Guide to Civic Engine Swaps"Engines that fit in the Civic" Show
Here is a list of engines our members have put or tried in their Civics, along with a pros and cons guide to each one. Some of the best and most impressive power upgrades include engine swaps, so rather than spending money on tuning up your engine see which of the following engines will help you to reach your power goals on your Civic. Engine swaps are a great way to bump up the power on your Civic and we've seen some pretty awesome conversions, turbocharged engines, and cross platform swaps. Popular engines suitable for Civic engine swap projects
Often when you've paid out for lots of modifications for your engine, sorted out the inherent problems, and finished the project you discover that you could have got similar power just by swapping the engine for a more powerful unit. A much simpler route to adding reliable power to your car, and in the case of many swaps on the Civic, are virtually a bolt in mod. Doing an engine swap can also give you a better base to work from for your tuning projects and by applying additional mods to this new engine, you can achieve a much higher power figure that you never could have done on the original unit. Swapping the engine is always a large task, and the complexity depends on the donor vehicle's generation compared with your own. Same generation swaps are easier. There are many swaps done that only gain around 10hp, but with other mods, the advantages add up with the new engine usually having more potential for tuning, or for example adding forced induction. This shows the importance of doing your research. Alternatives to engine swapsMany of the engine heads can be swapped out, so non VTEC heads can be swapped for better flowing and "higher compression" heads or for different cam profiles. The EX head will fit on the LX block without modification.For example, the LX and DX blocks are identical with the exception of the compression ratios, which are 9.9 and 9.5, respectively. If you intend to turbocharge, a lower compression ratio will be advantageous. Vtec is gained by putting an ex-head on the DX/LX bottom. The DX/LX engine has an advantage over the EX engine due to its lower compression ratio; when combined with Vtec, this results in significantly more air entering at higher RPMs. ECU tweaks and wiring for head/engine swapsGetting an EX ecu with an EX engine harness is one of your wiring possibilities when completing a change like this. Another option is to run the DX ECU with a Vtec controller hooked in to regulate the vtec system. Alternatively, if you wanted to spend a lot of money, you could purchase Kpro which gives more control over everything. With the Apexi V AFC2 digital fuel controller, you can utilize your existing ecu without having to have your key reflashed. It also provides for optimal fuel control and VTEC engagement control, which also allows you to keep your old key. It is possible to make corrections based on the throttle position, and the specifications for both low and high camshaft lobes are included. This is what is required in order to modify the VTEC engagement points without causing damage to the engine. Other options include a reflash (not an option in some areas and on certain Honda ECU's),or the aftermarket ECU route :- Bespoke Vtec controller, or Kpro can all help you set this up and get it working on an EX ecu. Notes about Civic Engine SwapsEngine swapping is a complicated process as not every engine can replace the stock one. This is why it is vital
to know the various swapping options that you have for your Honda Civic. Be Careful About The OBD SeriesWhile swapping an engine you also need to check for local laws as in many parts of the world you will only be allowed to swap engines with the same or newer OBD series.
Honda Civic 3rd Generation Swaps The Honda Civic 3rd generation was launched in 1984 and was offered until 1987. It came with the following engine options:
The most common swaps for the Honda Civic 3rd generation include:
Hasports is a trusted name that offers a wide array of components for the Honda Civic engine swaps and thus you can find the mounts from this manufacturer. Using the D series engines is a difficult process as fitting them isn’t a bolt-in process, unlike the B series. However, some car enthusiasts claim that the DOHC D16A fits easily due to its bolt-in nature. Honda Civic 4th Generation SwapsThe Honda Civic 4th generation came with the following engine options:
The B16A, B18A, and the ZC are the most commonly swapped engines for the 4th generation Honda Civic. Some other options include D16A8, D16A9, B16A2, B17A, and B16B . The swapping for D16A8, D16A9 and ZC is completely bolt-in which makes it a fairly easy process. However, the B16A, B18A, B16A2, B17A and B16B will require mounts from Place Racing or hasports. Another point to consider is that while swapping with the ZC, you might need to get a new hood or alter the existing one. Honda Civic 5th Generation SwapsThe 5th generation Honda Civic was offered with the following engine options:
The most common swaps for the Honda Civic 5th generation include: B16A2 and B16A3 can be easily swapped as it is a bolt-in process. The VTEC will have to be wired in this process and shift linkage from Hasports will be a must. B18B is also a bolt-in swap. However, the shift linkage from Hasports will also be needed for this swapping. B17A, B18C1, D16Z6 and D16Y8 are bolt-in swap options that will require wiring of the VTEC. B18C5 & B16B can be completely bolted in. However, this will necessitate OBD conversion and the VTEC will have to be wired. The H22A swapping won’t be as easy as the above-mentioned options. This is because it will require a mounting kit from hasports. Besides this, the VTEC will also have to be wired. We don’t recommend swapping the B16A as it involves too much work and the overall process is quite expensive. Honda Civic 6th Generation SwapsThe various engine options offered in the 6th generation of the Honda Civic include but are not limited to:
Here are the engine swap options for the 6th generation of the Honda Civic. B18C1, B16A2, B18C5, B16B, and D16Y8 can be completely swapped as bolt-ins. However, the VTEC requires wiring. Although swapping the B16A3 or the D16Z6 is fairly easy due to the bolt-in nature. However, besides wiring the VTEC, the OBD conversion is also required. The B18B1 is the easiest of the bunch to swap because of its bolt-in swapping nature with no other modifications required. The most difficult engine to swap for the Honda Civic 6th generation is the H22A which is not a bolt-in swapping process. Thus the use of shift linkage from hasports becomes a must. Besides this, the VTEC also requires wiring. Honda Civic 7th Generation SwapsThe Honda Civic 7th generation was offered with the following engine options:
The swapping options for this generation include: K20A2, which is an easy to swap complete bolt-in process. The shift linkage requires modifications; Honda Civic 8th generation SwapsThe 8th generation of the Honda Civic was offered with the following engine options:
Most people swap the R18 with the high-performance K series engines. However, this requires additional stuff such as mounts, wiring harness for the K series engine, dash harness, and aftermarket header. Some people also go for swapping the R18 with the B20 which has a bit more torque but the general performance of both engines is the same. That’s why swapping the R18 with the B20 is probably not a good option. Honda Civic 9th Generation SwapsThe Honda Civic 9th generation was offered with the following engine options:
There are forums full of people attempting to swap the K24 with the K20A. However, we don’t recommend that as it is more of a downgrade than an upgrade. A good option when it comes to swapping the engine of the 9th generation Honda Civic is the K20Z3. We have Civic tuning guides. A guide to Engines for your Civic Swaps.Any D Series (D16 - D17)A great choice, and probably one of the most popular Civic engine swap options out there, the VTEC is the engine of choice. The D series is a great bolt-in option, and give decent power, thanks to the high revving nature of the engines. With further mods you can take this further, but this starts to get costly, we see the D series as a straight swap option rather than a fit and tune up, although this is certainly possible. - Civic D16 ZCThe D16 ZCX which was never issued in America can easily be bought and found.
