just curious as to what a good upgrade engine for the rs4 3 evo would be. Any advice will help.

i put the o.s. .12 in my evo

For racing the OS .12 tz - very excellant, super reliable



For bashing the HPI .18 Nitro Star - absolutely direct drop in no mods



For hardcore bashing the OS .18 CVRX slide carb, side exhaust - unbeleiveable power, drops right in, only mod is seting up a slide carb linkage

Can I still use the Rotostart with those engine?

yes u can....unless its got a differnt back plate....which is hard to believe. I am not sure if .12's .15's and .18's share the same size plate. But it should all be the same.
