Hi i am a new memeber of this forum, as well as a supra owner. I purchased a N/A auto mkiii which was converted to a manual w/ 7mgte and R154. THe previous owner cut many corners during his install and did a shitty job. He got rid of the charcoal canister and im not sure to just buy one or can I run w/out any problems without it? Also, I bought a used 7mgte (from canada) and noticed that the small hardlines which attach to the upper intakle plenum has different numbers of lines. Im totally confused. Also does anyone know what the little regulator function is that is located below the turbo to the right of the motor mount? I have put alot of time and late nights looking for answers all over but am coming up short. But I really enjoy learning about this wonderful machine. Thanks for any feedback!
