Building a Legacy

1 Posted by - March 7, 2017 - Features, Uncategorized

What is a Legacy?  To most, a Legacy is something you build and create during your life to benefit future generations.  This is not one of those things but it shares some similarities.  This is a Subaru Legacy GT which in a nutshell in the mature man’s WRX…or is it?  The Legacy from the factory features sleek and subtle body lines but it doesn’t scream performance sedan.  The GT’s come with turbocharged 2.5L (250 hp) from the WRX with either a 5 speed manual or automatic unless you got the Spec B model which came with Blistein suspension and a 6 speed.

Jonathan Morris, a native from Asheville, NC and owner of this beautiful Legacy is the mastermind behind the build.  He bought this car at age 19 but only because insuring a WRX or even an STi was a little out of the question but he knew that the Legacy made a little more power than the WRX and was a more refined machine versus the STi.

Because the Legacy shares the WRX/STi motor platform, simple bolt-ons and a good tune could reach the power Jonathan wanted to get to.  Initially, he wanted to install a front mount intercooler and an HTA35 turbo with some bigger injectors and stronger clutch to hold 350ish whp.  Unfortunately the factory setup “blew up” so it was time to get serious.  The current setup on pump gas is sitting right around 500 whp.

“I would like to thank Fasttech Motorsports in Knoxville, TN for the tuning and fabrication work on the turbo and charge pipe setup.  The rest of the work on the car was done by me, including  building the engine in my living room, which now has 40k hard miles on it.”
