Jager911, great question, because I just picked up the car two days ago.

I cannot report any numbers. Would I increase to 3.4L again? I'm not sure. The cost of just the parts for 3.2L to 3.4L conversion at a MINUMUM $2200 ($1200 to bore & plate the cylinders plus $700 for used 98mm pistons and $300-ish for rings), HP gain is the percent increase in displacement (6%=13 HP). It seems like there are a lot of other things that can be done that will give you more bang for your buck (cams, intake, chip & headers). But if you need new pistons, definately do it. My whole project (parts plus labor) came to about $7,000--which I consider very cheap. Unfortuantely, I will probably not dyno the car for awhile. I need to do some tuning and brake in.

As for the status of by engine: The stock flapper box is back on (took hotwire off). I did a couple of runs with a Gtech meter up to 5,000 RPMs. The Gtech and my butt dyno both say it is still not performing great. It seems to lack low end torque. It is easy to stall when staring out. I bought a wideband AFR gauge which I will install this weekend. I really don't want to do any driving until I get that installed. Last night I checked the WOT switch--it is not clicking and is rotated full counter clockwise, so I'll fix this first.

I plan on going through the whole Motronic system ensuring everything is operating correctly. I made a list of stuff to check, but off the top of my head:
- Fuel pressure
- Vacuum leaks
- Idle control valve
- Pull plugs look at color
- Disconnect O2 at idle and check RPM change.
Basically, go through the "Motronic Tuning" thread, and check EVERYTHING.
