Ya, they have rev limiters, your shouldnt have even been able to get to 7k. Although since you said you were doing donuts, Id bet you spun a bearing.

 

you spun a bering cheif start shopping for new engines......

 

Unless you got the PCM tuned you shouldn't have been able to go over 6k if even due to the rev limiter. Usually bouncing it a few times won't damage it that bad, never know though. Definitely don't drive it until you get it checked out.

 

BINGO!!!!!!!!!!!!

 

i dont have an auto, but does the rev limiter kick in if the tires are spinning? i had a corolla way back, and on ice i could rev that thing way up, no shifting, no limiter, no nothing.
