Turbocharging the 12V VR6

Here are my notes for adding a turbo to a VW 12V VR6 (AAA) Motor. Please e-mail me if you think I should add anything.

Selecting a Turbo

Commonly used ones :
  • T3/T04E 0.60
  • T3/T04E 0.57
  • Modified T04E 60trim in a .60 cover with a stage III wheel in a .63a/r. (Kinetics?)
  • T04e-57 (EIP?)
  • GT30r


Boils down to two general options : increasing the fuel pressure or using larger injectors. If you were to get into monster-turbo builds you would probably need a combination of fuel pressure regulator, inline fuel pump, and injectors.

On the stage I and stage II kits Kinetics/C2 goes for larger injectors on stock FPR and EIP goes for stock injectors and higher fuel pressure.

I don't know what I'm talking about. I only am a parrot to the information I can find out on the web. And we all know how reliable *that* is.
