This Subaru WRX STI runs a quick 10.99 elapsed time at the drag strip and it doesn’t even have an STI engine. The owner of this WRX STI doesn’t need an STI 2.5-liter to run 10s at the Calder Park and Heathcote Raceway in Australia. He built the Subaru racer in just three months and it’s powered by an Outback boxer engine. It must be because old Outbacks are plentiful down under and it was available for him to use.
The crazy thing about the car is, it’s set up as a track car and not really meant for the drag strip. The owner, Barry, wanted to dial in the car and took it out for a few runs down the strip to see how it would do. As you can see from the video below, it did quite well for a track car.
This Subaru WRX STI is pumping out 400hp using a 2.5-liter Outback boxer engine. Barry built it using forged internals, a Garrett turbocharger, MicroTech EFI and E85 fuel. The 400hp modified engine sends power to all four wheels.
How did he get 400hp from the 2.5-liter EJ series engine?
Take a 2.5-liter Subaru Outback powerplant, add forged pistons, ARP head studs, Kelford 264 camshafts, Garrett GT35R turbo @ 19psi, MicroTech computer, E85 fuel system, Turbosmart Eboost2 and oil & power steering coolers. If you have an older Subaru Outback 2.5 and want to have some fun, pull out the engine, do some modifications and stuff it in a Subaru WRX Bugeye for some weekend fun on the track or strip. Or, put it back in the wagon and have the fastest Outback on the planet.
