3sgte not boosting enough
|

I have just installed a boost controller and gauge in my celica and it wont boost up to the desired pressure i want. Its a gen 1 3sgte btw.
I have ran a line from a t-piece off the wastegate actuator and i installed the controller in the cabin. Its one of those simple turbosmart ones.
I disconnected that tvsv by blocking off the tubes. It will only boost to round 6psi with the controller closed and 8psi with it fully open. It holds pressure at high revs ok.
Anyone got any ideas?

Well it has a 2.5 inch press bend exhaust which would b bigger than standard, and they boost up to 9psi standard right?
I hav smashed the cat out.... So thats out of the question haha.
engine has done 130000 klms. Turbo should b ok shouldnt it..

that there is a leak in the i/c piping or the i/c itself

was your b/c bought brand new or used?
is is electronic or pneumatic?
if its pneumatic and one of those turbosmart ones, they have a reputation for being unreliable...

its a secondhand turbosmart pneumatic one. I think its ok cos i bleeds of huge amount of air. But im no expert.
If it had a leak in the i/c piping wouldnt it suck in air when its under vacuum?

id put my money on a fudgered turbo or wastegate man, with tvsv disabled u should be looking at 8-9 psi on stock boost....having said that though, when i turn my controller all the way down my guage doesnt show much more than 5psi...but im pretty sure ive got a leak somewhere aswell...cheers

Did you put the T piece on the wastegate line?
I assume the T piece was only for the boost gauge, if so you should have t'd into the line for the map (turbo pressure) sensor.
The boost controller can run directly between the wastegate hoses, no t piece required (just more vacuum hose)

The boost gauge comes off the plenum.
I hav the t-piece between the waste gate hoses. How can i put the boost controller in without a t- piece?

to install a boost control with u need to have it in the wastegate line, with a t piece it is still not doin nethin. one more thing, u cannot CANNOT mount a boostcontol like that in your cabin. it needs to be as close to the turbo as possible. only electronic boost controls can be remotely mounted. pnematic requires the correct pressure to work and at that distance it is getting the wrong signal.
get a piece of hose the right size to go from the actuator to the turbo and cut it in half and put the contoler in there.

u cannot use a t piece, it has a inlet and a outlet so plug it in between the actuator and the turbo.

an inlet and an outlet on the wastegate actuator?
i took of the pipe to the actuator and it boosted up to 14 and hit boost cut. So i guess this means the turbo isnt shagged?
