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. 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. 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.
Many 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.
For example, the LX and DX blocks are identical with the exception of the compression ratios, which are 9. If you intend to turbocharge , a lower compression ratio will be advantageous.
Getting an EX ecu with an EX engine harness is one of your wiring possibilities when completing a change like this. 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. 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. Honda b17a1 which came in the db2 platform gsr Integra and was the first B Series Motor to be marketed in North America and a lot of people may not know this but it also came with the ys-1 cable tranny which was different than every other B Series Motor because it was fitted with a different input shaft and a shorter final drive ratio!

First, its important to decide what you're goals are. If you're interested in running 15 second quarter miles without hassle or complication then finding a B16 is probably your best bet. Some of us are interested in running 11 and 12 second quarter miles.
For this type of performance it's important to plan every detail so that the engine is capable and reliable when asked to perform. Another part of planning that should be done before the swap begins is whether or the engine will be naturally aspirated or have forced induction.
These are all questions that need to be answered before the swap so that you're satisfied when everything is complete. Many of these engine sets are left out, exposed to the elements for long periods of time.
Most important thing to remember however is to remain realistic. There are many people who get grandiose dreams and set high expectations for the Honda engine swap.
This is another area where the wonderful world of Honda interchangeability can make things more difficult than they need to be. Check out our primer here to figure out which engine computer you need to properly complete your Honda engine swap or to wire in VTEC.
So you decided to do the wiring in your Honda swap yourself. In some vehicles or Hondas this collection occurs on the firewall, or at several sub harnesses along the shock tower or glovebox. If the vehicle your swapping into is available in a higher trim that happens to have the engineer swapping in, forget about a donor harness. For example, if you are swapping in a B16 to a Honda DX, save some money simply add the wiring you need.
Further, if you purchase a JDM engine the harness will lead the wrong way because those vehicles are right hand drive. Secondly you want to inspect all the connectors to make sure that none are chopped up or damaged.
Very rarely does any Honda swap bolt right in without some small amount of electrical modification. Of course one of the main reasons to wire up your engine swap will be to add VTEC.
