I have decided on building a turbo lsvtec. My plan is to install the engine already built for turbo and then put the turbo together and install later. JE pistons and Eagle connecting rods are on the parts list but im wondering about sleeving. Forged pistons and connecting rods would be safe at 15psi right? and of course if I wanted say 30psi it would no question need to be sleeved. I would not be hitting the boost all the time, more like on occasion. This car would be used as a some what daily driven car with trip to the drag strip every now and then. 15psi sounds about right for me power wise but would sleeving make it alot even safer or is that only needed when wanting a lot more power? Another question I have is how much horsepower is "streetable"? a little more then 300hp is my goal. Would this number be safe with only forged pistons, connecting rods, a well built engine, and a good tune?
