Default Suggestions for next place to send money on power.

Hey guys. I have a 2004 WRX, 142k, clean and healthy.

It has:

VF48
STi injectors
STi tmic
Tomei UEL headers w/ 3-bolt up pipe
Invidia Bellmouth down pipe.
K'Sai full 3" exhaust.

I'm looking for a little bit more power.

I've thought about injectors and a bigger pump and having it tuned to e85, but I'm not hell bent on that.

I've considered a 16g or 18g with a billet wheel, but I'd still need injectors and a bigger pump.

Is there anything I can do to get any more out of the Vf48, other than e85 or Meth or a new bottom end?

A lightweight pulley you do not have.
A lightweight steel driveshaft you do not have.
TGV deletes you do not have.
Your tuner can let you know if an intake may help at this stage.
You can get smaller wheels/tires to improve acceleration and reduce driveline shock.
You should not look so much at the billet wheel as the BB center cartridge of new turbos for inspiration....16G XTR is nice and I have been running unit #1 since they were invented 3-4 years ago.

There's other idears but we don't know your budget or car's use.

My budget is that if its a logical purchase, that will increase performance, Ill look into it.

I daily drive my car but run a lot of mountain roads, and spirited daily driving. I like my 18x8's, but i definitely have thought about some lighter wheels.

TGV's are on my list when Do the turbo inlet, as Ill just take the manifold off this time.

I was thinking to stock pile these parts:

I was actually looking at the 16g XTR but probably a 16g of some sort, Ball bearing.
TGV Deletes - Composite or nah?
Turbo Inlet - Probably a hard inlet this time
1000cc or somewhere near there injectors
Walbro Fuel Pump
Cobb 3-port
New Tune.

Lightweight pulley adversely affect anything?
Weight difference in a lighweight drive shaft vs stock?
