both o2 sensors that are needed to spit out the a-ok for the odb2 emissions system.

Another way of doing this would be to keep both ecu's in the car, and have the 5sfe one running off a simulator. I know megasquirt has a simulator for testing their ems that just sends out dummy rpm, coolant temp, etc... voltages to full the ecu into thinking its running in a car.

You'd want to use the 5S distributor (they are different) and igniter, and then tune the 5S using a good piggyback... yeah, could be done.
