New FSP build

OK here's the deal with 3rd gen flywheels pressureplates and clutches.
The 1.8L that I have has a slightly smaller flywheel/clutch/pressureplate. The clutch and pressureplate are actually the same as the 1.6L Miata, however the flywheel is unique (different bolt pattern than the miata).
The 2.0L clutch and pressure plate are a little larger (same parts as the miata 1.8L), while the flywheel is essentially the same size and bolt pattern as the 1.8 Protege flywheel. The difference in the clutch is the number of splines- so it won't match the F-Type tranny. The key difference of the flywheel being that the bolt/pegs for the pressureplate are a little further out, and the ID of the surface that mates to the clutch is about 1/4" larger.
So you could use a 2.0L flywheel, and pressure plate should mate up fine, however you would need a 2.0L sized clutch disk, with the spline bearing from the 1.8. It would take ALOT of digging to see if this combination exists in the Mazda-part-world. Another option may be to get someone to build some kind of custom clutch-but who?
Unfortunately, I don't have the time for that now. So I'm sending back the Fidenza flywheel and 2.0L pressureplate. Instead I have just had the stock flywheel lightened and I am going to use an OEM clutch and the 1.8L "Showroom stock" pressure plate.
Transmission with LSD will be ready to pick up tomorrow!

Back from Valdosta
With the help of Kevin and Scott, I was able to get my car back together just in time to head south to the Dixie tour.
Currently installed are:
transmission:
OPM LSD
new mazda clutch and pressure plate
slightly lightened OEM flywheel (sorry, didn't get a measurement)
B&M short shifter
Kartboy bushings
suspension:
AWR coilovers w/ Bilstein shocks
Springs: 325# front, 600# rear
AWR 21.5 Rear swaybar
Stock front swaybar
AWR front camber plates
MP3 strut tower bar
new lower front control arms (OEM)
wheels/tires:
Diamond racing 14x8 (5"backspace)
225-50-14 Kumho V710's
other:
AWR front and rear motor mounts
The car feels pretty good on the street, not too stiff- very fun to drive and very stable handling.
the tour:
Although the car is not "complete" (especially in the adding power department) I was happy to get the car together so that I could go up against some top notch FSP competition at the Tour and get a feel for the new suspension and transmission mods. It had been a while since I had raced last, but that was pretty much the same for everyone.
I was able to get within 1.5 seconds each day of the winning honda civic (total 3 seconds back), and finished in 3rd place out of 5 in the class. I was pretty happy with how I drove, and the margin was about what I had expected given the amount of development for the car. If I was more like 2 seconds back each day, I would probably be doubting the potential of the car. BUT there is alot of work to be done and I feel there is definately some room to grow and be competitive with the faster FSP guys.
On the track the car was a little too neutral for my taste in that I had to left foot brake a bit to get the car to rotate and turn in. I made some adjustments to the swaybar and ride height but it still wasn't enough to get the car to oversteer how I'd like it to. Most of that I assume is due to the LSD making the car more neutral/pushy, so I have to try some things to get that corrected.
I'm a little disappointed with my wheel offset. After getting it on the car with the new suspension, it seems I could go another 1" or 1.5" in so that the tires won't stick out (and hit cones!). So I'll make that adjustment when I'm looking for a new set of rims (I'm also interested in how Justin does with the Hoosier 275-15's).
So still a ton of work to do to get the car a little faster. Overall I'm really happy with the potential of the car to be competitive. The best part is that it is really fun to drive!
Thanks again to Kevin for all his help on the project, and thanks to Scott for supplying the MAF sensor- I think its working OK now.

Where do you think you're at power wise?
Also looks like you could lose quite a few pounds in the front seat department.
Good job at the tour!

nice build up. the rims and tires look sweet on the car to
Thanks guys!
Right now my power output is "stock". I haven't got it on the dyno, but I think its in the low 90's at the wheels. In comparison, Justin is making something in the neighborhood of 130 at the wheels.
However, I am a little lighter than Justin- even without any weight reduction.

subbin for updates on the build

Seriously...everytime I'm on the highway driving to an event some ricer pulls up beside me wanting to race. My car was slow before I put 400lbs of tools and tires in it, but it makes it feel extra fast after you unload it.

FYI 13s fit over the brakes on my wife's 2002 LX with no problems. well...they are 1 13x8 with a 5in backspacing and the rears could use a 1/8in spacer to clear the trailing arms there. I'd go that route.......can you update to the 2.0L motor? Are they on the same line? The 99 es had 15s like my wife's 02 LX so I assume 13s fit there too. Also its a 4x100.
