When i put the turbo on I changed the valve seals, as they were shot, but I have a feeling the valve guides are bad too. It mainly burns oil at idle, but it is not so visible since I put a cat back on. I do have to add oil frequently, and it is not leaking externally. As for tires, i have 245’s on the back so I was surprised it spun so much. I hope to make it up to the track before season’s end on 9 psi, I will post the results after that. Yes, I have a wideband on it, I have it tuned at high 11’s for the air fuel ratio under boost, i want a bit of safety so i went on the conservative side. I’m not sure how accurate the safc is for knock counts, but it is generally very low until the motor gets really heated up. It is definitely a fun setup and I highly recommend it to anyone who wants a fun street car. Id richen it up a bit more if i were you to LOW 11,s. dont even bother with the afc for a knock reading, its very inaccurate… just keep in mind that ur probably very close too/maxing out those 370`s so before u decide to run more boost, invest in a meth injection kit,start off with a small nozzel(m7-m10) and work ur way up to a bigger size as u tune for more boost. Pay attention to ur base timing, redline etc and go to the dyno!!! based on ur dynograph u will know if ur getting any ignition breakup and also what rpm your power/torque falls off… great work and good luck --- _[View the full topic](https://forums.speedlife.net/t/ka-t-run/128150)._
