{"product_id":"vtec-piston-lock-pins-for-d-series","title":"VTEC Piston Lock Pins for D Series","description":"This kit includes 8 pins designed to lock the VTEC system on all D Series VTEC engines. Constructed from lightweight titanium, these pins offer a significant 35% weight reduction compared to stock components, with each rocker assembly pin weighing only 5.8g.\n\nThe VTEC solenoid can remain installed, or a block-off plate can be used. The LMA's (Lost Motion Assemblies) can also be retained or removed depending on the specific setup. This VTEC elimination strategy provides several benefits, including reduced weight in the valvetrain, which aids in maintaining proper valve motion and lessens the likelihood of valve float during extreme high-RPM operation. It also eliminates potential issues related to VTEC solenoid wiring or the solenoid itself that could cause the engine to drop out of VTEC during a run. Furthermore, disabling the VTEC system redirects oil pressure to the engine's bottom end and camshaft spray bars, potentially increasing their effectiveness.\n\nThis pin kit is compatible with a range of Honda and Acura models, including the 1986–1987 Honda Civic Si Hatch, 1988-2005 Honda Civic, 1988–1995 Honda Civic Si, 1984–1987 Honda CRX, 1985–1991 Honda CRX Si, 1993–1997 Honda Del Sol, 1993–1995 Honda Del Sol Si, and 1986–1989 Acura Integra.","brand":"Speed Factory","offers":[{"title":"Default Title","offer_id":52866373714232,"sku":"SF-02-043","price":42.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687687797.webp?v=1787906910","url":"https:\/\/store.motormia.co\/products\/vtec-piston-lock-pins-for-d-series","provider":"MOTORMIA","version":"1.0","type":"link"}
