Im modifying Xcessive P11 plenum kit for my friend with SR20VE swapped N15. Car has custom Tri-Y manifold, 2.5" exhaust, N1 cams and Nistune ECU.
- longer spacer to get more runners lenght
- oval velocity stacks to add runners lenght and better airflow
- Q45 TB with 45° angle pipe
- 3.5" intake pipe with built-in MAF sensor
- 3.5" custom velocity stack with JWT filter
I will post more pictures later, when project moves forward. Im hoping for better results than with "stock" plenum kit.
