if your serious about doing this id go with a propane conversion they are cheaper than cng mostly because you dont need to buy a $1500-$3000 cng tank. also some are even bi-fuel so you can switch from propane to gas while driving down the road. although i dont think they make them for fuel injected engines only carbs. do a google search on "impco" should give you more info
