Car Description:
Although I purchased this car used, all of the items listed below were done by me. When I acquired this STI it had a cobb stage 1 tune w/ cold air intake.
Meet my fifth Subaru, aptly named "Gaparu". Every detail of this build was curated for uniqueness, steering away from the off-the-shelf solutions. While many might opt for a standard IAG setup, I strived for distinction. Instead of picking up an IAG Stage X build, I joined hands with Kings Performance to craft something truly singular, taking inspiration from the iconic "White Bullet STI". We use several IAG products, but that's where it stops.
Gaparu isn't just about looking good; it's about performance in every scenario. Whether it's a drag strip, an HPDE session, a track day sprint, or time attacks, this vehicle is designed to outperform. Its essence? Being unparalleled, whether on a straight stretch or a sharp turn. Whether it's an unplanned sprint on a secluded road or outpacing high-end sports cars at track days, Gaparu stands tall.
Every component, from the fully adjustable coilovers to every suspension component being adjustable, emphasizes precision and performance. Comprehensive chassis reinforcement comes courtesy of Cusco, while the custom-engineered block started with an IAG closed deck, and was further customized by us utilizing ACH for all additional Bore, sleeving and honing. This allowed it to fit and meet the demand for our specific pistons, rods, billet cam, and crankshafts. The heads were custom done for some of the highest flowing CFM heads on an EJ257. I cannot stress how well done the block/heads were by Advanced Cylinder Heads to Kings Performances specifications based on my vision for this build. The masterpiece that emerged is nothing short of splendid.
It's worth noting that Willy from Kings Performance is no stranger to excellence, holding numerous world records across various automotive disciplines. Their expertise made them the quintessential partner for this build, ensuring Gaparu is not just another car, but a testament to engineering and passion.
