My 2005 sti

[8cd03gro]

I have gotten a few PM's asking about my car so I figured I'd make a thread. Hate it or love it here it is.



On E85 it made 295whp/333wtq @ 18psi on a very conservative dyno dynamics @ 5,000 ft with a 1.15 correction factor. Should be more along the lines of 325/380 on a dynojet. Stock LS3 make about 340 on the same dyno for reference. The car weighed 3430 with me in it, a half tank of E85, and the heavier wheels on. We could push it to 20psi and make more power, but this is my track tune so I need it safe. Once winter passes I'll be dropping in a new short block and a 3076r to shoot for ~475awhp.





Will be on KW clubsports, adjustable sways, and Hankook RS3 next month FedEx willing. And yes, I hate the wing, but the car feels very unstable at speed without it, so I have to figure out something else before I switch it out.

Cool car!

What did it dyno stock?
And what did you do to it (and cost) to get 295awhp?

I might pick up a STi for my family car in a couple of years.

Nice car! I've always liked the styling on that particular generation of WRX STi. I'm not too fond of the newest generation.

On the subbie though, I like that wing. Not to mention it comes stock with that wing for a reason (as you pointed out)

Thanks. I didn't baseline the car, but sti's are tuned there all the time and the owner (Harvey) told me they tend to dyno about 220awhp and similar torque stock, give or take a few depending on year and conditions. I am running quite a few engine mods in anticipation of the bigger turbo setup, but the mods that are really making power now are

Catless helix downpipe ($100 used)
Grimmspeed catless up-pipe with 38mm tial external wastegate (~$600)
ID 1000cc injectors (~$500)
Invidia Equal Length Race Header ($750)
3 port boost control solenoid ($120)
Walbro fuel pump (~$100)
E85

Here is the whole list, but a lot of the parts make no real difference in power and are there either because I got a great deal or because I will need them down the road anyway. One could make the same or similar power with just the mods above and a good tune. The stock turbo is the limiting factor. It just runs out of steam. You'll notice I make peak HP at about 5,500rpm, then it starts to fall. It's a hell of a power curve for road racing though.

-Beatrush gold airbox (JDM YO! )
-ID 1,000cc
-T1 top feed conversion fuel rails with line kit red/blue fittings
-Helix catless downpipe
-Grimmspeed 38mm EWG up-pipe with MVS wastegate (red)
-NGK 1-step colder plugs
-Walbro 255lph fuel pump
-tactrix 1.3
-SPT catback
-Invidia equal length race header
-Torque Solutions billet pitch stop
-Grimmspeed 3-port BCS
-Turbo blanket
-GMS turbo inlet
-GSM Air/oil separator



It's a great DD and would make a good family car if you're not trying to squeeze 5 adults in. I can drive it to the track, run down some very quick cars, then put on the blizzaks and drive it through 6 inches of snow no problem.

Yes, the car looks odd without something there, but I want something less flashy and attention-grabbing if I can find something functional for the track. You are right though, it is definitely there for a reason and it's surprising how effective it actually is.

This is what I want, but they are damn near impossible to find

1000cc injectors wow!, usually putting 600-800 is a decent improvement for the STI. Stock is like 540 or something if I remember right. I'm hoping to pick up a WRX in a few months for winter here, and then heavily mod it during the summer (alaska). I had one before, it was tons of fun.
