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)

QUOTE(technicalninja @ Jan 8 2025, 12:31 PM)  $225 for custom dual pane laminated glass seems CHEAP! Way cool upgrade! I'm interested in how well this works for noise reduction. Some modern cars come with dual pane safety glass with a dedicated airspace for exactly this reason. Those aren't laminated with the glue layer. following. Summer time is great - winter is a little noisy in the cabin with top on and windows up. Running a 3.2L |
