10lbs on vacuum?

abhattan · 04-19-2007, 10:25 PM

I've heard of a way to run about 10 lbs of boost without a boost controller or without shimming the wastegate. It is said to be done by rerouting the vacuum lines, but I am not sure to where. Does anyone know anything about this. I just want to do it until I get my EVC in about a month. Stock boost isn't cutting it for me anymore.

I have no clue how to do that nor have I heard of a way. But shimming the wastegate takes like 5 mins to do. It's so easy and cheap it's ridiculous.

Don't I have to take of the exhaust off the back of the turbo? Expalin!

Just buy some washers, take off the intercooler pipe connecting to the 3000 pipe, remove the accordian hose, take the bolts out of the wastegate, pull the wastegate towards the front of the car. You might need a little strength to hold it open, it's not easy to do both at once. Put the washers in between the turbo and the wastegate, put the bolts back in and hook everything back up and you're good to go. That picture had the boost set to about 10-11 psi.

manual boost controller,

connect the hoses, ziptie the controller somewhere and ur done

all you have to do is set it at the right boost

I don't know about how strong a stock Supra turbo motor is when you get crazy stupid with cranking up the boost with a manual boost controller, but don't do what i did with my Eclipse. It was running pretty good until an old coworker of mine had the stupid idea of making a ghetto boost controller out of a piece of vacuum line connector, with a small hole drilled into it to force the waste gate to open later. Needless to say, i was running about 16 lbs of boost on a stock motor and nearly popped it. That's why it's been sitting in my garage for about a year and has been sidelined for at least the past two. I wore the rings out. It was eating about a quart or two of oil a week. I'll bet i won't do that again.
