Professional Selection Required
Head unit only. Brackets, drive system, pulley, belt, intercooler, bypass valve, inlet/discharge tubing, fuel system and calibration are not included. Final selection must be matched to engine displacement, base horsepower, target boost, impeller speed, drive ratio, compressor rotation and intended use.
Special-order race components are non-cancelable once processing begins and are not returnable. Contact SMGspeed before ordering if any configuration detail is uncertain.
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
