First time poster, long time autocrosser out of Austin TX. I've met a few of you in RL but mostly hang out on that other forum.
Yeah so my 97800 mile Gen2 (2016 GT PP1) is dead. We'll open it up in a few weeks and see exactly what happened, but right now the theory is the rod knock we heard and seized motor were probably from a spun bearing. Not sure if the oil gears failed or what, but I'm expecting to have to rebuild/replace the crank and a rod at least. Lifters have been making noise when the oil got a little old for a while now.
I'd love to rebuilt it a bit stronger and faster. Setup was Gen2 with ported 18 manifold, ported TB, E85, injectors, Steeda closed intake and a tuned RPM bump to 7800 to get a higher autox top speed in 2nd gear. I think it dynod at close to 420 rwhp. Also have GT500 valve covers to help with dumping oil through the drivers PCV side.
Its mostly used as a 2nd gear autocross car and occasional HPDE toy and spends a lot of time riding close to the redline. I'm not entirely settled on staying N/A versus adding a blower on there. I'd be love to get closer to 500hp than to 400, but honestly 600hp sounds about perfect for my needs. The power I had was good, but I want at least a little more. I haven't done headers yet.

- The recommendations seem to be to start with a Gen3 block and then work with my Gen2 heads and engine control?
- Gen3 aluminator short block or stock Gen3?
- Any love for a 5.2 build? (are GT350 heads needed for that?)
- I'll switch to a better oil pan (GT350 or GT500) with a good pump and gears for sure. I'm assuming the '16 GT steel pan wasn't doing me any favors.
- Any cams worth the money over my stock Gen2 ones?
- FP high performance timing chain stuff, I assume is worth it.
- Any headers good for low end torque? 1 3/4 long tubes?
- Anything else that should be on my radar for reliability spending time near a ~7800 redline?
- I also have major frustrations around fuel starvation even when 2/3rds full going left with my aero and sticky tire setup. I guess I should leave that for another thread.
