I'm trying to figure out the year of my motor. At the front of the head the imprints read: P72-2, 93, 90, 7, 3. I didn't think there was any B18C1's in 93. Anyone have any ideas, or another spot I can check for the year? This is a USDM motor btw, it says B18C1 on the block.

 

you can check on the gead of the motor just above the the exhaust manifold, it will look something along the lines of 9/4 meaning it was made in 94.

Is there a VIN Number. The 10th digit should tell you.
R 94
S 95
T 96
V 97
W 98

Or check the head, there should be a cirlce w/ a year on it.

 

That's what I'm saying. On the head is says 93. I know it can't be a 93, but it does say P72. Where would the VIN be on the motor? It is in a Civic so I can't use the ones on the car.

 

Well on a 96 and up, they have a green plate on the block.

 

Ya, this is OBD1 so that's not on there. Anyone know another place to look or can explain the 93 P72 head?

 

in australia 3 gen integra came out in 93 so i think there is a 93 b18c...but then in australia its b18c2.

 

Why don't you ask the motor? I'm sure he'll tell you........oh wait, he might speak japanese though...

 

The block says B18C1, but maybe I have a head from Australia or something. Thanks for the info.

Quickteg- mmmmmmkay. Thanks for the bump.

 

what does the head have the usual gsr intake manifold....that all 94 and up gsr"s have.....also acura did make some of the motors in advance before the car came out and what ever year it was made in was the year on the block.....my friend bought a bran new 2000 gsr with 0 miles on it from acura....but his motor is a 99 and the dealer told him that some of the motors where made a year in advance.....also did u buy the car bran new or used...who knows what someone before u might have down.....

 

I was kinda thinking that maybe the motor was made a year in advance. I'm not familiar with the differences in the intake manifolds, but the head is a P72. That means it is a B18C head right?
The motor is in a Civic and I was told it was a 94 B18C1. Anyway, I think you are right about it just being made in 93.
