The stock cast internals handle 500–600whp reliably, but beyond that the rods and pistons become the limiting factor. Our B58 forged internals kit replaces the stock components with race-grade forged units capable of handling serious power builds on pump fuel, E30, or full E85.\u003c\/p\u003e\n\u003cp\u003eWhat's Included:\u003cbr\u003eForged connecting rods — 4340 aircraft-grade steel, I-beam design\u003cbr\u003eForged pistons — CP or equivalent specification, 82.00mm bore\u003cbr\u003eCompression Ratio: 10.2:1\u003cbr\u003eCompression Height: 33.20mm\u003cbr\u003eARP rod bolts included — 220,000 PSI rated\u003cbr\u003eWrist pins — standard or heavy duty (HD recommended for 850HP+ builds)\u003cbr\u003eBalanced and matched set — within ±1.5g\u003cbr\u003eRing set included\u003c\/p\u003e\n\u003cp\u003ePower Capability:\u003cbr\u003eStandard configuration — 1,000HP capable\u003cbr\u003eWith HD wrist pins — up to 1,500HP capable\u003cbr\u003eSuitable for pump fuel, E30, E85, and methanol builds\u003c\/p\u003e\n\u003cp\u003eCompatible Vehicles:\u003cbr\u003eToyota GR Supra — A90 (2019–present)\u003cbr\u003eBMW Z4 M40i — G29 (2018–present)\u003cbr\u003eBMW 340i — F30\/F31\/F34 (2015–2019)\u003cbr\u003eBMW M340i — G20\/G21 (2019–present)\u003cbr\u003eBMW 440i — F32\/F33\/F36 (2016–2019)\u003cbr\u003eBMW M440i — G22 (2020–present)\u003cbr\u003eBMW M140i — F20\/F21 (2016–2019)\u003cbr\u003eBMW M240i — F22\/F23 (2016–2021) · G42 (2021–present)\u003cbr\u003eBMW 540i — G30\/G31 (2017–present)\u003cbr\u003eBMW 640i — G32 (2017–present)\u003cbr\u003eBMW 740i\/Li — G11\/G12 (2016–present)\u003cbr\u003eBMW 840i — G14\/G15\/G16 (2019–present)\u003cbr\u003eBMW X3 M40i — G01 (2017–present)\u003cbr\u003eBMW X4 M40i — G02 (2018–present)\u003cbr\u003eBMW X5 xDrive40i — G05 (2018–present)\u003cbr\u003eBMW X6 xDrive40i — G06 (2020–present)\u003cbr\u003eBMW X7 xDrive40i — G07 (2018–present)\u003cbr\u003eAll B58 variants — B58B30M0, B58B30M1, B58B30O1\u003c\/p\u003e\n\u003cp\u003eWhy Upgrade the B58 Internals?\u003cbr\u003eThe stock B58 uses cast connecting rods and pistons. While durable at moderate power levels, cast components crack under sustained high-boost operation. At 600–700whp+ the rods are the first failure point — typically bending or snapping under high-RPM boost spikes. Forged internals eliminate this risk entirely, giving you a foundation that can handle whatever turbo and fuelling combination you choose to run.\u003c\/p\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/bmw-n55-forged-internals\"\u003eBMW N55 Forged Internals — 1,500HP Rated | Pistons, Rods, Rings — $4999.00\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@type\":\"BreadcrumbList\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Shop\",\"item\":\"https:\/\/ypgmotorsport.com\/collections\/all\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"BMW B58 Forged Internals — 1,500HP Rated | Pistons, Rods, Rings\",\"item\":\"https:\/\/ypgmotorsport.com\/products\/bmw-b58-forged-internals\"}]}\u003c\/script\u003e\n\u003cdiv class=\"product-faq\" style=\"margin-top:24px;border-top:1px solid #e0e0e0;padding-top:20px;\"\u003e\n\u003ch3 style=\"font-size:18px;font-weight:bold;margin-bottom:16px;\"\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cdetails style=\"margin-bottom:12px;\"\u003e\u003csummary style=\"font-weight:600;cursor:pointer;padding:8px 0;\"\u003eHow much does the BMW B58 Forged Internals | Rods \u0026amp; Pistons cost?\u003c\/summary\u003e\u003cp style=\"padding:8px 0 8px 16px;color:#555;\"\u003eThe BMW B58 Forged Internals | Rods \u0026amp; Pistons is $4999.00 through YPG Motorsport with free worldwide shipping.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails style=\"margin-bottom:12px;\"\u003e\u003csummary style=\"font-weight:600;cursor:pointer;padding:8px 0;\"\u003eAre these drop-in replacements for the B58?\u003c\/summary\u003e\u003cp style=\"padding:8px 0 8px 16px;color:#555;\"\u003eYes.
