Anything at 1000whp is going to need the same upgrades with stronger rods and likely pistons (even though the stock pistons have proven themselves pretty stout so far at the 900+whp level on Mr Vanos’ M5 I believe). Big item to go beyond that is solving the fueling issue which we are accomplishing with addition of port injection and new in tank pump setup to support e85. Other option is to go with modified cams and upgraded HPFP’s (spool is supposed to offer something soon), but even with this, you may hit limit on what direct injection fuel injectors can flow. I am not a fan of add on meth injection but that definitely can help with shortage of fueling too.
