"3342 which next should i upgrade?"

Drivetrain, for sure. Going to level 5 adds 3.2 km/h to total speed. (The other possible single upgrades would add 2.8, 1.9 and 1.6 km/h respectively.) It takes two i4s, though. Best chance to get them is buying Super Racer kit boxes twice or if possible thrice a day to fuse cards extensively but selectively. (To Nicks' advice, I'd also add that the first candidates for fusion are BPs for cars you're not interested in.)
