there should be no rush to decide what type of powerplant to use nor the final build weight. use the website as another resource. learn about all the different scenarios manufacturers and selfbuilds have entailed. they run the gamut from
sub 1000 lb bike engine to 1000lb 45 yr old 1 litre I4 Lotuses to 1200 lb 200hp demons to 1800 lb v8 beast and everything in between.
If ur prepared for multiple builds, then start as soon as u can, as u won't regret it. But if its a do it once, do it right, then tagging along for a year or so to see what transpires here, the locostusa list, the sevens list, meeting other owners and experiencing their se7ens will narrow down your focus.
GL!
