This is another CT26 turbo rebuild we performed at PRE. This turbo suffered failure due to mechanic’s error, who left a shop rag in the turbo inlet pipe. Compressor wheel was destroyed and a complete overhaul was a proper solution. This turbocharger will be rebuilt and installed on a customers Toyota Cressida with a 7MGTE engine. This turbo received the typical attention to detail we are use to at PRE. New compressor wheel, new rebuild components, rotor assembly balancing. This turbo received a genuine replacement Garrett 60-1 compressor wheel in the process.

APPLICATION:

1986-1992 Toyota Supra Turbo Mk3… 7MGTE engine
1988-1992 Toyota Cressida… 7MGTE engine
1986-1989 Toyota Celica All-Trac (GT-Four)… 3SGTE engine*
1990-1993 Toyota Celica All-Trac (GT-Four)… 3SGTE engine*
1989-1999 Toyota MR2… 3SGTE engine*
*modifications required

Another common turbo we rebuild at PRE. This is a stock CT26 found on the MK3(1986-1992) Toyota Supra. This turbo showed its age when we received it. Worn compressor wheel with chips and bents, excessive wear of the bearing housing, and typical cracks in the turbine housing inlet and wastegate opening. We did a complete restoration on this turbocharger. new compressor wheel, micro-polished turbine rotor shaft, all new bearings, seals, o-rings, and of course, balancing of the rotating assembly. Bearing housing was worn out due to age and possible oil starvation. We honed out the housing to the next size journal bearing. With the exception of bearing housing honing this turbo qualified for our Basic Turbo Rebuild process.

Below you will find pictures of the finished unit as well as individual component pictures before and after the rebuild process.

This is another type of Garrett T25 turbo we rebuilt at PRE. This particular turbo was in decent shape when it came in. It only needed our basic rebuild service to make it 100% again. Please look in the Turbo Services section for exact description of rebuild process.

APPLICATION:

1998-2002 Saab 9-3…B204E, B204L, B204R, B205E, B205L, B205R engines
can be adapted for use on 1998-2002 Saab 9-5 as replacement for Garrett GT17 turbo

Pictures of the finished unit:

This is an IHI VF39 turbocharger removed from a 2005 Subaru Impreza STI. The turbo was in decent condition to begin with and only needed a complete rebuild kit for the overhaul. Customer complained of minor oil consumption and smoking from the exhaust pipe. Inspection revealed a worn out turbine shaft seal. Complete rebuild was chosen as a solution. If you are already this far in the process why only replace one seal? We replaced all components to make this turbo 100% new. We disassembled the turbo, cleaned all components, and inspected everything. Surprising this turbo did not have the typical wastegate crack in the turbine housing. WOW! After complete inspection bearing clearances were checked using Mitutoyo micrometer and bore gauge. All clearances were within factory specification. Turbocharger rotor shaft assembly was balanced using a Schenck balancing system. This turbo is a perfect example of Basic Turbo Rebuild Service we offer.

APPLICATION:

2004-2006 Subaru Impreza STI… EJ257 engine
2002-2006 Subaru Impreza WRX… EJ205 engine
1998-2002 Subaru Forester… EJ20 or EJ25 engine swap
2003-2008 Subaru Forester XT… EJ25 engine

Pictures of the finished product:

Another turbo rebuild at PRE. This time we received a Subaru turbo that suffered a catastrophic failure. This turbo broke the turbine shaft due to lack of lubrication. Compressor wheel, bearing housing, turbine rotor shaft, and all consumable parts(bearings, thrust collar, shaft seals, o-rings, clips, and hardware). Turbine housing was media blasted by hand and polished afterwards. Turbine housing is ported and blended in the turbine inlet, wastegate area, and turbine outlet. Compressor housing passed inspection and received proper cleaning. Rotating assembly was balanced on a Schenck turbo balancing machine. (Note to all Subaru owners; clean or remove the oil filter for the turbo oil feed line. This clogged filter caused complete turbo destruction in minutes!)

Turbo Specifications:

• -Compressor Wheel: 52.5mm inducer / 68 mm exducer ( 6×6 blades compressor wheel), Superback design
• -Turbine Wheel: 58.8mm exducer / 67.14 mm inducer ( TD06H / 11 Blades )
• -Turbine Housing: Mitsubishi Heavy Industries(MHI) 78-10820 070 (7cm) ported housing
• -Turbine housing ported and blended originally by Deadbolt Performance
• -Compressor Housing: TD06 housing, standard 2.25 inch inlet
• -Turbo was Schenck balanced to less than 0.5g/cm2
• -Oil lubrication only! Not water cooled like OEM.
• -Turbo max rated at 440whp

 

Pictures after the rebuild:

Here are PRE we rebuild a lot of Garrett T25 turbochargers. This turbo is commonly found on Nissan Silvia/180sx/240sx cars equipped with SR20DET engines. A variation of the T25 turbo can also be found on the 2nd generation 95-98 Mitsubishi Eclipse(Eagle Talon), and 98-2002 Saab 9-3.

This turbo was rebuilt with all new bearings, seals, and o-rings. All bearing and turbine shaft clearances are measured using micrometers and bore gauges. Bearings housing is cleaned prior to inspection. When excessive wear is determined, it is rehoned to accept an oversized turbine shaft bearing. Rotating assembly is polished to remove any imperfections and balanced. Turbine housing is media blasted by hand and polished. After the turbo passes all clearance specification checks it is reassembled.

 

Pictures of rebuilt turbo:

Pavel’s Racing Engines now offers repair and rebuild services for 2009+ Subaru Impreza WRX IHI VF52 turbochargers. This turbocharger was improperly used and heavily abused causing thrust bearing failure, in turn causing turbine seal failure and excessive oil consumption. This turbocharger was disassembled, cleaned, inspected, all clearances checked with micrometers and bore gauges, and rebuild with all new consumable components. Compressor wheel was replaced and rotating assembly balanced. IHI turbochargers are known to suffer from boost creep issues, thus we opted to polish the turbine housing inlet. Most importantly, we modified the wastegate port in effort to reduce boost creep condition.

This is the finished product of our work:

This is another sample of our work. We rebuilt this improperly used and heavily abused turbocharger. Compressor wheel was replaced due to extensive wear, bearing housing honed out to accept oversized journal bearings, all new consumable components(piston ring seals, o-rings, c-clips, and hardware), rotating assembly balancing, all followed by careful assembly. The turbocharger is sold and the new customer could not be happier!
