you will need , oil cooler, lots of tires, suspension and a decent cat back zorst and filter , and good pads / disc combo to start .. a remapped ecu wont hurt , and then you can add cams .. bar that they are pretty bomb proof , i've done lots in my vr6 turbo.. so im well versed to no what fails. gearboxes will be fine at your power level, unless its very unhealthly
