I am looking at building a engine to suit 300+kw. I would like to know where I should start at. I am budgeting somehere in between 20-30k for a new built engine, sti goodies like brakes, box diffs and so on.
I was considering a bit of track work but that can always come later if I decide. Now I would like a nice street car that is pretty much bulletproof.
Any feed back is welcome and will help with what direction I want to go with the car.

cheers

20K would be a 'start' if you're doing things properly.

Your first decision should be "who is going to do the work?"

If you choose a workshop in Perth you trust, then choose the ECU and motor package that they recommend. A list of some of the workshops in Perth that work on Subaru's can be found here:
http://www.perth-wrx.com/vb/mechanicals/6775-perth-workshops.html

If you choose to do the work yourself, good luck! Another thing to consider is that using engine parts, turbos, ECU's etc that your chosen tuner doesn't like can lead to issues like them not wanting to tune your car, not being as aggressive with the tune leading to less horsepower. But thats up to each tuner.

Have you got lots of money? you'll need it. Building an engine seems cheap when you look at the price of parts individualy, but start adding them up, import duty, GST, labour, genuine gaskets and fluids etc and you can be in for a big suprise. Genuine good quality parts are expensive, China knock offs are cheap. The last thing you want to do is spend dozens of thousands on a motor, not have enough money left over and buy some shitty china turbo that fails and takes a motor with it. One saying you'll get used to is "oh well, while i'm here I may as well ..." Got the heads off for the engine build? "i guess I may as well get cams" oh well, the cams are out, "i guess i may as well get spings and valves" etc etc. things you never wanted and never budgeted for will come out of the woodwork and empty your wallet


Some places i'd look:

All Star Garage are a Cosworth dealer in Australia and the owners have some seriously quick WRX's, they have done a few hi-po builds including:

Wai - http://www.perth-wrx.com/vb/general-subaru-discussion/12954-project-%5Bgive-wai%5D.html

Cypher Industries have the quickest under 2L car (FWD Civic) running around wanneroo at the moment

Mattmy99 - http://www.perth-wrx.com/vb/mechanicals/22580-mattmy99s-hatch-build-thread.html

Maximum Motorsport are a local Rally shop behind Dean Herridge, have been in the industry for ages.

That's not an exhaustive list of places in WA that can do your work but it should help you start.

Now that you have chosen a workshop to do the work, choose what you want: Fast street car, drag strip cars, long track car (wanneroo, collie), short course (point to point motorkhana, hill climb) etc. A lot of people come on here saying "i want to build my car to occasionaly race it" and talk it up, but never go anywhere near a track, not even to watch. Are you one of them? Do you want a drag car that has sloppy suspension so it squats off the line and runs a 10? do you want a heap lag and a heap of horsepower and some handling so you can rocket down the main straight at Wanneroo? do you want to be able to blaze the rear tyres around an MC course? these decisions will help mould what mods will work for you.

How reliable do you want your "weekend car" to be? is it always going to be off the road with a snapped shaft or a busted turbo seal? will this shit you to tears?

The old saying comes into play and is so god damn true its irritatingly funny: You can have a car thats cheap, fast and reliable - choose two

Budget $20k for the build alone if you're going for a 2.6 - That's at 2008 prices and not including any other parts (turbo, injectors, ecu, tune, etc etc etc).

Why not go for less power and forget the build? Worry about it when your motor pops. For example, 250-270kW is still a descent whack of power for both road and track.

Have a look at Andrew's wrx as an example:
http://www.perth-wrx.com/vb/your-driveway/20621-ferals-06-wrx.html

I explored the same path you did, and unless you're genuinely serious about getting into track work and have the surplus cash to pay for endless repairs and breakdowns (most likely unforseen ones), save your cash and enjoy a few bolt-on goodies.

$0.02.

my advice, to you or anyone else thinking of going down this road....take a detour!

power (pun inteded) to ya if you go ahead with it!

maybe you can succed where many many others have failed?

I dont think this will be any different Ramon. Like all high end builds not everything stays in one piece all the time. The amount of stress these parts get from all the torque is bound to make things give way, but your not one i should be lecturing on this, hell, you are king of non-bolt on mods hahahahaha!

Be prepared is all i say, especially with a 2.5ltr build. See Trainwrexs about them, hes got one atm i believe.

Before you do this i would asj a few people with powerfull cars to take you for a ride in them. With that much power they become horrible to drive on the road. Heavy clutches, lag, bad ecconomy. Be happy with 200kw at the wheels and use that on the track. If it was me. I would go 2l as well.

before ya do this ide look at the 06 sti for sale in the cars section with all the ducks nuts cosworth crap already on it... sell your car and buy that.. its not your own build but if thats what your aiming for you will save yourself alot of hassle probably money and you will also have a real sti not one of the many copies out there.

my opinion and definately what i would do in the situiation, no one gets money back on mods so you may aswell be the one to reap the rewards.
