The manifold and downpipe are welded up here, which lets us keep the runners tight to the head and prioritize the wastegate so exhaust energy reaches boost control before it hits the turbine. We run the Turbosmart GenV HyperGate45 to keep that control honest under load.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe fittings and block adapters are machined in-house. Oil return, oil feed, the catch can fitting, and both coolant block fittings are cut for the B58, so they seat clean without stacking adapters to make something generic fit. The drain line, the 10AN oil drain outlet flange, and the 22\" stainless feed line are built to the kit, not adapted to it.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eWe don't modify the compressor housing to make a turbo fit. That's on purpose. You can swap turbos at the track without cutting or welding, so when your combo changes the kit doesn't fight you.\u003c\/p\u003e","brand":"KLM Race","offers":[{"title":"No Turbo","offer_id":43762038374474,"sku":"KLM-100","price":6170.55,"currency_code":"USD","in_stock":true},{"title":"Precision 6466","offer_id":43762038407242,"sku":"KLM-101","price":8422.66,"currency_code":"USD","in_stock":true},{"title":"Precision 6870","offer_id":43762038440010,"sku":"KLM-102","price":8769.8,"currency_code":"USD","in_stock":true},{"title":"Precision 7275","offer_id":43762038472778,"sku":"KLM-103","price":8816.28,"currency_code":"USD","in_stock":true},{"title":"Precision 7675","offer_id":43762038505546,"sku":"KLM-104","price":8869.27,"currency_code":"USD","in_stock":true},{"title":"Garrett G35-1050","offer_id":43762038538314,"sku":"KLM-105","price":8980.6,"currency_code":"USD","in_stock":true},{"title":"Garrett G40-1150","offer_id":43762038571082,"sku":"KLM-106","price":9080.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/5431\/9690\/files\/6a16c7b9-KLM-A91-6-Port-Full-Kit-scaled.jpg?v=1774364132"},{"product_id":"klm-gen-1-b58-stage-2-engine-build-1-200-whp","title":"KLM Gen 1 B58 Stage 2 Engine Build (1,200 WHP)","description":"\u003cp\u003e\u003cstrong\u003eYou will receive an email after placing this order to confirm freight and final shipping cost.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eStage 2 is where the real upgrades start.

Pistons step up to a higher rated CP-Carrillo spec, and the head gets actual GSC intake and exhaust valves and Kelford or GSC cams instead of a stock valvetrain.
