Nope, youll be fine...all you need is a fuel pump for that setup, along with the FMU in the kit obviously.

Remember, if you go Hondata, you can still run the stock fuel pump. And its not a shot in the dark with reliability....if its done right on a motor thats in good shape, you'll be alright. You hear so many horror stories because so many people are idiots....improper installation for the most part, where they slap it on and go boosting everywhere until boom, they blow the motor usually due to inefficient fuel.
