After 130,000+ miles on my engine it is still going strong but i think its still not strong enough. Is there anything that i need to do freshen it up internally now that I have this many miles? I was thinking about ordering a set of roller rockers/valve springs and stuff since my old ones might be getting loose. All my sensors are fine and I replaced the opti, waterpump and plugs about 10,000 miles ago. Tranny also just got rebuilt about 10,000 miles ago. (mods in sig) Any tips or recommendations would be nice. thanks.

 

If your car still runs 14.0s, then chances are that you're making close to the same amount of horsepower as you were when new. Mine still runs in the 13s at 84k, but is also lighter than yours too most likely (and I've got 3.23s)
