Well I've decided to go ahead and do the mods for my 87 930 here's what I came up with, based on what I have heard on these boards. This is based on a stock 87 with the exception of an Andial IC that was installed by a previous owner. The car is in great condition 83000 miles compression and leakdown numbers are all good.
1. K27 of some description don't know which kind (need help with this one, the car will retain CIS and will not be tracked) K27HF "S" maybe?
2. B&B Headers with heat
3. 1 bar spring or should I stay with .8?
4. Monty muffler 75mm or 100mm?
5. LC1 AFR gauge.
Would appreciate any comments or thoughts on this setup, and what am I missing? I plan to order the parts in the next day or two
