Toledo, Ohio's Accelerated Performance created a stir last month with the first turbocharged BRZ. When they popped up on the North American Subaru Impreza Owners Club forum last month, John Visconti had squeezed 54.5 extra horsepower out of the Subaru BRZ's stock 2-liter engine.
He's since upped the ante, raising the boost from 4 to 10 psi and jacking the power output to 278 whp. That's 117 hp over the stock 161 whp out put. Not too shabby.
On the forum, Visconti said the kit — Accelerated performance's BRZ-300 turbo setup — costs about $5,000. He also told forum commenters that A.P. is working on making bigger turbos work as well.
Using new EcuTek RaceRom software for the BRZ/FRS and an Omni 4 Bar MAP Sensor in conjunction with A.P.'s BRZ-300 turbo kit, Visconti clocked the custom BRZ's power output at 278 whp at 7,200 rpm. The car cranked 215 lb-ft of torque at 5,500 rpm; a 79 lb-ft boost over stock numbers.
Visconti told us peak horsepower was 286 on one run, but they "weren't looking for peak numbers — just reliability"
It sounds like he's still fiddling with it, but Accelerated Performance seems to be on the right track toward turning the BRZ into the nasty turbo street fighter Subaru's repeatedly said they're not going to build.
