3.4 996 Engine upgrade

[jsceash]

A couple suggestions. I'm running A 3.6 LN Boxster motor and 5-Spd for 2 years. Still in the 5 speed because the change to a 6 speed requires many changes, Suspension supports, bearing carriers, axles, rear transmission mounts, calipers, rotors,

1. Find a 2003 or 2004, 5 spd they are a little better built, and also allow the 2003 2004 axles.
2. The 2003 and 2004 axles are heavier than the previous generation. They have a 10 MM through hole in the CV joint instead of 8MM. Although the thread on the 10MM shouldered bolt used on the 03 and 04 is still 8MM threads, it is not difficult to retap the holes in the flanges for a 10 MM bolt, and use a straight 10 MMx45 bolt. I opted for 3/8"-24 X1-3/4" 18/8 Socket Head Cap screw. This also stopped my shearing off axle bolts.
3. Porsche did not make a 23 spline 23.8MM spline dia. clutch disc that is sprung. You need to go after market, Clutch Masters or Spec. Look under Boxster on Pelican they sell one 88-1861-000-017-M410 Sach sprung clutch disc for ASSCO plate.
4. Buy a heavier sprung pressure plate also I'm using a Spec level 2.

My 3.6 sleeved motor ran on the 2.7 L program. Before I was done running it in I had Softronics modify the program. I want to run the motor before I started changing other operating parameters.
