The direct injection pump drive is modified to inject more fuel. We also port the cylinder head to ensure maximum flow at high RPM with larger turbochargers.\u003c\/p\u003e\n\u003cp\u003eThe S63 engine is not designed to have large increase in boost. CarBahn has designed a high-performance engine to handle very high outputs by utilizing higher quality racing components. This engine includes higher quality racing Forged Carrillo connecting rods, CP forged pistons and CarBahn high-performance valve springs, ported head High performance direct injection cam drive. This Engine includes a complete rebuild with a valve job, timing chains, chain guides, tensioners, water pump thermostat, new bearings, seals and gaskets.\u003c\/p\u003e\n\u003cp\u003eThe stock high compression ratio is high for CAFÉ. (Corporate average fuel economy). However, this increased compression limits engine performance with higher boost setting by decreasing the size of the fuel air charge in the combustion chamber and by forcing the ignition timing to retard far below MBT (mean best timing). The CarBahn engine has .5 less compression to optimize the engine for the increased boost. If this an emissions legal street car the lowered compression has the added benefit of reducing catalyst inlet temperatures and improved drivability on pump gas.\u003c\/p\u003e\n\u003ch5\u003eCarBahn History:\u003c\/h5\u003e\n\u003cp\u003eSteve Dinan has been building high performance and racing engines for BMW’s since 1977! Winning 12 racing championships including 3 prototype championships and two - 24 hours of Daytona. The same engine shop that builds the racing engines also builds the street car engines. This group of talented engineers, Engine machinist and engine builders has built hundreds of engines. From rebuilds to developing engines making over 625hp on an S65 and over 740hp on an S85.\u003c\/p\u003e\n\u003cp\u003eWe have the record for the most powerful S55 engine producing over 1,000hp and S63 engines producing over 1,300hp!\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/WSHusoVQm8o?si=kichssZ9qDH35PTY\" height=\"315\" width=\"560\" allowfullscreen=\"\" referrerpolicy=\"strict-origin-when-cross-origin\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"CarBahn","offers":[{"title":"Stock Compression","offer_id":44404817330384,"sku":"CB263-6002","price":23995.0,"currency_code":"USD","in_stock":true},{"title":"Low Compression","offer_id":44404817363152,"sku":"CB263-6002-LC","price":23995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/5886\/1520\/files\/CBB463-6003_44907644-271d-4737-937c-252e0bc51882.jpg?v=1738241764","url":"https:\/\/motorworkswest.shop\/products\/stage-2-s63-high-performance-engine-bmwm5-m6-x5m-x6m","provider":"Motor Works West","version":"1.0","type":"link"}
