3sgte swap heat soaking problem, Thinking mod intake manifold Options

[Caifan68]

Hey I have a 3sgte 3rd gen on my Celica but I have a problem that's is not boosting stock psi is on 7-8 psi n I see that it might be cause the piping that is close or top of the exhaust manifold gets super hot n what I found online that soaking heat don't let the car get full boost. When the weather is really cold I can get close to 10 psi so what I'm thinking that that's my problem the soaking heat so I wanna see if I can use any other intake manifold ? I was thinking to do a custom on or see if that one on the 4th gen will fit. N hoping to find help here I'm new using forums n im in SoCal if someone close can help me get my car running 100%

You probably have a boost leak. Or if your check engine light is on your car is in limp mode

How can I check that ? N so u don't think that is cause of the soaking heat ?

You can spray carb cleaner over your vacuum lines while the car is idling. if the idle jumps up then you have a vacuum leak,which can also be a boost leak when under power. also if your check engine light is on it will be in limp mode like enderswift said.
