Depending on your ability I'd say rebuild. At 77K miles I decided to rebuild the motor with 034Motorsport forged internals (bottom end) and titanium valve springs and retainers. Besides a slew of other FBO parts to include a TTE810. My goal is different, but ultimately you'll be building a more confident motor. Strong bottom end, eliminating valve float. Other than that, the only issue I had was a failed thermostat at 44K miles.
i really like this upgrade, I thought it said it was for the ea839 though. Were there any installation difficulties? You do it yourself? How difficult was the whole job if so?
I like your thinking, rebuild it better (and probably quicker) than original.
How many miles do you have on your rebuild and have you dyno or track tested it?
The rebuild is at 77K. I'm in the middle of the build now, and will be dyno tuning at the end.

That's for the 4M.5 turbocharged engine I guess. The OP has the 4M supercharged engine.

You're correct sir! However, I was just pointing him in the direction. Additionally, 034Motorsport bottom end upgrade kit has been installed in the SC motor by a guy I know, and they also have upgraded cams for more power for the SC motors.
