Moving onto the fuel system we first look at power goals and fuel type to be used. Below is a list of the Injector Dynamics Fuel Injectors for the K20 and K24 engines. ID injectors are the only injectors we use as they simply work better than anything else on the market when it comes to long term reliability and consistent flow across all injectors. All ID injectors are engineered to be used with alcohol based fuels like ethanol, methanol, E85 and Flex Fuel. ***save $50 on any injector order with coupon code: hohu50***

All of these injectors will work with OEM fuel rail or any aftermarket replacement fuel rail but if you are looking for the best option on the market go with the radium fuel rail listed above matched with the Radium DMR its a super compact and effective combo. We highly recommend running your turbo K on E85 or Flex Fuel if you have the fuel available to you locally. These alcohol based fuels allow the engine to safely make more power compared to running on 93 octane.

The Best Turbo & Wastegate for K Series Engines

When it comes to choosing the right turbo and wastegate for the K20 or K24 it’s important to consider your power goals and error on the side of “big”. The Honda K series cylinder head flows extremely well and to get the most out of any turbo K the turbine (exhaust side of the turbo) and wastegate must be able to keep up with the flow. The last thing you want is a small turbo choking out your power from 6000-9000RPM or a small wastegate causing big boost creep problems. Below is a list of our most popular turbos and wastegates for the K series. All of these turbos/wastegates feature a full V-Band inlet/outlet configuration for easy install and leak free operation. 

  • Tial V60 Wastegate is a 60mm external wastegate perfect for any K series making 500+ HP. Using the tial 60mm WG ensures super accurate boost control and 0 boost creep potential even at high RPM
  • PTE 6870 Ceramic BB turbo packs a HUGE 1100HP punch in a small package. This Turbo works great on any turbo K series build looking to make over 600HP
  • PTE 6466 Ceramic Ball Bearing Turbo is a medium sized turbo that will make 450-500HP on low boost stock engine. Turn it up with a build bottom end and the 6466 will support 800HP no problem with great response. 
  • Tial MVR wastegate The tial MVR is a 44mm external wastegate that is a good budget option and still works well IF you are willing to deal with the boost creep that comes with running a smaller WG.
