Our OEM+ Stage 3 upgrade offers a complete, turn-key package that is entirely usable on a daily-driven car yet offers devastating performance just one squeeze of the throttle away.  


An exceptional value package of the highest quality, intelligently-designed hardware, matched in to our superb OEM+ Performance Software. Reliability comes as standard - fit it, then just enjoy it!


Power gains are sensational. This package is more than capable of delivering over 500bhp - although we have calibrated it to a safer level of 480bhp, confidently leaving plenty in reserve.


Drivability and reliability are right up there alongside outright performance. By using the stock IHI housing, a low-lag spool on the turbo and great efficiency ensure power, smoothness ...and even surprising economy.



The OEM+ Stage 3 kit comes with our beautiful OEM+ software - all developed specifically to match the hardware and tested over 2 years. Right first time, every time.


Our Stage 3 kit is not just about bolting a big turbo on. It comes with our matched hardware parts, all developed to flow alongside one another.


One of the main reassurances of our OEM+ Stage 3 is that all the turbocharger's factory mountings oil lines, even gaskets are retained. No aftermarket fixings, no adaptors, no worries.


As well as the Stage 3 kit itself, our full range of other supporting hardware has been developed alongside.  From R600 intake, Intercooler, Oil Management, Downpipe, it’s all perfectly matched together.


Let’s be honest, nobody chooses the Stage 3 upgrade for any reason other than performance.


Instant, supercar-like power is the reason we do this! But the RacingLine Performance OEM+ Stage 3 kit offers you much more besides, in terms of driveability, simple installation and reliability.

Why do we calibrate power output to 480bhp when this kit could easily deliver more? It's very simple: that's the level that our research shows is safe for these engines and transmission.

There are of course turbo upgrades out there that promise more power. But just a quick check on the internet will prove our point - that over 500bhp will cause failure unless major engine rework is done first. Simple as that.

As well as your OEM+ Stage 3 kit (as above), there are a few other 'must haves' that are important to achieving the power levels.  These are not included in the kit  - as we know that many Stage 2 customers will already have one or all of these fitted that can be retained.  We don't want you spending your money twice!

Naturally, we recommend our own RacingLine hardware parts listed above to make the power numbers. These are the components that our OEM+ Performance Software calibrations were developed around.  But other-brand products, providing they are high quality alternatives, should support the OEM+ Stage 3 kit just fine.

Please note that it is essential at Stage 3 power & torque levels to upgrade your clutch (on manual 6-speed cars) or for DSG cars, to install our OEM+ TCU Dynamic Software.


All of the above power figures are accurate, tested illustrations; however, please do remember that actual power figures can vary up or down slightly dependant on many factors such as the condition of your engine & ancillaries, the fuel quality, DSG TCU map, other modifications fitted, and even testing methods.

Also please remember that changing your car's software will affect its manufacturer warranty. It is your responsibility to notify your insurer and to ensure that your car still complies with all your local road laws. Please consult your supplying dealer for full information.
