Used Acura Engines for Sale – Tested, Warrantied & Shipped Worldwide

Acura engines have a well-earned reputation for going the distance – it’s not unusual to see a K24 or J35 crossing 200,000 miles with nothing more than routine maintenance. So when one does finally need replacing, it’s usually from an accident, a timing belt neglected too long, or plain bad luck, not a design flaw. If you’re shopping for a used Acura engine for a TL, TSX, MDX, RDX, or ILX, here’s what’s actually worth knowing before you buy.

We source and test used Acura engines – most of them cataloged under their shared Honda part numbers, since Acura and Honda engines are frequently identical hardware – and back them with a written warranty.

Acura Engine Families

Engine	Used In	Displacement	Layout	Notes
K24A2 / K24A4	TSX, CR-V (shared with Honda)	2.4L	Inline-4, DOHC i-VTEC	Timing chain, not belt – genuinely low-maintenance and durable
J35A / J35Y	TL, MDX, RDX (V6 trims)	3.5L	SOHC V6, VCM on later variants	VCM (cylinder deactivation) can cause rough running if lifters wear; well documented fix
J37A	TL SH-AWD, ZDX, MDX	3.7L	SOHC V6	Higher output version of the J-series, strong bottom end
K20Z / K24Z	ILX, TSX (later years)	2.0L – 2.4L	Inline-4, DOHC i-VTEC	Direct descendant of the K-series race-proven architecture
C32A / C35A	NSX, RL (older, NA only)	3.2L – 3.5L	V6, some VTEC variants	Older platform, parts availability is thinner than newer J and K series

We don’t have a dedicated Acura-badged listing live at the moment, but because so much of this hardware is shared with Honda’s Accord, CR-V, and Odyssey lineups, we can usually source a matching K-series or J-series engine on request – reach out with your exact engine code and we’ll check current stock.

Why Acura and Honda Listings Overlap

An Acura TSX and a Honda Accord of the same generation frequently ran the exact same K24 engine, just with different tuning and badges. A TL’s J35 is closely related to the V6 in a Honda Odyssey or Pilot. This matters for sourcing because it massively widens the pool of usable donor engines – you’re not limited to searching wrecked Acuras specifically, which tend to be a smaller and pricier pool than searching Honda donors with the same engine code.

What We Check Before Listing

• Compression testing on all cylinders
• VCM lifter condition on J35/J37 V6 engines with cylinder deactivation, since worn VCM lifters are the most common complaint on these engines
• Timing chain wear on K-series and later J-series units (both are chain-driven, not belt-driven, which is part of why they last so long)
• Oil condition for metal content and sludge buildup
• VTEC solenoid function, checked during a cold and warm start cycle where possible
• Mileage verification from donor vehicle records

Honestly, K-series and J-series engines pass these checks at a higher rate than most other brands we work with. They’re just well-built engines. Most of what we reject comes down to neglected maintenance on the donor vehicle, not a weakness in the engine design itself.

The VCM Question (J35/J37 Buyers)

Variable Cylinder Management, Honda’s cylinder deactivation system on later J-series V6s, gets a mixed reputation online. In practice, the issue is almost always worn rocker arm assemblies or a failing spool valve, not a fundamental design flaw, and it’s a well-documented, fixable issue with known parts. If you’re buying a used J35 or J37, ask whether the VCM components have been inspected or replaced – we note this on every listing because it’s the single most relevant thing to know about buying one of these engines used.

Compatibility Notes

• K24 variants differ meaningfully between applications (K24A2, K24A4, K24Z) – head design and compression ratio aren’t identical across all of them, so match the exact suffix, not just “K24”
• J35 engines built for transverse, front-wheel-drive-based platforms (TL, MDX) are not interchangeable with J-series engines from other layouts without significant adaptation
• Older C-series engines (NSX, RL) are a separate architecture entirely and don’t share parts with the later J or K families

Warranty

Every used Acura engine we source ships with a written warranty covering internal mechanical failure – a spun bearing, cracked block, or similar issue unrelated to installation. VCM components, sensors, and accessories are covered only as part of a complete package purchase, and damage from running without proper fluids after install isn’t covered. We’ll confirm exact terms for your specific engine code before you order.

Shipping

We ship worldwide, palletized and secured with sealed ports to keep contaminants out during transit. Ocean freight is the standard, economical option for international orders; air freight is available for faster turnaround at a higher cost. We handle the commercial invoice and documentation needed for customs on our end – import permits for used engine parts vary by country and are the buyer’s responsibility to confirm locally.

Buying Checklist

1. Match the exact engine suffix (K24A2 vs K24A4, for example), not just the displacement
2. Ask about VCM lifter condition if you’re buying a J35 or J37
3. Get a compression test result before committing
4. Check whether a Honda-badged donor with the same engine code is an option – it often widens availability
5. Get warranty terms in writing

Frequently Asked Questions

What mileage are used Acura engines typically at when you source them?
It varies by donor, but K-series and J-series units commonly come from vehicles in the 60,000-120,000 mile range, since these engines are often still running well even at that point – the donor vehicle is usually totaled for body damage, not engine failure.

Can I use a Honda Accord engine in my Acura TSX?
Often yes, if the engine codes match exactly – many TSX and Accord trims shared the same K24 variant. We’ll confirm against your VIN before you order.

Is VCM something I should avoid, or is it fine on a used engine?
It’s fine as long as the lifter and spool valve components have been checked. It’s a known, well-understood system at this point, not a reason to avoid a J35 or J37 outright.

Do you sell just the engine, or engine plus transmission?
Depends on the source vehicle and listing. Let us know what you need and we’ll tell you what’s currently available as a combo versus engine-only.
