Engine code b16a b16a1 b16a2 b16a3 ??????

[platinum92civic]

My question is The engine i bought the code on it just says B16a
with no # next to it......Ive seen b16a1 and b16a2 whats all the diff. between those codes....And again mine is off the truck from japan for 92-95 civic??????

Does anyone know?

[94civic]

b16a1 is the first gen b16a that comes of a 88/89-91 civic/crx. the b16a2 comes off a 99-00 si. the b16a3 comes off a 94-97 del sol and a b16a sir2 comes off a 92-95 civic or an integra xsi (or something like that). those are not the only cars and there are some more. i'll see if i can find a list where it shows which engine comes out of which car.

from what ive read and understand, if its just b16a without a 1 or 2 or 3, its the jdm b16a2, 170hp obd 1

someone correct me if i am wrong

that is true, but i think that if it doesn't have a number it could either be a first gen or a second gen b16a. the only way to tell the difference from a b16a1 and a b16a sir2 is by what tranny they have, colors of the engine harness plugs(white=1st gen, grey=2nd gen) and if you look at the serial code under the engine code if its a b16a1 the number will start with one indicating the 1 million series b16a's and on the b16a si2 the serial code will start with a five indicating the 5 million series b16a's. i pretty sure this is what i heard, but if someone else has something different let me know.

Dayam good looking for a minute i thought i bought the b16 for a 88-91 crx !!!! But i have the grey plug...... that i do know thats what it has on the receipt.....it says just b16a but i didnt see if the engine code starts with a 1 or with a 5 ill check that today when i go home for lunch and see then ill letcha know......i think it may be sir2 cause some other people said the engine that just says b16a is the jspec one but im not for sure i wanted to get more opinions on which it may be...cause when i bought it they said it was a jspec one then someone told me it was the regular b16a 160hp so i just wanted to know for sure ill ge the info off of my engine and ill tell ya what it says!!

[platinum92civic]

ok i went home on a break and heres what the engine says in this exact order

B16a
5405074
HM

now what the hell that means i dunno...... from the looks it may b jspec which makes my ass happy.....

But if ya know let me know!! thx

[Paonessa]

now i'm not a honda guy, but a lot of my friends are. JDM honda engines do not have #'s after the call letters. my friend has a b18c j-spec in a 92 dx. i'm almost positive you got a jdm, you lucky bastard

[platinum92civic]

Well aint that about a BITCH!!!! Now that im reading up on it...you guys are right!! This whole time where i thought i had a dayam 160hp engine i have the dayam jspec!!!!! Shit well my ass is happy shit i got it for a hell of a price too.....Thx..........feel like I just had sex now :smoker2: Shit reliefed!!! lol nah im kiddin but thx for the help yall and if u still have opinions about this engine code thing keep posting......

[civickiller]

yeah 94 civic is right, the jdm b16a1 and a2s dont come stamped on the block just the b16a. the a1 and the a2 are both j spec engines, so it doesnt really help.

did u get an ecu with the engine ? if u did then that will settle it all cause if its a pr3 or pw0 then its a b16a1. if its the p30 then its the b16a2

Lets clear a few things up,shall we.

B16A JDM 89-91 teg Rsi/Xsi civic/crx siR OBD 0 10:2.1 158hp PR3
B16A1 EDM 89-91 civic/rex VTi OBD 0 10:2.1 158hp PW0
B16A JDM 92-95 civic/rex siR (II) OBD I 10:4.1 168hp P30
B16A2 EDM 92-95 civic/rex VTi OBD I 10:4.1 168hp P30
B16A3/4 USDM EDM 94-95 delsol OBD I 10:2.1 158hp P30
B16A2 USDM EDM 96-97 delsol OBD II 10:4.1 168hp P30
B16A(2) JDM 96-00 siR OBD II 10:2.1 158hp P30
B16A2 USDM CDM 99-00 si/siR OBD IIb 10:2.1 158hp P2T
B16B 96-00 civic type R OBD II 10:8.1 185hp PCT

There are other ECU codes for the automatic tegs PR3 J00 is one of them.I hope this clears up some of the questions,and if I missed one let me know.

uh...guys...the b16a is the 170hp motor...the a1/2 both come w/ 160hp. yes u guys are rite when u say it'll only have the b16a stamped...BUT the a1/2 are both 160hp motors from the 99-00 si an 90-91 siR.

Dude did you even bother to read the info I posted.The 1st gens and the US spec ran 10:2.1 for a 158(60)hp compression,The 92-95 ran a higher 10:4.1 compression and had 168hp

The JDM B16A siR (II) and the EDM B16A2 from the 92-94 vti's ran the same.You can't say the B16A has such and such hp,because it has two different compressions depending on when it was made.It doesn't matter what it has stamped on the block,it matters what car it came from.

[KrNxRaCer00]

i kno this...it's (b16a1/2/3) in the 89-92 Civic 1.6i/VTi, 90-91 CRX SiR/SiR II, 90-91 Civic Si-R/SiR II, 94-97 Del Sol VTEC, 99-00 Civic Si ...ALL of which come with the 160hp rating. the 92-95 Civic SiR/SiR II, 92-96 CRX SiR/SiR II, 96+ Civic Vti, 96+ Civic SiR/SiR II had the b16a4 (which has b16a stamped on it) which pushes the 170hp (all of which are jdm). an yea...they vary from 10.2:1 (160hp) to 10.4:1 (170hp)

point of the arguement: b16a1/2/3 ALL come with 160hp, NO MATTER THE YEAR OR CAR IT CAME IN! its still the same motor...

JDM motor didn't have numbers and the 92-95 JDM EDM's ran a higher compression with 168hp

Why did you write the same car twice?

Once again the JDM motors didn't have a number and the B16A4 is the asian version of the motor.

So you're contridicting what you said earlier that the some of the B16's have 170hp hmmm.......
