KC Jetfire Stage 2 Turbo

Gen 2

Supports: Up to 190cc/30% injectors


Features & Details:


  • Powder Coating can take up to 3 weeks before it ships
  • 515 to 615 HP with supporting mods
  • Redesigned Jetfire 64mm single plane point milled billet compressor wheel with extended tip technology
  • Redesigned Jetfire 66mm 10 blade quick spool turbine wheel
  • Upgraded .70AR race compressor cover with drilled hole surge ring for maximum air flow
  • New high flowing vanes
  • Upgraded 360 thrust bearing
  • 100% drop in ready (no modifications required)
  • New VGT solenoid
  • Brand new! NO CORE Required


This KC Jetfire turbo works great on stock injectors, but to fully take advantage of all the extra air flow you can run up to 175/30 or 190/30 injector. This is a great turbo for those looking to push the limits of their truck. This turbo is made for those who are looking for more top end power but still want to have the ability to tow max weight. This turbo will tow max weight with ease as long as you watch your temps and keep your rpms up. This turbo has a very loud whistle.


**We recommend 50 state legal SCT tuning to go with your turbo**


**Our polished covers require a 1-2 week lead time**


NOTE: We build our stage 2 turbos from 2003 cores.  These come with the better turbine wheel, better vanes, and will bolt on ANY YEAR.  Some years you will only run 2 mounting bolts instead of 3.

EXHAUST BRAKES:  We get asked a lot about exhaust brakes and if they work with our turbos, these will retain the OEM feature if the vehicles calibration allows and is setup for it. We have found that some brands have clearance issues and might cause the brake to hinder performance, rub the turbine wheel, or cause other issues.  These brakes typically use some sort of flapper to close which causes extreme exhaust back pressure to aide in braking.  This can be hard on a turbo and motor and is not recommended. 

Here are a few video links to show the power potential and towing power of the turbo:

KC is the only way

KC is the only way to go. I don't let my customers waste their money on any reman junk. I've installed at least 2 dozen and never had a problem or come back for turbo trouble.

Awesome turbo and intake. Sounds amazing! Install was easy.


Night and day difference with the Jetfire stage 2. Love it.


Good deal
