At fixed budget and carrying capacity of trailer for spare wheels/tires, higher power may simply cause ending event much sooner due running out of tires, allowing to actually drift and actually learn less then if in more modest build.

86TOYO2k17: why staggered tire sizing? o_O
Sounds like inducing lot of understeer. And if anything, with quickly wearing tires out, i'd wish to get more out of limited count of spare wheels with tires i carried to event via rotating them to even out wear.
its hard to say what tire setup would be best really, its so dependent on power, weight distribution, suspension/alignment settings, personal preferences, driving style. with RWD and 350-400whp I don't think under steer would be an issue, but he wont know what he wants and needs in this regard until he has done the other mods.

I am not arguing with any of your advice you have given him thus far, it would normally be sound great advice. but i am not going to be his dad, life coach, or financial adviser. If he wants to blow all his money on a fully built perfect drift build for this platform then so be it.

Personally id buy something like a 2007-2010 rwd m3 for like $4K beat it to hell, and then put in a built block and tranny once it blows and some FI. But if he insists on a fully built perfect brz drift build so be it.

For that much sell your car and get something with more HP if thats what you want. IMO...upgrade tires at least the clutch/lightweight flywheel but, not to much would be my top three must do. Then catless headers, tune. Start taking shit off the car make it as light as you possibly can. Like 5lb battery mod, lightweight driveshaft, and yes lightweight pulleys thats up to you there is so much debate about them...So make up your own mind on that.

But its your car and money, I wanted to do FI but now after some of the mods I did I like the way the car is running and its pretty dang quick but still very good to daily drive or track. Oh and one thing I still want but haven't done is a good set of coilovers...

Based on the datalogging on Delicious Tuning's site, the boost increases with RPM. https://www.delicioustuning.com/doubled

Depending on the SC there may be a dedicated cooling circuit. If you're including hood vents, heat soak really shouldn't be a problem on either setup.
