I took my car to go drive around the block real quick, test the boost, the car at the end started to knock real hard, then about 10 secs later car stopped, i thought it was the battery or alternator but then volatge reading level is fine, the car pulled for about 1 block not running, i turned on the car and the knocking is real bad, drove it back home, the whole car is shaking, not just the engine, but tranny, and exhaust. i also hear something tearing inside the engine, apex seal gave out? Anyways is there other scenario that my motor isn't blown but has like broken engine mounts?, fouled spark plugs?, or drivetrain flywheel clutch problems?

 

wow, knocking is the worst man. probably a 99% chance you have a blown engine. sorry for the bad news. Is it a rebuild or just a low mileage JDM. Cause if it was a JDM then you should have rebuilt it before you ran it, its like the number one rule for new rotories imported from japan.

 

check your oil? look under the hood while the motor is running? could be a belt fraying and whacking the hood/accessory failed.

all else fails: compression check.

why do i find i am repeating myself all the time? no offense but everytime a rotary engine failure is suspect what is always said? compression test.

 

engine was rebuilted about 1k miles ago.

 

You need to do a compression test, there is a how-to on our website. Unfortunately it sounds like you have a blown engine, but the compression will rule that out if it is something else.

 

alrighr compression result with piston tester, i got 0 in the front rotor, and for the rear i got 50, is that even possible? I mean the car can still hold at idle and run,
