DIY: Porting & Polishing a Throttle Body. In order to do this procedure, you must remove the throttle body from the engine so you can probably polish and port the throttle body and the material shavings do not enter the engine. This is a very small horsepower increase depending on the design of your engine, but it will improve throttle response and reduce the amount of oily residue build up. Do not remove any material from around where the throttle plate touches in the bore either. Also when doing this procedure, I would recommend purchasing a new throttle body gasket so you won't have any vacuum leaks once reinstalling. This particular tutorial was done on a 1. BMW 5. 40i.

Because I'm using the '05 R head, I should be using the '05 R head gasket, and the Cometic is a match, so that's ok. What puzzles me is why Honda went to the thicker. Facebook: https: //www.

Tools/Supplies Needed: -socket set and ratchet- throttle body cleaner- lint free clothes- new replacement throttle body gasket- tape- rotary grinding stones- penetrating oil- Dremel/rotary tool- flap wheel drum sanders ranging from 4. Procedure: -first remove the throttle body from the vehicle- removal processes will vary between manufacturers, but normally it is bolted to the intake manifold, the throttle cable will need to be disconnected it a manual unit, and then unplugging the throttle position sensor- clean any oily build- up inside of the throttle body- remove the butterfly from the throttle body, most are held in with two screws that go into the shaft- if you can, also remove the shaft and linkage- tape around the shaft or the hole where the shaft was so no metal shavings get into that area and cause premature wear for the bushings or bearings- depending on the finish of the throttle body's bore, there may be edges which you can to smooth out- in order to smooth out those edges, you can use grinding stones for either a drill or rotary tool such as a Dremel- when using a grinding stone, its best to use WD- 4. Scotch Brite - depending on the color, will depending on how course the abrasive pad material is- I started out with green and then moved onto the red pad for the finest compound- you can also use water with this too to help finer sanding and to keep the dust down- again once you are satisfied, you can now move onto a metal polishing compound- the metal polishing compound I would recommend is Eagle One- apply the polishing compound paste and rub until highly mirrored finish - multiple coats can be applied to achieve a higher polished surface- once you are done with the bore, you can now move onto the throttle plate- most throttle plates are smooth to begin with so you can skip directly to the Scotch Brite stage using the same procedure and finally move onto the metal polishing compound- once done, you are ready to reassemble the throttle body- make sure you peen the thread of the screws on the other side to ensure they don't come out or apply Lock Tight thread sealant- install new throttle body gasket along with throttle body to your vehicle- assembly in reverse of disassembly.
