Complete in-house rebuild service for all Precision Turbo series, Next Gen, Gen 2, Gen 1, Sport, and XPR Pro Mod. Journal and ball bearing configurations, complete in-house rebuilds with VSR high-speed balancing. Rebuilding PTE turbos since 2008, we turn jobs around faster than the factory.
The vast majority of PTE turbos that come through our shop failed due to installation errors or external engine conditions, not a defective turbo. Understanding how the sealing system actually works is the first step to diagnosing the real problem. Turbos do not use rubber seals. They use metal piston rings seated in precision-machined grooves on the shaft. These rings are gas control rings, not oil seals. Their primary job is to keep boost pressure and exhaust gas out of the bearing housing, not to hold back oil under pressure. Oil stays where it belongs through a combination of centrifugal force, oil deflectors, and the pressure differential between the housings. When that pressure balance is upset, oil leaks. These are the conditions that upset it.
PTE turbos come in both journal bearing and ball bearing configurations. Journal bearings ride the shaft on a pressurized oil film and require higher oil flow with an unrestricted feed line. Ball bearing units use a ceramic cartridge and require less oil volume, but they generate more heat than journal bearings. Because of that, oil in a ball bearing turbo is primarily a coolant, not a lubricant. Journal bearings depend on oil to create the hydrodynamic film the shaft rides on, so lubrication is the primary role there. Both are fully rebuildable. The comparison table shows the key practical differences.
We rebuild every Precision turbo the same way regardless of series or bearing type, full teardown, full inspection, all wear items replaced, and VSR balancing before it ships back. No shortcuts, no skipped steps.
We have been rebuilding PTE turbos since 2008 and turn them around faster than the factory. Everything including VSR balancing is done in-house at our Dade City shop. Nothing leaves our facility.
The numbers in each model name tell you the exact wheel sizing. The first two digits are the compressor inducer diameter in millimeters, the last two are the turbine exducer diameter. A 6266 is a 62mm compressor, 66mm turbine. A 7275 is a 72mm compressor, 75mm turbine. If you know your wheel sizes but not your model name, we can identify it.
