The bolt-on designation means this is a kit designed for installation without engine removal or machining. All components are designed to work within the FA20's existing architecture. Professional installation and a proper ECU tune are required.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e\n\n\u003ch4\u003e\u003cstrong\u003eSpecs \u0026amp; Highlights\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eComplete turbo conversion kit for FA20\u003c\/li\u003e\n  \u003cli\u003eBolt-on installation without engine removal\u003c\/li\u003e\n  \u003cli\u003eHKS turbocharger\u003c\/li\u003e\n  \u003cli\u003eIntercooler, piping, oil feed and return lines included\u003c\/li\u003e\n  \u003cli\u003eSignificant power increase over naturally aspirated baseline\u003c\/li\u003e\n  \u003cli\u003eRequires professional ECU tune after installation\u003c\/li\u003e\n  \u003cli\u003eFitment: 2013-2021 Scion FR-S \/ Subaru BRZ \/ Toyota 86\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\n\n\u003ch4\u003e\u003cstrong\u003eGTII-RS 7460 Turbo, 47mm Compressor, 7 psi Standard\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eThe FA20 bolt-on turbo kit uses a GTII-RS 7460 turbocharger with a 47mm compressor wheel, sized for the FA20's airflow envelope and street use requirements. Boost pressure at standard configuration is approximately 7 psi (0.48 bar), producing approximately 250–270 whp on a properly tuned car versus the stock FA20's 197 whp. The front-mount intercooler core is air-to-air construction with an end tank volume calculated for the FA20's intercooler volume requirements. Oil feed line diameter is AN-4 (1\/4 inch) with a factory oil galley adapter.\u003c\/p\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/products\/00590933abf12e5bd6f991cace75de62.jpg?v=1697648520\" alt=\"HKS Bolt-On Turbo Kit - 2013-2021 Scion FR-S \/ Subaru BRZ \/ Toyota 86\" style=\"max-width:100%;height:auto;display:block;margin:20px 0;\"\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/products\/b1d558dfd34fb6a6d23a38116b24b577.jpg?v=1697648520\" alt=\"HKS Bolt-On Turbo Kit - 2013-2021 Scion FR-S \/ Subaru BRZ \/ Toyota 86\" style=\"float:left;width:40%;max-width:300px;height:auto;margin:0 20px 16px 0;\"\u003e\n\n\n\n\u003ch4\u003e\u003cstrong\u003eFA20 Compression Ratio and Boost Compatibility\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eThe FA20 in the FR-S and BRZ was designed with relatively conservative compression for a naturally aspirated application. Partially because the flat-four configuration and Subaru's history made the platform a logical candidate for forced induction from the start. The HKS turbo kit takes advantage of this by introducing boost to an engine that can handle it at moderate pressure levels without requiring internal modification at sensible power targets.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e\n\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/products\/53e6cd670b86d2c191821361cf855efc.jpg?v=1697648520\" alt=\"HKS Bolt-On Turbo Kit - 2013-2021 Scion FR-S \/ Subaru BRZ \/ Toyota 86\" style=\"max-width:100%;height:auto;display:block;margin:20px 0;\"\u003e\n\n\n\n\u003ch4\u003e\u003cstrong\u003eA Tune Is Not Optional — It Is Required\u003c\/strong\u003e\u003c\/h4\u003e\n\n\u003cp\u003eA proper tune is not optional, it is required. The FA20 on a stock tune with boost will run too lean and damage the engine. The kit includes the hardware but the tune is a separate service that must be performed by a qualified tuner on a dyno. Budget for the tune as part of the total project cost.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e\n\n\u003ch4\u003e\u003cstrong\u003eThe FT Breakdown\u003c\/strong\u003e\u003c\/h4\u003e\n\n\n\n\u003cp\u003eThe HKS Bolt-On Turbo Kit is the most significant power upgrade available for the FA20-powered FT86 chassis. Adding boost to a well-sorted naturally aspirated chassis transforms the character of the car while keeping its balance intact. The FA20 responds well to boost and HKS's turbo kit is engineered specifically for this application: not adapted from another platform. The FA20's 12.5:1 compression ratio in stock form is on the high end for naturally aspirated four-cylinders, which is why HKS sized the GTII-RS 7460 for 7 psi at standard configuration rather than the 12–15 psi you might see on a dedicated turbo engine. That conservative boost target is deliberate — it keeps the FA20's compression ratio manageable without requiring internal engine modification, and it is what makes the 'bolt-on' claim accurate rather than aspirational.\u003c\/p\u003e\n\n\u003cdiv style=\"clear:both;\"\u003e\u003c\/div\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":52621286539544,"sku":"HKS11001-KT001","price":1485.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/4514\/4856\/files\/9le0bp1isxqo_fe053daa-d0cf-4421-9854-ef90ac596d83.jpg?v=1788747970","url":"https:\/\/driveforges.com\/products\/hks-bolt-on-turbo-kit-2013-2021-scion-fr-s-subaru-brz-toyota-86-vmcc73","provider":"Drive Forge","version":"1.0","type":"link"}
