Factory Tour


Our Engines Feature:
New pistons, rings, timing components, freeze plugs, gasket sets, valve guides, lifters, oil pumps, rod bearings, main bearings and cam bearings
Crankshafts are reground, polished, and oil holes chamfered to rigid specifications
Connecting rods are checked for bend or twist, resized and honed to O.E.M. specifications
Valve seats are 3-angle cut for optimum sealing
All new valves**
Blocks are shot blast cleaned and magnafluxed to assure unseen cracks do not cause premature failure
Block deck and cylinder heads are resurfaced to assure proper sealing -- All blocks are Line honed
Engines are 100% functionally tested
New cams are used on flat tappet OHV applications*
Fel-Pro is our primary gasket supplier
*Virtually all applications
**On applications where new valves are not used, valve stems are centerless ground, butt cut, and chamfered to assure proper clearance and oil control

Engine Guy distributes the highest quality remanufactured engines in the world.  Our remanufacturing facilities cater to and have fulfilled the needs of Original Equipment Manufacturers such as Ford, GM, and Chrysler Corporation.

Our engines are tested and re-tested. We check cylinder bore cylindricity and machined surfaces using the revolutionary Hommel surface measuring gauges. With this level of attention to detail, it’s no wonder our manufacturing facility has achieved ISO 9002/QS9000 compliance and ISO 14001 Environmental Certification. But our quality manufacturing process is not limited to technology alone. We also have a vigorous process improvement program that continually enhances our ability to produce a better product quicker, thus driving down costs for our customers. And although our people and processes are some of the best available anywhere in the world today, we back them up with a quality assurance department that is tasked to ensure that the high standards we set for ourselves — often higher than those required by our customers — are always met.


Our Transmissions Feature:
At core teardown, ALL friction material and rubber components are discarded. Pistons ARE NOT air-checked with old seals and reused. "Good enough" isn't.
External case surfaces are painted and gasket surfaces are refinished.
Hard parts are checked against exacting standards and remanufactured using processes available, but largely unused, by most rebuilders.
Problematic hard parts such as 4L60/E reaction shells are replaced with new OE components or aftermarket upgrades.
Units are assembled with OEM hard parts and soft parts except in cases where aftermarket has proven superior.
Valve bodies are remanufactured using the best of factory and Sonnax components and go through a thorough preliminary check on an AXI-LINE valve body tester.
All electronics are functionally tested. TCC, PWM, PSM, and EPC are replaced 100%. Transmissions with solenoid bodies get new OE replacements. The MLPS is included AND functionally tested.
Each part and process is checked by multiple technicians before final assembly.
Our transmissions use Art Carr torque converters*
Transmissions are again tested electronically and hydraulically at very low RPM on the dyno before their actual full-power run.
The Mustang dyno tests the transmission using power and loads that simulate its intended use.
*certain applications use OE


Horizontal CNC Machining Centers

1.Consistent, reliable block machining and cylinder boring

2.Flexibility to machine multiple engines and engine families

3.Precision liner glass scales in X, Y and Z axes

4.Turn boring accuracy to +0.05 mm

5.Consistently achieve highest accuracy measurements

6.Reduce cycle times by 55%



This computer-controlled process buffs and cleans the intake and exhaust manifold surfaces on cylinder heads. The use of robotics provides:

1.Tighter tolerances

2.Dependable repeatability

3.Higher cyclic rates


Guy Current (DC) Torque

Torque-to-yield fasteners require DC-drive, controlled fastening systems to correctly and consistently tighten bolts to precise specifications and tolerance ranges.  The electrically controlled torque guns and fastening tools are used in three critical areas:

1.Cylinder head bolts

2.Main bolts

3.Connecting rod bolts


CNC Crankshaft Grinder

Engine Guy offers its premium engines with cutting-edge technology for the fully automatic production process. Typically found only in OEM plants, the capabilities of the new generation CNC Crankshaft Grinder easily exceed current requirements.  The CNC Crankshaft Grinder is designed for complete grinding of crankshafts in one chucking. This technology offers:

1.Tighter tolerances

2.Stabilized dimensional accuracy and surface quality

3.Ability to achieve and consistently maintain highest product quality


Crankshaft Micro - Polisher

Low-velocity abrading process uses lower cutting speeds (compared to grinding) and lower pressure to minimize heat, resulting in excellent surface, size, and geometry control. This technology is used in most polishing applications where high loads and tight tolerances are required in today’s applications.


CNC Rod Honing

The Sunnen KGM-1000® KROSSGRINDING System® is the choice for extreme accuracy when honing connecting rods. The KGM system is capable of holding the tightest tolerances in the industry. It can deliver accuracies as good as 0.00001 in. (0,00025 mm) in straightness and .00015 in. (0,0
