Engine Building & Custom Builds
From a factory-spec rebuild to an 800 HP turn-key stroker — machined, assembled and dyno-proven in our own Kessel workshop, with paperwork for every step.
What We Build
Tell us the platform, the power target and what the engine lives in. We spec it, build it, prove it on the dyno.
Street & Restomod Builds
Reliable, torquey crate-level builds for classics and restomods — factory drivability with modern internals. LS, Small/Big Block Chevy, Ford Windsor, Mopar.
Race & Strip Engines
Competition engines built to your class rules: forged internals, solid or roller cams, dry-sump options, full balancing and blueprinting.
Diesel & Heavy-Duty
Tow and work-spec diesel rebuilds — Cummins, Power Stroke, Duramax — built for torque and longevity, not dyno bragging rights.
Marine Engines
Marine-spec builds with correct cam profiles, brass/stainless freeze plugs and corrosion-resistant hardware. Run-in tested in our 3,000 L tank.
Swap Packages
Complete LS/LT/Coyote swap kits: engine, mounts, headers, wiring and ECU — engineered to fit your chassis before a bolt is turned.
Turn-Key Combos
Engine + transmission packages, matched and tested together. Bolt in, wire up, drive. Ideal for project cars and dealers.
Every Build Includes
No "mystery motors". Whether it's a stock-spec rebuild or a full custom stroker, the same discipline goes into every engine that leaves Haagweg 40:
- Full machining in-house — boring, honing, decking, balancing, head work
- Blueprinted assembly — every clearance measured and recorded, not assumed
- Written build sheet — parts list, clearances, torque specs, cam card
- Dyno verification — break-in and power runs in our 1,500 HP dyno cell
- Dyno data sheet — your engine's actual torque and power curves
- 12-month warranty — parts and workmanship, registered to you
From Idea to Dyno Sheet
Typical lead time 4–8 weeks depending on parts. You'll know exactly where your build is at every stage.

What Does a Build Cost?
Every build is quoted in writing before work starts. These starting points help you budget:
| Build Type | Includes | Starting From |
|---|---|---|
| Stock-spec rebuild | Refresh to factory specification, stock internals, dyno check | €3,500 |
| Street performance build | Upgraded cam, valvetrain and gaskets, ~400–500 HP targets | €6,500 |
| Custom stroker / race build | Forged rotating assembly, heads, full blueprint, dyno tune | €12,000 |
| Marine build | Marine-spec components, corrosion protection, tank-tested | €7,500 |
| Swap package (LS/Coyote) | Engine + mounts + wiring + ECU, chassis-specific | Quoted per project |
All prices include VAT. Core charge applies where no exchange engine is supplied — see Core Returns.
Common Questions
Yes — that's how we prefer to work. Tell us "550 HP street LS on pump fuel" or "1,000 HP strip car on E85" and we spec internals, heads, cam, induction and tune to hit it. The dyno sheet proves the result before you pay the balance.
Either way works. Supply your own engine and we build on it, or we source a core for you — the core charge then applies. Your old engine can also be returned for the core deposit afterwards. Details on our Core Returns page.
You get photo updates at every stage gate: teardown findings, machining complete, assembly complete, dyno session. Questions mid-build? Email or call — you talk to the person actually building your engine.
Yes — purpose-built wooden crate, shock indicators, moisture protection, fully insured and tracked across the EU. Track it on our tracking page the moment it leaves Kessel.
We install everything we build — mounts, wiring, ECU, fluids, dyno break-in — at our Kessel workshop. Vehicles collected and delivered across NL, BE and western DE. Ask for installation when you request your quote.
