Mazda Remans..... the saga continues
I've cracked open a few of the 'new' mazda remans for portwork/oil&coolant mods/upgraded apex seals etc since they started assembling them in VA alongside the RX-8 blocks.
Cons:
*Typical loose (but in spec) side seal clearance
*Nasty rust in lower coolant passages from being run with water and left to sit
Pros:
*So far, majority of parts (and all iron/alum housings) have been brand-spankin' new
In general, they're an absolute killer deal.... a pair of rotor housings new cost about half as much as the current reman prices from Ray Crowe at Malloy

Just to confirm... You are saying that the "new" ones are half the price of the remans when both are ordered from Ray at Malloy?
And these are the "new" ones you are showing us ?

i.e. if each housing costs you $700 + shipping, than you get the brand new housings, brand new irons (at approx $485 each if bought separate), a brand new e-shaft, new rotors, new seals, new oil pan, etc., etc., etc. for SIGNIFICANTLY less than what you would spend if you tried to piece together a new engine.
I spoke with Ray Crowe about this exact thing last fall. Essentially the "new" reman engines that he is getting are being put together with all new parts since none of the cores being turned into Mazda have usable parts. Mazda cannot/will not reuse a part if it has been ported or if the wear is out of spec. Since virtually ALL the engines turned back in to mazda had porting or significant wear, Mazda fell back on using (mostly) all new parts in their reman engines.
Mazda is no longer selling brand new 13B-REW engines (I purchased the last one from Ray
) and the remans, with the new parts being used in them, are now a viable option for people who want to renew their tired engines

I am not 100% sure what you're asking, but I think Rich is saying that you get a screaming deal if you buy a reman from Ray Crowe. Rich's example being that you can get the entire engine (which is constructed with all new parts) for just double what you'd spend on only the rotor housings.

It is reman engine vs new housing. Makes sense. Not sure how I didn't make sense of it before. Sorry
Thanks for sharing. That is a killer deal for all those new parts.

+ i have a "reman" engine in the garage as well, although it hasnt (nor will it) be opened, it looks brand spanking new. ive never seen a brand new engine but this is what id imagine it'd look like. everything is so crispy and all the irons/housing edges are sharp and clean cut

2800 plus your core .. 3800 without core..just emailed ray week or so ago...
Would it be worth it and in my best interest if I bought a reman to tear it down to check and clean out everything

Yes, it would be a worthwhile purchase. If you plan on porting it and changing the seals thsn def break down and rebuild. If you plan on keeping stock ports/seals than I'd say just flush it out real well and plug it in.

the rotor housings are also easy, like the irons they will have new studs, exhaust sleeves will be shiny.
an engine assembled in japan will have the brown japanese tape over all the port openings. the US plant will use those round red plugs

Goodfella for those of us that might buy the reman engines to replace our own, how do we go about removing all that rust without dissasembling the engine?

The new Japanese ones have the same problem for the same reasons. I've torn down many.
Alex, we take them apart for port work etc which makes cleaning easier. I don't have any crazy idea for flushing a built block that you haven't thought of.
Jeff, appreciate the vouch bud
