Stage 3 Tuning Package for i30N and N Performance:

The next stage over stage 2 historically covers any modification parts up to a hybrid turbo, in the order of priority these would be flex pipe,  Intercooler, GPF delete (if yours is a GPF car) and finally an exhaust. However, if you had all of these parts the car would be being held back by the standard turbo so not realising the best from these components and achieving 320 to 330 Bhp at a minimum cost of circa £2500 for these parts, plus £595 for mapping, giving a total cost of circa £3095. We feel this is quite expensive route to get an extra 50 Bhp...

However, with the advent of the Generation 2 car we feel a better cost to Bhp ratio is to supply & install the Generation 2 turbo, a 76mm Flex pipe along with a remap which will achieve gains to 356bhp for £3396 an gain of 86 Bhp which offers a much better £ to Bhp ratio. 

For the Stage 3 package. Firstly we remove the original factory Generation 1 turbo,  installing a brand new Hyundai Generation 2 turbocharger complete with new gaskets and seals. The original flex pipe, that joins onto the end of the cat pipe section, is quite a restrictive as its internal diameter is at worst only 60mm and at best 64mm.  This flex pipe is changed for a high flow 76mm version getting rid of this restriction in gas flow, once fitted the the oil and filter is change, then its round into the dyno cell for a full engine diagnostic test first. A Rolling Road calibration, set up and testing session follows with full data-logging and map optimisation. Exclusive Courtenay Sport software is written and installed raising the boost levels, whilst optimising the fuel and timing curves.  With Stage 3 we normally see peak power gains of 80 -90 bhp so typically 350 to 360 Bhp. 

The Generation 2 Turbo Explained

With the Generation 2 Turbo Hyundai have done much more than simply tweak the compressor and exhaust wheels, it is a complete re think.  The manifold and exhaust housings are much larger and the turbo rotation direction has been reversed for improved flow through the exhaust manifold and exhaust housing. The compressor and exhaust wheels are larger in size and the inlet on the compressor housing has increased in size from 53 to 56 mm which means that the bolt on 90degree alloy inlet casting now matches it in size, removing the previous 1.5mm step thus smoothing the air transition up to the compressor wheel.  

Turbo Specification Changes in Brief

Turbine Compressor Wheel (cold side) +4mm

Exhaust Wheel (hot side) +6mm

Turbo inlet up from 53 to 56mm to match the 90 degree bend inlet casting.

Width on manifold collector +14 mm


For best results we recommend using 99 Octane fuel such as Shell V Power, Esso Synergy Supreme + or Tesco Momentum, however, as we map to suit your car as it is presented on the day, we can also map for 97 Octane BP Ultimate at a slightly reduced power output.
