Hands On: Leland Kirton’s 2006 Subaru WRX STI

Photography by Ken Au


Like many young enthusiasts, Leland Kirton was amazed by Ken Block’s early gymkhana videos which featured his old Subaru WRX STI. “The unique styling, engine design and sound made it a must have for me,” Kirton reminisces. “As years went by my lust for the car grew, and I just kept saving my pennies until I was able to finally afford one. Now that I have owned one for quite a while, I find that I still have the same feelings towards it, which is an excellent sign that I made the right choice.”

Kirton fancies himself a hands-on tinkerer, and once he had the car in his possession, his ability to learn quickly and apply that knowledge took over. He bought a TIG welder, learned how to use it, and made use of those skills as his build got serious. After having an engine failure luckily repaired while still under warranty, he used the next engine build as an opportunity to push the limits.

He used his TIG welding skills to fabricate his entire turbo system, including intercooler piping and intake manifold, and did a full valvetrain upgrade.

After hours of research, he settled on a BorgWarner S362sx-e turbo for big power. He had a goal of 500 whp, and sure enough, he made almost exactly that, coming in at an impressive 505 whp on the dyno. “Whenever I choose a specific part, it’s always because I’ve done a copious amount of research and know for a fact that it will fit my build very well,” says Kirton. “Case in point would be my current turbo choice of the Borgwarner S362sx-e.”

In addition to his newfound TIG welding skills, Kirton also owns a custom pwder coating shop with his brother Taylor, which actually started as a result of Kirton’s personal work on his STI. “I originally wanted to start powder coating my own fabricated parts and then it just spiraled into a business,” Kirton exclaims. “We have now been going strong for over 2 years and are continuously building momentum!” Keep up the good work, Kirton!
