1 TDO4 compressor housing oring
upgraded 14mm thrust collar and 14mm thrust spacer
6 oil / coolant feed orings
1 oil drain oring

This rebuild kit provides durability above 22 psi. The upgraded thrust bearing, collar, and spacer are essential for the longevity of your turbo rebuild. Other similar products often have too small of oil holes causing lack of cooling resulting in failure.
The MMP turbos use a TDO4 compressor housing o-ring because it uses TDO4 compressor housings. Most TDO4 N54 turbos do not use TDO4 compressor housing, which is why this kit is specifically created for the MMP journal bearing turbo chargers. This rebuild kit in summary is an upgraded TDO4 rebuild kit that includes o-rings and 1 gasket for the oil and coolant lines included. This rebuild kit is not for MMP ball bearing turbochargers, please view our other listings.
Additional notes: the MMP journal bearing turbos use a 19T billet 11 blade compressor wheel measuring 46.02mm x 58mm and a TDO4HL 45.6mm x 52mm 9 blade turbine.
