I did a gt30r upgrade on my redtop sr and the shop that made a custom downpipe welded in a o2 bung on it but its much bigger than the stock o2 sensor so i was thinking maybe a z32 sensor would fit, would it plug right in? What other bigger o2 sensors would plug in? I think he made it a bigger bung so that he could plug in the wideband when we put it on the dyno instead of having 2 bungs. Any help is appreciated.
