If the car is not wrecked, most likeley the motor already needs to be rebuilt.

We can't answer that question for you. There are a lot of factors that need to be addresed (answered) adn it will take you a day to research what needs to be answered and then another day to go out to the junkyard and perform the test needed. Once all this is done come back and post the results. We'll all pul something out of our butt and fling it at you in the form of an answer

big question is how much do they want for it. Also if you don't want to mess with rebuilds it might be a good idea not to get a rotary.

no dont want to mess with rebuild for a while only a money issue not mechanical ability. they want a grand for it but i think i can get the harness and all. I am going to comp test it as good as i can cold but i dont really know the average life of a turbo 13b. I also want to check shaft play and alot of other stuff i was just wondering if theu usually go between 100k-120k. I am looking for a used one just because its cheaper than rebuilding mine ( two thrashed rotors and housing, bad bearing)

You can buy a complete car for a grand!! Maybe even running! Sure is a lotta work for a junkyard motor. The motor alone should only be about $300 from a J/Y

ok you are wanting to buy a car out of a junkyard and want it to be reliable? If you want a turbo charged car on a budget i would not suggest you get a t2.

Check compression if possible, that'll give you a good indication right there.

A TII motor can last anywhere between 100 and 200k miles depending on how it's treated along the way. It's impossible to say unless you know the history for it. I believe the average lifespan of a TII motor is around 150-160k miles, but I have a friend, for example, with a TII with original motor that has over 180k miles. So who knows? We have no idea what condition the engine is in.

For a grand, get a J-spec with a warranty/guarantee. J-spec providers are probably a little better than A-spec j/y providers.

^^^thats true as well (THeres alot of talk on how cheap parts and motors are but ...)

The j/y is not a bad idea but I think a grand is a little steep. you should look for a blown motor and rebuild it. There are a lot of Short blocks that pop up in the F/S section that have good rotors and stuff.

Your in a hard spot.

i would go to the junk yard and see if you can take a compression test on it.. then come back with the results.. also 1000 is too much for a motor in a junkyard...(once at my local junk yard they had a GSLSE running motor with 150k miles and im like how much and is like thouse rotarys are gold and said 1400 and i just laughed at him lol)

Any 13BT engine getting close to 100k miles will have worn apex seals, regardless of the compression.

If I remember correctly, 8.0mm is brand new spec height of Mazda OEM apex seals.
7.0mm to 7.5mm height require changing apex seal springs.
Under 7.0mm, Mazda recommends to REPLACE the apex seals.

I would recommend a rebuild SOON.

If you do go for this engine and the compression checks out good, it should last 20k miles *IF YOU DO NOT MAKE MORE POWER*.
So, at stock power levels, it should go 20k to 30k miles no problem.
Hell, it should hit 150k miles with relative ease.

Once you start to mod it (i.e. freer flowing exhaust), all bets are off.
The higher power levels stresses the already thin apex seals, and there's a good chance the apex seals will fail.

I would really watch buying a jspec engine. I just got a royal fu@#ing on one. $1411.00 delivered and the irons and rotor chambers are junk. Full of water. Be careful!!
