Well as you can tell from my sig, my hatch is a daily driver and so i put alot of miles on my new motor. When my GSR reaches around 150K, i know its not gonna be as strong as it was when i first got it. It has 73K miles now... but the way i drive, i put on 3K every 2 months. So... my question is, whats actually needed to keep my investment healthy when it does reach the 150K mark? Should i have it completely rebuilt, from top to bottom. Like port and polish, new seals, etc. Basically everything internal should be replaced im guessing? this way, i can still run either a heavy 9psi turbo application or a 50shot of NOS. Im trying to get ideas now so i can start planning, and start saving in case it is gonna be expensive. any info is appreciated.
