51 T on the rear, Vortex Ecu from Parsons Motorsport, Screen less Filter Cage (Ebay) with a Uni Filter - Rush Filter or use the Twin Air Powerflow Kit, Modify the Air Box & Cover to allow it to breath & Exhaust. I have a PC Slip On with these above mods & it is way better than the 19 - 23 motor. 🔥 Keefer Testing has just done an Akro V PC Exhaust review worth watching.
