17.01.2022 Chriss Deshele Built FA20DIT WRX with AVO Turbo kit was back in this week for the next stage of modifications. We fitted up AVOs Custom Jpipe that bolts up straight to their Turbo outlet and saw an immediate 25KW gain in power as flow restrictions were reduced. A Nostrum HPFP (High Pressure Fuel Pump) was installed to enable Chris to run ethanol straight from the bowser instead of having to mix 98ron and e85 to keep the blend below E65. PLUS, it increases fuel flow capaci...ty by up to 40% over the standard HPFP! Chris is super stoked with the results thus far as we have surpassed the initial goals of the build... he looks forward to the next round of mods. Stay tuned for the next round of mods as we wind up the boost currently sitting at 20.5psi.

This beast runs a deshele performance long motor package, Garrett GTX35R Turbo with GIR by Invidia Twist kit, Custom mobile custom fabrication pipework, and all the necessary bolt ons... all controlled by a COBB Accessport on Speed Density and Flex Fuel.

But, Derived Torque numbers are also attached. We tuned it up to make 314KW/755nm of Torque on 98ron, then on ethanol, it made 433KW and a whopping 1157nm of TORQUE!!!
