20g on a new age wrx will be fine. I used to run one without a single incident for 5 years / 22k miles.
Mapped by JGM with various fuels, and in the end it spooled to 1 bar at around 3k in third gear onwards, full boost (1.5 bar) shortly afterwards (this with gt2 spec headers, which allegedly spool badly) on v-power only.

Right I have a 1995 fully forged 2.0 (pistons & rods etc), semi closed deck, with uprated oil pump, FMIC, and de-catted with Walbro, RCM lightened fly and Helix clutch.
I'll have top feed injectors, CDF racing top feed fuel rails (prob 550cc, currently have 440cc here), a tomei FPR, and will have wrapped tubular manifolds with up pipe.
I'm seriously considering a 20g to replace the 16g, would this be decent for my setup??
Would obviously be setup with an ESL and mapped properly, but I'm getting everything ready bit by bit.

550's like he said.
To the OP - I wouldn't even bother looking at a 20g unless you've gone for 6 speed gearbox and uprated internals - 400bhp in a WRX probably won't last that long - it'll likely do a few years before crapping itself unless it's high mileage already.
An old WRX engine I know of that used to run 400ish is still going in another car....just 3-4 years on, but it sounds shocking.
However I completely disagree with the comment that a 20g is unsuitable for a 2.0 - I run one on my STI and it's fine.
The boost and bhp/ft/lbs graphs show the 20g spools up about 300RPM later than the vf35 I had on the car before *but* that's also having gone to a FMIC so tbh there's very little difference IMHO.
Made 382bhp on a nearly dead clutch and OEM ported headers - suspect I'd see a little more if I put the GT Spec 2 headers I've bought on and Simon had another play with it as it's running a bit rich.
A good 20g should make close to 400bhp; uprated ones, or ones with tweaked housings etc should make 400+.
Am changing mine to an SC42 billet soon though in the search for just "a little more"

You'll potentially see 400bhp with the right mods.
If not, just add a splash of meth! I've heard SC38's make over 400 with meth no problem.
To illustrate, a mate runs an SC42 billet. Made about 425/390 with VPower, and 472bhp on a 20% meth mix!

Sti TMIC etc, K&N, 650cc injectors, fuel pump, decat uppipe, Prodrive sports cat, 2.5" system with resonator, WRX Sport back box, s/h AFP TD05-20G turbo, exedy pink H1 clutch.
Conservative remap by AFP - 360bhp 350 ft/lbs spool up starts at 3k revs, max boost 3k8 rpm. Unless you take it to 7k+ revs you go off full boost slightly, but I certainly enjoy it for overtaking..
