The biggest thing is getting everything ready for it. All rubber parts need to be changed, the ethanol dry's them up and if they are older and cracked well.. you get the picture. Anyways. Also you will need to double your injector size. You will also need a tune. If you have 90-94 injectors they will fail pretty much all the time. I know a good bit of honda guys have done this and made over 500whp on it. Is it worth it? To me. NO. I would stay stick with regular 93/91 gas. If you have a built motor and bigger turbo's vp c16 is your friend. :-)
