It must have got really hot (?). Cracked some rings?

If this car is already track prepped (money already spent), it will probably be significantly cheaper to just replace the block in this car as opposed to a conversion or going to another platform and building that up. Maybe possible to salvage the existing block w/ nikasil coating (which is not a real cheap, but still an option to consider), otherwise find a good replacement short block. I would not recommend going down the path of sleeving ($$).

Also, need to consider future plans - do you ever intend to club race or just DE a track car. If you ever plan on racing, make sure any engine and modification decisions are done w/ consideration of the racing rule book.

Contrary to popular belief, 951 engines can be relatively reliable track motors if well maintained and properly tuned w/o going overboard with power/boost.

Yes, it got very hot unfortunately. There is excessive scoring on cylinders 2,3.
I do have some interest in working my way up to club racing, but going with a NA spec 944 might be better for me and a better platform for me to learn to drive.
Having said that, though, I'm not about to abandon the turbo since it is otherwise a good platform to rebuild and use as a track/DE car. I'm actually leaning toward to LS1 conversion path, but no decision yet - still too painful.

Shoot a PM to JoshB on here. IIRC he is parting an 86 951 right now.

This is the exact reason why I have an LS1 in my car right now. When I looked into rebuilding my motor vs sourcing another 20+ year old used motor vs the LS1, the LS1 made the most sense. Both financially, power wise and reliability wise.

The swap itself was fairly inexpensive once I sold off all the turbo motor stuff I didn't need and recouped a significant amount of money.

theres an lsx being built at behe performance with an ls3 v8 . sounds bad *** !!
