It's a turbo 13b, but I need to know whether it is an S4 or an S5. Look at the pics then tell me. Thanks!

Electric oil metering pump means you have a late model from a FC3S IIRC. Series is not a valid way to identify rx-7 parts outside of wikipedia.

 

Wait I'm confused. This motor came full stock out of an fc so I just need to know whether it's an S4 or S5. I'm assuming S5 since you said late fc. Correct me if I'm wrong!

 

S5. The s4s had a mechanical omp. Yours is electric.

 

Thanks bro

 

I'm on the lookout for anyone who can provide any information that gives any validation whatsoever to the use of the term "series" as it pertains to RX7s. So far it appears to be something made up by whatever random dude wrote the descriptions on Wikipedia. If it is legit would love to see some literature if anyone has anything.

 

what are you talking about?

series 1 1978-1980
series 2 1981-1983
series 3 1984-1985
series 4 1986-1988
series 5 1989-1991(technically 1992)
series 6 1993-1995
series 7 1996-1997(not sold in the US)
series 8 1998-2002(again not sold in the US)


yep, totally fictional.


this engine is the fictional series 5, from the fictional 1989-1991 turbo variety fictional FC3S. and guess i was right from the other thread.

i mean even this forum has subforums for the fictional series of cars.


sorry for the harsh sarcasm but it just sounds a bit ridiculous to doubt. i don't know what kind of factual data you'd need, a signed letter from the head of mazda corporate during the times of the production? this is all common knowledge, i didn't even look at the wiki page to give you those years/series identifiers.

terms like kouki and zenki were merely adopted japanese terminology during the dorifto peak.

 

I thought Kouki and Zenki were strippers...

 

but which one is younger?


and i screwed up and forgot series 8! *fails*


i feel like i've been trolled by a mazda engineer that hates the fact that the cars were broken up into sections for easier identification purposes.

 

Yes, that is the information on wikipedia... yes it has been used for several years here... yes it is a general guideline that does have some (albeit flawed) basis in reality, as does Zenki(early), Chuki(mid), and Koki(late). Not trolling I would love to find where this stuff came from, as of right now I strongly suspect a dude in his moms basement editing wikipedia. I would love to learn if I am wrong.

My point is, forgive my lack of sarcasm in saying, if it has no basis in MAZDA reality then perpetuating its use just because someone else did is harmful, and thoughtless. Especially if used in the context of finding parts, can think of dozens of examples in the FD where "series" does more harm than good when looking for parts.

Here is a better place for this discussion.

what you are implying is very similar to say the japanese trying to convert to imperial units, because they may be around in small volumes.

in the US we use imperial units standard, in some cases we may use metric but that certainly isn't the majority or the norm. your chart almost solely impacts FDs which weren't sold in the US and the series we all have conformed to here has worked so far.

the suggestion you are making is for everyone to relearn what they are used to just to suit the few it may impact. doesn't sound like that will go over too well to me, except for the references beyond 1995 which are few and far between as of now.

almost all cars have changes, the FC and FB most certainly did depending on where and when they were put together but in those cases all one has to do is say "i'm working with a nippondenso 1989 air conditioning compressor", versus i have a FC3xx or whathaveyou, since that just confuses people more. trying to get basic info already is like pulling teeth most days.


i mean i could tell you through that fuzzy picture above that the engine uses a koyo power steering pump, even though the FC had 3 different power steering pump variants.

it's like trying to make something more complex than it really needs to be, which we have plenty of in the world as it is.


but saying some noob spent all that time dissecting things into bits for layman is a bit disrespectful, it was initially written in english and most of the countries where english is a first language it certainly applies to, just like this forum. if you want to add more information to the third generation wikipedia entry i don't see what would be stopping you.

 

Agree to disagreee with your entire post. : ) It is not simple and in 100's of cases just off the top of my head it is just wrong, and he is not in the US.

Teaching the newb correctly from the beginning would take very little effort at all. Those of us headed to the old folks home are another story.

 

Take another bong rip old man. You're putting too much thought into it. The differences in FDs werent so significant as to where the "Series System" wont work for most applications.

 

hows about next time don't come into the noob area and confuse the noobs further with your derogatory terms for them and unecessary confusion of the models of cars.

you sound like another person i knew, who loved to act like queen bee and call people noobs, who i don't even think realized it was a demeaning term. he was a real fruitcake(now how do you like having a label used?).

 

Do me a favor and read above where you are the one who used the term noob/newb first in post 11, used the term to speak your language. When you call in the PC police on a frame up make sure your hands are clean next time Hoss.

So to recap your statement. You associate with fruitcakes, politically correct nomenclatures are VERY important to you, and the role of queen is already taken. Got it, the point is taken, no judgement here.

As I said, agree to disagree. Thank you for your time.






Anyways...

For the next guy looking to answer this question for themselves, if you are looking at the front of the FC3S engine to the left of the crank pulley is where the metering pump is. Like Fuhnortoner said above, if it is has no wires it is the older motor, wires its newer.

 

it must have been your rendition of a person sitting in their parent's basement editing a wikipedia page without any knowledge of the car.

 

At it again... It seems your regularly see what you want to see. This is my last effort that will be spent on the topic.

I said random(meaning nameless/blameless), not someone without any knowledge of the car. To type this you have not understood a word I have written here, or you are trolling by misrepresenting it, either way. Thank you for you time.

 

if by trolling you mean defending the wikipedia entry, then yeah, guilty.

 

you should probably re-write the wiki since you have such feelings

 

+1 on that. Open source baby, lets see what you got!

 

OP, there is significant evidence in these fuzzzy pictures that this is an S5: intercooler, electric OMP, water pump/outlet, turbo oil return, throttle body lower coolant hose, No EGR (or may be JDM)

The identifying features are backed up by the mazda parts catalog and the Factory Service Manuals from Mazda.

Some people have been kind enough to filter that information and it is available for free on the internet (a lot of it on this forum), but you are going to have to put in the effort to google it.

 

@RXSpeed16 it is imported from Japan so it is JDM. any differences between USDM and JDM?

 

Not on S5.

S4 jspec, the fuel flow is reversed.

And S5 engines dont have EGR. Only S4 USDM.

 

well, the engine harness is different as well, if it is even intact. usually they come chopped because apparently it is too difficult to fish the connectors through the firewall.

 

It's a s5
