how can you tell, is there something special on the engine somewhere, i think its a integra, low 90s not quite sure

 

its a b18a1, but wanna know the exact year

 

Im pretty sure the a1 was from 90-93 so that narrows it down some...i dont know if there is a way to tell the exact year...wait look on the head maybe it has markings?? I thought i read that somewhere.

nope its 90-91, b18b starts in 92-01

 

Ok my mistake..01-91 it is!

 

are you talking about the year stamp on top of your headers or the engine code on the block?

What?? That is way wrong!!


Please dont misinform people.

b18b started in 94

 

simple....between the 3rd and 4th cylinder, above the exhaust manifold, stamped in a little circle on the head.

it looks like a circle with a slash through it... 1 number on each side of the slash

for example "(9/2)" thats would be a 1992

 

i have that the same question. i got a b20b and thats all it says. how can i tell the year?

 

Hot damn i was right to begin with..WOOT!!

 

The stamp on the head does not tell what year vehicle the motor cam out of. It can either be the year of the stamp or one year after.

The best way would be the serial number on the block. Each master helms book shows the possible serial numbers for that year.

most of the time, if your motor is stock, you can tell by looking at the head, since you got the b20, most likely you will have an ls head? and the head can be anything

what are you talking about? most b20's had "p75" heads, if its a B20 then there should be a VIN tag on the block, right? If there is then you can run the VIN and determine what year it is.

 

yes its the jdm b20 and it does have that serial number. but how do i tell what the year is from that number. gota change my timing belt soon, thats why im wondering.

 

look at the head, there's a casting number... it will have the year. i believe all timing belts for LS/B20 are the same...

 

most people who run b20 run a ls head, you cant run a b20 head because the intake manifold position.

shut up. the heads are the same thing. intake manifolds are different yes, but the heads are teh same.

 

so switch ls manifold to a b20 head? yea that will work right? ok then

Does a bear **** in the woods?

 

im pretty sure b18a1s are 90-93 so thanks guys

 

wait, whats the difference between a b18a1 and a b18b1?

 

90-93 is ab18a, 94+ is b18b, spec is different

 

Some confusion comes in from the fact that 90-91 B18A's are making 130 hp, and the 92-93 B18A's are making 140 hp.

 

Compression and cam specs are different.

Intake manifold, exhuast manifold, catilytic converter... and of course OBD/electronics
