Solenoid Injector Upgrade for Oval Port MK6 / Mk7 2.0 TDI Common Rail CR Engines

All injectors supplied are all brand new Bosch units and Digitally Calibrated to the most extreme accuracy
These can safely take up to 300bar over the Stock 2000bar pressure

Estimated Power Capabilities:

Stock (03L) Injectors - ~280bhp / Stock (04L) Injectors - ~200bhp
Stage 1 - 320bhp
Stage 2 - 450bhp+
Stage 3 - 500bhp+

These figures are the limit of the injectors. To reach these limits you will also require other supporting mods (see below)

All parts have be developed and tested on our Arosa drag car - https://www.darksidedevelopments.co.uk/arosa-mk2-2-0-16v-common-rail/

Steps to be taken when upgrading 2.0 TDI Common Rail Engines

Larger Turbo - You will need a turbo capable of the power you are trying to achieve

CP3 Fuel Pump - The stock CP4 Pumps will experience Rail Drain at around 250bhp

CP3 Fuel Pump + Cams (Stock Injectors) - To max out the stock injectors (~280bhp) you will require the CP3 Pump + Cams or Ported Head
For 280bhp+ Upgraded Injectors are Required

CP3 Fuel Pump + Ported Head + Cams + Upgraded Injectors - All these are required to achieve over 300bhp

Upgraded Cams can be found here - https://www.darksidedevelopments.co.uk/products/performance-race-camshaft-kit-for-1-6-2-0-tdi-common-rail-engines.html
CP3 Pump can be found here - https://www.darksidedevelopments.co.uk/products/cp3-fuel-pump-conversion-kit-for-2-0-common-rail-engines.html

Please Note:

Stock CP4 Fuel Pump will not work with Stage 2 & 3 Injectors, this would cause Limp Mode due to low rail pressure so a CP3 Pump would be required

Stage 2 & 3 Injectors will also not be effective without head work or cams, but can be installed to shorten the injection duration

The ECU Software will have to be re-calibrated when fitting these injectors for a smooth idle and safe Exhaust Gas Temperatures (EGT)
