N14B16A / N18B16A
The N14 and N18B16A were co developed with PSA group and are essentially the same engine you’d find in the 207GTI, RCZ, DS3 etc. Branded as the EP6 or Prince engine by PSA. There are lots of variants of this engine. Even NA version but for our tuning packages we’ve focussed on the turbo charged variants fitted to the Mini. The N14 and N18 are different engines with the N18 featuring Valvetronic however from a tuning standpoint they respond in a very similar manner. While this engine gets a rough press for being a bit unreliable in our experience with proper tuning and maintenance these engines can actually be reliable and powerful even in a Motorsport environment.

210-215BHP - 300NM
The HT210 package is designed specifically to work with an original engine with no modification to the exhaust system, intake or intercooler. A modest increase in boost pressure combined with the use of high octane fuel gives a nice bump in performance without sacrificing reliability.
Requirements:
99 Octane Fuel
Parts Recommended:
Driven DI40 Engine Oil
NGK Iridium Spark Plugs
240BHP - 320NM
The HT240 package gets us up to the limit of what the stock Cooper S K03 unit can do without pushing it so hard we risk failures. Bringing the boost pressure up to between 1.3 and 1.4 bar increases the charge temperature dramatically so better charge cooling is required. Along with an exhaust system which reduces pressure build up on the turbine wheel.
Requirements:
99 Octane Fuel
Intercooler
Full Exhaust System Inc Sports Cat Downpipe
Parts Recommended:
Driven DI40 Engine Oil
NGK Iridium Spark Plugs
260-270BHP - 350NM
With the addition of the turbo and exhaust manifold from the JCW the increase in exhaust flow enables a healthy N14 or N18 to make quite a lot more power. This tuning package really brings these engines alive and combined with a well dialled in chassis can really produce some very surprising lap times.
Requirements:
99 Octane Fuel
Intercooler
Full Exhaust System Inc Sports Cat Downpipe
JCW Intake Pipe or AEM Intake
Genuine JCW Borg Warner Turbo
JCW Exhaust Manifold
Parts Recommended:
Driven DI40 Engine Oil

300-330BHP - 400NM
Our HT330 tuning package for the N14 and N18 engines is the ultimate and the limit of what is currently possible on a stock frame turbo. There are 2 options for turbos in this tuning package which do give slightly different results.
Option 1: TTE300
This option generally yields around 300bhp on a healthy engine and good supporting modifications. This is by far the cheaper option.
Option 2: 308 GTI/RCZ R Borg Warner Turbo and Manifold
This option is a great option for anybody serious about performance from these engines. The manifold and turbo are lifted from the 270BHP variant of the EP6 engine and are a far improved design when compared to the turbo setup on the other N14/N18 or EP6 engines. Fitment is tight and there are modifications needed to the car which mean this kit is only really suitable for track or race cars. 330BHP and 400NM is achievable reliably and this has been tested in endurance race events.
Requirements:
Hybrid Tune Forged N14/N18 Engine
99 Octane Fuel
Intercooler
Full Exhaust System Inc 308GTI Downpipe
Genuine 308GTI/RCZ R Borg Warner Turbo
308GTI/RCZ R Exhaust Manifold
