Kassel Performance View established S54 packages

Coyne Performance Engine Program

Build your S54 around the way you actually use it.

Configure the foundation of your custom E46 M3 engine. We will review the complete combination, confirm compatibility and prepare an individual quote before accepting the build.

Choose a starting path

Begin with a proven CPe package, start from scratch, or let us recommend the foundation.

Proven CPe PackagePreload one of the established Stage 1–4 foundations, then show us any requested changes.

Fully Custom BuildChoose the engine architecture and supporting systems without starting from a packaged configuration.

Recommend a PackageDescribe the car and goals. CPe will identify the nearest proven package and required changes.

Established package starting point

Application

Tell us what the engine needs to do.

Street / PerformanceResponsive, durable and suitable for regular road use.

Track / RaceSustained high-load use and a more focused build.

Mixed UseStreet manners with regular HPDE or track operation.

Naturally AspiratedStock-displacement, high-compression or stroker combinations.

Forced InductionTurbo or supercharged applications requiring the appropriate compression, sealing and rotating assembly.

Target output or goal Primary fuel

Core and engine architecture

Choose the basic block, bore, stroke and core path.

Stock-Displacement Rebuild87.0 × 91 mm nominal S54 architecture, subject to inspection and machining requirements.

87.5 mm / Stock StrokeThe established foundation for many naturally aspirated and moderate forced-induction builds.

87.25 mm / Stock StrokeAn additional non-sleeved bore option selected when it best fits the block and build plan.

3.4L Stroker87.5 × 95 mm, approximately 3.43L, with a matched stroker assembly.NA focus

VAC/Arrow Premium Stroker97 mm Arrow-manufactured billet crank with a matched VAC piston and Arrow rod package. Final bore and compression are selected for the application.3.30–3.50L range

Sleeved FI FoundationCPe-supplied sleeved block. Final bore and rotating assembly are confirmed for the specific build.No core required

Requested bore Requested stroke

Send My Core FirstSubject to inspection of the block, crankshaft and cylinder head.

CPe Exchange EngineAdds the applicable core charge and return requirements.

CPe-Supplied Sleeved BlockAutomatically selected with the extreme sleeved foundation.

Rotating assembly

Select the intended compression and connecting-rod package.

Compression ratio / piston direction Connecting rods

Cylinder head and camshafts

Choose the level of head preparation and valvetrain.

Stage 1 HeadThe straightforward performance rebuild foundation.

Ferrea ValvetrainComplete valvetrain package for a more demanding application.

CNC-Ported / FerreaFor combinations where the cylinder-head work supports the rest of the build.

Camshaft package

Included work and optional systems

Core CPe processes remain standard on every build.

Always included

Standard CPe VANOS reliability service
Individual measurement and clearancing
Serialized engine build/blueprint record
New OE BMW oil pump unless a dry-sump option is selected
Final technical review of the complete combination

Complete VANOS Valve BodyOptional replacement beyond the standard reliability service.

Dry-Sump OptionRequires application and system review.

Engine DressingRequest accessory transfer or a more complete assembly.

Installation at KasselQuote removal, installation and supporting work separately.

Engine management and existing hardware

Tell us what will control and support the completed engine.

Engine management Forced-induction system, if applicable Fuel-system details Exhaust/header configuration

Parts the customer already owns

CrankshaftMust be identified, measured and accepted before use.

Pistons / RodsCompatibility and condition must be confirmed by CPe.

CamshaftsProfile, condition and application must be confirmed.

Cylinder HeadRequires inspection before machining or component decisions.

Dry-Sump EquipmentSystem completeness and vehicle integration require review.

Forced-Induction HardwareInclude exact system details in the project notes.

Vehicle and contact details

Give us enough context to price and review the request.

Name * Email * Phone Vehicle / chassis * Completion path Desired timing

Current hardware, vehicle history and anything else we should know

Have build sheets, oil-analysis reports or component photos?Do not place sensitive files in this form. After reviewing the request, CPe can provide the appropriate way to send supporting documentation.

Measured, assembled and documented in-house

A build record for the engine you actually receive.

Performance engine builds include a serialized CPe build/blueprint record. Applicable machining and assembly measurements are recorded throughout the process; the final record reflects the individual engine rather than a generic specification sheet.

Cylinder-bore and piston measurements
Piston-to-wall, main-bearing and rod-bearing clearances where applicable
Piston-ring end gaps and relevant rotating-assembly measurements
Component weight or balance information where applicable
Applicable machining information and final assembly notes
