I'm interested in a b16 but I'm not sure which one would be best.... I have a 98 hatch.... don't really know if a b16a2 or b16a1 would be better.... also better to go USDM or JDM.... would be greatly appreciated if someone could help me out

p.s. I already used that big red button in the sky

An OBD2 B16 would be a little easier to install, wiring wise.

As BlueIntegraBoy said, an OBD-II B16 would be best for an OBD-II chassis, less wiring.

B16A1 = OBD-0 = &lt; '92
B16A3 = OBD-I = '92-'95
B16A2 = OBD-II = '96-'00

Yours is a '98, so get the B16A2, and I think you have to change the dizzy plug, but that's all (I think).

Also, you'll need an OBD-IIa to OBD-IIb conversion harness so your ECU plugs in.

Most of the other crap (wiring wise) will be the same.

PS:
It's better to go JDM, they have a slightly higher compression ratio so you'll have a bit more power (The USDM B16A2 is rated at 160bhp while the JDM model, the B16A, is rated at 170bhp.

BUT

(wait for somebody else to confirm this)

I'm pretty sure the SIR-II (JDM B16A) is an OBD-I motor, which means you'll have to do a bit more wiring wise (nothing heavy), so take your pick from there. You have to wire up the distributor, injectors, and alternator plugs to make it happen, other than that, no big difference, and I'm not even positive if the JDM B16A was OBD-I or not.

93egSLEEPER

basically from what i gather you have to decide if you want to convert to OBD1 or stay with OBD2. IMO OBD1 is much easier to work with and typically has less problems with emissions,CELS, etc. if you could get a complete SI swap (b16a2) then id go with that but if your trying to just piece a swap together (JDM block, A2 head etc.) id go OBD1. Im running JDM block and bottom end (10.4:1 CR as compared to USDM 10.2:1 CR) with a 00 Si head and IM but ran OBD1 chippied p28 on chrome and its badass. all depends on how you wanna do this bad boy.

@ OP:
Welp, then there ya go, JDM B16A (OBD-II) would be your best bet.

If you wanted to stay USDM (for whatever reason):
B16A2 is our OBD-II engine.

If you bought an OBDI or 0 for your OBDII car you would have to change the ecu, harness, injectors, distibutor and the altornater.

The b16A is the jdm model, It came with P30 piston that increased compression that resulted in the 170hp instead of the USDM's 160. Also the B16A did come in all OBD modles as it was offered in other countrys since 1980 threw 2000.
But the only difference in the b16A to the USDM b16 was the pistons.

All the other B16's A1 A2 A3 are usdm model and there the difference ia only the OBD.

Hope this help. I ran into the same question with one of my swaps back in the day.

JDM B16 ftw! Should be a pretty straightforward swap. good luck.

wait i thought the Jdm Sir-II was obd1? being that in came in the sir from 92-95 and that the p30 ecu that comes with that motor is obd-1

i say the USDM B16A2, it'll be easier on you. you'll pass smog with flying colors and still be fast.

wicked_b16eg

The OBD's very just like they do here. Use your knowledge of the usdm's of odb and it's the same for JDM's. Just go with the year motor for your car. It's less work. I used a obd 0 block and a obdII head and changed them both to OBDI for my setup. Just get what you need for your car.

eric_ches

ok, there has been a confusion here. the B16A SiRII is an OBD1, because i have it in my sedan. the body is a 93 civic and it bolted on easily, no conversions necessary. if you want to swap without headaches, get the USDM B16A (from the 2000 Si), that is an OBD2. but you can always put an OBD1 and OBD0 on your OBD2 car if you like

B16A SiRII is OBD1.

You are right about the CR part.

And too that dude out there that fought with me saying "all B16A's have the same CR no matter what DM they're from" shut the hell up and learn before you speak.

Nice info. You obviously know your **** about B16's.

So the JDM SiR-II is OBDI.

Indeed. All JDM B16A's have no # designation. There's just B16A & B16B, no #'s.

The 92-95 JDM B16A2 out of the SiR II EG6 chassis is an OBD1 engine as the serial # will testify. starts with a 1 it is OBD 0, starts with a 5 it is OBD1.

kevo1586

Thanks everyone for the info.... I would like to go OBD-II if poss.... but even if I decide to go OBD-I, I don't have to worry about smog.... Canada

The year of the motor doesnt matter. The outside parts is what makes the diffrence. Im running a obd0 b16 and it was so easy to put in my 96 coupe. I used my stock injectors, B-series alternator, and obd2 distributor. Than, just ran two wires to my Obd1 ecu.
