You can get 1800A 2100V IGBT's if you have the wallet. I have not seen 1800A IGBTs under 600V rated.

I would spend some of that cash on a high-throughput glycol-cooled heat sink so you don't melt anything.

AC35 or AC50 on each wheel would be fun. Finding and sourcing a gearbox that will drop the RPM available to match your desired top speed is likely where you will find difficulty. If you do find a single-speed gearbox that works for you, it may not fit into the space that is available.

I think that's why most conversions use the FWD manual transaxle, or a drive shaft to a standard rear differential ... but that's only a guess.
