**If you purchase any VF40 or VF52 and do not purchase the Oil Line Kit Part# LGT-TURBOKIT at the same time your VF40 / VF52 will have NO WARRANTY.**

• Common causes of turbo failure:
• Restricted Oil Feed Lines/Filters: Starves turbo for oil, prevents proper turbo bearing lubrication. Kinks in the feed line can restrict oil flow
• Internal Engine Bearing Failure: Metal/debris shavings contaminates oil and causes scoring of turbo bearings/internal turbo components
• Underperforming Oil Pump: The pump is overworked as it tries to pump oil through the clogged filters. Even when new turbo and filters are installed, limited oil pressure is still an issue
• Improper Oil Drain: Oil return line is kinked, clogged, or restricted and not allowing oil to return to the motor from the turbo
• Improper Use of Sealants/Gaskets: Blockage to oil passages can be caused from improper sealer used in feed/drain fittings, pieces of gasket material can break off and enter turbo
• Dirty Air Inlet: Reduce air supply to turbo can increase EGTs and excessive heat will destroy/crack turbo and potentially create a vacuum to draw oil through seals in compressor housing
• Excessive Fuel: Leads to higher EGTs and can cause warping/cracking and bearing failure
• Improper Engine Shut Down: Rapid shut down of a hot engine will not allow oil to properly drain from the turbo and heat to adequately dissipate from the exhaust housing.
• Engine/Turbo Intake Debris: Broken engine components (pistons, rings, valves), nuts, bolts, dirt, foreign material can damage compressor and turbine wheels, cause turbo failure this is called FOD (Foreign Object Damage)
• Clogged Engine Crankcase Vent/PCV Valve: Builds excessive engine crankcase pressure and does not allow oil to drain (blows out turbo seals)
• Engine Blow-by: Causes excessive crankcase pressure and will not allow turbo oil to drain
• Excessive Oil Pressure: Too much oil pressure causes oil seals to fail
• Improper Feed/Drain Hose Sizing: Oil cannot feed or drain adequately

It is very important that you check these things prior to installing a new turbo. The Subaru Outback XT, Legacy GT are known to have multiple repeat turbo failures unless these are checked prior to installing a replacement turbo. Failure to do so may lead to your replacement turbo failing and that failure will not be covered under warranty.

Street 420 ft/lbs SB5-HDSS $623.21	SS: Performance Street Disc The ACT 6-Puck Sprung Hub Race Disc is SFI certified, so it is legal for all forms of racing that require SFI compliance. An ACT G6 race disc has a very durable friction surface with good spline life. The G6 was designed for a highly modified car that is drive to, on and from the track, as long as harsher engagement is acceptable. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub, though the G6 can still be noisier than a full face disc and will have some chatter.
Street 537 ft/lbs SB5-HDG6 $617.45	G6: 6-Puck Sprung Race Disc The ACT 6-Puck Sprung Hub Race Disc is SFI certified, so it is legal for all forms of racing that require SFI compliance. An ACT G6 race disc has a very durable friction surface with good spline life. The G6 was designed for a highly modified car that is drive to, on and from the track, as long as harsher engagement is acceptable. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub, though the G6 can still be noisier than a full face disc and will have some chatter.
Street/Strip 537 ft/lbs SB5-HDG4 $599.16	G4: 4-Puck Sprung Race Disc An ACT 4-Puck Sprung Hub Race Disc has very harsh engagement and is designed for road race cars only. A G4 friction surface has good durability and spline life characteristics under normal use. The sprung hub helps to reduce driveline shock and be relatively quiet compared to an unsprung hub but will definitely have chatter. The ACT G4 is SFI certified, so it is legal for all forms of racing that require SFI compliance. JSC does not recommend the G4 for a daily driven/street car.
Street/Strip 537 ft/lbs SB5-HDR6 $586.78	R6: 6-Puck Solid Race Disc The reduced inertia of the ACT 6-Puck Solid hub allows for very fast shifts at the expense driveability. An ACT R6 race disc friction surface has very good durability but will have shortened spline life. ACT designed the R6 for a highly modified track cars where harsher engagement is expected and some clutch chatter is not a problem. The 6-puck layout of the R6 will absorb, and dissipate, more heat than a 4-puck unit. The ACT 6-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. JSC does not recommend the R6 for any road going car.
Street/Strip 537 ft/lbs SB5-HDR4 $578.75	The ACT 4-Puck Solid Hub Race Disc is legal for all forms of racing that require SFI compliance. The biggest benefit of the ACT 4-Puck Solid Hub Race Disc is its extremely fast shifts thanks, in part, to its reduced inertia. An ACT R4 race disc friction surface has good durability but will have shortened spline life. ACT designed the R4 for a heavily modified drag race or road race cars where extremely harsh engagement and clutch chatter is expected. JSC does not recommend the R4 for any road going car.
