When it comes to aftermarket turbochargers for this particular platform, Blouch Performance Turbo is among one of the more popular choices among enthusiasts because they are built using careful manufacturing methods to produce a more powerful direct bolt-in option. On this page, you are looking at their TD06H-20GXT-R 8cm2 billet ball bearing turbocharger. The new XT-R line of turbos from them consist of a billet compressor wheel to optimize the aerodynamics of a turbo and increase compressor flow within the same inducer geometry. Which allows you to build more horsepower at lower boost pressure.

The key features of this turbocharger include a 48 lb/min fully machined billet compressor wheel with a high-efficiency Garret GT turbine wheel with the Garret GT full ball bearing system with an adjustable upgrade wastegate actuator that is calibrated at 19 psi with an 8cm2 turbine housing. 

Included with this turbocharger will be the coolant and oil drain pipes, along with a stainless steel oil feed line along with new gaskets and hardware to make this turbocharger ready for the installation.

EXACTLY what I needed
Seanhavok253 4 months ago
After ditching a very dated and abused vf39, this turbo paired with an ETS top mount, id 1050cc injectors and an amazing tuner ( Mike @ PIA Tacoma ) we were able to manage to squeeze a very respectable 410whp out of this turbo at only 22psi with peak boost at 2950rpm. I’m still on stock internals and did not want to go further, but the turbo showed zero signs of running out of breath any time soon.

Excellent turbo!

I have a 2006 wrx with an sti drivetrain swap, this turbo, Perrin turbo inlet hose, K&N intake, Grimmspeed Uppipe w/ EWG 40mm, Godspeed Catless Downpipe, 3in CNT Catback Exhaust, Perrin EL Headers, ID 1300cc fuel injectors, Walbro 255 fuel pump, Turbo XS 50/50 BOV, Turbo XS FMIC, Grimmspeed EBC. Out the box, it is a great looking turbo, almost feel bad to put it in. Install was easy and everything fit right. Had the car taken to Cobb Tuning in Plano, TX. Put down 359 hp to the wheels with 379 lb ft of torque. Running 17.5 psi on E85. Very quick spool up and once it kicks in, puts you in the back of seat. Would definitely recommend this turbo to anyone looking to make safe, good power on stock internals.

The more I run this car, the more I love this turbo. I have yet to explore the limits of this beast. Currently running on an 06 STi with water meth, 850cc inj, EL headers, 3 turbo back, 2011 STi intercooler, factory air box with K&N drop in filter. It easily pushes 23-24psi all the way to redline with WGDC's around 60% on a gm 3 port. I was even able to advance the timing a few extra degrees up top. I am confident that this turbo has enough flow to overrun what my stock block will be able to handle. This will be ideal for when I build my destroked 2.4L

They've made it better.
roadtrip109818961 4 years ago
I just got one of these this week. After reading the past reviews, I feel it is necessary to write an update. -They increased the length of the outlet on the compressor side (so now your stock stuff should hook up without any additional parts). -It comes in a very nicely finished black powder coat. It really is beautiful. -I'm not sure if they've increased the wastgate size, but I haven't remapped from my 16G yet and the boost is very predictable, no creep and no spikes. It does spool slightly later, but not bad at all. I cannot wait to start tuning for this thing. -I also ran into the intercooler issue, which I resolved by using a bolt that was a half inch longer and putting an extra nut on the back side of the intercooler bracket. No extra hoses, plenty of clearance. -Many of these reviews are older. They have increased the compressor wheel flow rate since. This should be at least on par with the 20G XT now.

Great upgrade
sti_pwr156 5 years ago
2006 STi with this Blouch 20G turbo, TurboXS FMIC, DW 740cc's, Walbro 255 pump, GrimmSpeed EBCS, Cobb AP Pro tuned by MillerSpec in LV, Nevada, HKS RS intake, Samco inlet, Invidia EL headers, GrimmSpeed 38mm EWG up pipe, Invidia V2 DP, and Invidia N1 race CBE. This turbo feels much better when compared to the VF39, lots more useable power and a broader powerband. Quick spool up and hits hard clear to redline. Install was not bad, minor issues and took maybe 2 hours from start to finish. Great upgrade and definitely would recommend to anyone looking to upgrade.

    I have an 05 legacy gt. I've read/heard from different source's that this turbo will fit my car if I have an fmic (which I do) would you say that statement is true?

    • A: It would depend on which FMIC kit you have, but this could fit with certain front mount setups on a Legacy GT.

    I have the traditional PW tmic, and I was wondering what else do i need to make this turbo compatible/fit my current intercooler set up?

  • Q: Fitment  Eric 3 months ago


    Would a Cobb boost controller fit with this turbo

    • A: The Cobb EBCS will work with this turbo, but both parts require a pro tune.

  • Q: Difference between 8cm and 10cm  WRC fan 7 months ago


    The 10cm version of this same turbo is rated at the same 440hp. What is the advantage of one over the other? I'm looking for quickest spool and maximum torque on my 2012 STi with Cobb intake and Cobb downpipe.

    • A: 8cm is a smaller exhaust housing and will spool quick compared to a 10cm housing. However, the 10cm housing will have better top end.

  • Q: Blouch 20g xtr ball bearing turbo   Subieghost02 1 year ago


    Does rally sport direct or Blouch sell center cartridge seals for compressor housing and turbine housing on the blouch 20g xtr ball bearing turbo ?

    • A: We do not, generally when you have to replace the seals you have to get the turbo re-balanced and most company's wont sell the seals out right to customers.
