Rotary Extreme RX7 Build Day 14 Wastegate Port
I cleaned the turbo actuators, sanded out some scratches on the pri turbo wastegate actuator (picture shown is not finished with sanding), used the eagle one again to remove some corrosion. It cleaned up the charge relief actuator pretty good. I also pulled off the oil pipe on the engine too.
The other thing I did was port the pri turbo wastegate to 1.22 inch or 31mm. I used my ebay bits !!!. I used my scribe to outline how far to port and I also drew a line around the edge of the port to make sure that when the gate is closed that I cant not see the sharpie mark. I happy with how it came out. The silver sharpie shows just how small the overlap is now.
