Just found out my turbo (the primary) is having problems. Low boost with oil in it. This is basically a stock R-1 with DP and Intake as the only mods. Which turbo solution do you recommend? (I do intend on putting an intercooler and cat back on the car as well as a power FC and fuel pump.) I would like to stay sequential and unfortunately have to stay relatively smog legal (canceling the single turbo idea). Would you opt for stock rebuild, stage 1, or stage 2 from BNR? Or the Petitt Racing High Flow rebuild? Or .................?
Thanks for the input.
