Hi fellow turbo-dodgers. I have been into these cars since the 80's, owning a 86 S/C since 1988 and #0235 since 2000. The S was in very clean condition when I got it in 2000 with about 46k miles. I put a little TL&C back into it, and it was actually featured in Hemmings Muscle Machines magazine in 2005. Unfortunately, it has been sitting ever since and now I want to "re-recondition" it and this time, take it to a 10 out of 10 car. Ok, maybe a 9. It is 99% in it's original state as when it left the Shelby plant. It now has a whopping 48k miles, so it will never see a ton of miles. But when I do take it out, I would like it to be reliable and not worry about the A-525 exploding or the lightweight rods bending.
Driving it to it's new location quickly reminded me that even though she's been sitting in a garage all this time, this is still a 27 year old car. So the question is since I plan to go through every inch of this car, how much change would you do to a car in this state? I don't plan on going over 14 psi on a Stage II LM. Maybe add 2.5" swing valve and downpipe. Should I go with some TII rods and pistons and a A520/555 (using a rod shift kit) with moly plate and call it done? The block should be ok with quality bolts/studs. It would be nice if I could keep her internals as is, but not sure if I will end up making things worse if/when the lightweight rods and/or 525 fails?
