By front shell do you mean the front-most iron or the front cover (houses the front counterweight and oil pump chain). I'm assuming you're using a 13b front iron, so depending on if you're s4 or s5 will determine what pump to use. I'm not 100% sure that they are different between the s4/5, but visually they look the same. I would just order the same-year part for it.

please define "20B front shell"
a JDM S5 T2 uses the same water pump as any other S5
the Cosmo engines use a totally different pump, it is only available thru Mazda, and its very very expensive.

Hey...Cut it out!

OP probably means it's a 20B front cover. Late in S5T2 production, Mazda replaced the N370 front cover with a NF01 one from the Cosmo. Can't recall the exact date, but I believe it was in mid-1991. Part number prefix is stamped into it, visible from the outside when installed on the shortblock.
Water pump is determined by the water pump housing. Any 86+ WP housing can go on any 86+ front cover without doing anything weird. On my 20B FC, I'm using the NF01 front cover and a N326 (S4NA) water pump housing and pump. The only thing I did was cut and weld both hose barb necks to clear the turbo outlet pipe and OMP. Other than that, it bolted on with no drama. Can't recall which gasket I used between pump housing and block, but they may be the same part. Check with Atkins Rotary or Mazdatrix to be certain.

Where to buy a waterpump?
I have a 1991 NA RX7 and I'm wondering where to buy a new water pump. MazdaTrix, Atkins? Should I return the pump that I ordered from Autozone and order one from the stealership? What is my best bet? I don't mind spending a little extra if it's going to be a better part. O'Reillys and Autozone have a lifetime warranty on theres... Thanks!!

Help to keep a Rotary on the road, anyone?

I tried creating a new thread to post my above question about what company I should go through and why. I even posted it in the new member technical section just in case members would consider this a stupid question, BUT the thread was never approved. Parts quality should be an important thing, correct? Due to no response on this thread, and the disapproval for the attempted thread, I returned both waterpumps.
As a result, my '91 S5 has been sitting disabled for the last 2.5 months, and I still have no response. I have since bought a dilapidated '91 Nissan 240SX just so that I can have transportation.
If anyone has any love for Rotary Engines, could you please show it by giving me some feedback on this topic? Who should I buy an S5 Non-Turbo Waterpump from and for what reasons? Who should I avoid? Thank you!

the root of the problem is that Mazda supplies a rebuilt pump now, so you cannot buy an OEM pump in the US.
furthermore Mazda sells the same rebuilt pump as a bunch of the chain stores, i think its a cardone, Mazda is $70, the chains are usually cheaper.
i see new pumps from gates, which is scary, bosch, which is worse, airtex which is not as good as your bad OE pump, and airtex, which is a mystery.
there is also beck arnley, and since they mostly rebox stuff, it might be good, or it might be a turd.
i see an NPW which at least is japanese…
so you have plenty of choices, none of them that great.

I ordered both water pumps from O'Reillys and Autozone, and had both pumps sitting in front of me for a few weeks. The O'Reillys gasket was broken due to a lack of packaging material inside the huge box it was shipped in. The Autozone waterpump came with a good gasket, but they couldn't even get me a thermostat gasket. Each pump was about $70, about half the price of Mazdatrix @ $136.26, and Atkins @ $135.

(12-29-07) Back in 2003 I put a remanufactured water pump from O'Riely Auto parts on my car. It finally failled about amonth ago or started leaking pretty bad anyway. The original thread is here.
Remanufactured water pump.Anybody used one? - RX7Club.com
So I got about four years out of it and since I don't drive it as much now that I have a truck I'm guesstimating about 40k to 50K miles out of it... So in short the reman didn't even last half as long as the stock one. Others may have better luck. If you buy a parts store reman make sure it comes with a lifetime warranty.

I paid 79.99 at Autozone (Duralast:"New" Limited Lifetime, and who knows who made it because Duralast is all reboxed stuff as well). They also have a Valucraft Remanufactured for 59.99w/1yr warranty.
O'Reillys has a 66.99 Masterpro(says Cardone in description)Remanufacured/1 yr. warranty & the 76.99(Import Direct New w/ broken gasket lol, limited lifetime.)
Napa has a new Napa Tru-Flow for 72.00 and a reman Napa for 69 that actually has a limited lifetime warranty on it.
So I probably shouldn't purchase one from MazdaTrixFan Clutches, Water Pumps, Thermostats, Belts, Pulleys or Atkins Rotary86-92 Rx7 Water Pumps?
Both Atkins Rotary and MazdaTrix do not specify whether the water pumps are new or remanufactured, and do not list any warranty info or part supplier info?
Thanks j9fd3s, Dak, and RXSpeed16 for your swift responses!

I'd pick one with a lifetime warranty maybe the NAPA reman. At least it most likely started life as a Mazda pump. Only if Mazdatrix or Atkins will give a lifetime warranty would I consider them. Otherwise you'd be just as well off with one from the local guys and a warranty.
I was going to go with the Napa Tru-Flow NEW water pump, but I just called Napa to order it, and it's made by Gates!
I want to get a new pump and not a remanufactured one. From what I've read it might be smart to stay away from rebuilt pumps due to their short lifespan of about 4-5 years? If I bought a good quality new one, wouldn't that be better than a rebuilt Mazda pump? Even if both have a lifetime warranty, I don't want it going out in a couple of years and having to do the job again.
Anyways, Napa is out of the picture
I agree. I went to their sites and asked myself "what is so special about these pumps to be asking $140.00 for them". Especially due to the lack of information on each site regarding the pumps. Not that the two companies don't have some very necessary rebuild kits and parts. And I still don't understand why Mazda doesn't make their own new waterpumps anymore.

The way you say that makes me think that there is the slight possibility that it could have started life as a new bosch as well I think I should go with a new pump? So I called Napa about their Tru-Flow new pumps...

As long as the impeller is identical to Mazda's I would think there shouldn't be any issues with cooling. The passages are in the wp housing. I figure with any of these new or remans it is lifespan due to quality of the bearings and seals but mainly the seal as that seems to be the main failure mode. Seal fails and it starts leaking.
You could be a guinea pig and buy the NAPA/Gates(though the Gates is $58 on rockauto.com) and report back when it fails as I did on my reman.

I called Maita Mazda in Sacramento, Ca. Their parts department said that there were 3 New Mazda Pumps w/manifold for $338.49 and only "1 new Mazda water pump body in the world for $376.86".
I also called Razzari Mazda in Merced. They first said that the Water pump was "New", but when I questioned that, he double checked and confirmed that they were reman'd and cost 67.70. They also said that there were no "New" pumps left, and the Mazda Pump w/ Manifold was available for $376.00.
I think that one of the dealerships was confused(probably Razzari, because at first he said that I had a 12A engine). Regardless, I figured I would just reconfirm that Mazda USA doesn't have New pumps, just remanufactured.
Do you know how much a New Mazda Water Pump from Japan would cost?
I'll agree with the odds that it started life as a Mazda pump.
So then would Mazda remanufactured pumps have the best Bearings and Seals? Better than a new Gates pump?
I will definitely post when I install a new pump.
Maybe I should just buy the reman from Mazda for 67.70 if it has a lifetime warranty(I forgot to get the warranty info, sorry. I will call again tomorrow and post that info here).
If the Mazda reman does not have a lifetime warranty, I am going with the Gates pump.
I called Autozone and they revealed that their New "re-boxed" Duralast Waterpump is made by Torque-Flow...Probably gonna stay away from that one.
Just to recap on the parts stores NEW waterpump brands(all have Lifetime warranties):
O'reillys new pump is Import Direct.
Autozone Duralast is Torque-Flow
Napa's new pump is Gates Tru-Flow
