That's my 98(215hp), 12v, 3000 governor springs, #10 plate slid forward, boosts 39lbs, clocked fuel pump & adjustable fuel pressure banjo bolt. Did the upgrades around 240k, currently about 513k. It dynos 432 HP & 860 ft/lbs torque at rear wheels. Other than a slightly heavier clutch, everything else is stock otherwise, no head studs, stock turbo, etc. I keep a close eye on the egts, never letting get above 1300°, although on heavy pulls up mountains, I've rested it on 1250° of a few straight minutes. It's nice to have the power & extra revs when you need it, but the longevity is all about how you drive it the rest of the time. In the case of the manual trans, the higher governor springs is probably the best upgrade I've ever done, I figured it would help with building the line pressure on the auto as well, but maybe not.
