I know of geof, and im not saying go against the mans recommendations. But you ave to realize something when talking to him, hes a full drag strip racer by heart. He will always recommend the bigger turbo because to him more lag and higher hp is acceptable. But anyways, a little update. I just got my 250 mile oil changed and there was no metal fragments or shavings in, which is excellent news. The motor is getting louder, the builder told me its because my rings are getting seated and are the pistons oversized so they will produce more noise then stock. I have to get another oil change in 300 miles, and after that my motor is almost half way to being broken in.
