will a 91 crx si motor bolt into a 1986 CRX hf. its a d16 i believe. Are the mounts different for the EW1 or whatever is in there right now. I am just contemplating this. If anybody can tell me why i should or should not do this please do. I am good with wiring and custom fab work, so that alone will not scare me out of this swap, but money will. If it will be costly i will deal with the 58 horsies i have now. Thanks.
