Thanks for the reply. Here a pic of my BV206 on the Pemberton Icecap where I blew the turbo. Let me know how the drilled out injectors work. I was talking to Metric Motors and they said the weak link on the engines was the con rods and the head sealing and might not hold up to to much increase in power. The BV206 ops man says the 617 puts out 125HP at 4350 RPM which I think is quite a bit more than the 300TD series states. I think the only difference between the two might be the cam.
