Description

The Acura TSX K24A2 is a JDM Honda K24A engine replacement, specifically the RBB-2 model, which is equivalent to the K24A2. This engine features 3-lobe i-VTEC technology and comes as a complete and extremely clean motor set with approximately 56,000 miles. It has been compression tested at 180 PSI across all four cylinders. This engine requires the use of original intake and exhaust manifolds along with all necessary accessories. Please ensure you conduct your own research to confirm fitment for your specific vehicle, as Top Tier Japan LLC does not provide installation instructions or fitment guides. All motors sold are clean, complete, and in 100% working order.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
