86951Turbo

Who makes them for the 86 951? what's the largest size a cylinder can safely be bored out to? I just picked up a block, which was advertised with cylinder "scoring." I asked him if he could catch a nail on the "scoring." Said the bottom end is perfect. Finally recieve the motor, and it's more like gouging. Dissasembly will commence on Satruday, but I'd like to research prices. If all fails I'm sleeving my orginal block with the cracked #3.

Thanks in Advance

Just recieved my 951 Turbo Short Block. Dilemma.....The block was advertised as having scored cylinder walls on #2 and #3. I just checked the block out, in the dark, and it seems more like gouging. I looked at the piston and my guess is that there was detonation and the conrod was bent. #2 piston looks like it's just resting on the cylinder wall. Do i know this for sure? no, i'm just preparing myself for the worse. Saturday will reveal the whole story.

Now, I can probably bore it out to 104mm from 100mm. that'll get me to 2.7L. Usually, this is done with resleeved cylinders. The other choice is a 101mm bore. That is if 1mm overbore will clean up the "scoring." The problem the oversized pistons will require custom pistons and wristpins. This spikes the price of a set of pistons to an outrageous amount. Options #3 is to resleeve the block in the car with Darton M.I.D. sleeves and reuse the rotating assembly with new rings for the iron sleeves. This was the orginal plan, but outside influence brought me to this point. Lesson learned....just do it the way you want to do it.
