I was planning on swapping a H22 in a 93 Honda civic HB.
But some people say the engine is too heavy for the front
Suspension. Do you think it is possible to drop a Prelude
Suspension in the front so it could take the weight of the
Engine.

the h22 is only 75 lbs. heavier than a b series engine, so w/ a nice suspension set up you won't even know its in there ( until you hit the gas ), my friend has an h22 hatch ( 93 ) and that thing fucking rips hard. do it man, you won't regret it. he has ground controls w/ a custom spring rate and kyb agx's, he also has a lot of other suspension mods, like and itr strut bar, rear sway bar, lower tie bar, 6 point roll cage, and a few other things too. and benin industries ( suspension experts ) are making him some custom bar ( can't remember the name of it ) to put in his car and let them know how it works before they start selling it, but neways i would def do it if i was all about going really fast. by the way he has hcp mounts and they work really well, but i would suggest getting the hasport mounts, i have some experience w/ hasport and there shit is def top of the line.
