A jdm accord b20a will bolt right up to your existing mounts not the usdm b20a5 found in the prelude!!! If your car is carbeurated you will have to convert to efi... if you want stay carb try looking for the jdm A18 twim carb engine!!! If your talking about the b20b/z you will need custom mounts for the b-series aslong as custom axels, shift linkage, and engine harness!!! We just did a group guy from innovative on 3geez.com... but its offically closed but try to log in and find the post maybe you can still get in!!!
