What turbo was this with?

I have an 05 and I'm thinking about going with a 20g or something slightly smaller...just looking for ~325 whp to keep things conservative.

Blouche TD06-20G. Still has lots of low-end, with a massive mid-range and top-end.

my daily driver is a 2008 stage 2 Subaru WRX....love it!

I took my chipped 2011 STI to High Plains raceway last weekend for the Porsche DE event and wow the car has an amazing suspension setup from the factory. I was struggling with what to upgrade in the suspension before I tracked it, and now I'm even more torn! Subaru did an amazing job making the suspension miles and miles better on the 2011 versus previous models. I was consistently running just as fast laps (or faster) than any NA 996 at the event. The only place they'd get me was on the straight I'd max at about 115 mph while the NA 996 cars would get up to 120-125 with their better aerodynamics.

I might go for some upgraded sways, and maybe some shorter springs and stiffer dampers, but the car had so little body roll already that it's going to take a lot of money spent on it to significantly improve upon what Subaru did with the latest model. Bravo Subaru for finally making the STI suspension what it should be!

It's not going to stop me from modding it of course. As most of you know it's an addiction. I'm thinking of swapping the downpipe and putting a tune on it to support that, and then doing the sways and springs/struts. It'll already run under 2 minutes on the track consistently, and this was my first time there. I bet I could get down to 1:50 with the changes without too much trouble. Anything under 2:00 at that track is considered a very good time.

Go with the full Invidia header, uppipe, full turbo back exhaust, intake and a pro tune,

Upgrade your sways and add a pair of coilovers like the RCE Tarmac 2's

Change your brake pads and fluid and have some fun.....

If you want a really good small turbo for the stock location use the DOM 1.5XTR and have it tuned for E85....Should net you about 430whp and 475 torque with the same turbo spool as your stocker.....

What's your experience with these cars? Because some of your advice doesn't make sense to me.

1. Why upgrade the uppipe?
2. Why upgrade the headers?
3. Why Invidia?
4. Why put on coilovers for what's mostly a street car?
5. Where are you getting your HP/TQ numbers? And how do you think stock internals are going to handle those numbers reliably?

430whp? Good luck. Those stock internals will take dump quick.

Header upgrades are touted as giving a 10-20hp increase if you go with equal length (EL) setups. The up pipe isn't really giving a gain, but you do that at the same time to ensure compatabillity with the header and turbo.

Not sure why Invidia was suggested for the header, as there are reports of fitment issues... The Tomei seems to be the most popular unit to go with, as it carries a lifetime warranty and gives good gains. FWIW, I have an Invidia divorced DP sitting here, and am waiting to pull the trigger on EL headers, and then will send the whole lot out for JetHot coating before install next spring.

Turbo upgrade with yeilds over 400whp will pretty much require upgraded internals. 350whp is consisted the max safe limit for stock internals, and even then you are looking at reduced durability/longevity if you are matting the gas all the time.

The best bang for the buck go-fast-mods for the STi are: TBE, ECU tune, E85....

Best bang or the buck handling mods are sway bars and weight reduction...


Anything after that is open to debate as far as what to get next or is better mod...

We just had a subie vs Evo event at my local track. Great looking car but still love the evo 8s.

E85 will do a good job at preserving the weak ringlands that plague the EJ motors. If you want your motor to last 100k miles, I'd be cautious at anything over 350whp on the stock bottom end.

Teflon....sorry I have been away.....Some of these questions have already been answered.....

I gave you some sample products that could be good for your car.

If you do decide to do the upgrades here is what I think is the best on the market currently.

For the header and up pipe I would go with Killer B and also get their oil pan, baffle and pick up as they are designed for track use.

For the turbo back exhaust I would go with a company called Nameless Performance out of Washington for their complete turbo back exhaust.

For E85 you will need to upgrade the fuel pump and more than likely get 1000cc injectors so you have some room to grow. I would also consider a fuel pressure regulator at this time as well just to get it over with and there have been a few issues with stock fpr.

For the suspension I still recommend sways and the coil overs of your choosing based on your budget.

Brakes are simple, upgraded pads, fluid and stainless steel brake lines if you would like.

You can do an intake, but it is mainly noise unless you get a CAI and then you might get a few horsepower.

Get a protune on your Cobb Access Port from a reputable tuner. The stock internals are going to be good to roughly 450whp for track days as long as your tune is safe and you have VERY limited knock. Possibly invest in a turbo blanket and heat wrap headers and downpipe. I would assume you would drive around 95% of the time on a street tune at roughly 300-320whp.

Turbo upgrade if you want one Blouch 1.5XTR, ATP GTX3071, HTA FP Green are all very viable options. Possibly look into a 38mm external waste gate on your up pipe with either the ATP GTX3071 or HTA FP Green.

If you are going to change the turbo, upgrade internals and do everything else, don't waste your time or money with a stock location turbo. Go rotated, and call it a day. Nothing smaller than an HTA GT3586.

Lmfao @ 450whp on stock internals
