About this episode
Why does this 800hp car look like it belongs to racing classic DTM cars, and what's up with the 6 cylinders? Aleck Kazakovski of GotItRex explains some of the tech talk story of how this GC8/Type R STi has grown into the monster it is today, with multiple time attack wins in Australia and a unique but well-proven setup. The turbocharged EG33 is capable of 9,500rpm and 750kw (1000hp) at 40 PSI, but the team dials things back in the interests of reliability and wallet health to a 'modest' 600kw (800hp) at 25 PSI and a 9,000rpm limit. Madness! There isn't much that hasn't been touched on the EG33 to make this happen, including being bored and stroked with extensive headwork to give a very usable powerband with full boost from 4,500 rpm. Lubrication is handled by a custom GIR dry sump setup using existing off-the-shelf components. Clever! An EMtron electronics package helps keep it all working as intended, and a Modena sequential transmission package puts the power to the ground without turning into Swiss cheese as you would expect the OEM Subaru parts to; however, OEM housings and much of the physical placements are retained or at least are very close to where they were which keeps some of the heritage rather than being a complete Frankensteins monster. No doubt, this also enables an easy time with spares and repairs. A PE Racing pedal box and AP Racing calipers and rotors help haul the car up for the corners, with Aleck and the team opting to avoid some of the oversized rear brake issues many Subaru owners fall into the trap of, and ABS is on the cards for the future to help leverage the system further.
