initially i wasnt going to do this till later but my 06 wrx has the air pump and what a monster it is, not even sure where i would put it, so while engine is out and everything is easy to get to i mis well reomove it and purchase the delete plates. the only issue is my donar is strickly stock and i want to be able to turn the key and have it start when i get there someday. does anyone know if there would be an issue with this. i dont have an ability to tune out any codes (at least not yet) i am only going to run this car in warm weather so i dont car about cold starts. i guess i can always tune that out later but for know i want to just remove and still be able to start it when that day comes. has anyone done this?TGVs! the tumbler valves on the car are bulky restrictive and heavy. People argue that they help with cold starts but really their main purpose is cold start emissions. Removing them saves a ton of weight, and the accompanying motors/wiring/vent tube really cleans up the top of the motor. Its also good for about 8-15hp depending on who you talk to. This is an easy and pretty much free mod anyone can do at home with a drill and a tap, a few bolts and some grinding equipment. It is well documented.
also, if anyone knows a good website for the blockoff plates please post.
also, i read about grinding off bollts in order to remove, i dont quite understand which ones they are talking about.
any help is appreciated.
thanks,
