8 new 12 point bolts for the outlet housing
Includes additional compressor housing o-ring
4 inch turbo inlet hose and clamp

NOTE: Garrett's PARTS LIST included has a typographical error stating that it includes a V-BAND clamp when in reality it is the flat band clamp for the inlet hose at the turbo.
Garrett also has included a new turbo outlet o-ring but it is for the GTP-38 Early 99 turbo and will not fit this turbo. I will include the correct turbo outlet o-ring with every turbo at no additional charge.

Overboost Regulator 
When upgrading your turbocharger to the Garrett Ball Bearing turbo, your intake system will have the capability to develop boost pressures in excess of what the computer is expecting. This will cause the PCM to open the wastegate prematurely, defueling the engine. The purpose of the overboost regulator is to regulate the boost pressure read by the MAP sensor. Overboosting can set an "overboost code" that sets the Service Engine Soon light and will cause the PCM to defuel the system when is reports pressures of 23 psi or more
