For this reason, we build all of our EJ20’s as a hybrid setup: Using the EJ20 cylinder heads on an EJ25 short block\/crankcase. The two are compatible using special thicker gaskets, with no modifications needed to the heads themselves. This setup allows you to make big power reliably. Check out our EJ20\/EJ25 Hybrid Short Back Installation Kit for all components needed to make this setup work.  \u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eWant to know more about why we exclude certain upgrades form our engines?\u003c\/h3\u003e\n\u003ch4 style=\"text-align: center;\"\u003e\n\u003ca rel=\"noopener\" title=\"Everything you need to know about your Subaru Engine\" href=\"\/blogs\/tech\/everything-you-need-to-know-about-your-subaru-engine\" target=\"_blank\"\u003eClick here\u003c\/a\u003e to check out our blog all about Subaru engines.\u003c\/h4\u003e","brand":"Crawford Performance","offers":[{"title":"450whp\/540bhp (S2) \/ OEM (8.2:1)","offer_id":47258656604400,"sku":"CSS2P","price":799.99,"currency_code":"USD","in_stock":true},{"title":"550whp\/540bhp (S3L-X) \/ OEM (8.2:1)","offer_id":47258656637168,"sku":"CSS3LP","price":799.99,"currency_code":"USD","in_stock":true},{"title":"600+whp\/720+bhp (S3L-X FSR) \/ OEM (8.2:1)","offer_id":47258656669936,"sku":"CSS3FSR","price":799.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/9032\/0880\/files\/crawford-performance-crawfordspec-forged-pistons-sti-internals-ej257crawford-performance-3789295.jpg?v=1753975052"},{"product_id":"2004-2006-subaru-forester-xt-air-oil-separator-v2-crawford-performance","title":"2004-2006 Subaru Forester XT Air Oil Separator V2","description":"\u003ch2 style=\"text-align: center;\"\u003e2004-2006 Subaru Forester XT Air Oil Separator V2\u003c\/h2\u003e\n\u003ch3 style=\"text-align: center;\"\u003eCrawford Performance Air Oil Separator: The Subaru Original\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ch4\u003eNot a Catch Can - Closed Loop and Maintenance Free\u003c\/h4\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ch4\u003eConsume Less Oil\u003c\/h4\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ch4\u003eExtend the Life of your Engine\u003c\/h4\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ch4\u003eReduce Detonation and Risk of Engine \/ Ringland Failure\u003c\/h4\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ch4\u003eReduce Fuel Dilution and Subsequent Power Loss\u003c\/h4\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\n\u003cstrong\u003eOil pooling in your intake? \u003c\/strong\u003eStop the oil from ever getting there with the Crawford Air Oil Separator.\u003c\/h3\u003e\n\u003cp\u003eThe Crawford Performance Air Oil Separator (AOS) is the original solution to Subaru's notorious oiling system issues.

For this reason, we build all of our EJ20’s as a hybrid setup: Using the EJ20 cylinder heads on an EJ25 short block\/crankcase. The two are compatible using special thicker gaskets, with no modifications needed to the heads themselves. This setup allows you to make big power reliably. Check out our EJ20\/EJ25 Hybrid Short Back Installation Kit for all components needed to make this setup work.  \u003c\/p\u003e\n\u003ch3 style=\"text-align: center;\"\u003eWant to know more about why we exclude certain upgrades form our engines?\u003c\/h3\u003e\n\u003ch4 style=\"text-align: center;\"\u003e\n\u003ca href=\"\/blogs\/tech\/everything-you-need-to-know-about-your-subaru-engine\" target=\"_blank\" title=\"Everything you need to know about your Subaru Engine\" rel=\"noopener noreferrer\"\u003eClick here\u003c\/a\u003e to check out our blog all about Subaru engines.\u003c\/h4\u003e","brand":"Crawford Performance","offers":[{"title":"450whp\/540bhp (S2) \/ OEM (8.2:1)","offer_id":47258689536240,"sku":"CSEJS2","price":799.99,"currency_code":"USD","in_stock":true},{"title":"550whp\/540bhp (S3L-X) \/ OEM (8.2:1)","offer_id":47258689569008,"sku":"CSEJS3","price":799.99,"currency_code":"USD","in_stock":true},{"title":"600+whp\/720+bhp (S3L-X FSR) \/ OEM (8.2:1)","offer_id":47258689601776,"sku":"CSEJS3FSR","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/9032\/0880\/files\/crawford-performance-crawfordspec-forged-pistons-wrx-internals-ej20ej255crawford-performance-1796435.jpg?v=1791508748"},{"product_id":"crawford-built-subaru-short-block-sti-ej257-2004-2021-up-to-770-hp","title":"Crawford Built Subaru Short Block STI EJ257 2004-2021 UP TO 770-HP","description":"\u003cp\u003e\u003cstrong\u003eBuilt to order.\u003c\/strong\u003e This motor is built to order in our shop — not pulled off a shelf.
