Joels isnt in the car atm. He hasnt got an r33 either, its a r32.
Mine has a pod filter, Q45 AFM, 550cc inj, bosch 044, 600x300x76 intercooler, os twin plate, r33 gearbox, single piece tailshaft, high flow rb20 steel wheel turbo, 3" front pipe & 3" cat back. Engine...well lets say no change from over 5k....forgies, balanced, ported head etc....
thats it. I dont know af ratios....thats how much i trust the tuner, Shaun. He ran it to check afr's then had to pull fuel from the AP Engineering base map.
Only doing 1000ks with negative pressure, then dump oil, change check afrs again, then go to 5000 (varying revs, under load to 5k max) another oil change, and a full power run all out
Not that i cant wait to give it some now ....it truly does have INSTANT spool (ie positive pressure) on the rb20 turbo....unbelieveable compared to the rb20....
