I had my N/A motor rebuilt about 9 Years ago and it is still running strong. It has not been driven everyday so I have only put about 30,000 miles on the rebuild.
The rebuild included. New Rotors (89), Resurfaced steel housings and Used Rotor housings. Turbo Oil pressure regulator, 3mm Apex Seals, enlarged oil passage on main bearings and full ballance on all moving parts (including flywheel and pressureplate).
Rebuild was performed by Import Service Center in Winter Haven Florida, just outside Orlando.
BTW, the original engine had 276,000 miles on it when it was rebuilt.

you *** yeah, i had a rebuild last for 6 months (5000 miles) before detonation, then i blew two rebuilds in 2 months due to detonation. no abnormal wear, i put them all together right. Nothing was out of spec, no problem with sideseal clearancing, no endplay problems, no spun bearings, just detonation because i'm a douchebag
SO, i'm doing everything up right this time and this weekend will be my last rebuild (my credit says so) and i finally got a new fuel pump, a 3bar map sensor, and a smaller wastegate spring

Seriously, a proper rebuild should last as long as anything new from the factory. You get what you pay for and care and feeding goes a long way.

nothing makes you cry like popping a motor just after break in... do not take your car to motorsport dynamics in sacramento either, i have seen 2 people blow motors from their shop just after recieving them back from this shop..
my personal rebuild has close to 20k on it now over a period of 9 months and i still have plans on putting it up near the 350RWHP mark and be my DD still, as soon as i can find the time that is! the more mods you do, the shorter the lifespan of the motor will be.

they didn't build his engine but they did try to tune it.
also check the pics of snub disphenoid's supercharger project that went to pieces after he sunk a ton of money into it, all after one of their ex techs had been working on tuning his car.
imo, i don't think they know very much about tuning rotaries. it doesn't take much to rebuild one if one can follow instructions but if you try to tune a rotary to piston engine techniques it won't last long if at all after the tuning process is done.
this all after i spent countless hours working on his car so i have a bit of distaste in my mouth as well.

As a first time rebuilder, I got 3k miles (the first time) because I used 140k mile used housings 
and a suspect rotor (one corner seal was a TIGHT fit). Tore it down after getting 90/70 compression (front/rear).
Rebuilt a second time using 60k mile housing and higher compression 9:4:1 N/A rotors and re-using the same seals as on the previous rebuild (probably wasn't a great idea, due to the Apex seals 'forming' to the "bad" 140k mile previously used housings).
I eventually blew the motor (cracked an apex seal) after getting too boost happy with the hybrid turbo, N/A rotors and lack of tuning.
I'm on the third and "real" rebuild this time... Going back to the 8:5 rotors and upgrading to the R-tek 1.7 chip, FMIC etc... Should be done by the end of the week.

24k on a rebuild from alamo rotary. To be fair, it was my fault it blew. Somthing fell in the intake when I had it off getting the injectors cleaned. The front rotor only had 90 at the time, it turns out. The housings were from an engine of unknown milage and condition ( at least to me). I short, I had been dicked around by protech in austin for 4 months and just wanted a running engine.

Nurse I need 1300cc's NOW
ive had my car for a year and im about to pull the engine for a 3rd time. once when the original engine blew a freeze plug, got a rebuld , and installed the engine with a oil cooler line pinch and stavred the engine of oil (my fault), now the front cover o-ring is believed to be shot. im pissed and im never paying anyone again to do my rebuilds.
