that will be close to what i have:

350# front springs (slightly lighter than yours)
450# rear springs (effective rate should be almost identical to your)
square wheel/tires setup (what you plan to run)

what sway bars do you have? i am running 968 MO30s

if i remember correctly, my spring rates are roughly the same front to rear ratio as an OEM car without a sway bar. my intention was to use the swaybars to dial out understeer. unfortunately, the car has been somewhat unpredictable. i think it is a result of some very cheap tires.

Dan what size is the speed hut gauge? I think I am going to order one and eliminate the speedo cable.

Can't wait for some on road and dyno results of these engine builds Dan.

Dan, any thoughts on this:

[ideola]

How about some more weight savings while we wait for the replacement rod bearings to arrive.

Complete stock headlight setup, all hardware, with original OEM Euro H4 light assemblies, motor, lifting bar, buckets, covers, etc. = 20.0 pounds

Claude's fixed headlight conversion kit + Hella H4 head light assemblies = 6.6 pounds

Total weight savings = 13.4 pounds



Will wait to install until after the motor goes back in.

I believe I have a diagnosis on the low oil pressure situation. It appears to be incorrect bearings. Long story short, I have two of the 2.2L stroker setups, one for the UWB and one for this motor. Apparently, only the UWB stroker was done as standard-standard (main & rod journals); the second crank, which went into the Club Sport motor was turned down to 1st undersize.

I must have measured the wrong crank when I installed it into the Club Sport, so it got standard bearings. Fortunately, I caught the low oil pressure right away, and there was no damage done to any of the components. In fact, the standard bearings that came out don't even look used...they still have their original coating intact.

Last week I was able to get the new .25 OS bearings installed for both the crank and the rods, and got the motor all reassembled. Yesterday, I was able to get the motor dropped back into the chassis. I still have a lot of work to do to reconnect all the ancillaries (rad+coolant hoses; fuel system; DITC and a few other electrical connections; exhaust system). If things continue at the current pace, I hope to be able to start the engine next weekend, and then finish the TMCC installation.

Dan, now where did you get .25 under mains? Those things are no where to be found!!!!

w000ooooooooooooo000000000000000o000o0o0o000ttttt!!!

Engine is back in. Finished the install this morning. 5 quarts of Brad Penn SAE30 Break-in Oil. Re-filled coolant. Fired it up. (Had to tweak the DITC ignition distributor orientation). Voilà!

8 bar of oil pressure at initial cold startup (it was COLD this morning ... only 10°F when I started working, and I forgot to store the oil in the heated garage ). Ran the temp up to the first tick mark to bleed the cooling system. Settled in @ 4.5 bar of oil pressure at ~1000RPM idle.

It's supposed to be dry, partly sunny, and 40°F tomorrow. And it's President's Day, so I get the day off. I plan to get the front suspension bolted back up, swap on the correct rear coil over springs, and then do some rolling road break-in cycles. Very excited!

Oh yes, I also got Claude's (924-76) fixed headlight conversion installed, so if the weather and suspension work cooperates, I'll snap some pix of that too.

Next up: plumb in the coolant circuit for the TMCC!

The CS is once again moving under its own power

We were granted President's Day as an official holiday this year, so I took advantage of the day off, combined with a dry 45°F partly sunny day. Got all of the suspension bits bolted back up (although if you look at the pix closely, you'll see that it's in dire need of an alignment!!!). Put on the front bumper, put on some D90s shod with roller tires, buttoned up the dash electrics enough to drive it, and took it out for a few break-in laps around the neighborhood. Sure felt good to drive it!

Still have a lot of work to do:

• Install aux fuse block
  
• Permanently wire in the GPS speedometer and the boost, AFR, and oil temp gauges
  
• Fine tune the panel gaps with the hood and fixed headlight conversion
  
• Install the windshield trim
  
• Fix the Euro driving / fog light wiring (had been badly hacked by the P.O.)
  
• Alignment and corner weighting
  
• Plumb in the coolant circuit for the TMCC
  
• Apply the sun screen to the windshield and rear hatch
  
• Apply the Club Sport graphics

We wiped it down after the celebratory laps. Notice the fixed headlight conversion (kudos to Claude / 924-76 for the amazing kit!) and the corrected ride height. Still waiting to put rubber on the satin black Club Sport wheels, but these D90s give a good approximation of how the design of the wheel works with the whole package.
