JASPER® Offers Remanufactured Toyota 1GR-FE 4.0L V6 Engines

Jasper Engines & Transmissions is pleased to announce the availability of the Toyota 1GR-FE to our remanufactured gas engine line. 

This 4.0L, DOHC, Single VVT, V6 engine, is available for the following Toyota applications:

2003-2015

4Runner

Tacoma

FJ Cruiser

Tundra 

“JASPER replaces the OE cast aluminum pistons with forged aluminum pistons of our own design,” says Brad Boeglin, JASPER New Product Development Group Leader. 

“The JASPER-engineered pistons have a 38% larger oil return area. This is coupled with the use of a two-piece oil ring design, replacing the three ring design of the OE piston. These two changes improve oil control, and prevent the oil rings from sticking.” 

“In addition, the JASPER-engineered piston has a profiled top ring land to reduce scuffing under high-load, and an anodized crown for higher heat strength, and top ring stability,” said Boeglin. 

“Our specially-designed pistons utilize a wider graphite coated skirt to prevent dry startup piston scuffing,” added Boeglin. “We’ve also improved the skirt profile for greater piston stability.” 

Each JASPER Remanufactured Engine is subject to strict, high-quality processes:

  • Disassembly, meticulous inspection and cleaning of components.

  • Precise machining for reliable performance.

  • Head and block surfaces strictly monitored to assure proper sealing.

  • JASPER’s Research and Product Development ensures inherent problems in OEM design are corrected. Units undergo a 50-hour durability test and a thorough auditing process.

  • Live-Run Testing, including recorded inspections of temperatures, oil pressure, vacuum and compression, provides piece of mind and assures reliability. 

  • Blacklight inspections ensure there are no oil leaks.

  • An available Premium Service Plan offers customers even greater value. 

The JASPER remanufactured Toyota 1GR-FE is covered by a 3-Year/100,000-Mile, nationwide, transferrable, parts and labor warranty. Full warranty disclosure is available upon request.

JASPER Conducts Submersion Pressure Testing on Subaru Boxer Engines


JASPER Associate Wayne Hedinger gives this Subaru 2.5L Boxer engine a submersion
pressure test to inspect for leaks.


Oil leaks have been a concern with Subaru’s 2.5L SOHC “Boxer” four cylinder ever since the engine appeared on the market in 1999.

As part of JASPER’s remanufacturing process, every 2.5L Subaru is pressure tested in a tank of water and checked for leaks, before it is live-run tested.

The heads, oil pan and oil pump are installed. All engine ports are sealed off and valve covers are attached. The unit is pressurized with 5 psi and lowered into the tank, where it’s submerged for a minimum of 30 seconds. During that time, Associates check for leaks at the oil pump seal, the cam seals, cam plug, cam cap sealing and the rear seal.

Once the engine passes this inspection, it’s removed from the tank and air dried. All the plugs and fittings are then removed. The water pump and timing components are installed; valves are adjusted and the engine is live-run tested.

 
 
 

JASPER Offers Remanufactured Subaru 2.5L SOHC Boxer Engine

Jasper Engines & Transmissions, the nation’s leader in remanufactured products, announces the availability of its remanufactured Subaru 2.5L boxer engine. This SOHC four-cylinder engine is available on exchange for the following vehicles:

1999-2010 Impreza/Forester
2000-2009 Outback/Legacy
2002-2007 Baja

“This remanufactured JASPER engine offers several advantages,” said Brad Boeglin, JASPER New Product Development Group Leader.  “We use multi-layer stainless steel design head gaskets, with larger embossments and coated with a rubber-based synthetic material to stop oil leaks.  Cylinder heads are installed with NEW torque-to-yield bolts to provide even clamp load and reduce head gasket failure.”

“The pistons are a JASPER-exclusive design that improves cylinder-to-wall clearance and oil drain back capability,” Boeglin said. “The pistons include a graphite coating to help prevent dry startup and piston scuffing.”

“The cylinder block is torque plate honed, a process which eliminates cylinder distortion after the head is bolted and torqued to the block,” he added.
 
Additional updates include: 100% installation of a NEW timing belt tensioner, idler pulleys, water pump and belt, which prevents the chance of timing component failure.  The engine is also live-run tested with recorded inspections of temperatures, oil pressure, vacuum and compression; assuring reliability and providing piece of mind.  A black-light inspection occurs after testing to ensure there are no oil leaks.

The JASPER remanufactured Subaru 2.5L SOHC boxer engine is covered by JASPER’s 3-Year/100,000 mile nationwide transferable parts and labor warranty. Full warranty disclosure is available on our website, or upon request.
