If you can dream it, you can build it! EFI Logics may be the first US Company to tackle a big power build on Subaru’s funky new 2010 Legacy GT. Because of the new turbo design being very different than previous versions, there are few aftermarket parts for the new LGT. Undaunted, the crew at EFI logics felt that they could hit their customer’s desired 300whp goal while still using the stock turbo location and maintaining a very stock-looking and daily-drivable car. The COBB Tuning AccessPORT was the engine management solution chosen for this build. While map selections are currently limited to Stage1, AccessTUNER Pro and AccessTUNER Race let ProTuners and enthusiasts create their own calibrations for bigger power gains!

This build is all custom with very few off the shelf parts. The turbocharger is a custom made unit by BNR Supercars with the guts of a TD05 shoved into the stock VF52 turbo housing and is fed by an EFI Logics custom intake using a KSTech MAF housing. Boost pressure is vented via a Forged blow off valve between shifts and is mounted to an EFI Logics custom front mount intercooler. Boost control is done via a Grimmspeed 3-port unit. The exhaust features a BMC downpipe feeding an Invidia Q300 catback. The injectors are 750cc Deatschwerk topfeeds fed by a Walbro 255lph in-tank pump. Power is transmitted to the transmission via an ACT HD Street clutch. Tuning is accomplished with the COBB Tuning AccessPORT and the combination is good for 318whp and 348wtq on pump fuel.

While there are currently no parts readily available for these vehicles, adventurous owners are still able to make power with some creativity and of course, the COBB Tuning AccessPORT!
