Emissions

[Skye's7]

Alright guys, I've never owned a 13b rew before, so this will be a new experience. My red s4 has a 13b Rew swap, jdm, with a little porting done to the runners. The previous owner ran premix and so I shall continue to do so, knowing it's probly not good for emissions. It's catless at the moment, but I bought a cat hoping it'll last long enough to get it through. Luckily I haven't had the cat installed so I'm not exactly if it'll work. It's tuned on power by Fc. Everything is stock on the motor execpt for the light porting and no cat. Oil pump is slightly working according to th previous owner so he premixed. From researching a bit, I know I'm going to be running the engine till it's fully up to temp, and for about 30 mins so everything is up to temp. Anyone got anybody on the inside? Ahha I don't want my brappag to go away...
