Sounds like you're leaning toward getting this thing, and starting your project. You're right that the turbo cars are much faster than the N/A's.
The reason I brought up the fuel pump, relay, and EGR valve, was simply that as long as I was going down the list of "usual suspects", I didn't want to leave anyone out.... :)
If there is a slow evaporator leak, whether you want to get into a complete dash removal or not, is your call. Most slow leaks can be accounted for with $10.00 a year worth of R134a. There is a lot of disagreement about anti-leak additives, and I have no comment.
As far as the ABS module goes, the other contributor who mentioned the possibility of wheel sensors, could certainly be correct. It would be worth your time to e-mail Vic Rocha... he responds promptly and professionally.

My wagon is a hoot to drive, and has been known to leave a "what just happened here?" look on many a young face behind the wheel of "modified" Honda. Not that I'd ever engage in informal street racing... no way... never happen... uh-unh.... heh, heh.
Just for the record, I also have 205/55 16's on my car... I've just recently put on a set of Falken Ziex all seasons, and I'm absolutely thrilled with the performance.... particularly in the wet. Smooth and silent. Also, in the event you have come across it, don't pay too much attention to the often repeated "fact" that the 55 section tires will rub in your wheel wells... that advice is accurate, but pertains primarily to the lower "R" suspensions. You'd have to hold the steering against full lock, and then go into motion to get them to touch. The turbo rims, known as "Columbia" rims, are rare here in New York, so I decided to keep mine rather than going to somewhat more (?) attractive 17 inchers with low profile rubber. The turbo rides hard, and the taller sidewalls take all the pain out of the ride.

I used pricing primarily from the FCP Groton site, just to make the research easier. I went through the same exercise for myself, as I decided what to do with a 107,000 mile 96 turbo wagon. Since it now has 113,000 on it, I guess my decision speaks for itself.

Please keep us posted... I'm sure, just by looking at the responses, that there others who will be as interested as me, in seeing how your project progresses, assuming that you decide to go ahead.
Now, get a new tub of Gojo hand cleaner, and get to work!!!

Best of luck
