I have a 94 Integra Rs. The guy who had it before me had an engine swap. he claimed it was a b18a1 but someone scratched out the plate on the engine where is normally says what it is. Ive looked in a honda/acura manuel and im convinced it's a CR-V engine. My friend said to look at the front of the engine at the top of the header for numbers. All I got was; on the left it said
H M and on the right it said PR4-6. Is there any other way to find out what engine I have?

Heres a picture on my engine.

its a k24a2

 

What car did that come from? Is there anyway to know what year it is?

 

it came from the 94-97 integra bro the vin is under the oil pan crawl up under there and it will say k24a2

 

Alright ill go check. Thanks.

 

Didnt see anything labeled under there..

 

lmao...well darn

 

I never though vin numbers were under oil pans. Did you lie to me?

 

He's ****ing with you

Sounds like a stolen engine

 

Great forum you have here. Seems no one can actually help anyone.

 

Wow dude.... Really ? 94-97 Teg with a K24 stock? Wat ****in world are you in homie? First of, 94-01 LS Integras would come with B18b1. K24's are out of the 2nd Gen (02-06) CR-V's, 1st Gen or 95-01 came with B20. Trust me bro, you would be able to tell if your Teg had a K24 swap. The easiest way to know is the fact that the headers come out of the back & the intake manifold is in the front (Unlike OBD0 thru OBD2 Honda engines which are facing the other way).
Chances are you got a B20, which is a torque master of an engine

 

What a f*ggot troll. There's no VIN #'s pre-1996. So you have a 90-95 B18A/B?

 

I really need to know for sure though. Is there anywhere else i can check? Ill take more pics of the engine if you need.

 

K24A2 < LOL thats funny. its a ls for sure.

 

The white tag on the inside of the door says its an RS.

 

Man,

It's a B18B. Judging by your valve cover.

 

Anyway to know what year its from?

 

These years came with the valve cover that you have.

 

You're a ****ing douchebag. Honestly.

Obviously he's a newb. Why you ****ing with him like that? Why can't you just help your fellow Honda owner?

 

Alright. So i pretty much have a 90-95 b18b1?

 

yelnats has been issued an infraction for that asinine series of posts. that type of behavior is completely unacceptable here.

OP, when i used to build d-series (sohc engines), there was some data out there regarding the numbers on the head, in the casting, to help identify specific years for head. if there is nothing on the block there might be some info cast into the head to help ID at least the head, but i am not sure. i assume your concern is whether this is the original engine to that integra?

 

90-93 DA9/DB1 B18A

94-01 DC4/DB8 B18B

 

***.....

but yea, basically a non v b18 from an integra. That also might be hot.

 

By lookin at the valve cover Its either B18b1 or a1. look at the head code, If it reads p-75 its an LS B18b1, but the problem with that is that B18b & B20 used the same head castings on 96 & up LS Non-Vtec DC's. But thats not a B20 valve cover (B20 valve covers are also identical to the valve covers for LS Integras newer than 96) So unless its a B20 with an LS valve cover its either b1 or a1

 

My concern was just identifying the correct engine I have. Would taking the valve cover off and taking a pic help?
