I am just wondering if anyone knows what this means or what it is from?
It is stamped numerous places on the motor....head/distributer/ other aluminum parts...

 

normally where you buy it stamps them mine says "hmo" same spot hmotorsonline.com

 

I have seen stampings all over a 1990 Integra GS I once owned. It was a 3 letter code with a long number for security. Maybe "win" was stamped on by the owner to identify all the parts that belong to his car. It may deter theives from stealing the car for the motor.... is this a JDM motor?

 

i think you guys are right, thats not oe. at one point the owner of the block stamped it. ive engraved my initials on my head, block, transmission too. it might not mean anything to insurance, but if i see the stuff in somebodys car someday...

what about this, i have a d16z with no engine id stamp at all, i figure its some sort of replacement block. wouldnt be warranty nowadays, maybe back then before honda recorded #'s, or an over the counter item.

 

I would contact who you got it from and make sure theres not a sweepstakes going on you didnt know about.
Kinda like the golden ticket. It would be a shame if you didnt come forward cause you didnt know.

 

Yea I am guessing its a JDM motor. It has Wiesco(sp?) pistons and I am not sure about what else is done to the motor, I should find out when I get it back from the wrecking yard

 

Mine has HMO right there. Wonder if it is a stamping from a builder. My headwork is stamped from the porter

 

No mine has HMO also same spot. it means ither you or someone b4 you bought that motor from Steve at hmo "hmotorsonline.com same stamp is prolly on your head somewhere im not sure but i think mine has it on the head also.

 

I recently saw a B-series motor with this same "WIN" stamp next to the engine code. Any ideas you Honda gurus?

 

like it was said above the auto wrecker/recycler is punching it with their ID. This way people don't try to warranty stuff that wasn't bought from them.

 

I am wanting to know if anyone else has this "WIN" stamp on their block and can tell me who the importer is. Any information information is greatly appreciated.
