I bought my FD out of CA.
When I asked how he got it smogged with a big cam and no cats, he said throwing a few bills at the referee works wonders.  LOL
As with most things in government, money talks.  :banghead:

Thanks guys!

That is just about the LAST car I'd have expected to be competitive in Rally Cross. LOL

Just to point out, it isn't rallycross. it was a TSD tour rally.
So car prep is really about just being able to comfortably drive unpaved roads fast and accurately.
big tires allowed me to really not worry about the road conditions (washboard/potholes/etc) and also not having a lot invested in the car helps with the "if i break this car no big deal" attitude which allows for driving pretty aggressively.

That's cool.  Sounds like lots of fun.  :D

Sorry to burst your bubble but CA has made it clear.....Prius only

Sad thing is, that there are those in CA who really do want that.   >:(

Big congrats, man!  :bacon:

It would be cool to build some channels in the diffusser to cool the turbos.  I assume you would run the coolant lines to the turbos as well?

Definitely water-cooling the turbos (and the Tial MVR wastegates, coincidentally), but I'm less concerned with them than I am with everything around them.  Keeping the manifolds relatively short and low, and heat wrapping/coating everything will help a ton.
Using the turbo inlets to depressurize the diffuser seems like a great idea though, until you discover on/off throttle porpoising (up/down oscillations caused by changes in front downforce).  Ironically the best place from an aero perspective to pull air from is the hot, large plenum that we call the engine bay, where the worst air is.

I can't really imagine that intake air volume would be enough to significantly change downforce at high speeds.  LOL

Your problems are all due to Mazda's new hearing protection system.  All other manufacturers will be rolling out similar systems in the bear future.
It is designed to prevent you from damaging your hearing by installing a nice sound system in the car.  ::)

The wedding night is the best part, but don't tell my wife I said that.   :D

The car's looking good.   We'll be praying for you man.

Welcome to the forum.

Nice looking car.  The FD is one of the few cars that I think looks good in white.

Chrome, even cosmetic chrome plating, is EXTREMELY hard.
Attempting to sand through it would be very difficult and time consuming, and would likely severely damage the base material underneath.

I'd strongly recommend finding a wheel in the finish you like, or buying a bare or painted wheel and starting from there.

Do you still have the wing?

Yes I do.  Sorry, thought I had replied to you.  Sorry.

What is the distance between the mounting pedestals?

What's the advantage to the LizardSkin over the Fat Mat?
It looked like the Fat Mat was installed pretty well.  Before I did all that work, I think I'd have just sprayed LizardSkin on the parts that weren't covered by the Fat Mat.

IIRC the steel rod is there to anchor the factory seat belt, and allow it to slide fore and aft with the seat.
Do you have a harness in your car?

Nice work on the plumbing. 
I always have to force myself to err a bit on the loose side on AN fittings, as well as npt threads.
It's easier to tighten them a bit more than to overtighten them at first and have to disassemble everything later.
Also, AN fittings can crack if overtightened.

Don't install the wideband sensor until you're ready to power it.
Running the engine without power to the sensor will kill it very quickly.

I like how you mounted the skirts, very secure and professional appearing.

I always liked gloss black centers and polished lips on many cars.  I had a set of that color 6-UL's on my silver and black Miata.  Looked great.  Too bad they discontinued that color combo.

One other thing, you might want to redo that surge tank bracket with beefier material.  The tank full of coolant weighs a good bit, and engine vibration will flex and crack that bracket pretty quickly.

Is the wing still available?  I sent you a PM a few days ago, but never got a response.
