with the 90+ accord, it will be easier to swap in the H22A with few issues (it's pretty much a direct replacement for the F22A). It can be done on the prelude, but you need the mount kit (place racing has them as stated above) and there's alot less room under the hood of the prelude, so you may need to sacrifice A/C and/or Power steering (I'm sure they can modified to work but it's work/$$$). The prelude is a great car, but it just wasn't built with the newer motors in mind.
