The most likely sources are wrecks, auction cars, backyard sales, and, unfortunately, theft totals. The larger K24 series can be found in the Accord from and others.

One of the best possible combinations of cost and horsepower, the G23 engine swap in a Honda Civic is not for everyone.
Gone are the easy bolt in and swap guides, because most of this engine build will require some serious planning and engine work. This is a frankenstein of Honda engines, made up of several different Honda engine components.
The use of a SOHC 2. People with the proper knowledge and patience and build an awesome G23 that delivers more power and torque than the K series engine, at a fraction of the cost. When installing an upgraded clutch, it's a good idea to step up your clutch master cylinder like this unit.
It's designed to deal with the high pressure nature of your pressure plate in the 2. Where most K series engine swappers are going over 7, dollars in parts and components, the right G23 can be built for well under 2, dollars.

And to understand this, you have to understand the On Board Diagnostics part of engine swapping and what it means to you and your car.
What generation ECU is in my Honda? Each generation of On Board Diagnostics include more and more in the way of emissions controls and sensors that may or may not have to swapped over to your chassis.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 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. However, Hasport has stepped up once again to lead the industry.
Additionally, by mid-summer, they should have the ''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 thanAccords made every year sincethese engines are pretty much everywhere. The Accord is your source for a cheap manual transmission too. 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. 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.
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. Physically performing this swap with my own two hands wasn't so I could put wrench to bolt, but rather to try and help readers out when they go to do a swap that's really not commonplace just yet. Since we're not using RSX-S stuff, there are many new parts, and in typical Honda fashion, many things are interchangeable.
On the flip side, there are some other parts that aren't so compatible. The Swap The first thing you're going to stumble on is the engine.The B series swap is one of the most common Honda swaps.
Most people are unaware of another easy, but not quite as common engine swap. The H22A Prelude engine swapped into an Accord. Why is this an easy swap?
If the Accord engine fit in the Prelude, then why not put a more desirable Prelude engine into the Accord? Mechanically, it is a very easy swap. Electrically it is more difficult unless you can source a conversion harness.
Writing a how-to is more than I was willing to undertake for this write-up. This leaves you with two options: Modify the Accord harness to work with the new engine or find a conversion harness. The H22a swap is much less common due to the popularity of utilizing K-Series engines for swaps. Careful cutting and splicing is necessary to reroute the wires to the distributor.
Keep this in mind when planning your swap. This chart will provide you with the info you need to do a similar swap. This table provides the wiring pairing to splice the distributor wiring. I only have the wiring mapped out for the H22a equipped with an internal ignition coil. This is exactly how I wired the distributor and it worked flawlessly.
You may want to twist the wires and wrap them in tin foil to repair the shielded wiring that leads to the distributor. The other prelude mounts will NOT work.
K24 SWAP IN 2000 ACCORD
A little experimenting always goes a long way.

The two engine variations that we specifically support are:. We will just call these two K20 and K24 from here on for the purposes of this article. There are many other Honda K engines out there.

The Honda K series transmission is an upgrade over the Toyota C series transmission and it bolts directly to the Honda K engine of course so we use them in all of our swaps.
This removes the immobilizer making it usable plus adds full tuning capability via laptop. Works for K20 and K24 engines.
Any other engine and charging harness will NOT work. Engine: The K20 comes with a cable style throttle body, all set.

Amack New Member. Nobody really uses this motor because this is a very difficult swap to do because of the atts system that this motor has. The best thing for you to do is to get a complete swap and buy the Type S pistons and cams and put in that motor. Really this is a cheaper option and you will have the same hp as a H22a Type S and possible to pull a little more power with a good tune.
I have a 94 Accord coupe with an H22a in it and when the funds get right I am planning to buy type s cams and pistons as well. Those motors are running at least 4, Buying the base and putting the cams and pistons is the best thing to do all around and much less of a headache. Amack said:. The base model of the Prelude did not. If you get a non-SH there should not be any problems other than the basic swap related difficulties.

MR2-S Honda K20 K24 Swap
It's even arguably one of the better looking Accords ever made. In spite of its achievements as a utilitarian consumer vehicle, though, the Honda rarely gets a whole lot of respect outside of its native suburbanite habitat. A simple engine swap with a modern K-series engine and that Accord could be back on the "most desired" list. Not any K series, though, just the 2. In the heavier Accord, however, this may actually be the best engine to get. You may be wondering to yourself, why would I put a hp K24 in my fifth gen.
Indeed the marginal power increase doesn't seem to merit the expense. Well, there are a couple of reasons. First, the K24 will have more torque everywhere in the powerband thanks to the cam phasing found in iVTEC motors.
Second, that F-series is pushing ten years and could be nowhere near what it used to be.
Finally, K24's are starting to pile up in junkyards. To simplify production, it appears the head on the A2 the real 3-lobe VTEC and the A4 economy VTEC are very similar when it comes to combustion chamber size, port area, and valve dimensions. This suggests that if someone would just make a big cam for the non-A2 heads we should see pretty good power from lesser K24 engines.
That somebody will soon be Skunk2. Preliminary testing has shown over wheel hp for these engines with minor modifications. Now that you're interested in a K24 for your CD Accord, here's what else you'll need.
Finally, like any K swap, you'll need the shifter box and cables from the Accord or TSX the engine came out of. Power steering works simply by rerouting a line to the other side of the car remember: the K-series is oriented degrees from an F engine. Air conditioning is possible, but only with a tubular front crossmember Full-Race makes one and a pair of custom made hoses. The stock radiator works but takes some hose trickery, so for this swap, Hasport used the radiator from an ' Civic Si since it has in's and out's on the correct sides.
It may seem like a lot of things to get, but if you want more power out of your CD-chassis Accord, or if you just want to have one of the coolest fifth gens.
