Stage 3 Tuning Package for i30N and N Performance:   This package now contains our Stage 1 upgraded turbo charger that features an uprated twin feed oversize 360 degree thrust bearing, oversized thrust bearing, oversized thrust collar and a staggered oil seal  for increased durability, particularly useful on track and mapped cars.

For the Stage 3 package. Firstly we remove the original factory Generation 1 turbo,  installing a brand new Hyundai Generation 2 Stage 1 upgraded 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. 

If you car has other modified components installed, for example and uprated intercooler high pressure fuel fuel pump,  GPF delete (if applicable) power will increase to circa 385 Bhp. An induction kit and sports cat will see power rise to 395++ 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.
