Plug in and play 
obviously to get the most with any mod though a remap would be needed at some point.
The TD05 is slightly more laggy at bottom end hence why I decatted mine.
Boosts hard all the way to red line!

What year is it? MY99/00 really don't like those mushrooms.
Anyway, my choice for a UK car would be
VF35
FMIC
bigger injectors if need be
Fettled exhaust manifold
Uprated fuel pump and regulator
And ECU of your choice, TEK, PFC or Simtek
Should see you well into 300hp

I don't think you really need a FMIC unless you are going for over 400bhp IMO creates too much unneeded lag.
My choice would be:
TD05
STI 8 TMIC & scoop
decat pipe
Z5 ECU (8k rev limit
)
Modded air box with panel filter.

scoobynet myth machine strikes again,,, lol
if mapped correctly you wont get lag from a front mount, also benefits are seen from as low as 300.
there was a whole thread a while back about it

FPR shouldn't be needed
walbrough 255 - few different ones but thats easily available and not too expensive.
440 injectors will be ok for hte that level of tune, but if you plan to go more later then 550's would give you head room, however to go above the level of 440's your gonna need to consider other things, like gearbox and forged build

TD05-16g is a great turbo.
Will need a remap and a STi8 TMIC will do the job very nicely.
Limit your power aspirations if money is an issue as a TD05-16g is more than capable of killing your gearbox (budget £2000-3000k for stronger boxes). Even at low boost (1-1.2 bar) the TD05 is quick.

My 2 litre spec was:
VF28
Lateral headers
Fully de-catted
Apexi PFC
simota panel filter
it made 320bhp/300lbft of torque.
I'd recommend the VF28, not much lag & made for a very swift car, streets apart from the TD04. i'm still running it on my 2.5 & it performs very nicely, much like the TD04 did on a 2 litre.
I certainly wouldn't just bolt on a bigger turbo without getting a remap, you are asking for trouble in my opinion. Depending on whether you have the phase 1.5 or Phase 2 engine & management will determine whether or not you need an aftermarket ECU like the Apexi PFC. The 1998 ECU's aren't currently mappable I believe.
I reckon a VF28/34/35 with a set of ported headers & a remap will totally transform your car.

Theres arguments for and against FMICs but its still in the wrong place on top of the engine. I also stand by VF35 over TD05 - AFAIK the VF will be on song first and be a much better road car turbo. You want it useable not at a point where by the time the turbo is upand running its time for another corner
As its a 98, you can't have TEK mapping so a Power FC would be your first port of call

Connor, I personally wouldn't just stick another turbo on it and give it the beans. Your boost will be all over the place.
Pm 'Dunx' on here. Hes got a Bugeye STi and wacked a great big turbo on it in place of his VF34. It showed peak boost on his Defi's @ 2.0bar
before JGM mapped it again. That worked out at 525bhp he reckoned, which could have blown his engine. He's now running a safe 390bhp with the same set up.
If you can't afford the map, don't buy the turbo imo Or just expect trouble. Also, standard topmount will be ok for 300bhp, although a STi upgrade would help more. No need for a FMIC again imo for that power, unless you plan on consistantly running 3 figures when the romours about the bonnet scoop come into play

Bin the mushroom filter, crap
get a decat downpipe, good
go back to standard leads as all other fall short in comparison
check injectors aren't still 380s if so go 440
ignore the 16g haters, its one of the best you can buy, early IHI are cholcolate by comparison
get a walbro pump and SX regulator, avoid FSE like herpes
and FFS get some better brakes BEFORE you put the power up

and suspension. Didn't hike the power in my old Scoob, but the brakes were good and the suspension was overhauled so a better drive all round.
