Damn you turbo dudes!!! You make so much more power on the same boost levels... im jealous but at the same time dont wana lose the DD qualities it gives. As long as I can beat down a prius im happy

Another vote for act pp with oem disc. I'm not turbo but I am sc. I boosted my S starting at 125k miles. I now have 175k miles on it at 12 psi and making just over 400whp.
Turbo will certainly put more strain on the engine since it makes more power and boost earlier on but these engines are built incredibly well. As long as you have a good tune and good compression to start with the engine should last a long time!

Ok I'm soon to be running a afi turbo kit on 1000cc injectors on like 8psi so will see. I've herd of ppl with motors over 100,000 miles on 16psi running strong

+1 on the ACT with oem PP and bearings... ive used this combo for well over 100k miles and no problems.
