depends how much you want to spend aswell, the sc range are good turbo`s but they dont come cheap, the 18g does come cheap thats why i went for it, outspools the 20g and gives better midrange, should give 360-380, if you dont like it , i`m sure you would love it though, sell it and get something else
really dont know what would be best.im not going 6 speed so need to be a bit carefull with torque output,it dosent need to be a super quick spooler but certainly dont want a laggy turbo.
id like to see conciderable gains if im going to spend out,i would be happy with anything between 330-350lb ft,but would like 360+ in bhp really.
hmm decisions decisions, if a vf48 is on par with an 18g then would i not get similar results to what i have now?
does an sc42 deliver the power smoothly or will it **** my gearbox??

and has done for over 3 years on the dccd752 box,with over 30 drag runs and has never missed a beat,he also has launched the **** out of it,my car does not get treated this way.

OP has a Newage Sti engine in his, but yes I have seen 400+ from low mileage early STi engines too. I wouldn't however recommend anyone to tune an engine if they can't afford to replace it should all go wrong.

the motor i have now has scope for 450 ish but i do not want to break the box if i can help it,so looking for a little more power and torque now without a meth mix,just seems a very difficult decision to achieve the target without buying new£1500 turbo etc.(360/340)

If its expensive,yes is it,new one,if used you can pick up sometimes easily for good price.
18G should be OK,on yours or SC36 is great turbo which cost not too much as new

I know of 2 owners of STi 3/4 vehicles that put up to 540lbft through their standard boxes and they were still ok.
Other owners can destroy boxes with just 300bhp, so there is no safe limit, just wind it up and when it goes pop, rebuild it.

In my personal experience of the range of SC turbos, you may aswell go bigger roller bearing than smaller sleeve bearing, as they spool just as well as the little ones but make more power.

Sc36 can see 390 hp with a splash of meth
As you say that's pushing it though on you gear box
Although a mate has over 500 hp on sc42 on v5 but recently swapped out the 5 speed for a six ...
I've got a sc46 in blob and very impressed but want a sc36 in my sti v5 wagon as it's a everyday car and will get used for dogs, trips away etc

Yes, very smoothly and don't forget, the fact that it can produce 420bhp, doesn't mean it has to. Run a nice safe 380bhp if you prefer but it'll make no difference, if the box is going to go, it'll go regardless.
