I have a 93 civic hatch si with a d16z6, I just installed a greddy 15g turbo internally waste gated. When I rev it up or drive it around the turbo dosnt spool up no does the bov make any noise. I know this turbo is super loud and the bov i have is loud as hell also ( greddy type s 0, But I dont know what the hell is going on. I need some major help.

 

check all your chargepipes. It can be a leak!

 

turbo not spooling?
Check your wastegate

 

what size down pipe/exhaust are you using? do you have your stock cat in?

 

read the other post in this forum.

 

Im using 2.25in mandrel bends for charge pipe and i have a greddy down pipe. i will try checking for leaks, but where should i check? I also would like to know how to adjust the waste gate so it pushes more boost out, maybe its set to low.

 

If the actuator is working properly then you will see at least 6 to 7 pounds of boost. most come stock actuated at 8 to 10 pounds. check for leaks using soap and water. again all of this is covered in the other post so I am not going to waste my time writting it all over again as my chemisty lab starts in 17 minutes.

 

i had the same problem on my 14b setup. what to you have for a filter on the intake of your turbo?
