Whats the intake manifold spacer and fg throttle body adaptor about? Arent you using the fg intake manifold?? Or do you mean the adaptor wiring harness? Is thr spacer meant to increase runner length or something? Fg inlet runners are plenty long? Nice to see somebody quantify their build to the dollar for all to see like that, cant help but feel you shouldnt though, for your own sake more than anything haha.. Exciting times ahead mate, looking forward to seeing you finally get the result you have been chasing all along.
