i have heard he lsvtec has a bad r/s , and can warp the (cylinder?) walls and can snap rods is reved over 6250k. is there any of these problems with the crvtec??

 

The r/s is the same for both setups.
My crvtec just hit 4k miles and has seen over 8k rpms many times.
This has been covered a lot.

 

well, yes the B20's & LS (which are essentially the same engine), do have a rod ratio in comparison to a B16A engine (which is near perfect rod ratio). People don't care though....they want the torque.

But LS and/or B20vtec engines in general, aren't suppose to be rev'd too high because of the powerband. Generally, when you go up in liters the redline drops and this is because you're trading horsepower for more torque. So, a sufficient redline (usually around 8500rpm max) should be respected, in order to keep engine life longevity.
