i just finished putting my turbo on my car today. i turned the car on to check for any leaks or whatever and everything was just fine. i looked at my boost gauge and it read zero. i thought the boost gauge was bad but i put in on a vacuum line behind the manifold and it read fine. what i did was that i did a T-fitting on the tip thats on the side of the wastegate to the turbo and then to the boost gauge. thats where i reads zero. when i take the vacuum line off of the turbo, there was no pressure coming out. well, the vacuum tip is not exactly on the turbo housing but it is on one of the piping that goes to the turbo housing. is that the reason why i have no pressure coming out? could my wastegate be bad? any suggestions guys.

 

did u actually drive? rev? thats how u make + boost.

 

yes, i drove it around the block and it feels like a normal car. didnt feel anything or see anything. no + boost and i rev it to 5000 rpm and still didnt see anything.

 

bad boost gauge.
car runs feels like no BOOST!!!!??

 

is your turbo spinning? you either have a really bad turbo or a really big exhaust leak between the head and the turbo. what kind of turbo is it? what manifold? what wastegate? did you run oil lines to the turbo? you need to post more info. your boost gauge vacume source should be the intake manifold.

 

Go through all your intercooler piping.

 

that too

 

give me your car............!!!

 

i checked everything yesterday and i have a leak somewhere on the downpipe. not through where the downpipe bolts on but theres probably a crack on it. also one of my intercooler piping came off by i fixed that. it boosts now but i cannot full throttle it. i guess i need tuning. anybody knows who has a dyno that tunes hondata?

 

oh yeah, y u want my car, its just an accord jdm civic.
