I have a friend that raced an h22a against a Thunderbird with a V8 in it,even for a 4 cylinder it kept up with the v8. Check out our guide for more details. Either way the head needs to pulled and repaired. I understand completely what you are saying now. It'll make the engine even more off balance than it was and it'll destroy itself with normal usage. What about the new K-series motors? This goes as well for the Integra Type R head. You could leave it as is and simply swap the head for B16 model.
The A1 is the pre-obd engine that came with a cable transmission and various other pre 5th gen. This causes all types of havoc with your other systems, including suspension, braking and cooling. It is a small displacement engine that has flat torque line!!! This is normally not too bad because things are very well lubricated in your engine. Because from what I've heard, both engines can make ungodly power. If you have the money and like spending it on high octane gas for your 4 banger, why not? This does considerably reduce the maximum possible power output from these engines.
The engine is also of course very large in size so it's a tight fit into the tiny civic engine bay providing that you make space by removing both air-conditioning and power steering systems. The reason I point this out is because all 5th and 6th gen. Honda part numbers would be greatly appreciated. But if you don't plan on turbocharging this engine past 15 psi or letting it rev to 11,000 rpm, then it should meet your modest power needs. Throttle bracket and cable differences can often mess things up for you at this stage.
This needs to be done right or you're left with an engine that leaks oil, has Vtec engagement problems and possibly valves that smash into pistons. Although a turbocharger can be bolted on to this bad-boy, it's generally not recommended, as this is a very high compression engine. The lack of which could result in damage from prolonged high-rpm usage. Once it stops, get out and check your fuel injectors and your fuel pressure : Let us know how it turns out! This is the most desired swap candidate. This needs to be done right or you're left with an engine that leaks oil, has Vtec engagement problems and possibly valves that smash into pistons.
These are extremely easy to find since allot ppl swap them out in favor for more expensive engines. In reality, the majority of your engines power capabilities come from head design. First off I need to mention a few things. These subtleties can greatly affect the overall power production of your new engine design. I really need to go to school for this stuff.
H22 Civic Swap Guide F20B: This 2. Swapping from your 2000 Accord F23 into your 1993 Accord can be done, but this will require custom motor mounts to get things lined up properly. The 2 bolt bracket will not line up properly if the front of the engine is sucked in toward your frame rail or towards the driver side more than the passenger side. He beat me at take off, beat me for like 9 seconds. This will allow you to get the car started.
It's all math is what it is. If we spoonfeed you everything, you likely will not end up getting what you want. Honda part numbers would be greatly appreciated. This does considerably reduce the maximum possible power output from these engines. Instead ditch it and go with a manual transmission. Which crankshaft would work best in this set up, I have all 3 b16, b18, and b20 connecting rods. .
Valve clearance is another issue that needs to be addressed before you not only mate the head and block but also play with cam timing. As with the B16 if you opt for the 1990-1993 Integra axles you will need a change at the intermediate shaft. Block surface and the bottom of the head are totally different. Both of which are very important when revving to 9000 rpm. It involves placing a few hundred pounds of weight in the trunk to even out the weight distribution. All of which will have their pros and cons. If you have the extra money, you could swap in an all aluminum thick ass racing radiator with a smaller and more efficient fan and for extra insurance, a low temperature thermostat 160 degree rather than 180 could be replaced.
