    You need to estimate how much power it'll make and then use an injector calculator to workout what size injectors you need.

    I use this one Fuel injector calculator, unfortunately it's only for petrol but to converter to e85 you would increase the required flow approx 35%

    Assuming 625hp at the crank on methanol, 1200cc should do the job.

    While we do sell injectors, we don't sell injectors of this size. We would recommend injectorsonline.com.au

    If you have any more questions please don't hesitate to ask.

    Kindest Regards,
    Steve
