The New TPC20 Turbocharger for the Audi and Volkswagen community that hosts one the most popular compressor wheel of this generation of Garrett turbos such as The G25-660 POWERMAX Stage 2 turbo.
After many hours of design and months of machining TPC made custom parts for the TPC20 to host the G25-660 54mm x 67mm compressor wheel without having to break the bank. On top of that we mated this sweet new compressor wheel to a GTX29 turbine wheel measuring 53mm x 56mm.

On top of having some of the best wheels in the class this turbo uses BALL BEARINGS which makes this turbo more reliable and faster spooling than it’s JOURNAL BEARING counterparts.
*The New TPC20 was built for circuit, road racing time attack cars that is looking for the quick spool and V8 like power to get out of the corners which we find ideal for most tracks. But if you change tracks later on to a power track you can simply swap out the turbine housing to a TPC38 hotside and you now have a whole new power delivery.*
Note: The TPC20 and TPC25 use the same internal parts. The only difference is the turbine housing which plays a big role and puts the powerband where you want it. The TPC20 uses the OEM IS20 hotside and the TPC25 uses an IS38 housing. Stay tuned as we will soon do back to back testing to show you the power delivery options that best suits you.
You can choose from 2 styles of compressor housings, the OEM or Upgraded version.
About the upgraded version: The 2 piece intake system is far superior than the OEM models as shown in the pictures below. The opening at the turbo’s inlet is approximately 1″ bigger then stock and has a nice angle inside the inlet portion direct the air flow where it needs to go. The inlet on the performance cover is also available with an OEM style PCV fitting or a -10AN PCV fitting for easier catch line installation The result means better air delivery to the G25 compressor. For those to it matters, the TPC upgraded elbow is also 3/4lbs lighter then the popular “best flowing elbow on the market” which is made of Stainless Steel. For most racers every 3/4-1 lbs matters.
If you choose our upgraded compressor housing , to help offset the cost of your new purchase, If you already have an upgraded turbo inlet pipe and turbo muffler delete you can sell them as this TPC upgrade will come with either a 2″ pipe pipe welded on the compressor housing for people running an OEM sized TMD or a 2.25″ pipe for people with a discharge pipe from brands such as Neuspeed, AFE, and EQT. If you are unsure as to the size of the turbo muffler delete you are running measure the OD at the serrated portion of the TMD.
WHEN ORDERING THE PERFORMANCE COVER PLEASE PUT WHAT SIZE OUTLET (OEM/2″or 2.25″Upgraded) YOU WOULD LIKE IN THE NOTES SECTION OF THE CART.
