if you use 89 octane you´ll loose power, and that´s the beautiful thing about a b series engine its POWER! i only use 97 octane fuel on my sol and mine is an Si (SOCH VTEC d16z6 engine)
The manual recommends you use at least 91 octane (or something like that). I know for the del Sol Si, an octane level of 86 recommended, but I still use 91 octane.Densol said:I got a few questins. Beginner Qs I would say. Regarding playing with B16A2/3
