this is an upgraded TFO35 turbo rebuild kit for the stock Nissan Titan low pressure turbo.
This rebuild kit has TFO35 journal bearing which has a smaller inside diameter to match the TFO35 turbine shaft in comparison to the TDO4 journal bearings that are larger to match TDO4 upgraded shafts
If your turbos are upgraded the turbo likely uses a TDO4 superback rebuild kit
This kit has a dual oil port machined from cooper bar upgraded thrust bearing, 14mm collar and 14mm spacer which provides durability which is important for running over 21 PSI
Machining for thrust collar / spacer maybe necessary, watch video in images
The factory collar and spacer have approximately 10mm of surface area on the thrust bearing, the larger 14mm collar and spacer have more surface area on the thrust bearing which is important to prevent thrust bearing failure if you are increasing
Staggered rear piston ring included for better sealing
We had great results out of these kits in our upgraded turbo rebuilds, the thrust bearing components in this kit is critical for reliability of your turbo. Do not use steel or factory thrust bearings if you are tuning and increasing the boost on the car it will fail.
