Engine Swaps, Build & Customization
From a straightforward donor engine swap to a full custom build, our Karachi workshop handles the fitment, wiring, fuelling and cooling work an engine swap actually needs — not just dropping it in and hoping.
What’s Included
Every engine swap is planned around your chassis, your goals and your budget — from a reliable daily-driver swap to a built engine for serious power.
- Donor engine fitment and mounting — custom mounts and subframes where needed
- Wiring harness integration for the swapped engine and ECU
- Fuel system builds and upgrades to match the new engine
- Cooling system builds and upgrades for the swap
- Driveline and gearbox adaptation
- Full custom builds from the ground up, not just bolt-in swaps
Fitment & Mounting
Custom mounts, subframes and clearance work so the swap sits right — not held in with whatever’s lying around.
Wiring & ECU
Clean harness integration for the swapped engine and its ECU — see our Wiring page for the full wiring scope.
Tuned & Sorted
Once the swap is running, we tune it properly on our rolling road dyno before it goes back to you.
Every Build Is Quoted Individually
Engine swaps vary hugely by donor engine, chassis and how much custom work is involved — there’s no flat-rate price for this one. Submit your build list or get in touch with what you’re planning and we’ll confirm scope and pricing.
