Page 24: Port & Polish of Throttle body. Throttle body was taken from a Y32SE Motor which is 3.2L but its identical to the 3.0LSummary:These engines are produced in mass quanitites, and often the attention to detail is... :confused: not that great. To my surprise the build quality of our engine the X30XE is quite good, and everything fits perfectly but there is always room for some more. The parts I got are Y32SE Throttle body, and Intake manifold, combined with 3.2L Fuel injectors. The throttle body has around 50K miles on it and as you can tell the EGR system sure got it dirty!Each of the throttle plates, as you can see there is quite a bit of room to remove material from the center bar and free up some flow. Here is the 1st stage of porting, I took 150grit sand paper, and a dremmel and sanded off the edge found inside the throttle body, I also opened up the front part so now its a smooth bore all the way to the narrowest part. Next up, I need to clean both TB openings and move to a 600grit for a finer finish, and then finish it off with 1000grit.As a finishing touch, I used some aluminium polish to get it to shine, but I dont have pics of that.
