Clearly I’m a have not when it comes to the below so here we go:
88 Pistons:
Issue – These have become extremely scarce, I have seen 1 or 2 sets for sale on the interwebs in the last 12 months. Other than buying an entire car (which is not cost effective) these are hard to come by. The power numbers can be made with low compression pistons; however more work, time, and money are required. Additionally, even though you may hit the total number; the HP and TQ may not be evenly distributed and the timing may be different compared to just using high CR pistons. I feel as though I am building a suboptimal product in comparison just because a specific part is rare.
Solution 1 – Designate one aftermarket piston as spec that will be sustainable. Either have 10.2 commissioned or allow wossner 10.6. Over time as engines are rebuilt most competitors will gravitate to the new pistons. Follow the same rules of using a restrictor plate to max at 138 (+2). That being said, having a company supply 10.2CR pistons would be preferred. Cost difference would not be significant (e.g. 88 pistons: ~$300, new aftermarket pistons ~$600, getting a low compression engine to 140 with dyno time and tail chasing in parts $$$$).
Solution 2 – Someone who has a set sell them to me
