Engine Rebuilding

WRG Paint & Body in Charlotte offers full engine rebuilding services. Whether restoring a classic or repairing a tired powertrain, our team delivers performance, precision, and long-term reliability.

A well-built engine is the heart of every great vehicle. At WRG Paint & Body, we offer full engine rebuilding services for customers who want to restore lost performance, extend the life of a vehicle, or breathe new power into a classic car. Whether you’re dealing with oil burning, compression loss, or just age-related wear, we take your engine down to the bare block and rebuild it with care. From daily drivers to vintage restorations, our Charlotte-based shop delivers the craftsmanship and mechanical expertise to make your engine run better than ever—and for the long haul.

Comprehensive Inspection and Disassembly

Every engine rebuild starts with a full tear-down and inspection. We disassemble your engine piece by piece, clean each component, and carefully evaluate wear, tolerances, and damage. We check bearings, seals, piston rings, timing chains, lifters, camshafts, and cylinder head integrity. This process gives us a clear roadmap for your rebuild and helps avoid surprises later. Whether your engine was running rough or fully seized, we assess every part to decide what can be machined, what needs replacing, and what can be upgraded for performance or longevity.

Machining and Precision Reconditioning

We work with trusted machine shops and in-house equipment to prepare your engine’s hard parts for reassembly. This includes cylinder honing for proper ring seating, crankshaft polishing, deck resurfacing, and valve seat machining. If your block needs boring or your crank needs grinding, we’ll machine everything to exact specs and provide documentation on tolerances. These precise operations ensure your rebuilt engine starts strong, runs smooth, and lasts for miles. Every cut and pass is measured twice—because precision equals reliability.

OEM or Performance Rebuild Options

When it comes time to reassemble, you can choose between a factory-spec rebuild or a performance upgrade. We offer OEM-quality internals for long-lasting daily drivers, or forged components for performance builds. We can upgrade cams, increase compression, improve cooling, or even prep your engine for turbo or track use. Our team assembles everything in a clean environment using torque specs, assembly lubes, and sealing procedures that meet or exceed industry standards. It’s not just rebuilt—it’s built better than before.

Break-In, Testing, and Final Verification

Once your engine is assembled, we perform a full series of post-build checks including leak-down, compression, and timing verification. We also provide guidance for the break-in period, oil types, and service intervals to make sure your fresh build starts its life right. If your vehicle is staying at WRG for installation, we complete the swap and test everything under load. If it’s being delivered, we provide full documentation and recommendations for tuning or dyno time. Every rebuilt engine leaves our shop with confidence and clarity.

Ideal for Classic Cars, High-Mileage Vehicles, and Enthusiasts
