Different Types of H22a Engines:
So you are swapping to a H22a Engine and looking for the correct parts, upgrades and more items to increase your out of engine time. Maybe even thought about the h23 bottom end
The 2 types of H22 swaps are the h22a OBD 1 and the h22a OBD 2. Some people go for the Type-S engine swap but you don't really get that much more performance but it sounds more impressive on the car's resume
Most of the swaps are being done into the Honda Civic and the Honda Accord. Both of the hybrid modifications will take some changes but more so for the Civic then Accord as it is known to be a "drop in". The Civic typically needs a list of parts to make the swap work out like Axles, Shift linkage, Engine mounts and wiring harness conversion. Of course you will have to decide if you want to keep things like power steering and air conditioning... some of the more race oriented people drop those ammenities for overall power. Most tuners recommend before installing your engine is to do a basic tune up and maybe even replace air valves, fuel filters and hoses. Spending some time reading forums and walk throughs will help with your h22a engine swap as you are likely to learn some tips and tricks on this project.
