I own a 1989 7M-GTE with a 3” downpipe and a LIPP turbo elbow. Both cats have been removed, leaving the stock resonator and muffler. The section of pipe between the resonator and muffler is flat on the bottom; it does not have a round cross-section.
What should I do to complete the upgrade...
I have had two '89 Supras and the boost gauge "jumps" when I accelerate rather than increasing smoothly as the turbo spools. Not sure if it is a gauge problem, sending unit or other.
Would appreciate any solution.
