Tap a vehicle to see every unit we have for it. Trim, transmission and emissions equipment vary within a model year — text us your VIN and we will confirm before you order.
Contents vary unit to unit — the photos and description on this page show what this listing type ships with. Anything missing you need, ask before you order.
Units are strapped to a pallet and crated. Have a forklift or a way to unload at the receiving end, or choose liftgate service. Questions on a quote before checkout? Text (469) 570-4113 with your zip.

JDM 2004–2008 Honda / Acura TSX K24A 2.4L DOHC i-VTEC Engine — RBB-3 Head, High Compression, ~200HP — Approx. 60,000 Miles
Genuine Japanese-domestic-market K24A 2.4L DOHC i-VTEC inline-four with the desirable RBB-3 head stamp, imported directly from Japan by JDM Alliance. The RBB is the sought-after K24 head — higher compression and better flow than the U.S.-market K24 units — which is why it's the go-to base for K-swap builds. Serial K24A-5609921.

What's included
Please note: the transmission is not included. Although parts of it appear in some photos, it is not part of this listing. You'll re-use your original intake manifold, exhaust manifold, ECU, wiring harness and accessories. Anything else visible in the photos is included unless noted otherwise.
Fitment
Depending on your application this may install as a long block with your original external accessories transferred over. Swapping a K24 into a non-K chassis requires mounts, axles, a compatible ECU and other supporting parts. Confirm fitment with your mechanic before ordering — call or text us and we'll help you check.
Warranty & returns
This is a performance engine — an upgrade over the engine it replaces in most applications — and it carries our 30-day performance-engine warranty and a 30-day return window, not the 90-day start-up warranty that applies to like-for-like replacement engines. Full terms at jdm-online.com/pages/warranty.
