Powerstation do a 400+ package on the JDM new age (twin scroll model cars) for 2.5k 
If its one of Iains cars with the miltek exhaust then you wont have any problems, will run pretty much 400bhp with the turbo upgrade, upgraded injectors and a couple of other minor bits.
Also not known one JDM Twin scroll engine to let go, they are very strong considering they dont have those dodgy cast pistons

If I recall correctly several tuners have exceeded the 400bhp mark without opening the bottom end up. Indeed Scoobymania were running nigh on 500bhp on the standard bottom end without any problems. A Greek based tuning company got 475bhp on the standard bottom end with the original top mount intercooler! Although they had extensive fuelling and cooling mods.

Infact forget the 400bhp figure, optimise things on an STI and without changing anything major like the turbo you will get fairly close and save a lot of money. The drive will be great and then in due course if you want to go further the option will be there.

Serious question though David
How many twin scroll turbo engines have you seen with broken/melted pistons compared to the uk/jdm forged ones
Truth is, those hypereuetic pistons seem to be able to take boost very well (the 2ltr engines not the 2.5 which are weak) and are meant to be stronger than the forged pistons due to the alloy and casting process.
Your input would be appreciated

Once you have done the stage one mods and decide after that you still yearn for power then go for it. Initially I would keep my money firmly in my pocket. Listen to Staffi he talks sense.

Tony,
Thats not exactly true now is it, regarding the PS Stage 4 price you have quoted. The price you have quoted is assuming it is already at a certain level beforehand. So not really fair highlighting that against what API has quoted.
Make no mistake...... power and reliability costs money!!! I could buy another Spec C for what the latest round of mods on my car cost.
True... the JDM's (same as anything else as David has pointed out) seem strong. Mine hasnt missed a beat in 2yrs and see's loads more action than a high % of owners cars...... but as David says, not much information exists as benchmarks so its all subjective really.
Shaun.

I'm curious about this, having only had a 10 minute shot in an Evo 8 to date. In what way do people find the impreza a more satisfying drive ?

Andy, i wouldn`t say in my experience having had a Mak that Subaru is more satisfying to drive, i just think it has a little more character, the exhaust note for one, but all this is just my opinion, evos are awesome cars...

The character element for one (admittedly subjective). The interior is better in the Impreza (unbelievably), I found the Evo a tad hard, harsh even so at slow town speeds the Impreza again came trumps. Little things like the clutch action and gearchange I prefer in the Impreza.

TBH, it`s going to take some Subaru to impress you with the power you`ve got in the evo
unless you go out in Zens.. What exactly are you looking for?? i knew when i bought mine it was going to loose out on the Mak after 120 or so and it`s pretty hardcore being an RA, but i wanted something that would give me a buzz at the weekends and this certainly does...
when it`s not at API having work done that is..

For a new age euro STI:
Sports cat 3" exhaust
650cc injectors
MD321h turbo
Walbro fuel pump
Hyperflow cold air induction kit
Ecutek remap
£4200 inc vat fitted.
390hp at 1.45bar with those exact mods, on a UK STI 7, standard headers, standard TMIC, standard engine. The same build of bottom end has done over 40,000 miles at around 400hp in another car.

sorry to throw this in, some of us are just lucky I Guess
Bearing in mind the car did already have APS DR725 FMIC, & 3" sports cat exhaust, I managed to get it up to 420 bhp & 385lb/ft for £2600,
Perrin Rotated mount turbo kit £1500 (comes with everything you need including Garrett GT 30) needed some special mods which I done myself at no cost to fit)
650cc Sards £250
Headers £250
Remap £400
Equal fuel rails £200
