ok recently i purchased a b16a2 canadien SIR engine, my dad wasn't the happiest camper about the idea of me getting the engine so he started trying to badtrip my life and he asked me a question that really stuck in my head, now both SI and SIR motors are called b16a2 i think SI is USDM and SIR is canadien, how do I tell which is which? cuz my dad is laughing at me telling me the guy ****ed me over I got an SI instead of getting an SIR lol I have an evil dad I know evil but always helpfull :D

B16a2 is just a2, not SiR.

SiR is B16a.

a2 is considered better anyway.

trustdestruction

lol

USDM Si = Canadian SiR

Same engine bro. No difference whatsoever.

B18C5-EH2

A B16A2 from a 96-97 Del sol VTEC, 99-00 USDM Civic Si, and CDM SiR is the exact same engine performance-wise.

BTW before some lamer tells me:

"The Del Sol VTEC was a B16A3 dumbass!"

The B16A3 was in the 94-95 Del Sol VTEC and was OBD1, whilse the 96-97 Del Sol VTEC was the B16A2, OBD2.

trustdestruction

what i find weird is that the B16A3 came before the B16A2... what's up with that? (as long as what i've heard is true... the 5th digit meaning the version)

your dad might say "remember the time you got screwed with the engine?"

but seriously, im not a genius and all. I just do research myself.

USDM Si = CDM SiR

Trust those guys

do a search noob, but they're the same...

B18C5-EH2

That's got to be one of the worst stretches in order to get to post a "clever" forum pic.

SiR = same as JDM B16A 170hp compression 10.4

USDM SI = b16a2 160hp compression 10.2

trustdestruction

incorrect. He is talking about a Canadian SiR.

Deetz

ALL B16A engines released in north america were 160hp...period!

In Japan, the 2nd gen B16A got an extra 10hp simply from .2 higher compression at 10.4:1 with the P30 pistons used in them.

Murk 'EM

yes that still doesnt explain why he said the a2 was "considered better" then the B16a SiR/SiR II

trustdestruction

Did it really need an explanation?

Here's the explanation:
He doesn't know what the hell he is talking about.

Deetz

it's not better, that's him just makin stuff up

Murk 'EM

thats all i wanted to see.. dont like people being wrong about **** they dont know about

every1 here is just makin this so confusin..
READ THE THE QUESTION BEFORE YOU START POSTIN!!!

AGAIN...

1999-2000 Honda Civic USDM Si (EM1) HAS A B16A2
1999-2000 Honda Civic CAN SIR EJ HAS A B16A2

SAME IDENTICAL ENGINE
SAME IDENTICAL CAR!!!!


And to every1 here....NO not all b16 engines are the same
they come with different im,different ecus, different camsh,
The newer the engine year, the better the cam profile,
89-91 B16A cam lobe profiles are the weakest of the bunch.
and finally pistons...
There are 2 types of B16A pistons in the world. JDM and US. All US B16A engines are equipped with the PR3 B16A piston. Which yeilds a 10.2 compression ratio. All JDM B16A's are equipped with the P30 B16A piston which yeilds a 10.4 compression ratio. That's .2 more points over the US piston.

DO SOME RESEARCH YO ALL...

dude that's like saying

b18c1 > b18c jdm engines will always be better than any usdm engine period learn your facts before you open your mouth, i have personally owned d15b and d16z6 and the d15 is better
b16a2 and currently running a b16a in my hatch and b16a is way better
never had a usdm gsr, but i did have a b18c in my hatch and was whopping on usdm gsr and ls/vtec hatches out there so JDM > USDM.

christian7750

You tell the difference on the block. If its Sir II then it will Say B16A and if its A2 then it will say B16A2. And whoever says the USDM version is better your dumb.

i have a civic 1992 vtec vti its idleing permantely a 6000rpm is it true that i need a new idle valve

gibsanez

I'm going to buy every single B16 left in existence and melt them so stupid threads like this don't come up anymore.

way to thread jack...start your own post or do some research ur question had nothing to do with the original post....
