Aye the Jp4 sump is massive and weak as fuck too somehow. And electric throttles are gayyyy
Ryan_g86, the pistons are domed and dont have valve cutouts so your limited on how high lift the camshafts you fit are (J4 ones have cutouts and are supposedly stronger too although I cant verify that part myself). The rods are also thinner and weaker and arent fully floating like J4 ones are.
