Most Upgraded Starter
 

Hey guys, do any of you know what the part number is for the most upgraded starter on our 8's? I have a 2006 GT Auto, and I'm looking to buy the most upgraded starter for it. I don't know where to start looking, I'm certainly not buying it from the dealer.

didn't realise there were degrees of upgradedness for our starters ....


Pretty sure there isn't an upgraded starter for the auto anyway (just the MT)

Yeah...... all of them have been upgraded, lol. Originals were N3H1, upgraded to N3H1 A, upgraded to N3Z1, upgraded to N3H1-18-400R-0A

Look at mazmart and online mazda parts.

Skip Bosch, they sell old starters regradless of year.

then, go get whatever from 2007+ will get u the faster version

to be sure, The kw rating will be different. faster model will be higher (different teeth too)

Oh yeah I know, I've checked online and I still can't find anything. Mine has it's original starter, and it's 2kw, but it's still the slow version.

you do know starter is a wear item right ?

only on a rotary ..................:sad:

Have you tried the service/parts manager at your local Mazda dealer..I'm sure if it exists..they should have a part number for it...just a suggestion

Yep, all they had were remans

New ones are no longer available.

There is nothing wrong with a Reman as long as it works. Some company does reman better than the others.

Keep in mind some brands (like Autozone) offers a lifetime warranty, but lifetime warranty doesn't mean shit, what you want is a quality starter, not a starter that has a lifetime warranty but u have to replace it every 3 months because it keeps on failing.

OP...


For the Manuals the S2 OE Starter is the latest and spins the fastest at Ring Gear/Flywheel it has 14 tooth Gear.

The upgraded (2005 MY) S1 Starters went from an 11 tooth to a 13 tooth Drive Sprocket, for Manuals.

Now I can't confirm , but I think the S2 Auto's had a similar/same change, the Part Numbers are different to S1 Auto.

Since you have an S1 Auto, I can't confirm the updated Auto Trans S2 Starter will fit OK in S1 Auto, like the Manual S2 will/does in a S1 Manual....

Now you might still find that MNAO Parts has some Brand New Genuine OEM S2 Auto Starters and Not Re-mans as S2 Auto Starters are not known to give issues....
even though MNAO are using a Re-man Part Number for supply, you might just find the S2 Auto Starter inside the box is OEM and not a re-man?..

You will have to get a Dealer to check with stocks.

N3H2-18-400B is the S1 Auto Starter (upgraded), N3H2-18-400 R0B is the re-man part number.
N3R3-18-400 is the S2 Auto Starter, N3R3-18-400 R00 is the reman part number.

I am pretty sure the S1 Auto Starters (N3H2) are now all re-mans...no OEM's...like the S1 Manual.

sometimes all the old starter needs is a good cleaning out.........

that is true and that's why I kept my old starter

S2 Starter is a direct bolt-in with a S1 correct?

Yes, for manuals (stick), there have been one or two here who have done so.
Can't confirm with Auto's..I think it should.

I had TSB 05-007/08 done to my 2006 6 speed automatic. It involves replacing the torque converter with an updated design and also a new starter, which the dealer told me was from the S2 automatics. The part number is N3R2-18-400. All I know is that with the new starter, the engine starts very quickly. Not sure if there is an even newer part number than that.

There there you go, N3R2 is S2 Auto Starter.

in Mazda's case, the Reman is done by Mitsubishi which is the manufacturer. they actually do a good job.

N3R2-18-400 is NOT a Re-man..

As yet Mazda (NAO) do not list/sell an S2 Auto Re-man Starter

Mazda Parts - Online Mazda Parts

Note NO 'Core' Charge for S2 Auto Starter.

They do for S2 Manuals, and all S1's...All US remans have ''R00'' at end of OE Part Number.

S2 manual..note the R00 and note the $75.00 Core charge.

Mazda Parts - Online Mazda Parts

Autozone

2kW reman for 2006 -2008 Auto for $130 + $35 CORE

2kW reman for 2009+ Auto for $180 + $35 CORE

Different part numbers so likely not interchangeable

2004-2005 Auto is another different part number and also not 2kW $115 + $55 CORE

the upgraded 2kW starter weighs about 2.5 lbs more than the earlier models
.

Do you think the starter from Autozone will be faster than my stock starter?

anything new will start better(read: FASTER) than your old, worn out one.

Thanks for all the info guys, just purchased a 2kw starter from AutoZone, will let you know how things turn out when it gets here and I install it.

Cleaning starter
 

olddragger,

How would one (such as myself ;)) go about "properly" cleaning a starter? Thanks in advance.

Which AZ starter?
 

Which starter did you purchase? How did it work out?

AZ lists one part number (16017) for a 2006-2008 and a different part number (19473) for a 2009-2011. They both list 2kw. The only difference in listed specs is the weight (10.0lb for 16017and 8.41lb for 19473). The weight difference could be a red herring, since the 10.0 could be rounded.

They don't list the teeth.

I have a poor starting 04 and I'm trying to decide whether the 14-teeth starter is worth getting over the 13 teeth starter. The AZ 16017 is $50 more than 19473, but still far cheaper than any other series 2 I have found (if it is series 2!)

04-05 4 port autos are locked into the S1 starter. All others will benefit most from the S2 starter.

i just bought the N3H1 starter from Mazda, its the updated S1 style, the gear is obviously different, but the big difference is that the motor part is longer.

it did fix the hot start problem!

AZ Starters
 

AZ for 2009 and up shows only one starter, doesn't show whether it is AT or MT but the picture shows auto.

That probably means they don't have a series 2 starter (not that surprising).

It begs the question, though, of why a 2007 AT starter and a 2010 AT starter would have different part numbers and the 2010 would cost $50 more. I didn't think there was a series 2 upgrade in the starter for AT?

I have MT. I'd pay $50 more to get a series 2, but I don't know that it is worth paying $250 more for an OEM series 2 starter (price from mazmart).



I tried to get some info on specs from the online AZ live chat. That was comically unproductive.

Me: I'd like to know the difference between the duralast starter motors part number 19473 and part number 16017. Specifically I want to know the number of teeth.

AZ: I can help you with that. What is the year, make and model of your vehicle?

Me: I am not sure how the model is going to change the specs, but its for a 2007 and 2009 Mazda Rx8.

AZ: We can't tell you whether a part will fit as a modification for a different year.

Me: It's not a modification. I want to know if the 2009 meets OEM specs and has 14 teeth or if you are selling the older style starters as direct fit.

AZ: All of our parts are guaranteed to fit the same as the OEM part.

Me: Can you tell me if it has the same specs as the OEM part?

AZ: We can only tell you that it will fit based on your year and model. We can't tell you any specs.

So apparently he is just looking at the same website I was already at to launch the chat in the first place. Very helpful!

There are no remans available for the S2 Auto starter.... must be ordered through a dealer, such as onlinemazdaparts.

Here's an example of the differences between the two. The S2 one is a bit more beefy.

https://www.rx8club.com/attachments/...329_160034-jpg

note the alignment differences for the main gear between the two... this variance prevents the S2 starter from fitting properly on a 4 port.

Hmm, I wonder then what is the difference is between the AZ 2007 part and the AZ 2009 part (both for AT)?

I'm looking for a reman MT s2, so I shouldn't have any compatibility issues. My problem is that I can't find any MT S2 starters except for nearly $400 from Mazda.

Does anybody know the relative difference between the upgraded S1 and the S2 for MT? Slightly faster (14 teeth vs. 13 teeth), but otherwise is there a noticeable difference? Is the s2 worth the substantial extra cost or is the upgraded S1 fine?

Either should be a huge improvement over my pathetic 04 1.4KW starter that was never upgraded.

The S2 MT starter has more teeth on the pinion gear.

i just bought the upgraded S1 starter, and it did the job. starts are nearly instant now, hot or cold.

I'm going that way, since it is the only reasonable option right now. Thanks for the input.

Did some starter Mazda Part number research. See the attached spread sheet.

Feel free to update the info, and re-post for the group.

Replaced S1 (orig) with S2 (new) starter
 

Replaced my original 2004 S1 starter, N3H1 (11 tooth), with a new S2 starter N3R3 (14 tooth). The new unit was a bolt in replacement, with a longer motor and a smaller pinion gear holder. See side by side photos:

I purchased a generic unit off the internet for about $120. No core charge.

Hope this helps.
