The Six Conversion:
2.7 CIS with 993 cams, 46/40 valves, 911S 8.5:1 CIS Pistons with Nikasil cylinders. Guessing it produces slightly more than stock 2.7S HP and has a much lower, broader TQ curve. Current exhaust is stock 914-6 HE's and one of Ben's SS Quiet mufflers. Been very happy with the exhaust note the past few years, but always wondered if stock would be quieter. Ben's Quiet Muffler ( I did have to reclock the tip as it was more for 1974-up 911): Attached thumbnail(s)

With my 3.2 most of the noise came from the fan and chains. The 3.6 is way more quieter. I only hear my obnoxious M&K two in two out muffler. I wouldn’t have it any other way!
