If you have any questions about the car please feel free to call and ask. All the bypasses were done correctly and only NAME BRAND parts have been installed. Great time has been spent on restoring the interior and properly modding the engine. It has T-Tops and POSI-TRACTION! The car needs a paint job however I have already begun the body work and half of the car is repaired and restored. You are looking at a heavily modded 1987 Buick Grand National.
I am also open to offers or trades plus cash Trying to put pics up but dont have a photo bucket account.Many more pictures are Available upon request. TT 93 chip, K&N air cone and misc bolt ons. Has 2 nipples but only one is connected.Im thinking im missing a line but dont see anyother lines to plug it into.Īnd my buddy said that the wastegate bosent move when the turbo spools up around 12-14 LBS.Im Lost !!!Īnd is there a way to manually turn down the boost ? I have no scan tools.My GN is all stock except for Walbro fuel pume/ hot wire kit, fuel pressure reg. While working on the vacume lines i noticed two lines that come from the turbo and wastegate.They meet into a Y and turn into one line that goes into a sensor, looks like.Right next to that line is a nipple that has nothing !!! Think its the boost controll. Now my boost is 18-25 LBS.spikes all over the place WOT.Blowing the vacume lines off all over the place.So i zip-tied them all. Thought i had a fule line issue.Turned out to be a ignition module problem.Only 4 cylinders were firing.Replaced the modual with a Bore Warner, but my tach wont read now.So im waiting on the AC Delco modual which is almost $250.
