I'm thinking about getting a rx-7 with a mazda reman motor. I just want to hear some experiences with these. How many miles do they usually get before the die or need a rebuild. Also what problems have people had with these, or are they pretty much as good as new?

Thanks,
Josh

 

i have a stock mazda reman. completely happy. about 40k on the engine over the past 4 years.

make SURE u pick a reliable and trusted shop to install the motor.

a few years ago there was a problem with remans failing, not sure what the problem was.

 

The job was down over at Rotary Extreme, they're pretty reputable from what I've read.

 

chuck is the man, hes extremely good at what he does

 

ive bought lots of stuff from chuck and he has always worked with me on problems and questions about his products. im sure its going to be a happy purchase.

EDIT: what car are u buying btw?

Is the one. I'm just sure about getting something with a reman motor. Originally I wanted something with low stock miles.

 

u do not want low stock miles over a reman on an engine....

that would be over 11 years old now? low miles would mean the chassis is in better shape though.

EDIT: O SNAP! thats the car i would have bought if it was for sale 4 years ago haha.


talk to the owner though, i heard it had a coolant leak? not sure about that, ask around.

 

I've heard varying reports on the quality. What specs do mazda meet when they reman the engine?

 

mazda itself doesn't reman the motors. at least until a while ago it was a company in florida that builds them for mazda, not sure if it's still the same company

my FD has a reman in it. as far as i know, they're fine as they are if you run a pretty stock setup. they come with mazda warranty as well, for 1 year i believe. if you put on a good number of mods, attentions need to be paid just as you would with any other original factory motor

 

As noted, Mazda contracts out the work for the engine builds. However, the specs that are used for the motors are the same specs every rebuilder uses (as Mazda did create the specs in the first place). The question is not the specs; the question is are the specs followed.

I ran a reman for about 4.5 years. It blew it last year, but it was on the track not street driving. The reports over the last year had been very good about the remans. A lot of them were coming out with a new housings in them.

 

i have a reman i have a little noise out of it once in a while but i think its mostly do by the exg. leak that i have but its about to get fixed so i'll see if the noise percess

 

Why?

 

So? My '94 has 29K original miles and how does 11 years make any difference in the condition of the engine???

 

because the longer oil touches or has not touched plastic, rubber, gaskets, whatever, and the longer water sits in the engine it is always going to be in subpar condition when comparing an 11 year old engine and a new reman. common sense says oil leaks are more likely to occur on an engine that is older and has used gaskets than a new one. this is why people dont usually put a used JDM engine and opt for the reman. sure, there is less availabilty now, but its pretty agreed upon that putting a used rotary engine, even one with low miles is not the better option.

if your a car collector, of course thats different as you would do things to keep the car pristine, such as additives, keeping the car garaged, etc. but then your never really going to drive the thing anyway and little paint chips give you ulcers.

i would have thought the king of speed would have clocked more than 29k miles... if those are mostly track miles, then hail to the king! ha. i have not tracked my car, but perhaps someday soon.

anyway, im not trying to rag on your nice stock cars with low miles, but the point of owning an FD is to drive it. at least in my opinion. and it demands to be driven hard. it is one of the 3 japanese super cars afterall.

 

Blah, blah, blah...nothing wrong AT ALL w/ a low mileage car. And engines, regardless of age, eventually lose compression due to the wear and tear of high mileage, NOT low.

I have more than one car. Then again, what's it to you how many miles I drive every year???

My FD gets driven approximately 216.66 miles every month.

Tell that to the cop the next time you get pulled over.

 

I have had a Malloy reman for 3 years now with 20K+ miles. Installed it my self, ran it with stock turbos at 15psi and 345whp for the first two years. Pulled it, installed a single turbo and fuel upgrade, now running at 400 to the wheel at 20psi for nearly a year. Still seems to hold up quite well.

 

Sounds like the remans are pretty good. Haven't heard bad anything in particular other then one guy who's gone through a bunch of them.
