SneedSpeed 2007-2013 R56 Cylinder Head

The Sneed Super Cooper series of cylinder heads is our premier fully assembled MINI Cooper cylinder head. Each head is cleaned, checked and then built into a Super Cooper Street, Sport or Super head by our inhouse engine machinist.

Super Cooper Street - (Stock replacment) heads are fully rebuilt to better than OEM specs with OEM parts. They are milled and trued to .0001 of an inch on the engine sealing surface and then receive a high flow valve job and valve facing as well as setting the valve spring seat pressures for best performance. This is a great stock replacment head, built by the leading MINI race parts manufacturer, with a few race touches.

Super Cooper Sport, heads receive all the above plus a high performance cams and new high performance valve springs. If you're tracking your MINI on a budget, this is the head for you. Direct, bolt on replacment for the stock head with a 15-20 horse power increase over the stock unit with ECU tuning, REV limiter can be increased to 8000rpm. But no ECU tuning required to use the head.

Super Cooper Race, heads receive everything above, cleaned valve bowls, swirl porting and polishing, a high performance cam, 1.5mm oversized super alloy valves, and race valve springs with titanium retainers that are 45% lighter than OEM retainers. All this creates a head that makes big power, handles high boost levels and revs past 10,000 RPM without valve float. ECU tuning is required.
