Default TopSpeed Motorsports Built 2016 STi Rotated GTX3076R - 463 whp

Car: 2016 STi
Location: TopSpeed Motorsports, Alpharetta GA
Tuner: Taylor @ TopSpeed Motorsports
Dyno: Dynojet linked AWD
Transmission: Stock 2011 6-speed
Gear: 3rd
Peak hp at rpm: 406 whp @ 6,400 rpm on 93 / 463 whp @ 6,300 rpm on E85
Peak tq at rpm: 359 wtq @ 5,600 rpm on 93 / 421 wtq @ 4,700 rpm on E85
Baseline for stock STi: 2015 STi made 246whp/253wtq on 93
Target boost: 20 psi on 93 / 22 psi on E85
Fuel: 93 & E85 (Cobb Flex Fuel)

This next car I’d like to share with you all, I really like… like a lot. Ha! This customer initially contacted us last year when their 16 STi was new about doing a few simple bolt ons and we happily did. The car made 302 whp and 347 wtq with the following bolt ons:
  • AEM Cold Air Intake
  • ID1000 Injectors
  • Cobb Fuel Pressure Regulator
  • Cobb Fuel Pump
  • Invidia Catless DP
  • Cobb AccessPORT

After several months of having their car back and then riding in my car (400 whp on E85 at the time) they inevitably were after more power. Being that we did some very simple upgrades the first go around and they wanted the option to go bigger down the road so we talked over the idea of going with a rotated turbo kit vs a stock location upgrade; this would leave the option to go a lot bigger later without having to completely change the setup. Luckily, they also have E85 available in their area so we went with the Cobb Flex Fuel kit which would allow them to run either E85 or 93 depending on what they had available. After some discussion, a final plan was put in place to do an ETS Rotated Turbo Kit using a GTX3076R, ETS Front Mount Intercooler Kit, our TSM SS1 Shortblock, and the various supporting hardware for those items (full listing of parts below).

The owner has had this thing back for a few weeks now and they are super happy with the results (so are we)! Before we dive right in to the numbers, let me preface this with the owners wanted something super conservative and as reliable as it could be so we purposefully left a fair amount of room for error here; none the less, I still think that how this thing sits is great for a daily driver and is a TON of fun to drive.

I know the owners plan to do some drag racing and are coming out to a half mile event in January with us so it will be cool to see what she does in those arenas as well.

Full Mod List:

TSM SS1 Shortblock
  • Diamond Pistons w/ Skirt Coating
  • TSM Custom Tolerances
  • TSM Expert Hand Assembly
ARP 2000 Headstuds
Killer B Oil Pick Up
IAG Air Pump Block Off Plates
NGK One Step Colder Spark Plugs
ETS GTX3076R Rotated Turbo Kit
  • DEI Titanium Turbo Blanket
  • DEI Titanium Heat Wrap for Uppipe and Downpipe
ETS 3” Core Front Mount Intercooler Kit
  • TiAL Q BOV
  • Omni 4 Bar MAP Sensor
  • AEM IAT Sensor
  • Visconti SD Conversion Harness
Competition Clutch Stage 3 Segmented Ceramic Clutch Kit
Invidia Q300 Catback w/ Stainless Tips
Cobb Tuning Flex Fuel Sensor Kit
Cobb Tuning EBCS
Injector Dynamics ID1300cc Injectors
AEM 320lph E85 Fuel Pump

That car must be a lot of fun to drive!

Nice early torque and good power to redline.

Nice one.

That's some nice numbers on low boost levels.

Are you still running the stock fuel rail and lines?

Yes, this is still using the stock fuel rails and lines. We typically don't recommend upgrading those until 500whp+

Correct, this is on the stock header. That's something they will likely upgrade at a later time.

I haven't seen many people at all using diamond pistons. Great company! How do you feel they compare to the more common names in the Subaru community? Manley, CP, JE etc?

Honestly, at this level they are all going to be very similar to each other. Some are noisier than others but that's about the largest discernible difference between them all at this level. That said, I do like how the Diamonds install and how they run in the vehicle as compared to some of the brands we've used in the past.

Very nice!
Question -
I'm curious to see when the ID1300s+AEM 320 pump max out on E85.
So if you don't mind what are the IDCs at redline and have you kept the stock fuel pressure?

Sorry for the late reply - we've been in full event prep mode and it's a little hectic around here ha.

IDC was 83% @ 43.5 base fuel pressure (this was simply using the Cobb FPR kit) on this setup and should allow enough room to make just over the 500 whp mark before you'd need to upgrade the pump.

Impressive, those newer STIs sort of lack style, but are speed machines at least. I have been looking at the '17 WRXs.

This setup would likely make the same peak power on any 2004+ STi.

The 2015+ WRX's are awesome but they have a different engine with their own list of advantages and disadvantages.

Thank you! So far all I've heard back from the owner are great things about how it drives and how much fun the car is. The reality is that with the lower torque number, this setup will last a long long time so long as it's maintained well.
