What OBD is XSi B16A? How can I make this legal?

[Essenar]

I'm trying to cram as much information in, before I actually go out and buy an engine.

I read a link here (thanks to Pissedoffsol) that talks about how to make a JDM motor California legal. That's like a blessing from god considering the JDM B16A's are nearly 700-800 dollars cheaper than the USDM ones. The question is how to get it to work and how to get it to work right.

I'm going to use same-year or newer (92-93 Engine, 92-93 Integra Shell/Civic Shell ideally)

This part I'm confused about:

2) The engine must be the same obd (onboard diagnostics, its an electrical configuration) as the U.S. counterpart. For example, I have a 95 JDM Integra GSR. That engine runs obd1 in the U.S. so my engine has to be obd1. You obd0 B16a owners need to make your engine as close as possible to a U.S. spec Del Sol VTEC, that means obd1 folks.

Okay so what OBD is this engine: B16A XSi 92-93

3) The ecu must be A U.S. spec, and must match the obd. So my ecu must be a U.S. spec P72. B16a owners need U.S. P30’s.

I need to get a P30? How do I get that, and is that the thing that goes under the carpet on the passenger side of the car? If I get a P30 ECU, how do I keep it OBD1 or rather change the OBD to 1 and use the P30 ECU?

I'm planning on using a CARB Legal US spec aftermarket intake/exhaust manifold, since it'd be cheaper/easier than finding an OEM Del Sol Vtec manifold set up.

9) I hear some REF’s Don’t like obd0-1 jumpers

Will I need one of those? If so, what's the wa of making an engine OBD1 without using a jumper?

I know that if the XSi engine is OBD1 that means I can probably get away as long as I just get the P30 ECU.

The XSi motor is OBD1, i converted my CRX to obd1 and put one in
and it uses a cable tranny, not a hydro
and the motor should include the ECU, i dont know which one off hand but it's OBD1

92 to 95 any honda, will be obd1.
Any engine from 92-95 will be obd1 jdm or usdm.

(with some exceptions of late 91s being obd1 and late 95s being obd2 in the preludes)

If you get a 92-93 civic shell, you can use a motor of the same year, but you'll need to get a hydro transmission or use the Hasport conversion kit.

[ the p30 is obd1, the XSi comes with a pr3 i think ]

Pretty sure that at least some XSi's are obd0...prolly the pre-92's though. PR3 or PW0 obd0's.
