I have been trying to find out what the b16a5 came out of. on my engine block, it has the "b16a5" stamp. when i search it, i find many people saying that it does NOT exist. obviously my block stamped b16a5 proves them wrong.

anyways, what did this motor come out of? i did find a post that said it came out of a 96-97 sir? true or false?

kaiba

Yes it does exist.

kaiba

Where ever that engine came from. It's not from Japan. JDM Honda engine doesn't use number at the end.

Question; what does it matter what car it came out of?

james_moore

Just piece of mind. Since i did not build the car, i am trying to find out as much as i can about it.

the person i bought it from, i cannot contact them anymore to find out.

I found this in 5 minutes.

Someone beat me to it.
Google is your friend.

james_moore

thx

james_moore

okay, so with all of that being said.

for another piece of mind

what is a SiR? and if i am reading correctly, my b16a5 IS a true jdm? which confuses me because i always read that JDM does NOT have numbers, it would only be B16A, not B16A5..

kaiba

SiR is just the trim level. CX DX EX Si LS GSR TYPE R... etc

Either that engine is from the Asia market(non-japan) or Australia.

Again google is your friend.

All this nonsense B16a is totally out of Japan. Mine was imported from Japan./ here in Jamaica that is where we get out used engines from. Of all the B16a engines it is the one with the most power, spitting out 174 hp. The only B16 that is more powerful is the B16B that comes in the type R civic. The b16a has the following series or generation. B16a1, B16a2, B16a3 B16a4 B16a5 b16a6, the b16a6 is rated about 150 Hp. I will also Rubbish the comment that it only comes in automatic transmission, mine was bolted on to a manual transmission. It comes with a ys tranny

virgineg6

Yes but you said you have a b16a the OP has a b16a5 , notice the difference.

Canada received sir's to, i believe it could be from there.

james_moore

before this site, i did read it could be from canada, also i have read that it is the only jdm b16 that has a number stamped on it "B16A5" rather than just "B16A." But despite all that I have read, i called the honda dealership and they told me that it also came in a del sol Si. I will have to call and ask them again, but there were a couple cars it came out of according to them. depending on if they know anything... lol

james_moore

I actually also found this... the person that posted this, originally posted it in russian. supposedly this motor is russian..

Its still the B16A2 here in Canada.

Please take a look at this thread>>>.Differences between B16A motors

B16A Motor Guide - Describing the Differences

There are 4 general classifications for B16A motors:

* B16A SiR
* B16A SiR II
* B16A2
* B16A3

It is often confused as to which motor is which. In this article, we will help you to pick out the clues as to which motor is which, and which one you should get for your B16 swap.

Although I just noted that there are 4 classes of B16A's, we can break that list down into two groups.

Our new grouping of B16A motors:

* B16A SiR
* B16A SiR II, B16A2, B16A3

Why this breakdown?

It all comes down to OBD. OBD, or on board diagnostics, are broken down into levels, based on the years they are instated. For more info on OBD, please read our article on OBD - Explained.) The B16A SiR, commonly and mistakenly called the B16A1, is an OBD-0 motor. This was the first level of OBD installed on motor ethicals. The other 3 are either OBD-1 or OBD-2 motors.

The SiR was designed for a 4th gen chassis. It works great with an 88-91 civic. However, try putting this motor in a 92+ civic and the problems will just start to flow. The tranny on the SiR is cable. the 5th gen chassis uses hydraulic actuation.

Why is the SiR cheaper?

It's cheaper for several reasons. First, it's older. Second, the A2/A3/SiR II have a higher demand, as they work in newer cars and have a higher output.

How to tell the difference between an SiR and an A2/A3/SiR II

* SiR uses a cable tranny- 5th gens are hydraulic
* SiR has a lower compression ratio, 10.2:1 and makes 160ps
* A2/A3/SiR II have a higher compression ratio at 10.4:1 and make 160hp (A2/A3) or 170ps (SiR II)
* A2/A3/SiR II motors have a better cam profile
* A2/A3/SiR II have better oiling functions, keeping things better lubricated
* SiR has cast aluminum oil spray bars while the A2/A3/SiR II are made of extruded aluminum.
* A2/A3/SiR II have a single- 4-wire O2 sensor instead of 2-single wire O2 sensors
* A2/A3/SiR II MAP sensor is an integral part of the throttle body, not an external one with a tube.
* A2/A3/SiR II harnesses are grey. SiR has cream colored ones.
* SiR is PGM-F1, clearly labeled on the intake manifold, andA2/A3/SiR II are MPFI
* SiR valve covers have "DOHC" written in a larger font size than "VTEC"
* A2/A3/SiR II valve covers have "VTEC" written in a larger font size than "DOHC"






Additional Information

88-91 B16A's are known as the SIR 1. It uses OBD0 Ecu's, and cable tranny's. The engine serial number is usually 1xxxxxx.
92+ B16A's are known as the SIR 2. It uses OBD1 or OBD2(2b), and hydraulic trannys. The engine serial number is usually 5xxxxxx
The #'s at the end of the block code tell where the engine originated from. The Americas, Europe, Austraillia, etc.....
ALL Japanese engines, generally do NOT have a number after them. (** see below)
SO, if you have a B16A1,2,3,4, or 5. It is usually NOT a true JDM engine. Don't mistake a B16A1 as being a cable unit, because it could be a hydraulic. There are other ways to tell what year it is exactly.

**NOTE: There is ONE exception to this rule. In 90-91, the Civic/CRX SiR came with a B16A1, but they are SUPER rare, and came 160HP with 10.4:1 compression. Their counterpart of the same year was a 158HP, 10.2:1. They are very difficult to tell apart.

Which motor is for me?

If you are swapping into a 4th gen, the SiR is the best choice. If you are swapping into a 5th gen, the SiR II or B16A3 are your best choices. If you are swapping into a 6th gen, the B16A2 is your best bet. Using that method above, wiring will be much easier, and its more of a direct swap than any of the others.

Also, please check local laws before purchasing any motor. California and other states are very strict about swaps. Know what is legal and what is not before hand and save yourself the hassel.

OK, the pistons in b16a1-A4 is the p 70 pistons, whilst the b16a5 carries the p30 pistons, the top of these pistons are more dome shaped, gives higher compression

b16a1,2,3,4,5 here made in japan but for markets outside out japan. (hong kong for one) the b16a1,2,3 came in obd1 eg's and the b16a4,5 came in the ek4 models. b16a4 is the manual version and b16a5 is the automatic version. the b16a4 has manual cams and different ecu and rated at a higher output of hp and torque but the b16a5 with its auto cams and ecu gives better mid range torque that its manual counterpart
