I beg to differ
I ran a 125 shot on my car for years and years but not with a SC. Yes, eventually they can't handle it. At just over 100K mile on your car and if its in good condition, I wouldn't be too afraid. That kind of mileage and its not even broken in yet if its been taken care of and well maintained.
You are running the SC on the car now correct. Any problems with it thus far?
I'd start with a dry kit 50 shot and likely keep it there. You could stretch it to a 75 but that would be as far as I'd ever push it and not all the time at that. Get it tuned with the juice on it also and see how it likes it and make sure things are good on the tune. Make sure the fuel pump has been upgraded. You certainly don't want it going lean.
As far as the pistons, yeah they aren't the best. I do believe I've read someplace that the 93's 4V motors had a better piston (Thicker) than some of the later years but don't quote me on that. Nick McKinney may be able to provide more insight there.
Like anything else, you beat the piss out of it all the time its not going to last at all. Just the way it is. If you can live with that and be conservative to a point it may last a long time. If not then be prepared at some point to put a forged bottom in the car and be ready to roll.
Hope this helps you out. Good luck with your project and keep us posted.
Just my experience and .02 cents!
