What do YOU plan on doing to your car?

Well, as you'd expect, it's a multi-year plan. And since it's just a plan, it's subject to change without notice, typically when it bumps head-first into reality.
2006 Enhance suspension
Shocks & related
Pilot Sport
strut brace
possible M030 option upgrade as well
2007 Enhance transmission reliability
quaiffe LSD
Hardened 1st & 2nd gear, beef up the bearings (?)
racing CVs
2008 Enhance engine performance (targeting 300 wheel HP)
racing cams (?)
Chips / engine management
port, polish, flow the head
exhaust upgrades (ceramic coated headers, etc.)
lighten flywheel (?Fidanza? )
oil pan gasket, baffles, crank scraper, improved oil pickup
drill extra oil passages in crank
Race / Pro-street Clutch (?)
MAF upgrade (?)
2009
Forged rims & new tires, Front: Tire 225/50 ZR 16 Rims: 7,5 J x 16 H2, Rear: Tire 245/45 ZR 16 Rims: 9 J x 16 H2
Brake upgrade if needed
2010
Start working on paint, interior, AC, cruise control, etc.
Notes:
Plan is subject to change without notice.
Plan is subject to change based on the impact of reality
Plan timing is very aggressive, and some parts may be delayed
======
The end goal is to have an S2 that is close to running with the stock turbo 944s, very reliable, stout and strong, and fun! I want to be able to break the rears loose at will, and occasionally make some smoke, and leave some tracks.
The target HP may be very optimistic (what do you think? I'm all ears!). It may very well be that later in the plan I'll have to do some sort of forced induction upgrade, putting me on par with a turbo 968, but that's a lot of money for HP that it would be difficult to use as these setups typically come in around 400 HP. Still, I'd really like to hit the lower end of super car performance range.

Doesnt the S2 run with a stock turbo up until 100 though? And then the Turbo takes off. There is a chart of performance figures floating around the list that show them being extremely similar to that point.

A stock S2 is a match for a stock turbo. Not exactly mind you, but pretty darn close. I have done plenty of street drives with S2s and even in my Turbo S they hold their own just fine. True the turbo is faster, but even the S is only slightly faster. On the track PCA classes stock S2 and Turbo in the same class. The Turbo S lives with the 968 on class up however. Get on a track and you will notice the S being faster, but not so much on the street.
The low end torque and throttle response all the S2 to make better use of his hp on the streets. Once a Turbo get a chance to get into the boost it should pull the S2, but that will be only slightly. The Turbo S however should take the S2 in most all cases, but it will not be by that much.
Remember Flywheel hp ratings
Stock S2 = 208 hp
Stock Turbo = 217 hp (only 9 hp edge, but has lag)
Stock Turbo S = 247 hp. (39 hp edge, but with lag)
All three cars are of a similar weight.
Of course a lighted modded turbo will walk away from an S2. 300 rwhp is bit much for an S2. Maybe for an all out race motor, but gaining over 100 rwhp from anything other than forced induction will be hard.

Yeah on a track its different! Or on the highway! The turbos pull faster and harder once you get past 70.
Then again, Turbo charge an S2 and you end up with a monster!
However, turbo noise is neat...but the 16valve whine is awesome. I love hearing the S2s and 968s!

I am going away to school for so I won't be driving my Porsche. I'll just be storing it. Before that happens I would like tint the front windows, then get new plug wire mine are arcing really bad. Then just drive it once a month.

The S2 trans has a lower final drive than the 951 trans as well as a taller fifth gear (36:28 = 0.778 vs. 35:29 = 0.829, respectively). First to fourth are the same.

Well! You learn something new every day! Thanks!
Umm, but as far as holding up under higher engine torque, that's about the same for both transmissions. I mean they are more constructed alike rather than different. It's just a gear ratio change. Right?

Now - May 2006:
Finish building & install 3.0L turbo motor (K 26/6) - Bloodraven's old motor
Install new Clutch
Get Tec3 setup working
Either rebuild power steering (fix dozen leaks) or replace with manual
Dec. 2006 - May 2007
Suspension upgrades (Coilovers / Swaybars / Bushings)
Brakes upgrade - Big reds? (for looks) or Rennbay willwood kit (for budget)
Large turbo / 3" exhaust
2008 +
17" or 18" wheels
Somewhere in there I need to budget about $2k worth of bodywork too now though :-/

Somebody @ 944 fest (forget who) was claiming that the S2 transmission isn't nearly as strong as the turbo transmission, and that they've seen numerous high-power cars blow up S2 transmissions, yet survive on turbo transmissions.
