Harm at 6000 r.p.m.???

your fine even blasting it to the red a few times a day, these things arent made out of pot metal and can take a lot more abuse than that.

Is that not why God invented rev limiters??

My M30 sounds GREAT up in the rev range!!

I often hit the rev limiter in my car - I use the limiter as a "sort of" shiftlight, just as the engine cuts at 6700 or so, change up. It's so easy to do. I have no concerns at all about it. I rebuilt the block two years ago and it's still running sweet. I would suggest before driving at high rpm you know your timing belt (on M20's anyway) is good and your valves are well adjusted and don't rattle. Frequent oil changes are a wise idea. If your engine sounds like a bag full of hammers then fix it first, or one of your pistons may just go airborne!!!

Youre right, but id still like to know that i could rev it if i wanted. Its kinda like the new M5. Alot will be mad that the car is limited to 155mph, even though the car can do 200mph. Most drivers will probably never reach 200 even if the limiter wasnt there, but its nice to know that the car could go 200 if the owner really wanted to.

Removing the speed limit is quite easy. I think not one car in my country has it - it gets removed less than a weak after import.
