Darrin_b Posted August 13, 2014 Report Share Posted August 13, 2014 So I had a bad 12a turbo it was seized when I got it I put a rebuild in it (new bearings, seals etc.) I have a 1g bov hooked up to it and a cheap Manuel boost controller along with aftermarket gauge I was running 11psi of boost it worked and ran fantastic pulled hard was doing great then last night (3 days after I rebuilt it) I was racing around and did a burnout I saw my gauge during the burnout it was 9psi then got down to the next stop sign and then started going and my car wouldn't boost it got to -1psi and made a weird deep turbo noise and was like "wowowow" like a howling woosh I thought great I just fried my turbo I drive it home easy and tore into my turbo got the insides out it looked fine the turbine spins free sounds fine feels fine and has a tiny bit of side to side play but it was like that when I rebuilt it to I checked my intake and exhaust housing they looked fine I put it back together took it down the road and it did the same thing I'm lost now what do I do?!!!!

scott87star Posted August 13, 2014 Report Share Posted August 13, 2014 Look for the hose that blew off, it may be quite small (vacuum line) or it may be one of the intercooler hoses. Quote Link to comment Share on other sites More sharing options...
Darrin_b Posted August 14, 2014 Author Report Share Posted August 14, 2014 I made sure everything is on correctly and tight Quote Link to comment Share on other sites More sharing options...
Guest 87redstar Posted August 29, 2014 Report Share Posted August 29, 2014 Is the wastegate arm attached to the flapper. Safety pins work in that hole if you dont have a cotter pin Quote Link to comment Share on other sites More sharing options...
importwarrior Posted August 29, 2014 Report Share Posted August 29, 2014 paper clips work also. sounds like the flapper is not moving or staying open because the waste gate arm is detached. Quote Link to comment Share on other sites More sharing options...
