I spoke to Rotor Sports today, and discussed what's happening to the car. They are rebuilding it and then some. They are putting in an ACT heavy duty clutch, a new flywheel, and stronger apex seals which they have used in the past on many turbo'd applications, as well as a wideband for propper dyno tuning. I hope all the problems I endured with the local shop and them killing my car only was a blessing in disguise, b/c I feel that my car will run better than ever within a few weeks!

you mean they are installing a 2nd wideband. which apex seals are they using and do they need to machine the grooves for them to fit?

OfficerFarva

I am not sure what the name of the apex seals are, but i know they have to machine the grooves so they fit. If u hadn't asked me the name of the seals i probably coulda told ya .

How much are they charging you for the rebuild?

OfficerFarva

I can't really discuss the cost for everything yet b/c my situation is pretty tender right now with the guys who killed the car. So I don't wanna throw anything out there that might be incorrect or is subject to change right now.

rkostolni

OK, then I'll ask, does anyone in general know how much it costs to rebuild a rotary. I'm just curious in the event that my engine decides to chew up its seals.

OfficerFarva

well i know a new engine is generally between $2400 and $3400. A rebuild i think would be around $1900, but don't quote me on that.

That's a hard question to answer. It really all depends on how much is usable. If a seal goes, it takes out most of the engine with it. If no housings needed replacing at all and all you needed were seals, it would still cost you around $1000. Tha's not including any labor. If you need rotor housings, rotors, etc. the cost will go up.

How much labor is involved in the rebuild? Seems like $1000 + labor could rapidly approach buying a used engine + labor.

And congrats on your good luck so far O-F.

If you were to purchase the parts alone for a brand new engine, it would set you back somewhere around $5500. You can get a used engine for around $2500. The question is do you want to just install that engine and assume it will last long or do you want to go ahead and rebuild it? If you do rebuild it, you will automatically need to spend some money in parts to put it back together. What if you see some parts that are out of spec and "should" be replaced? Do you spend more money and replace them or just put it all back together with new seals? Luckily most used engines should be quite usable since they should all be fairly low mileage.

I was told by my Mazda dealer that a brand new motor is only $3k, and someone on here, I think its Thew has them for $2500. Really makes the most sense just to buy a new engine then.

rotarygod

I have only seen used engines at $2500. If I could find a new one for that price, I'd buy one tomorrow just to have.

OfficerFarva

Rotary God, do you think the bigger Apex seals make more sense for the turbo? I have also heard that b/c they are bigger that they will not do as "well" as the smaller oem renesis ones at higher rpm. Any truth to that? I know the guys at Rotor Sports know there stuff, and feel that since these seals are stronger and they have personal experiences with them on 3rd gen 7's that they will only benefit me for having a turbo now.

You are almost right. Is a Reman motor but pretty much new. http://www.finishlineperformance.com...ine_index.html

reman motors are not pretty much new. I have seen quite a few in the older fc's and such and they did not have near the longevity of a new factory motor ime. One is built in Japan and one built at a motor assembly plant in the states. The reman's mazda dealers sell come from the place in the states atleast.

The price on the link below is $2499, but when you click on the engine it changes to $3499 ($1000 extra core charge). It would seem you are better off buying new.
