turbo wont boost
 

i have a 89 supra turbo and i can boost more than 8 psi. i chime the waste gate to gain my boost. i was at 3 washers and i was getting 8 psi. i went to 4 washers and i still get the same result. is it possible that i have a leak?? if so any idea which hose it can be???

do you have a boost contoller on it?

no. i chime the waste gate to gain boost.

There's definitely the possibility of a boost leak, unfortunately ANY hose can be a suspect hose. Just idle the car and listen around the engine bay, if you hear any air being sucked in besides at the air filter, there's a vacuum/boost leak.

You should really do away with the wastegate shims. Although it's easy and cheap, you put more stress on your wastegate. You can build a MBC easily (and more importantly, cheaply). That way you can adjust your boost as needed without unnecessarily adding more stress to other components.
