Just like the title says... Where's the best place to pick up a NEW motor...? S5TURBO

(Please don't tell me to search... because I'm getting this: The following words are either very common, too long, or too short and were not included in your search: New
So yea, after already spending my time reading three pages I still need a answer to this question.)

I remember reading some negative replies/topics in the past about certian companies, (whom I don't want to mention in case I'm wrong) but where's the best place to order myself a new block.

I'm going to be dropping the $$$ this week and I'm ready to buy so any advice would be appreciated, espically from those who've recently been downb the same path.

When you say "new" block are you asking about a crate motor brand new from Mazda or a rebuild???

Well I called the local MAZDA dealership here in NY and the prices I got were 2900 without a core and 2300 with a core for a 1990 Turbo motor. Mazda no longer sells NEW engines I was told and these are factory rebuilds. The wait would be a week to get it in so I would assume they are not making them at this particular dealership.

Sorry about that... by NEW I guess I meant MOST reputable.

Mazda is by far the most reputable. Can't go wrong with a Mazda rebuild in most cases.

Now, if you want porting and other services, you will have to find a rotary specialist. I hesitate to recommend anyone in particular, simply because my bias is VERY strong.

jhammons01

Mazdarx7.com has those Mazda rebuilts for a better price. Your freight will kill ya. All the way from San Diego area to NY.

My local Mazda dealer won't rebuild at all. They are afraid of the rotary. they just do Mazda rebuild swaps.

The builders out there all seem to be at the same price so If I were to pick I guess I would go with the Mazda. I chose to rebuild mine at home.

i just swaped my engine out this winter for a fresh ported one from chris at banzai racing if you have a good core he can rebuiild it for around $1500 with no extras i'd say. the highest price would be 1800. as long as you don't have any damaged parts and he will provide you with a full phote documentation of the tear down and rebuild if you want it. shipping would run between 250-400 hundread depending on who you use to ship. ups ground would probable have the lowest rates.

chinook527

I just swapped in a Atkins rebuild for my 88TII. 1800 and 300 for a stage three street port. So far I am very happy after 1000 miles. It came with every gasket necessary. Im not sure if they are the best, but I am happy with it. BTW they do rotaries for aircraft, so they stress reliability.

gerbraldy

get a rebuild, do not buy a jdm enigine. who knows how long its been sitting without oil.

jhammons01

^^^ Screw those JDMs they all have "30-40K" on them......yea right. They also seem to have a disclaimer that they are readily rebuildable japanes motors. Well OK I can get you are redily rebuildable motor for free.......its sitting in your engine bay right now.

Nor does anyone else. To assemble a completely new shortblock from all new parts would cost around $5000-6000 with today's housing prices.

To my knowledge, no dealerships anywhere do their own rebuilds. IF you need an engine, and you opt to allow them to do the work, they call in and get a reman sent in from the national facility. They swap it into your car and return the core left over back to them.


You guys do know that mazda doesnt do their own rebuilds, right? Last I heard, they subcontracted the work out to some company under caterpillar, but don't quote me on that. Mazda just supplies the parts. It's not totally uncommon, as with any rebuild from any source, to get a bad engine or have a questionable part be used. I see posts every once in a while in the FD section about a reman letting a seal go in just a few hundred miles, or having a leaky coolant seal from the beginning. The FD guys love remans from malloy, since FD internals are harder to find and more expensive, so when they do massive damage it's often easier to buy a reman for 2 grand (the cost of just 2 rotors and 2 rotorhousings) and then build from/modify that to suit their needs. So for this reason you see a lot of FD guys getting remans consistently, and of course that increases the chances of seeing bad ones pop up.

...towards doing it yourself, I assume?

Years ago on one of the mailing lists, I remember reading a post from someone who had actually toured the Mazda rebuild factory. Let me see if I can find it....

...found it:

From: Marcus B. Fitzhugh

Subject: Re: Mazda rebuilt engines?

I asked to interview a manager and spend a few hours at the Irvine
California R&D center for an article on factory remanufactured
engines. I was told Mazda no longer rebuilds engines in Irvine.
Delco Remy has the remanufacturing contract and they do all the
work. All of the following miscellaneous ramblings about Mazda
remanufactured engines were correct as of October 2003.

When you buy a Mazda remanufactured engine no parts from an original
engine are specifically assembled to build another engine. When a
core comes in, all parts are spec'd, cleaned, and shelved. No
special engines (such as TII rotor housings on an NA, or Renesis
rotors in an S5 block) are available. Shelved parts are picked at
random for reuse during assembly of a remanufactured block. Out of
spec side housings are shipped to Japan to be lapped and re-nitrided.
Mazda only uses 1 lapped side housing in any remanufactured rotary
engine. Some engine builders boast that they lap all the side
housings, but do they re-nitride them as well? Hmmm. . . . . An
engine with a lapped side housing is scribed, and it is noted on the
build sheet. Customers never see build sheets as they are kept by
Mazda. The build sheet has a list of all the new parts that were used
on the engine, test results and the compression numbers. The build
sheet matches the serial number on the front of the block. Pry that
serial number off, and your warrantee is void. Rotor housings? Any
rotor housing that is out of spec is tossed. Mazda does not
remanufacture rotor housings. Some Mazda remanufactured engines have
two used rotor housings and rotors, some may come with both new
housings, and used rotors, some with new rotors and new housings, or
any combination you can think of. It all depends what is available
when the engine is assembled. Side seals on the rotor are custom
fit. These are custom seals in varying lengths that Mazda does not
sell to the public. Completed engines are run on a test stand and the
results are checked by machine. Engine vibration, oil consumption,
and a number of other things are noted on the build sheet. The
engines are run using a carburetor. The compression checks that are
done are not performed with the $1500 tester that dealers used to
have. Any remanufactured engine that does not meet spec is
disassembled and whatever is wrong is corrected. All engines are
shipped with a new/Mazda-rebuilt water pump, oil pump, flywheel, and
new exhaust studs are used. OK, that's enough for now.

As for the dealer that told you they could supply a Mazda
remanufactured engine for $1400, the price hasn't been that low for
ages. The counter person was probably speaking off the cuff. The
current retail price is closer to $2200 plus a core charge

If someone were to run an article on Mazda remanufactured engines,
would a large number of you read it? Roundel readers found this type
of thing interesting.

Towards finding a reliable, local builder who comes highly recommended from several people who have put some decent mileage onto their engines. Or, if the person has the talent, to do it themselves.

Mazda remans are now done by a company that is owned by AC-Delco. The work is performed in a plant off I-26 in Summerville SC

Do you know if they follow the same procedure?

Mazda's west coast reman facility is no longer open, from what I'm told. IT was rumored that quite a few poorly assembled remans came out of that facility once the employees found out it was being closed.

i should go down there this weekend and check that place out sounds real neat

Good Luck, its completely fenced in with a guard at the gate
