Lohen MINI N18 Crate Forged Engine Build - Config 4
About Lohen Crate Engines
Lohen has used experience and knowledge of the MINI N18 engine to produce a remanufactured performance Crate Engine that strengthens the areas we see as common failure points from our tuning experience. The Lohen N18 Crate Engine is suitable for the MINI Cooper S 2010 - 2014 or MINI JCW 2012 – 2015 and is supplied on an exchange basis.
The Lohen N18 Configuration 4 forged engine features a closed deck construction using Darton's Modular Intergrated Deck (MID) sleeves. The closed deck construction removes the standard cylinder wall and the water jacket replacing these with the MID liners. The Darton sleeves form a solid construction within the block that prevents any cylinder deformation which occurs when boost levels and consequently cylinder pressures are increased. The Darton sleeves allow coolant to flow with its construction aiding engine cooling. The waterways are altered compared to stock so to compensate for this a Supertech performance head gasket is used to allow good flow
The Configuration 4 forged uses forged pistons and connecting rods form a solid bottom end of the engine. The N18 short block is assembled using new piston rings, Mahle Motorsport bearings throughout as well as ARP bolt and stud kits.
The cylinder heads are checked for straightness, then pressure tested as well as having the cam tolerances checked. The cylinder head in the Configuration 4 N18 engine benefits from full Supertech forged valves, beehive springs, and titanium retainers. These tolerate heat better than the standard OEM valve and the profile is optimised for gas flow. The springs are firmer than stock so operate faster avoiding problems relating to valve float and operation in higher RPM and boost points.
These improvements make the Configuration 4 well suited to the hardest driving conditions and most powerful MINIs.
All re-usable engine components are thoroughly cleaned and inspected and all engines are re-assembled using brand new gaskets, seals, and chains.
Please note - Lohen Crate Engines are supplied as timed-up bare units with a sump, oil pump, and rocker cover. All other bolt-on ancillaries are not included. The engines are therefore shipped dry and require final assembly and fluids prior to installation and starting.
If required, Lohen can supply a fully built engine for an additional charge. We also offer professional in-house installation and running in service at our workshop.
N18 Engine Installation kit is a comprehensive collection of parts that is suggested when installing a Lohen Crate Engine. Click Here For full details about the Lohen N18 Crate Engine Installation Kit - in summary, this includes 1 x running in oil, 2 x engine oil changes. oil filters, gaskets, coolant, water pump, thermostat, oil pressure sensor, necessary bolts
Optional Extras
Crank Shaft Balancing
Balancing the crankshaft is important when building a performance engine. Weight out of balance from the centre point has a direct relationship to engine speed so, for those pushing the MINI engine harder, it is vital the crankshaft is balanced to improve the durability of the engine and, in particular, engine bearings, reducing engine vibration and improving performance.
Surcharge
Exchange unit
Lohen will apply a surcharge to every engine sold unless a donor unit is supplied and it is deemed to be in re-buildable condition.
