Hello all. (I'm not sure if I should be posting this here or in a general engine building section but... ) I just blew a side seal on my s4 6 port turbo NA. 70 70 30 on the front rotor and it idles weird. Feel fine over 3000 rpm though. (weird) My car is a daily driver, but recently I have been really getting into drifting. (track drifting, no bs public road stuff). Anyways, I have a (as far as I know) running s4 NA core at home, that I took out when went to my first t2 engine. I have till christmas to decide what I am going to be doing to my core before I rebuild and install it. (yaaaa its going to suck doing it when it's so cold. )

Anyways, I would guess there are some oil mods, and port options that would be recommended for daily driver drifter. I will be rebuilding it myself, but I will most likely send out any port work to be done by a pro.

I really don't think it was the high compression NA rotors (since I Was only running 5.5 psi) that caused the side seal to blow. I think it was just the 120,000 miles on the motor.

Any opinions or recommendations would be awesome. Thanks.
