If your serious about chasing power but not too attached to your car,
Would be cheaper to sell up and buy one at the power you want,
To take to 450bhp from pretty much stock will be a fair amount of cash
Be cheaper to get a fuel pump, pressure reg & a decent 20gTD05 cross fingers and pray for 400 before u max injectors.

Stock tmic and airbox should be good for 420
All depends how much you push the car,most go fmic above 400 due to heat soak.
Performance exhaust manifold will aid spool but a stock set up shouldn't be a limiting factor.
Best advice would be speak to your mapper.

Have a word with Martyn J at engine tuner regarding mamba,he'll also advise better on what you need to hit your target 
Remember tho it's not always about the headline figure but more about drivability.

I’ve also had so many new turbo brands advice I’m a little bit baffled.and your all giving me what works for your Subaru STI thanks
but how will I know which is best for mine
I want the best sprool no lag to take me from my stock 350 bhp to 400 + maybe bhp
So many to choose from is bearing better is a certain brand better and obviously don’t ealwant to take it to the levels where I will mess the engine up so
a nice so it won’t make me to forge the engine and clutch and gear box a what else that’s costly
dont want the expense and head ache
need that response when I hit the throttle
sorry guys being to much with what I want maybe can’t have it all hey
thanks again 👍

Your modifying your car to push a fair bit from standard,in fact you already are at 350 so you always run the risk of problems,your car is also 14 years old
If you don't want to take any risk then keep it standard.
Oh and choose a decent tuner to give you a better chance of not blowing your engine up.
People and comments above are correct....Big Money to run safe and big power,,forged engine 5k+ for peace of mind.

I'm running an sc42 twin scroll at 1.65bar boost on an old UK spec bottom end(my95 I think),do I expect it to last,hell no!
The short block I'm running rolled out of the factory with 215bhp and I've got to be pushing 400,I'm still shocked that it's lasted 12k miles and still sounds sweet as

I'm going to stick my neck out here and say:
A standard Newage STI can be taken to 400> bhp for sub £2.5K based on second hand cars and the current engine etc being sound. I know, because I have done it several times!!
Turbo £750
Inlet £50
Exhaust £200
Injectors or FPR £200
CAI (not essential) £150
TMIC will do 400bhp, or FMIC £500
Fuel Pump £100
Remap £400
where am I at.... £2350 ? of which some is not required...
Only thing missing is Garage time unless you are doing it all yourself?

As well as all the other very expensive, non-essential stuff for 400bhp that folk get hung up on.

If your base car for mods is as you have mentioned a Newage STI then 400+bhp is easily obtainable but...you will have to throw a couple of choice modifications on it.I answered you on your other thread...Rob Day is about right price wise if you buy used parts,on the other hand if you buy Gucci modifications you can add another couple of grand to the price that Rob Day mentioned, you don't need to forge for 400bhp as the STI engine is quite robust as i was running 450bhp for 5 years before the engine got replaced in to my wife's Subaru classic and its still running fine,Syvecs would be a nice engine management upgrade but it can be acheived on Ecutek software now with the right mapper but with less functions.You have to set yourself a realistic budget that you can comfortably afford and work from there,sometimes asking one question can get you a thousand and one answers..and not all of them correct!...if you get my drift

''Coil overs on the front, stock suspension on the rear''
That sounds like an unusual set up... that could provide some interesting handling characteristics
