There is no boost controller in the supra, just a turbo timer. It looks like its been there a long time too. The angle of the picture is from the passenger side looking into engine bay. Right on top. Ive never seen where a boost controller was ever used on the car but i guess it is possible. What should i do with it now since i dont have one? Has this damaged anything?charleshmlee said:That is a vaccum bypass because you have a boost controller in your Supra.
Ok i did that! thanks for looking. Also, did you notice the oil all around that thing and dripping on the turbo sheild? That cant be good coming from the rear turbo blower side!SteelCitySupra said:I dont know why that would be done like that... if you want to "pull the hoses", that isnt the way you do it on a TT supra (to run as much boost as possible)... I would just connect it back the way it is supposed to be. The left vacumn to the left nipple and the right to the right... ect.
Take a picture as well for this. Not sure if your talking about the wastegate or thekilobit said:I just noticed something else. The same thing was done on the front turbo as well. I never noticed it before but i just replaced the timing and had everything off the car and then i saw the exact same thing on the front. Why would they do both that way? The car drives good and then has a alot of boost topend. With the rear turbo back the way it should be its definatley more smooth of a transition and you dont feel as much top end on it now. Should i fix the front back to the way it should be?
