Need to verify series 4 or series 5 engine parts (pics)

i got some engine parts off of ebay, they came in today and i was very disappointed to see what i thought were zenki engine parts. I emailed the guy about it as they were listed as from a 91 engine and all he says was that he was "pretty sure" that they were from a 91 engine. I've been messing with these cars for quite a while and i think i know what a zenki rotor and kouki rotor look like as well as a zenki rotor housing vs kouki housing. I'm going to put the pics up however so at least i can have sometime to show the guy when he emails me back again if he's still claiming they are from a 91.


here are the rotors, i think its clear these have a cast finish in the tubs indicating they are zenki rotors

close up of rotor 1

rotor 2

here you can see the hiroshima plant stamp on the top of the housings indicating S4

the lack of the threaded hole above the trailing plug on either housings also indicates S4 housings

any feedback you guys can give me even if its just to agree with what i'm saying here would be appreciated. thanks guys

Yep, looks like Zenki stuff to me.

Weigh the rotors to be sure.
Over 10# is Zenki.
Under 10# is Kouki.
If you don't have an accurate scale, take it to the local supermarket and ask them to weight it at the cash register - hey, don't laugh we've done this before!

It is much more JDM and therefore better. Why else would everyone on this board have a full JDM body conversion? :P

Hey, they're S4... in case no one told you. ;P

BTW easy way to tell if you ask me! On my S5 rotors you see the dip on each side of the rotor pits where it starts to dip in and then it dips in deeper? Well it's only on one side of each pit in the S5... you can probably see in this pic.
