Mechanical Changes On RX-8 Series I to II

It's not a new engine, they just moved things around, like u said, oil filter location, etc. that's why they have to create a new part number for it, think of it this way, it has different MOUNTING point here and there. but in a nutshell it's the same freaking engine.
keep in mind you CAN fit a S2 engine into the S1 engine bay, assume you know what you are doing, you can make it work. first thing first u gotta plug the extra nozzle found on the housing, then u gotta work with the rest of the stuff. if you can do all labor, it's not that hard, just time consuming.
btw the oil filter location change was because ---- people are bitching about the current location. I can remove it fairly easy, but lots of people's brains are dead and bitch about it.
yes, they are testing new stuff on the S2, most noticable is the new E-MOP with 2 seperate pumps. system works ok I guess. but there are too little S2 out there to be able to tell if such system works or not.

Do you work at a Dealer or MNAO?..
And yes I have already posted 'most' of the changes year ago, and yes most of us know all about it and there were no other changes 'mechanically' on the 2012 Spirit R...it is all cosmetic.
And YES, N3Y4-02-200A Engines (Manual) was/is still used in the Spirit R.
You are a bit all over the place... with a few errors..like..
Well No, for 6 Port Engines Stationary Gears are all the same for all Series 2004-2012 Renny's.
N3H3-10-E10C Rear Stationary Gear O Marked
N3H3-10-E1YC Rear Stationary Gear Y Marked
N3H3-10-E00C Front SG O Marked
N3H3-10-E0YC Front SG Y Marked
4 Port Series 1 Auto Engine
N3H1-10-E10C Rear Stationary Gear
N3H1-10-E00C Front SG
Thanks for your info..

All the 3 irons are different and so are the Rotor Housings for the extra Injector Nozzle in Series 2 Renny's.
Front Timing Cover is different also Jackson.
But the Engine guts is still the same as the last 2008 S1...Apart from the updated Side Seal Springs which NO original S1 has.
And NO, the Oil Filter was located for 2 reasons, 1 it is all new and larger also has a higher by pass valve, and 2, the Oil Filter is now right next to Oil Pump, so now all oil is filtered before it gets close to any internals....NO rear no un-filtered oil like from By Pass Valve used in all other rotaries.

'Brain Dead' people???...
BTW, IF you wanted to put an S2 in an S1, you would have to buy a new or used S1 Timing Cover, MOP, and Drive Gear.
And Oil Pressure issues with the MOP (Mechanical) as the S2 has a totally different Oil Pump.
Wiring, blah ,blah..
Or, buy the 2 Series II EMOP's, plus all the nozzles and pipes (all different) and then work out how to make it work as S1 ECU would not reckognize
EMOP's....Then what do you do about OCV (Oil Control Valve) in S2 Engine..
CEL's....
Yep..it would be easy.

I work for MNAO at the reman facility and am very involved with RX-8 parts. (Again, I'm speaking strictly for myself and not on behalf of the company.) As you stated, for N3H2 we use the N3H1 stationary gears. For N3H3/N3M2/N3Y1/N3Y2 engines (through 2008) we use ONLY the gears N3H1-10-E00C and N3H3-10-E10C. For 2009 up we use ONLY the gears N3H3-10-E0YC and N3H3-10-E1YC. The -Ex0C and -ExYC probably do interchange (haven't compared them directly), but there must be a reason we are restricting which engine gets which gears.
So if I'm incorrect as you claim, then MNAO is incorrect as well.
My point in the original post above is that you can't mix and match Series 1 engine housings with those for Series 2 '09 and newer. They might physically fit, but enough changed that they aren't functionally interchangeable, especially the rotor housings.

Yeah, we know all this mate...about housings..
And the only difference between Stationary Gears is the 4 Port Auto Engine in 2004's uses two 0820-10-502B Bearings which does not have the extra oil holes and middle channel in them like the two NF01-10-E04 in 6 Port Engine for ALL series...as there are NO 4 Port engines used in 2009~ then naturally only one type of SG is used, whether Y Mark or O does not really matter, provided they are replaced as a set, that is front and rear SG.
I use factory EPC's, and have 40 years experience with Mazda Parts...
See USA 2004 RX-8 EPC 'screen shot' of Rear SG , also shows what you 'exclusively use' only on 2009's which Mazda says is also used on 2004-2008...same applies for Front SG "Description USE".
Nothing against you mate ,..OK.. but some of the incorrect information that MNAO puts out to Dealers and never corrects just astounds me...perhaps you can 'try' on this one for us and get them to rectify?...
I know two US Mazda Dealers and a few here who have tried and nothing changes...look
at post #16 on 2009 Injector colors and part numbers, their PDF M-Tip has been in error all this year....and still is.
https://www.rx8club.com/tech-garage-...8/#post4024252
SleepEzy a member here also works or did at the reman plant when it first opened.
I noticed you have been a long term RX8Club member, but not many posts?
Thanks anyway...

Not arguing with anything you say, ASH8. Am well aware of the differences between the 4–port auto and 6–port manual gears/bearings, as I count their use every day. Just passing along what MNAO corporate has said to use in specific engines. :D On vacation this week and cannot compare the two part numbers for the two manual gears directly, but you're probably correct that they interchange.
MNAO does not want dealers to rebuild engines in the field any more. Too many disasters, and in the US, dealer service departments in general (Mazda and everybody else) do not have a stellar reputation for major work. We even reman the 2d– and 3d–generation RX-7 engines to special order. I gather that to control the rebuild process and minimize the possibility of failures are the reasons MNAO has specified (for example) use of only the Y gears in the '09–up engines. Take my word for it that we do not mix the 0 and Y manual gears on the line. When I rearranged stocked parts on the racks, I placed all the '09–up parts together, including the Y gears Mazda tells us to use. We haven't built many N3Y3/N3Y4 engines yet anyway. The big changes such as the extra oil injectors seem to have dramatically improved these engines.
SleepyZ (he drove a Nissan Z) left the company earlier this year. Due to the economy MNAO offered employees a package including a sum based on years of service, and he took it.
For several years after first joining this forum I was full-time caregiver to my late mother and stepfather, both of whom were in bad shape. Didn't have time to post much anywhere...
Was just trying to pass along some info about the '09 and newer engines that others might find of use, especially since the major changes got little publicity at the time. Wasn't trying to get into a litany of parts numbers, but just give a quick overview of the changes so people wouldn't inadvertently mix and match Series I and II parts in the same engine. Clearly I made a mistake in posting the information and wasted everybody's time here.

It has been well documented in discussions about all these changes over many years, frankly IMO, YES the 09 (Renny 2) engine are a little more reliable, better oil pressure (oiling system), better EMOP set up, BUT, and this is a big one, we really can not compare numbers when only 30,000 2009 - 2012 models were made world wide, against 160,000 of Series 1's 2003-2008, with half of those sold in North America and half again sold in 2004-2005.
Rebuild demand will be much higher for these engines than 09's...I guess you will be seeing a slow taper off and demand as 2004 are coming out of Mazda Engine Warranty.
We know why Mazda started their reman plant..because they had to with all the engine failures, it was cheaper to reman local than supply all out of Japan fully assembled, and because US Laws and the threat of being sued (owner class actions, publicity) meant Mazda had no other choice but to give an 8 year engine warranty...note the rest of the Mazda world does not get one...I wonder why...plus having to train Dealers 'how to' re-build is also problematic as you said.
Engine re-man reliability?, there have been many out of the plant where you work which have also failed more than once after installed at Dealer level..it can happen.
Perhaps if you have the time you can get my request fixed (M-Tip) 'internally' @ the company you work for?..
You are free to post what you want...
I hope you don't take your 'bat and ball' and go home
as your final comment suggests.

Definitely not, two entirely different Transmissions, very little if anything internally/externally is the same.
S1 is a 1998 design (Y6 trans)...used in NB Miata (Aisin).
S2 is a new millennium (P6 trans) first used in 2005, the NC Miata.

I have 2 of these,one as back up for my s1 rx8
the other I am planning on installing into my rx2...
trying to locate the shifter assem has been painful as no one wants to separate one from a box...both of mine came without shifter
Just noticed noticed your from ADL...what dealership aRE you at?

Tail-shafts (prop shafts) for all series RX-8 MT's are the same (Carbon Fiber), so yes will fit any series 8 trans, 5 speed or 6 speed...if that is your question?
Clutches (CP and PP) are different Part Numbers between 5 speed trans and 6 speed trans, AFAIK the 6 speed is obviously the most common and is just slightly heavier duty than the 5 speeds, remember ONLY 6 speed MT's were sold in AU and USA.
I do not currently work @ a Mazda Dealer.

If this is true? Does the P6 and Y6 (s1-s2rx8) gear box share the same spline on input shaft? As I have 2 P6 (s2 rx8 GT) gearbox in my shed and am looking at installing one into my rx2 sedan.
He also said that FC turbo tail shaft yoke will work...so I'm assuming output shaft is also the same as S5T...?
REason I ask is that I have plenty of available FC rx7 parts,which aRe also a lot cheaper and readily available than rx8 parts
Thank you for your time
Oh and What dealer were you with? I have a few mates who used to work for Mazda

They are the same spline size and you can use the same clutches from FC, FD and RX8 and the Fidanza Aluminum light weight Flyhwheel is the same for all 3 engines, utilizing different weight counter weights... And drive shaft yoke sizing will be the same as well since it's the main shaft front to back, not sure about length since I have a totally custom setup in a non Rx7 car.. I had contacted clutch net and asked "Verified" that their FD clutches are the same spline pattern as their 8's and one is cheaper than the other lol
Read this page on Rotary Transmissions from the link below and feast your knowledge banks ... Altho you will encounter a slight problemo with the Rx8's clutch slave cylinder hitting the FD's oil filter, I asked in another thread if anyone knows of a slave cylinder that will fit and work perfectly with the 6 speed to FD engine application but I got no answer so either no one knows or hasn't responded yet, altho it has been done a few times before right ? Anywho after looking for clutch slaves that look alike and might fit, I bought a slave cylinder from a 2005 Mitsubishi Eclipse 2.4 L and "Made it fit" (just hasn't been tested as of yet) but looks like it aligns properly just have to see if it will hold the pressure since the two mounting holes had to be drilled out bigger to match the mounting threads and it needed to be spaced upward unevenly to the right angle, it needs to use the 8's slave cylinder push rod as well...

ADL! Sorry,what I was trying to ask was...my good mate told me that the S5 FC rx7 turbo clutch and flywheel will work with the rx8 6speed,using rx8 starter motor.
If this is true? Does the P6 and Y6 (s1-s2rx8) gear box share the same spline on input shaft? As I have 2 P6 (s2 rx8 GT) gearbox in my shed and am looking at installing one into my rx2 sedan.
He also said that FC turbo tail shaft yoke will work...so I'm assuming output shaft is also the same as S5T...?

Many of the clutches (brands) Mazda source from and use are similar, almost identical to physically look at, materials and their wear factors can be another issue, however, FC and RX-8 Part Numbers for clutches are not the same.
Some Engine stuff is.
As far as installing a current trans in a 40 yo RX-2 (S124A), all I can say is try it, none of the part # are the same...one is a 4 speed the other a 6.
In the end all you can do is try it, but good luck with shifter matching holes in floors, etc.
Edit: Just so you are also aware many issues in the RX-8 (LHD) Clutch Pedals failures IMO is because many (almost all) owners have had their flywheels and or clutches changed. Particularly to heavier duty pressure plates and clutch plates, so what happens more leg pressure use/changing over time results in stress/bending/breaking of OE part.
Mazda engineers (specify) parts to fine tolerances/weight, change this and issues can occur.
There has been no epidemic of RHD Clutch Pedal failures anywhere else in the world that I have heard about (exact same design principal).
Brettus from New Zealand broke his RX-8 RHD Pedal after years of use, and guess what he also put in a heavy duty clutch.
BTW: The Racing Beat website is not correct as RX-8 trans ratio's are not the same and indeed the transmissions are completely different internally between a Series 1 and Series II, the SII P6 Trans is designed off the NC Miata/MX-5, but heavier duty in some parts and some different ratios.
Input and output splines are naturally the same as they use the exact same OE Clutch and CF Prop Shafts.

UK..
Header (Exhaust Manifold) and rubber Hangers are the same for all Series RX-8...that is where it "technically ends"..
CAT's are different, S2's (R3) has a later updated converter about $600 USD more for OE replacement to the S1.
Mid Pipe is also different according to Mazda you can use a Series 2 (R3) on a Series 1 with modification and plus additional parts (they don't tell you what to use) but not used the other way around...(S1 mid on a S2).
Muffler is different on S2 (R3) as the twin outlet pipes are bent closer (lower) to the ground, some guys have added extra Hangers so they can use after market Mufflers made for S1 (2004-2008) on a Series 2 (R3).

so in a nutshell if i was to buy the HKS single exhaust system for the r3 it wudnt be a case of simple bolt up? (except bumper mod) ie the pipes are bent to different angles or a different route?

Would have been good if you had asked this first ?
From memory others have fitted HKS OK with some slight mods to clear bumper outlet..

sorry i didnt mean i am limiting myself to that one exhaust, only used as an example as im thinking of getting a single exit but wanted to know of any drastic changes that could make it impossible without serious custom fitting, i dont suppose you can remember who did this kind of mod? would love to get some first hand advice and reviews

Racing Beat and Milltek catbacks are advertised separately - ie there is an S1 system and an R3 system - which your comments explain.
That said, most of the catbacks I've looked at on UK websites specify that they fit all models 2003-2011 (I'm looking for one to replace my much-loved RB Quad-Tip on my R3 to sell her and the younger R3 that I'm buying has a different aftermarket one that I want to keep or sell on). Can so many be wrong? It looks like they are . . . . . .

this is exactly the problem ive found ian, all the websites here say that but in the usa they seem to always have 2 separate systems for series 1 or 2, very confusing...........
if i can find a definitive answer on fitments, what make and how much would you be wanting for the aftermarket one you may be selling?
