I have a 88 supra turbo. When i boost i can hear the turbo and feel it a little but it dies out after like 1 second of boosting. It doesnt hold a boost.what could this be?wastegate?thanks

how high does it boost to? have you checked all of your hoses and clamps?

CHECK ON YOUR CLAMPS LIKE THIS BUDDY SAID...SOMETIME IF YOUR CLAMP LOOSING YOU CAN HAVE TURBO LEAKING TOO...SO CHECK ON YOUR HOSES AND CLAMPS AND ALSO YOUR TURBO BOOST GAUGE TOO.... ONLY IF YOU DIDNT SEE YOUR GAUSE IDLE MOVING AT ALL... :P

i am going to check my clamps and hoses.my meter says im boosting to 6 or 7.

is it auto or standard??

its 5 sp.

my car used to do that when my clutch was slipping. i put in a new clutch and she boosts really hard, esspecially on uphills. does it go to 7, drop to 3(roughly) then 0?

YEA IT BOOST UP FINE.I WAS TOLD IT WAS MY WASTEGATE. DO OYU KNO HOW I CAN CHECK MY WASTEGATE?IF IT IS THAT?THANKS

wastegate or the wastegate solenoid? my friend told me that its more likely to be the solenoid that controls the boost. it should be by the driver side strut under the hood.

OK THANKS IM GUNNA CHECK.
