EQT-SL450 Turbo Upgrade (Subaru WRX 02-14, STI 04+)

Introducing the EQT-SL450 Turbo!

This is currently the largest turbo variant we offer and it really shines on E85 or race gas. The SL450 is a step above the SL400 with a larger TD06SL2 based turbine and a custom billet compressor wheel along with a 3in inlet and 8cm exhaust housing. The SL450 can do 350whp on 91 Octane and over 450whp on E85 while still retaining excellent spool and mid range response. Its a great option for those running higher octane fuels that can take advantage of the higher boost and flow levels this turbo can offer.

Here is a dyno chart showing a stock 2011 STI baseline along with a built 2011 STI utilizing the SL450 turbo on 91 Octane and E85. This car has a built shortblock and flow and fueling mods to support the additional power. As you can see, there is no added lag over a stock STI while making more than twice as much power! The response to power ratio this turbo offers simply can't be beat! 

** These are wheel power/torque numbers from our AWD chassis dyno


The price includes water lines, oil lines, and gaskets necessary for the install. 

*** The 3 inch inlet is recommended, but we can make these with a 2.4 inch inlet upon request as well.
