And this is why I bought a reman a few months ago. I believe I read on Banzai's site that they now come with new rotors and housings. I haven't done a compression test on mine (I've got two track weekends on it now) yet, but it seemed awfully nice out of the box. I'll do one this week, though notapreppie's compression tester is highly suspect. :P

If what Paul has shown us is broadly representative of the average reman, I don't know why any average owner would pay only slightly less for a budget rebuild. Obviously, owners with special needs (racing, turbo, ego, etc) might be better served with a custom build.

Doesn't seem that expensive...

But if they are using new housings why are they charging a $1000 core charge?

Maybe not so much rebuild as start with it as a foundation for further modifications.
I priced out all of the components for a rebuild on Mazda Motorsports and, IIRC, the parts alone came to ~$3500. The most important (and expensive) parts seem to be included in the Mazda reman. Since you can get a reman for less than $3k now, it seems like a no-brainer.
No idea. Institutional momentum?
Mr. Pockets bought his reman from that seller and it's a genuine Mazda unit. Installed earlier this year and used for NASA TT racing. Compression tested it last night with my RCT-V5.
Front: 114/110/112 @260 RPM
Rear: 112/112/108 @262 RPM
That's a far cry better than the rebuild I got from OJ Imports who reused my housings and, after you factor in my attempt to get him to back his product, it was roughly the same price (yup, kicking myself now).
So, that's two recent Mazda remans that appear to be pretty skookum.

Meanwhile, as a result of this thread and with a Mazdacomp discount, I'm thinking I should buy one and stuff it away for when my engine finally kicks the bucket. Looks like they are building them right now.

When I was looking at my options a few months ago after finding my engine had low compression, a Mazda reman seemed like the obvious choice. I did not understand the dogma against remans, since the one I had installed in 2009 had served me so well.
Only on this site did I read that the remans re-used marginal parts. Elsewhere, from Mazda and from the sites that sell the engines, I read they had new rotors and housings. So I am not the least bit surprised by the 'revelations' in this thread.
As Jason says above, I bought mine from Jeff Haas Mazda in Houston. Their prices (on the engine and the shipping) were the lowest by a long shot. My local dealer couldn't come close even without having to ship.
Shipping my old engine back, however, was an adventure...

I need to be sure they're using new components.
I'm leery of the core charge, plus shipping, (?) it doesn't seem kosher.

If it makes you feel better, just send your core back after you get the new engine. I had mine in many pieces because I thought I was going to rebuild it. When the new one came I just put it back together with all the bolts finger-tight.
I was vague about the shipping being an adventure. UPS is simply not set up for an individual to send a freight shipment, so it can be a bit of a headache. But shipping my engine back was still under $200.

Okay, I freely plead ignorance on all of the internal workings of a Renesis.
I also have for many years been under the impression that core charges were used to obtain parts that could be refurbished and resold.
That being said, it's a 'remanufactured' engine, not 'new', correct?
So, what is not new in the engine that would warrant a $1000 core charge, 2 used rotors and a used shaft?

In addition to rotors and a shaft?
Do you or anyone else know if these are possibly reconditioned?
I'm asking to satisfy my own curiosity.
I know shafts can affordably be spray welded and remachined, are the irons and cover also refurbished somehow, or just ones in good condition are being reused?

I don't think you will find that anywhere. Sleepy-z was asked to stop sharing that info with us pretty early on after the reman plant opened and it appears things have changed now.
