hi there, just looking for abit of info on these engines on the differences in them if there are any, mega zx21 ds4 EM, IDM evo 4, picco p7-r .21 evo 4 edo modified

I dont know the differences but the idm edo mod evo3 offroad with a 2013 just plain hauls and i get 10 minutes runtime on my d8t with hp8 bluethunder

I run a picco p7r-evo 3 edo mod, and it runs like crazy. The best way to go is with picco plugs, and 086 pipe the best combo.
