If your starting out from nothing then dont expect much left out of £10k, this is to do the engine+all ancillaries, brakes, suspension and gearbox all built by professionals. Obviously, cost can trimmed by buying used parts and doing certain items yourself.

same here i have got a sti9 ppp coming soon and would like more but have heard that the pistons are not good for over 350 bhp
so in your opinion what route would you go down
would like 390 bhp ish and about the same torque
so how much money have i got to save ????

Id recommend not bothering....sounds odd i know, BUT, have you driven say a 350bhp car? if not, and knowing roughly what your car is, then you would be surprised at how different they are to yours.
Id recommend getting the most out of your 2.0 first with say....a VF34 and the pinks and an STI cooler.....the difference will be night and day just from that.
If down the line you fancy more? then think about it.
Dont make the jump from say...260 to 500...youll kill yourself.

I have watched Neils car from the start and learned a good 2.5 isn't as simple as sticking a 2.5 bottom end in
as no one has mentioned costs
PowerStation
so thats 10 k gone
Zen Performance - Drivetrain
now theres another 3k gone
now I can't find a 321T on the web but probably looking £1200 - £1400 ish
im guessing you will be wanting a fmic to go with that so lets say £1000 for a APS one
so there's your first £15,000 gone
, and we are still using a closed deck block now it can be done cheaper and this is the expensive end of the scale
but gives you some idea how easy these things start costing allot of money,
it would be nice for Mark to add more on costs as i am currenty in the position to be moving to to a built engine and these costs are scaring me in to sticking with the 2 litre
or he could finish his web site

TBH those where the kind of figures i had thought of, but that is to be spent over the course of the year

STi intercooler is much more efficient 
less pressure drop and better charge cooling.
No actual difference in "driving" but allows mappers to dial in more boost and advance over the WRX item

Would there be much benefit gained by replacing the intercooler on my 01 WRX at the same time as getting an Andy F TD04 Hybrid turbo ? The car's running 273 bhp at the mo, was looking at getting to 320bhp.

it just confuses matters, now if you meant an MY06 UK STi and not an MY06 STi 12 (as it would be known if the numbering continued as the uk never had STi's until 2002 so you would need to get upto 2011 to be upto an STi 9) then yes the pistons are not very strong, though the pistons on a JDM of the same year but in the 2ltr block are considerably stronger than those in the 2.5ltr Tony

I am not sure having a JDM starting block is of any benefit to the EDM 2.5 block at all.....FSTi is a bit of a one off....

ok easy one. got to Scooby Clinic | The UK's Largest Independent Subaru Specialists hit the sc450, add gearbox and clutch hey presto reliable 450bhp/480ftlb in a ready made package , and your sorted for running gear as well.
The gaffer has been running the development engine for the past 12 months with no probs except killing rear tyres (its in a 22b) lol

pmsl, tios an awesome engine, custom turbo that iirc had to go back 7 times tio get the right balance between power and as little lag as possible. doubt you'll do better tbh, getting that kinda power isn't that hard, but getting it reliably is another story

450/480:)
I have an 03 STi and want to do something similar 450/480 approx, what would I need on that to produce the figures
MD321t ?
2.5 bottom end
Injectors ?
FMIC? (which one)
Wiseco pistons ?
Eagle con rods ?
My car has full blitz decat,standard ported headers,APS CAIK.
Hopefully things may have moved on from the last post on this thread so up we go.

Is worth spending a bit extra on Cosworth/carillo rods
You will need to add GT spec headers & up-pipe, Ecutec remap, fuel pump (intank bosch 044 for reliability)

cant wait to get it back 
i only needed block and heads etc etc already got most parts fitted, but the package will set you back aprox £12,000+vat including straight cut PPG, so drive in with 280BHP and then drive out with 450bhp/480ftlb you get the neck brace for free

is that using all new or some second hand parts?
i looked into it about 6 onths ago and no one could get near price wise, and i must have rung about 8 companys including all the big names you can think of

Dont' get suckered in to thinking a "proper" build is just about the engine, turbo and ECU mapping. A lot more goes in to this type of build (ancillary wise), especially if you are going to use it on track etc.
