The car CAN be turned just fine with an H22 in there. It's only 70 more pounds sitting in the front of your car. the engine sits a little different in the engine bay as well, but if you're really worried about the extra weight, you can get a CF hood and relocate the battery to the trunk, which offsets a good chunk of the weight gain.
Also, you don't need Prelude suspension components, just go with some good aftermarket shocks and springs.
