hmm to my knowledge all B16a's are DOHC VTEC's with two camshafts.

theyre mainly the same, the earlier B16's to my knowledge have more webbing on the short block, making for better cooling properties over the 2nd gen B16.

Apart from that, not sure what the other differences are, perhaps cam profiles and other slight changes, such as sensor locations etc etc

hey pplz
i knoe d main difference between the first gen b16a is dat its a single cam vtec and the newer ones have double
yet the power output is pretty much the same ?
116 kw or 160 hp
was wondering what are the main differences ?

Hey Jay,

What you are refering to as first gen B16a and B16A1 is one and thesame thing - B16A1 is the first 1.6l DOHC Vtec motor.

the D16AY on the other hand is the 1.6 SOHC vtec motor.

Generally:
B16A1 comes out of Honda Civics SiRs and SiR CRXs from 1989-1991 (correct me if Im wrong)
B16A2 came out in the Gen3 CRXs and later on in the VtiR civics (once again correct me if im wrong)
d16Ay came in a Civic Vti in the EG series...

hope this clears it up a little for ya..

bahahahahahahahahahahahaha

B16a1 or B16a2 they both are DOHC

B16a1's are found in the early model JMD SIR CRX&the EF9 SIR CIVIC

B16a2's are found in the EG SIR EK SIR (VTIR) EK coupe VITR and the CRX del SOL

Aus spec have 116KW (160hp) and the JDM spec have 122KW (170HP)

the main diff for the power increase is the diff compression ratio

THERE IS NO SUCH THING AS A 'B16A1'

show me a block stamp with 'B16A1' on it please!

i dont have a pic available - maybe someone else does...

but i think generally whats refered to as b16a1 is a b16a simply because the B16A2 acually have the '2' stamped into the number.

So even though there might not be a b16a1 stamp on the actual block you can easily refer to the generation as '1' because the '2nd' generation has the '2' - if that makes sense?

unless someone has a pic to show...

I personally refer to the engines as b16a1 and b16a2 as its much easier to distinguish the differenced - whereas if you say to somoen I have a b16a they will ask - cable or hydro.... saying 1 or 2 makes the difference quiet clear in my opinion...

Gotcha buddy!!!

The UK and European EE9 Civic and EE8 CRX VT had a B16A1 in them. Unlike the JDM spec EF9 Civic and EF8 CRX, the "1" was stamped on the engine to read B16A1. The motor put out 150bhp as opposed to the JDM B16A's 160ps.

The statement should be: "There is no such thing as a JDM B16A1" :)

I'll PM CivicJim on the 4th gen forums and see if he still has the photo of his EE9's block number ::)

thanks setanta - that is the only correct response to my comment that "THERE IS NO SUCH THING AS A B16A1"

not that it has got anything to do with the topic...

sorry to original poster ;)

BEDE aka Vtechnique on these forums said exactly thesame thing to me:

JDM B16A Gen one = B16A
UK B16A Gen one = B16A1

AUS B16A Gen two = B16A2
JDM B16A Gen two = B16A

would this be about right?

B16A1 comes out of Honda Civics SiRs and SiR CRXs from 1989-1991 (correct me if Im wrong)

When referring to JDM, B16A = first gen... I NEVER refer to my engine as a B16A1, its not on the block. If I called it a B16A1, the assumption then is it's a euro.

1G B16As came in 3 flavours

JDM B16A 1million series in the XSi and RSi 'tegs.
JDM B16A 5million series in the EF8 CRX and EF9 Civic .
Euro B16A1 in the Euro EE8 CRX and EE9 Civic.

The yanks invernted the notion of there being a JDM B16A1... it's a convention, not a reality. Who gives a f*ck what the yanks think anyway :D

JDM B16A Gen two = B16A

would this be about right?

JDM B16A Gen two = B16A2 as well - same designation as the Aussie counterpart but with 170ps rather than 160bhp.

The "2" is stamped on the block unlike the 1st gen's lack of number.

But knowing were in oZ and there are no Euro B16A1s its just easier to differentiate between the generation like I said earlier.
I understand what you're saying so no stress there...

Anyway to answer your question........ lets just compare the JDM B16s.
FYI they where all DOHC.
The main differences where 1st Gen had Single Valve springs as opposed to dual and the CR was 10.2 in the first gens and 10.4 in the second.

my 3 first gen B16A's all had dual valve springs...

maybe you are thinking of the automatic versions of the B16A SPEEDCORE?

SPEEDCORE

15-11-2004, 09:54 PM

Appologies, yes the Auto 1st gen had single inlet and exhaust springs.

There is also debate whether *SOME* of the 1st Gen Manuals had dual on the intake side and single on the exhaust, which where seen in the B16 Integras of that time too.

As far as confirming this dual intake side and single exhaust side I can not speak from experience as I have not seen it in person.

Thanks for clearing that up Tinks! :thumbsup:

My EF9's 1G B16A also has dual valve springs. Autos: unless it was on the 'tegs, there was no auto gen1 B16A, the EF8 CRX and EF9 Civic never came with an auto. It was only the 2G B16A Civic's and 'rexes that got auto. I'm uncertain about the EE8 and EE9, but the workshop manual for the EE8 and the euro/JDM brochures I have for the 4th gen Civic/2gen CRX SiR/VT don't list auto anywhere.

You're forgiven for the EE8/9 slip tink ;)

I wasn't sure on the auto - I tend to focus on the EF/EE/ED more than other Hondas nowadays.
