Forge turbo inlet would really compliment the intake, but it is a bit of a pain to find the correct silicone tube to fit the adapter to the takeda intake.
If youre considering motor mounts these are the best ones to get and i highly recommended getting both because it makes a serious difference and both together minimize the vibrations you'd otherwise get if you just got the lower mount, BUT if you do just get the lower, its still the BEST quality mount for the money in my personal opinion. Plus they ship it to you in like 2 days, their customer service is excellent.
Another common mod is a BOV or recirculating valve. I recommend GFB, as their valves are top notch. You can adjust the spring tension on the fly instead of having to swap springs and they have a dual port that lets you adjust either a full recirculating, full atmosphere, or any % combination of the 2.
The major mods people do are downpipes (HIGHLY recommend if you want more pops and burbles)
Intercoolers because these cars run a bit hot
And Full exhaust systems (none seem that good yet imo)
