lol, while I would love a vehicle like that (power/weight wise) I am doing my absolute best to turn the exterior styling into that of a family sedan. Im looking into scoop deletes or revese scoops and a new trunk.

Scoop delete should be easy as you'll be using an FMIC rather than the stock top mount.

Is that 600 rwhp? what kind of rwtq? Or are you rating at the "flywheel."
LS2's and LS3's with a bolt on supercharger and no real supporting mods other than intake / exhaust make mid to high 500's to the wheels. That's not bad but still doesn't get you to 600 rwhp.
However, their power under the curve will be a world of difference than that 600 peak hp from the WRX.
Also, V8's are easy to get to 600HP. My cobra is a 480 rwhp / 500 rwtq to the wheels and that only took about 1400 dollars.
What he has done probably took 10,000 dollars, and I already have a built engine stock.

Can you recommend any? Ive been thinking about the KSTech delete, but Im not sure the look suits the '07 body style. The only other once Ive seen is the Seibon reverse, and its not really in line with my subtlety goal.
Also, do you happen to know if anyone makes a delete package for the rear window roof mounted spoiler? Ive been looking without success for awhile.

thats half the fun isnt it The most common failure is a cracked ring land which results in loss of power only. Im hoping if I get a failure that it is limited to that. You are correct though, when I drop in the built engine I should look into scatter shields and driveshaft loops.
That is 600bhp, and that is based on the dyno available to me here, where a stock STI dynos 220awhp, so I should be around 450awhp and 450awtq.
I am quite familiar with american V8s, we have a 6.0L Corvette and a 4.6L Mustang -- and I am absolutely confident that your statement about making 500rwhp without supporting mods is possible. At the very least you'll need larger fuel injectors.
Without getting too cocky too I would bet that my 450awhp STI would outperform a 500rwhp american car in pretty much all catagories.

Well, unfortunately for me my expenditure is much higher than it should be, because I already built it up and had it professionally tuned once for 400/400 bhp/tq -- I thought I would be happy with that.
The bad part is that all the parts that I bought for the 400/400 build are not useable on the 600+/600+ build.... so Im out twice, ahh well, my mistake.
I do not keep a running total of the budget because it would be too depressing. If you want to know the cost of specific components I can tell you though
just ask.Jeese. If you already had a Vette why didn't you just slap a low boost 7-8 psi supercharger on it?
It's not like fuel would be a big issue, changing the injectors is cheap and easy. That should still out run the STI in the 1/4.
Not saying STI's can't be very fast cars as I recently had one outrun me to 100mph, as street tires and 500 rwtq don't mix.
What kind of mustang 4.6L? All I have is a 4.6L too, but it's 4 valves per cylinder and has forged internals.

Im not so sure it would outrun the STI, what are they getting in the 1/4mile? Also, I am aware it would just be an injector change away -- I was more referring to the point you made about not having to do any supporting mods -- these injectors would be a supporting mod...
Umm. Well, a blown LS3 vette I've seen run 10.4 at 136 with a 7 psi supercharger on stock engine.
No suspension mods, intake and full exhaust. He had quite a bit of room left it seemed.
There is no way on earth I see a 450 rwhp STI trapping 130+, power to weight just doen't make sense.
I don't know the import world at all though. What does the car weigh?
What kind of torque do you get down low? I make 470 at 2600 rpm.

Yes sir, there are plenty of 450awhp Subarus full weight trapping in the mid 10's, usually at 130mph, as any more requires a shift into 5th.
Full weight STIs weigh in at 3450 or so. The 60' time with a decent driver will be in the 1.5s
Interesting I guess. but a 550 rwhp C6 vette will out run that WRX all day.
a C6 with driver should be 3400 pounds full weight, so with a 100 hp advantage and same weight it should be no contest.
You have both cars, try it and see!
1.5 60 foots is strong for sure, put a couple of Mickey Thompson slicks on the back of the vette and you'll pull mid 1.6's with a good driver.

because one could make XX HP for X dollars doesn't mean all can..also 480 HP is a lot different than 600HP.
600HP is never easy really for most to hit.
I am assuming you have a 2003-2004 Cobra...they already came built from the factory with much of the stuff you need built in....
pretty rare set up.

Aboslutely the 03-04 cobra is a rare setup.
However the only thing that truly sets it apart is the built engine. Everything else isn't too different, it's got a T-56 6 speed which is about the most common transmission for sports cars.
There are things that need to be replaced if I was going to track the car.
600HP is easy to hit in a Cobra KB or Whipple and you're set.
1000 HP in a Cobra would be the equivalent to hitting 450awhp in his STI.

A BUILT engine is what sets EVERY car capable of high HP apart.
I think you need to learn more about boost though...it's never just bolting on the unit nor slapping on a different pulley.
Fuel and ECU mods are almost always needed at the minimum.
Also many in the cobra crowd quote non-dyno HP from bolt ons added to the factory rating which was not wheel HP.
They are fast cars, but most aren't putting down the quarter miles many claim.
I don't know what you'd need to replace to track a cobra though other than brake pads and tires....

No it's not. You don't have to have fuel upgrades always. I don't have any fuel upgrades.
You clearly don't know much about cars. ECU modifications means you TUNED the car. Most people do that to any modern car whether they supercharge it or not. On my 06 mustang gt i "modified" the ECU by "flashing" it with a handheld tuner. A fucking monkey could press the two buttons on the device to do it and it was dirt cheap.
Same thing for the Cobra, except I had an SCT chip put in instead of using a handheld tuner.
Ok, to get 600 hp in my car I'd need bigger fuel injectors, a larger MAF and a KB or Whipple plus a new tune.
Most people on the forums I browse at svtperformance.com have dyno'd their cars. From experience, even if they weren't dyno'd and only had mail order tunes everyone knows a pulley swapped cobra with intake / exhaust is going to make about 450rwhp / 460rwtq
In general, of course you do want supporting mods when doing a big upgrade, like forced induction. But it's easy to slap a supercharger on a new mustang GT, Vette, etc. and make high HP with building the engine.
What are you talking about they aren't putting down the 1/4 mile times people claim? There is a bigass list of people on the STOCK Eaton supercharger who have recorded 10 second time slips.

huh wat...most aren't tuning?
Flash is a tune BTW...only a few cars can be flashed though.
I never said no one ... I said most.
People like to brag on forums. There was a pretty recent case where some guy many had respected was found out he never did half the testing he did and was making up numbers.
The dudes that are all turning 10 sec 1/4's still have IRS? They are definitely not stock.
This is the first recorded 10 second terminator though

Just changing a pulley on a 03/04 Cobra without retuning the ECU is asking for a melted piston. At the very least the MAF transfer table needs to be rescaled. Once you go over 14 psi (eg anything more than the stock blower with the smallest pulley) it gets really tricky because of a EEC-V hard coded max charge air value of 1.9 that clips anything higher. Then you have to lie and hack all over the place to keep things under that (like specifying injector size smaller than what you really have because you have a fake load curve that maps 0-2.5 into a 0-1.9 scale). Tuning is extremely important. The stock fuel system is good to about 600 RWHP volume wise.
I wouldn't track a Cobra without redoing all the suspension bushings and mounts, both front and rear, and without a set of weld in sub frame connectors. It's a totally different car. The stock bushings are too squirmy and even just spirited driving on the street you can't always feel where the car wants to go. With some good tires you can really feel the body trying to float away from the suspension under hard cornering. This is one of the many areas where SVT lost the argument with the bean counters and was forced to go with less than desirable. IMO the only thing that should be moving relative to the body of the car are the wheels and the control arms. Interior panels rattling are normal and to be expected, the suspension clunking and creaking through powdered rubber bushings under load is unnerving. A higher, fixed ratio rack and solid u-joint steering shaft address the usual complaints of numb or sloppy steering. YMMV.
