Been running approx 340/330 in my MY99 Uk turbo with the standard box and it still seems spot on after 6 months of (fairly hard but careful) use!
Just get it serviced every 3000 and let it warm and cool properly.
Above std spec I've got:
Apexi Power intake induction kit in heat reduction chamber.
Hybrid GT Spec FMIC.
TD05 16g turbo with porting.
Ported exhaust headers.
Full decat with TSL group N backbox.
Three port boost solenoid.
Walbro 255lph fuel pump.
A'pexi Power FC ECU and Commander (mapped by Pat Herborn for V-Power).

Assuming you have supporting mods and are having it mapped, without I would think fitting a TD05 might make the car feel worse, with later spool up and little increase in power, although I may be corrected!

Sorry for the late reply. So far ive got a TSL panel filter, sports cat downpipe, uprated fuel pump and a full hayward and scott system. All of which has been remapped by simon aka JGM on the standard td04 turbo. Have spoken to simon about what i want to do next and he has given it the thumbs up.
Regards Dan.

you will see some, but if its a 99/2000 car thena vf35 or 34 would be the better option

Mine ran as flat as a pancake with the VF35 fitted on the way to the remap.
To add to what that person said, there is also significant risk of engine damage fitting a larger turbo without a remap as the car is flowing a lot more air and needs the fueling to match!

i was running 390/352 with obviously the supporting mods...went through 5 gearboxes 
but if u want ur box to last in my opinion u shud not go over 320bhp....but its torque that eats the box away really.

2 things to say on this thread....
IMO you can not just say a car can take ***bhp
1. The thing is every car is different, yours may have piston slap or hi noc levels that someone else dose not and so when mapping the mapper may have to say at some point it would really not be safe to take the power any higher.
2. Gearbox Gearbox Gearbox!!! Trust me I know all about these things! IV had the one that came with the car blow, a rebuilt uk box by api blow and a rebuilt RA box blow and that has been in the last 4 months!!!!
Just got myself a Uk STi 6 speed and it is lovely! Really close gears and strong as an ox!
Should all so say all these boxes went with me running a TD04 hybrid and about 320bhp so be ready to get your money out for a new box at the level your looking to go for!
2k should do it and some one to fit it on top!

i see i am not the only one in this position.
only just got my car running right last week a 99 uk turbo, with a lot of phone calls, emails, visits with the guys a subaru4you and Bob R. finaly sorted and wow what a pleasure to drive.
running a 2004 uk WRX lump
VF28 (From a P1 came up at a good price would of liked a 18g really)
Hybrid FMIC
550 Injectors
Full decat system
Fuel Lab Pressure Reg
Walbro Fuel Pump
K &N Induction Kit
Uprated headers and Up-pipe
Apexi PFC
AVC-R
Running 318bhp-303Lb
so i am very happy but already want to get more power, as at the time when i got it, i had a major fueling problem, and making no mid range power, been a slow process but just wish i had some more cash at the time and i would of gone for a bigger turbo like a 18g-20g as the engine should of been ok to hold up, but it was the cost for the bigger turbo and the gearbox that i did not have so had to settle for less as it needed to be done asap as it is my daily driver.
but now my cash short fall is getting better i really want to go for a 6 speed but not to sure if it worth throwing more cash at a uk car might sell up and get a type r, but saying that if i change the box, and up the psec of the engine or even go for a 2.5 lump there is no real point doing it ti a sti as i will be replacing most if not all sti parts anyway

Good little read this! I we shouldnt really under estimate our UK cars 
I suppose the gearbox is an area for concern on all the classics, even with classic Sti`s when runnnig big torque figures through them.

the question i am stuck with is
are the uk cars that much off a sti when you start going down the modding road.
surley when doing a 400+ bhp project by the time you replace the gearbox with a 6 speed, the engine with uprated internals (which you would do on a sti) or swap for a 2.5ltr, obvious a brake and suspension upgrade (which again is usaly done on a sti) what has a sti as a base car got over a uk car other than different seats, rear lights, lighter bonnet and bootlid or am i missing something as if there is nothng i will take my uk car up to the next level if not i will sell up and start again on a sti or newage
can anyone give me the answer
the end result is the same.

not sure what power my wagon is running but its 20psi on one of Andy F's 18g's...HKS fmic, 550's, fuellabs regulator, etc supporting mods so I'd imagine its a fair bit over 360. Since September last year, only issues so far are tyre and fuel consumption
I'm running a P1 box and diff after breaking two MY00 boxes at sub 300; broke 4th on the first one and stripped 2nd on the next.
imo I don't think its worth pushing more than 340\350 unless you are prepared to shell out for a rebuild.

i know th e p1 box is ment to be the stronger of the 5 speed boxes but as you say think it will more than likely be on its limit and i guess as the millage racks up the less reliable it may become

on andy forrest web page he seems to think that on std engine internals the 99-00 uk lump can do 360bhp-390bhp a similar for a 01-05 uk wrx lump which is stage 3 (but to address the clutch and box) then stage 4-5 is suggested to up rate the internals.

UK cars ended up with a smaller turbo (TD04) which will get you to approx 270bhp untill it starts running out of puff. Interior/exterior obviously not as appealing as an Sti but really its not that much of a major difference in comfort.
You could probably sell and go for an STi, but you`ve probably already realised that once you do get to over 300 torque your getting ready for a new gear box, and thats with both UK and STi cars.
I was stuck in dilemma about selling and getting an STi type R, not for the engine side of it, but cause I like the 2 door look. Had a good think and stuck with my UK.
Swings and roundabouts mate, either way you still end up spending the same amount of money, itl just go in different areas of the car depending on what you got IMO.
I say keep your UK car mate cos its your base for mods, if you sell it you might end up missing it.
