Research your engines buddy. The prelude motor will fit. They make mounts for them
www.hasport.com . NO you will not have to even out the weight by putting something in your trunk. Stiffen up your front shocks/springs and you won't be able to tell you have a heavier motor in there. They don't weigh that much more and you can take curves easily. Just change your ECU for the vtec "complications". I know my Hondas.
