SHIEF Posted February 22, 2005 Report Share Posted February 22, 2005 If anyone is available and knows a little bit about turbos I need some help (my friends are all too busy I guess). Having boost probs with my new to me 85 200sx turbo. Good turbo, just won't build boost. If anyone can swing out I'll buy you some beer or whatever. Have heat and light. In Pataksala, on 40 (main st.) just before SR 310 (past Mink Rd.) Address: 11091 National Rd. SW Pataskala, OH 43062 Quote Link to comment Share on other sites More sharing options...
Alex1647545498 Posted February 22, 2005 Report Share Posted February 22, 2005 Can't help. Got to work in the morning. Check for vaccum leaks/pipe leaks and your bov might be stuck open. Quote Link to comment Share on other sites More sharing options...
SHIEF Posted February 22, 2005 Author Report Share Posted February 22, 2005 Car doesn't have a bov. I've been checking shit all night. We'll see, thanks. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted February 22, 2005 Report Share Posted February 22, 2005 won't make boost at all or only like 5 pounds.... if its been sitting the wastegate could be froze open.... Quote Link to comment Share on other sites More sharing options...
SHIEF Posted February 22, 2005 Author Report Share Posted February 22, 2005 Makes like 1 or 2 pounds. Anyway to make the wastegate 'unfreeze'? If there's not then I'll replace it tomorrow. Funny you should say that Dave, because that's the last thing I'm down to. If that's not it then the 'good turbo' is not good. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted February 23, 2005 Report Share Posted February 23, 2005 take it off and see if the actuator leaks or is rusted/stuck you might be able to hit it with some pb and get it workin Quote Link to comment Share on other sites More sharing options...
Berto Posted February 23, 2005 Report Share Posted February 23, 2005 you can put a rubber vaccum niple on the wastegate actuator. use a hand pump with a pressure gauge, carefully puncture the nipple and press around the needle and pump it up to say....10 psi see if you see the actuator arm move. if not u can try to build a pressure testing system for your setup and see if you have any major boost leaks, i have pictures and stuff of my set up for testing for boost leaks if you want them.

SHIEF Posted February 23, 2005 Author Report Share Posted February 23, 2005 I'll test that stuff tonight on the wastegate. I'll let you know Berto if I need those pics. Thanks Quote Link to comment Share on other sites More sharing options...
SHIEF Posted February 23, 2005 Author Report Share Posted February 23, 2005 Got it figured out (hopefully). Wastegate is opening WAY to soon. Gotta get some kind of boost controller. Plus timing was advanced 10 degress, causing a slight detonation, which causes the det sensor to retard the timing 10 more degrees. Anyway, thanks for the info.
