Hi all!
My friend plains to buy SC stage II kit for his RX-8 hi-power. I'll mount kit in his car. I'm familar with haltech EMS and turbochargers for FD/Cosmo but still newbie with RX8 and SC.
I did search and found blitz and pettit kits. A pettit kit looks more interesting.
What do I need to complete the kit (BOV, piping, fittings)? I wrote to Pettit but still no answer.
Can Int X log wideband (LC1) and EGT? Have it closed loop lamda control? What I need to do with second lamda sensor? Does Pettit have base map for stage II?
Thank you!

You don't need anything to complete the kit. Positive displacement superchargers don't use blow off valves. They have maps for the Int-X for their kits.
