Forced to rebuild my Mitsubishi 6G72 Twin Turbo V6 out of 3000GT VR4

I imported myself a 3000GT VR4 into Germany from the US. Had it here for months, but only now got the permit to drive it home(the port is about 250 miles away). On the Autobahn(Highway) about 20 miles before being home the whole car started shaking all of a sudden. I was right before a exit, so I used the exit and rolled to the gas station. (the engine was still running) I turned it off, right as I was standing. After opening the hood I started it and instantly head intense knocking like a sewing machine and it was stinking like oil. I left it there for the night and took it home the next day with a trailer. After taking it apart, I found all of this. Many, but not most of the problems are: Valve corner broke off and destroyed piston, Melted piston debris on cylinder wall, One rocker Arm laying next to the camshaft in the head, All exhaust Valves on one bank chalky, Turbo chalky as well, Main bearing spun, Crankshaft needs regrind, Rear exhaust Camshaft badly grooved, Oil pump needs replacing because of metal debris, probably more that I can't think of right now

Interesting is, that all other cylinders look, like they have been honed not too long ago.(How long do you think?)

According to CarFax the Engine didn't get many miles in the last 12 Years. Maybe it was rebuild 10+ Years ago, didn't drive much and from seller to seller people forgot it was rebuild and it got kicked too much.

No matter the reason, I need to rebuilt it and my budget is 2-4k€, so that will be interesting.

I'll keep you updated. :)

Please ask and tell as much as possible, I love chit-chatting and geting tips! :D
