Duh, my fault. Domestic market would be Japan and not the US. We are the import market. No go on the 1992.

What about US 1992 Verts? There's gotta be some around anyway. I know that's what wikipedia said, so does that mean the vert was not sold in the US in 1992?

Hmm....here is the Stock rule:

"Stock (OEM) vehicles are defined as those equipped at their original year, make, model and equipment level specifications, without factory options."

If I interpret this strictly, that means we have to follow 86 Base specs.

Spoilers are points
Power Steering Removal is not a point
Engine must be the S4 13B Motor for no points, otherwise, it's an Engine swap?
Single Piston Calipers are standard
Steel Hood is standard from what I gathered.

This makes me sad.

I can't imagine the 86 Base would weigh 2625 with a steel hood though. Where does it say, on Mazda's official documentation, what hood each model comes with?

The 92 US verts were still VIN taged with 91 numbers.

They didn't even bother to re-stamp them like they did with the 90 GTUs model.

This is like an IT rules thread, you are getting skewed in your '86 thinking though. Look at the update/backdate rule, we are fine. I even emailed Greg about the VDI and got it approved for wiring open, it's only on the S5. Bottom line, the rule can be summed up like this... (for the RX-7 13b classing)- Any part found on a S4 or S5 NA base model for that production year, US market only, is considered OEM and can be used without a point hit. Furthermore, any part listed in the no points hit list can be used without penalty.

Edit: Check this out, the technical bulletin is out on the VDI and 6 PI. We almost lost the ability to do that mod, took several emails and facts to make my case. http://www.nasaforums.com/viewtopic.php?f=16&t=20844

why are you even doing that mod? No low end (sub 3800 rpm) corners or just trying to remove the air pump?

It never had an air pump as it's actually an S4 car with S5 rotors and intake along with S5 bumpers/tails. The engine compartment is stripped as bare as possible. The VDI is wired open, only is good for 5200 or so and below. No need for the 5th/6th sleeves either, those are something like 3500 RPM and below. You know all that though. Removing the rods and sleeves has the potential to increase flow, or at least it can't hurt at the higher RPM's. It's been on the dyno more than once and makes great power. All my real power is between about 6000 and 8500 RPM, which is where the motor only operates. The 5.12 rear helps keep revs high. The only time under that RPM is in the paddock. This car is stripped to nothing more than a shell with the essentials on it. It's not a track car, street car, nothing but a trailered full blown road race car.

So there were no model year 1992 verts? Damn....If Mazda only sold a 92 vert, I'd be happy.......

Looks like it's still single piston fronts and solid rears for me then.

Hmm....well, since the rules make no mention of VIN, does the fact that the car was sold brand new from the dealership in 1992 allow for the classification by the vert? Probably not, since that's quite a bit of a stretch, but it could be a technicality. I guess model year is determined based on VIN number.....

I guess it doesn't matter if some came with aluminum hoods, as long as Mazda officially says that the cars can come with just steel or with either aluminum or steel on the base model. If it's the former, than boo, if it's the latter, than yay! Can anyone verify Mazda's official stance?

thats kinda strange too...i have a 91 vert fc...says so on the build tag
but on the title the vin number comes up as a 1990...its strange...the guy
at the dmv said some early models will be sold as a year before if the car was
on order but not built and delivered till the next model year will still be tagged as the year the vin was ordered, so through my people at dmv he said theoretically
with something like a convertible if so little were produced in that year that most likely production of the verts stopped in 91, but some were built in 92 to take care of the original customers.
