turbo choice for new build

Post by RosadoRacing »

My oil pump shattered an destroyed my turbo due to loss of pressure. I turned it off just in time to save the motor but the 6265 didn't make it. Now I'm doing a rebuild and thinking about buying a bc crank, pauter rods, l19 bolts to attempt to break 800whp. My options are 6266 or 6766. My only concern are my eagle rods the rest of my build will hold 800whp since i will be installing arias wrist pin upgrades. Tell me what ya think. When would a 6766 see full boost? I was seeing full boost with the 6265 .68 right around 5k

Well the 6765 has proven 800whp on 39psi full spool around 5500 so the 6766 should perform similar if not better than the 6765.
