Im thinking of heading down this path rather than getting a halfcut, as this would be cheaper for the time being.

As long as the time being is about 2 days, sure.

Subaru did not build their NA motors to cope with turbos. That is why they built turbo motors. You're welcome to try, but unless "low boost" is so low that it's not even doing anything it won't last long.

not so keen on 2.0L engines although there is nothing wrong with them, i want larger capacity so 2.5L will do the trick. expensive at that.

Whats wrong with the 2 litre engines? They go harder and make the same overall power. The JDM sti still uses the 2.0 litre. The ej207 has forged internals, while the ej257 has hypereutectic pistons, something to consider if you want to make big power. Plus an ej207 is cheaper.

The 257 makes more torque, and it makes it a lot earlier, making it a much more street friendly option.

I knew you wouldnt be happy. I was merely defending subaru's strongest and most proven engine From what I understand, the ej257 (41.5kg/m) makes less torque than the ej207 (43kg/m), it just makes more of it in the midrange. The ej257 isnt used in Japan, and many major competition racing sti cars still use the 207, so it is far from being an outdating engine.

Personally, I prefer the high revving and forged internals of ej207.

Each to their own.

Hmm okay, pros for both. Pretty much no cons.
As much as i want 2.5 it will be easier and cheaper to find say, ej207 halfcut.
Whats differences between ej205, ej 207 and ej208?
2.0L are just so tuneable, as are boxers in general.
I want mine to break 210kw with more left in the tank, achievable over time..

Ohh wow, thats handy to know. Thanks heaps!
Noticed you've got a 207 powered lib.. How many kw?
I reckon maybe i just flog engine n box out o mums 02 STi

haahahaa i wish!
if only it was that easyyy

A full 207 halfcut will cost you quite a bit - probably between 9 and 11 grand. It does include the whole motor and accessories, wiring, 6 speed (about 4k on its own) and at the very least front brembo brakes. Having said that if you have an ounce of mechanical sympathy you can back a 207 with a 5 speed just fine without destroying it.
The conversion is where the cost balloons. Everyone will tell you to go see Al at AM Auto but he's in Queensland, and what he does is not exactly rocket science. The hardest part of the job is splicing the wiring together (you need all the engine associated wiring merged in with your current interior wiring) but any auto sparky worth his salt should be able to do this.
Honestly, if you can do the motor swap yourself, and just send someone the wiring looms to splice (Al will do this for $600 or $800, I can't remember exactly) it's MUCH cheaper than having someone else do it for you, and really not difficult. I did it in a weekend with a few mates, although I borrowed a friends workshop and hoist to do it.

Other costs to consider - you will need a full exhaust, and no GC8 ones don't fit, although they can be modified to fit. You should definitely fit a new clutch to the gearbox while it's out. You should consider a full service (timing belts, water pump, as many gaskets as you can get at) because it's much easier to do on the floor than in the car. You'll also need EITHER a turbo bonnet or a FMIC.
Also put a few dollars aside for oils and fluids (motor and gearbox oil, coolant etc) and random bolts and things. Maybe even a sensor, as they can snap while you're shuffling things around.

far out, becoming more expensive than i originally thought
may aswell just buy an STi to begin with and mod it from there...

but i absolutely love my liberty and really dont wanna get rid of it.. but at the same time, needs a bit more power..

any decent mods i can do to it now while it's still NA, that may give me a few more kw? already got 2 and qtr inch mild steel catback..
if i cant get any more decent kw out of it, i'll just focus on suspension and brakes.

is it possible to remap the ecu and gain more torque and kw?

hmmm well now is the hard decision.. do i save up and buy an STi, or do i save up and convert mine.. i think the love for my car will make me want to keep it, and mod. dad wont agree but my money my car.
and if i convert i could make a 207 with minor mods blow a stock STi off the line.

i just dont wanna spend money on brakes and suspension if im not gonna keep it.
but i'll soon decide.

You might want to check out this thread mate, seems like a reasonable deal for the motor and all the wiring etc.
