There's lots of debate over turbo sizing and may leaning towards bigger turbo's now, so I thought I'd post pics of motor before it gets freshened up w/ set of Wossner pistons.
My sled has a Peak Powersports 2860 turbo setup. I usually run around 10 lbs of boost . Been running avgas blend for last 700 miles or so, race blend previous to that. Pistons came out of sled my old man's XP (it's getting a big old set of Wossner pistons in it!!) and had about 500 on them. Around 1000 w/ boost.
Scratch was on pistons when I installed. Let me know what you guys think. More to follow.
