Everyone says that the sleeves on Honda bottom ends are only good until about 300hp. The only question that i have is, it seems like the vtec turbo engines make a whole lot more power up into the 300+whp range with the same amount of boost that non-vtec engines run on and only seem to make in the 220 - 230whp range...

Now my question about the sleeves is, is it safe for these vtec/turbo engines to be running in the +300whp range with no sleeving due to the way vtec reacts to the same amount of boost? or is it something else?? Because it just cant be "safe" to run like this, right?


Its just something i've been wondering about...
