The end result, 160 hp and 161 lb/ft of torque from the Honda Accord K24A4. You've seen it
In the previous "K-Swap For Less" article (April issue), I highlighted some simple ways to cut the cost of installing K-power. After gathering information on pricing and parts availability, I had estimated about $2,500 coming off the total cost by utilizing a K24 motor from an Accord/Element/CRV, instead of the usual K20A2 from an RSX Type S. This time around I'm documenting the actual swap process, but instead of just watching, taking notes, and snapping a few pictures, I thought I'd actually perform the swap as if I'd just read the original story.
Of course, the downside of a K24 is that you won't get that infamous 200 horsepower, but you would get a K-swap, and lately, just having that is heading toward the top of most enthusiasts' lists. Now that more aftermarket support for the K24 has surfaced, as well as the excellent torque that the 2.4L offers, this budget swap can reap outstanding rewards over a D, B, or even H series swap.
The problem with doing a 160 hp/160 torque K24 swap is that the manual transmission from the Accord has a different type of bell housing compared to the RSX and EP3. And at the time, all swap mount kits would only work with the RSX/EP3 trannies.
However, Hasport has stepped up once again to lead the industry. They now have a kit for the EH/DC chassis that will let you use the Accord five-speed, and even the TSX six-speed. Additionally, by mid-summer, they should have the '96-'00 version available as well. At that time, Hasport will also have a dual height version similar to the EKK2 available.

Here's the quick breakdown of this new swap: you'll be using the standard K24, (not the real VTEC one, but the other one). With more than 300,000 Accords made every year since 2003, these engines are pretty much everywhere. High mileage units at yards that have a large inventory can be as low as $300. The standard K24 is in the 2003-up Accord and Element, and the 2002-up CRV.
The Accord is your source for a cheap manual transmission too. The units from the Element and CRV are set up for AWD, so their cases are completely different once again. But the Accord sold in decent numbers with a manual transmission, so you can probably find them from $300-$500, depending on condition. The bonus to the Accord transmission is its shifter box and cables. That's at least half the cost of RSX stuff.
Using Accord parts is essentially the cornerstone to this swap, and where the major savings come in. But we found a few other savings thanks to Hasport and the forums. Up first is a bracket set from Hasport, which allows you to use the alternator from a '96-'00 Civic as not only the alternator for the K24, but also the belt tensioner in a non-power steering and A/C-equipped swap. This is huge because the aftermarket solutions, even an ep3 idler, can cost $100 or more. On our '95 Integra four-door, we wanted to keep the power steering, so we didn't use this. But because we kept the K's power steering pump, we could also keep the original tensioner.
Next was the fuel supply system. The K24 doesn't use a fuel return from the fuel rail, but the Integra does. What's usually done is a full blown kit, from someone like K-Tuned, that includes lines, AN fittings on braided hose, a billet fuel rail, and billet fuel pressure regulator (FPR). No doubt, something like this is going to look incredible, but it could also top $500. Keeping our budget in mind, we went the eBay route. A simple Chinese FPR with all push-on line connections is less than fifty bucks shipped. I'd never use one of these things for a turbo engine, but for a constant pressure setup like the K24 requires, it's a perfect fit. By adding just one twelve-inch piece of fuel line, we had the entire system connected with parts that were already under the hood.
A few other pennies were pinched with the clutch line, power steering hose and more, but the captions will display those. The rest of the story, however, revolves around the old saying "the devil in the details."
