Joaquin's 2017 STI - EQT SL450 91 and E85!

Posted by Ed Susman on

This 2017 STI came to us with only 4500 miles and a couple basic mods. The customer wanted a nice upgrade on pump gas and E85 that would scale up when he builds the motor in about a year. So we designed a nice setup featuring our EQT SL450 turbo. We installed all the parts and tuned the car on 91 and E85.

The final setup consists of:

EQT SL450 Turbo
TurboSmart Kompakt BPV
Perrin 3" Inlet
IAG TGV Deletes
Tomei ELH/UP
Invidia Catted DP
Invidia Q300 CB
ID1300cc Injectors
Cobb FPR Kit
DW300 Fuel Pump Kit
Prototype Flex Fuel Sensor Kit
RPS Street Max Clutch
Cobb AccessPort V3

Finally, we tuned the car on 91 Octane and E85, On 91 Octane, the car is running 20psi on 91 Octane and 22psi on E85. The results are amazing response with over 420whp. The turbo has much more to give once the engine is built next year!

Here's a shot of the engine bay:
