I did a few searches and didn't find any definitive answer.
I heard if you ordered a bare block from the parts counter at the dealership they came like this, I heard they are jdm 96-97 ITR blocks.
I can believe the dealership idea...

 

are you talking about a replacement from japan or usa , or Europe ,

I Currently Have a Replacement Block in my ITR , its a USDM ITR B18C5 , no p72 stamp ,
and i believe all jdm R motors are stamped B18C
no difference there either ( 99% sure ) same for europe (i think )

honestly , it looks as tho some MORON and i caps that cuz youd have to be REALLY TRULY RETARTED to think like what im about to say .

They heard P72 is stamped onto an R block (or heead or whatever , on the motor ) took any B-series , and stamped that into it , you know , trying to make a fake type r block .
if that is the case , they were sadly misinformed of where it says p72 , and i really dont know how possible all this is with all the b18c5 talk and what not , but on the same page , ive seen some REALLY ST)OPID things in my life , things i wouldnt believe unless i saw it with my own 2 eyes .

example For something someone would do with a rediculous situation like this : (on craigslist )
Integra type r block for sale ,
yes laddies and gents this is a real Integra type R block from my friends car , he got rear ended and wants to part the rest out
so heres the type r block , you can tell its a REAL type R from the P72 stamped on it !!
BEst motor EVER !!!!
5.000$ OBO


Other than that i have noooo idea whats up with that , but is sure as **** aint a USDM replacement block ,
**** while i was typing all this i was thinking how theres no way it could possibly be this , but WHAT THE HELL is it if its not the crap i just said above ? WOW

 

first off where in the hell did you find that picture?????


my guess is its either
A: fraudulent meaning somebody grinded/filled/stamped that stuff
or
B: it could be like a prototype car motor or something from acura that they used a year or two before the car with that motor was suppose to come out, or they used it for engineering, something along those lines


where did you get that pic though? that would be a good place to start becaus nobody on this site is going to have a definitive answer for you

I took the picture. The block is inside my garage. I know everyone is going to ask where I got it, honestly I don't remember. I bought the block and the crank when I hydro locked my motor but replaced it with a different block and this thing just sat around for three or four years.


thanks for the replies

 

so where did you buy it ?

EDIT , i read your post , im dumb

i'm not entirely sure how that block can be legit


unless someone in the past decided to take a B18C bottom end, grind off the numbers and put that in it's place for ***** and giggles

 

i have/had a jdm 96-97 spec itr swap in my old car, purchased from hmotorsonline, and this is what is stamped on it (B18C):



if that helps at all.. lol

 

HOw does someone spend ~$3000 which would be about the price of a c5 block 3 years ago and forget where they bought it? Unless it has other vin tags and serial numbers, sounds stolen to me.

Yeah really. Something about this story is

$300??? for a block and crank? the block is obviousley not stamped C5, so we could probably assume around $300 give or take a couple bucks.


take a picture of the front of the block below where the dipstick goes, right above the oil pan so we can see if there is/was a vin plate on there or,

 

that p72 stamp on the block looks so ugly i don't know why.

& Yes I'm random.

 

and my JDM ITR block says B18C and head is stamped PR3-4 if that helps..

Stolen, maybe... where do you get p72 stamps like that? Wouldn't it have to come from another block stamped p72? That is what stumps me but I guess.

I LOL at me paying $3,000 for a bare block and a crank. I think I got the block as part of a trade for a swap that I sold and installed for someone. I Forgot who exactly sold or traded the block to me (I have installed and sold a lot of motor swaps in my time). It could have been a H-T member for all I can remember (marijuana effects the short term and long term memory).

If no one has seen anything like this chances are it's a fake. People are scandalous in this world.

Thanks everyone for the input and pics.

Here are all the rest of the pictures I took. I can take more if needed.

 

I have never really studied B-series blocks, but the VIN tag has been removed (most likely means stolen block). Also, to me it doesn't appear to have the holes for the oil cooler? I am sure somebody else could tell you what it is based off you pictures.

 

anyone ?? id really like to know whats goin on with this , i still agree with my original post , that some dumbass thought p72 means type R wich it does , but not in that way , stamped it and looks dumb

you can make a stamp at home , no other block HAS to has p73 stamped to copy , with the right tools you can do anything

but the plate where the eng.code would be dosent appear to be shaved down, unless someone replaced the metal , wich id prob be able to see in that case ,

 

I have never seen anything like that before..If the motor id plate was ground down say 8-10 years ago I guess it would be blended back in with the rest of the motor...But I think you are on to something,,,definetly looks suspicious...

 

well thats really wierd, it appears that it has the jdm vin holes where the holes are there but they are not threaded becaus they dont use the vin plates in japan like we do.

and the stamp doesnt really look tampered with, or whatever mod was done to it was very very clean, and even then theres no reason to restamp it with "p72" i could see them doing b18c or something. but even then its still a jdm block becaus the unthreaded vin holes so i dont really think a thief would have a reason to restamp it since its a b18c.


..........does anybody know if the "race" model ctr and itr's the stripped out ones sold just for racing have the regular b16b and b18c stamps? i would assume so.. i think i saw a ctr ek9 race model and it was b16b.

so what that makes me think is it was probably a R&D block from honda, and unless you find somebody that works in the development parts of integra's in the usa or japan i to ask if they used something like that in thier cars then i pretty much 100% doubt your going to find a DEFINITE answer.

im just going say from educated guess that it is a r&d block from honda, and it probably ended up being taken home by somebody who didnt want to destroy all the valuable pieces of the car, either in japan or usa and it ended up being used in their personal car which over time was sold and/or parted out and somehow it ended up in your hands.

thats what i would guess anyways. anyways you should just send it to me

 

I hate to say it but this looks like the work of a very good theif. In my opinion, the numbers look crooked to me. The height difference between the '2' and the '5' definately are not the same. I'm not judging anyone or calling them a theif but it looks like a really good Re-Stamp!

 

its a good restamp

 

Honda would have no reason whatsoever to stamp a BLOCK with a HEAD code. There is no way in hell that is a legit stamp, not saying it's stolen for sure, but not OEM stamping right there.

ok, and look at the example of a legit block shown...not all the numbers line up either...

things that make it seem legit to me, the font of stamped numbers, the vin holes that arent used...

there is a way to see if it's been ground down and you can revive the numbers from the past...ill have to look through my old forensic book for the process...

i bet this was a test block used by honda...

actually p72 is the correct code for the block...

from son's acura webiste...

11000-P72-020 BLOCK ASSY., CYLINDER 1 1995 INTEGRA 2446.62 1957.30

 

I would be amazed, absolutely AMAZED if a Honda Japan test block got out into the public domain, let alone to the USA


all of that stuff gets crushed so that it can't get out, and the Japanese aren't exactly the sort of people that make things go walkies like the western world, and a whole bottom end?

can't exactly smuggle that out in your lunchbox can you

 

there are ways of getting it...like someone posted earlier, an employee could have used it for their own car, and then it got sent here with the 1000s of other jdm engines...

dealerships in the US throw away blocks/engines after they are warrantied out, so...
