basically all of the turbo kits out there for your prelude will be the same as on the stock h22, prolly be a lot cheaper and have a lot less r&d than building one yourself, the only physical difference i would think between the f20 and the h22 would be the height of the block, which might mean you need a slightly shorter intercooler piping
