Engine Swaps
LS, LT, Coyote, modern HEMI, and custom powertrain installations designed around the vehicle. Mounting, oil pan clearance, accessory drive, wiring, cooling, fuel delivery, exhaust, and transmission compatibility are planned together.
Ekins Garage Performance
Modern power. Built to be driven.
Engine swaps, fuel systems, cooling, exhaust, drivetrain upgrades, tuning, and modern drivability for classic trucks and muscle cars.
Modern Performance
More power is only valuable when the entire vehicle is ready to use it.
A great performance build does more than make horsepower. It starts reliably, stays cool in traffic, shifts correctly, responds cleanly, and feels confident at highway speed. At Ekins Garage, every upgrade is planned as part of a complete system so the finished vehicle performs as well as it looks.
Performance Services
Power that is engineered, not just installed.
Performance parts should never be chosen in isolation. Engine output, fuel delivery, cooling, transmission, gearing, exhaust, electrical capacity, and tuning all affect how the vehicle behaves. We build complete packages around the vehicle, the driver, and the way it will actually be used.
Fuel Systems & EFI
Holley Terminator X, Holley Sniper EFI, FiTech, high-pressure pumps, return-style fuel systems, custom tanks, regulators, filters, and properly routed fuel lines for reliable modern fuel delivery.
Cooling Systems
Aluminum radiators, electric fans, fan controls, water pumps, overflow systems, transmission coolers, oil coolers, and airflow improvements designed to keep the vehicle stable in traffic and under load.
Custom Exhaust
Headers, stainless exhaust, X-pipes, H-pipes, mufflers, hangers, heat management, and complete fabrication built for sound, clearance, serviceability, and long-term durability.
Drivetrain Upgrades
Overdrive transmissions, 4L60E, 4L80E, 6L80, T56 manual conversions, rear axle upgrades, limited-slip differentials, gearing changes, transmission cooling, and custom driveshafts.
Performance Tuning
ECU calibration, Holley tuning, cold-start correction, idle refinement, air-fuel adjustments, throttle response, shift behavior, and drivability tuning that makes the vehicle enjoyable in real-world conditions.
Built as a Complete Machine
Every upgrade should make the whole vehicle better.
A larger engine changes more than acceleration. It affects cooling demand, fuel pressure, electrical load, transmission capacity, driveline strength, exhaust routing, braking confidence, and overall balance.
That is why we do not treat an LS swap, EFI conversion, or transmission upgrade as a single isolated job. Every major component is evaluated against the rest of the vehicle so the finished build feels cohesive rather than pieced together.
The goal is simple: a classic vehicle that starts easily, idles smoothly, stays cool, cruises comfortably, responds cleanly, and can be driven with confidence.
Our Process
Built with purpose. Tuned for the road.
A successful performance build begins with the intended use of the vehicle. Street cruising, long-distance driving, towing, autocross, show use, and daily driving each create different requirements.
01
Consultation
We discuss your vehicle, current condition, performance goals, driving habits, desired power level, preferred transmission, budget, and long-term plans.
02
System Planning
The engine, fuel system, cooling system, exhaust, transmission, gearing, electrical capacity, brakes, and driveline are evaluated as one complete package.
03
Installation
Components are installed with careful attention to fit, routing, heat management, service access, ground clearance, appearance, and future maintenance.
04
Wiring & Integration
Engine controls, sensors, gauges, fan controls, charging systems, transmission controls, and supporting electronics are integrated cleanly and logically.
05
Calibration
Fuel delivery, idle quality, cold starts, throttle response, fan operation, transmission behavior, and drivability are adjusted for the complete vehicle.
06
Testing & Refinement
The vehicle is inspected, heat-cycled, road tested, adjusted, and reviewed under real driving conditions before final delivery.
The Ekins Garage Standard
Modern reliability. Classic character.
The best performance upgrades make a classic vehicle easier to enjoy, not harder to live with.
Build for Real Use
Street manners, cooling, reliability, serviceability, comfort, and highway behavior matter just as much as peak horsepower.
Engineer the Complete System
Every major component is selected to support the rest of the vehicle rather than create another problem somewhere else.
Finish the Details
Wiring, plumbing, brackets, fasteners, hose routing, clearances, heat shielding, and final calibration determine whether the build truly feels complete.
Performance Upgrade FAQ
Questions before starting your build.
Every vehicle is different, but these are some of the most common questions owners ask when considering an engine swap or performance upgrade.
What vehicles can Ekins Garage perform engine swaps on?
We work on classic trucks, muscle cars, hot rods, and custom vehicles. The final scope depends on the condition of the vehicle, available space, intended use, parts availability, and the supporting systems required for a safe and reliable installation.
Can you install an LS engine in a classic truck?
Yes. An LS swap can provide modern power, parts availability, electronic fuel injection, and improved drivability. A complete swap may also require fuel system changes, cooling upgrades, wiring, exhaust fabrication, transmission integration, and tuning.
Is EFI better than a carburetor?
EFI can improve cold starts, idle quality, throttle response, fuel control, and altitude compensation. The best choice depends on the vehicle, engine, desired appearance, driving style, and how much modernization the owner wants.
Will a performance engine require a new cooling system?
Often, yes. Increased power and modern engine swaps can create different cooling demands. Radiator capacity, fan airflow, water pump selection, fan controls, hose routing, and underhood airflow should all be considered.
Can you make a classic vehicle comfortable at highway speed?
Overdrive transmissions, proper rear gearing, balanced driveshafts, improved cooling, accurate tuning, modern fuel delivery, and thoughtful suspension and brake upgrades can dramatically improve highway drivability.
