Your cage is very well designed and hell for strong. I wouldn't hestitate to use your car to ram Elephants out on the Serengeti...

Intake sizing would be very dependent on: 1. Aspiration type (N/A or Turbo). 2. Cam selection. 3. Valve sizing. 4. Port work. 5. Throttle body or carburation.

No, they are not interchangable due to the side shaft (stub axle) sizing.

A properly designed box ties into the floor pan, rocker, and rear bulkhead just like any properly designed main hoop plate. It does not just rely on the 22 gauge floor.

The safety advantage a box under a tube provides is that it allows a more normal load path into the tube (compression along the tube line). A tube that's notched or has an angle cut into the base adds a (admittedly small) bending moment into the tube in compression. I tend to build boxes under the main hoop in a 240Z and the prebuilt, weld in cages from Miatacages.com and Kirk Racing that I've installed in other models of cars also use boxes under the main hoop and front downtubes. This might be for safety and it also might be for installation/manufacturing convenience.

End the legs of the main hoop on the top of the rocker. You'll either have to run a plate out horizontally or notch the legs so they run down the face of the rocker panels for a couple inches.

Exactly...

IMHO, spring rates in the 175 to 225 range are about perfect on a street 240Z with good shocks (Tokico Illuminas, Tokico HTS, Koni 8610s, etc.). That's coming from a 48 year old man who drives a F350 every day.

Shocks contribute more to ride harshness then springs. What shocks are you running?

My guess would be 150 to 175 at the crank. I can ask Floyd this weekend if he remembers the build.

The guy in the Elise was a wreck waiting to happen. Early apex every corner, miss the corner apex every time, jerk the car around with the steering wheel, and then finally lifting off the gas in the corner - tank slapper, BOOM!

The washers were there as an inside joke. In the 2003 OTC Rylan and Aaron were running an off-the-shelf JDM rear wing on their Honda S2K and they adjusted its angle of attack via stacks of washers. Up to 25 in a stack! Found a picture: Instead of making spacers, curving the spoiler, or making filler panels, I added small stacks of washers and left them visible as a tribute to their Hillbilly engineering. On the track I filled in the gap between the hatch and the spoiler with white duct tape.

I think they are 10mm x 1.25 pitch.

I can understand her wanting to find a different guy. What girl would want to date a man with a leaky rear end?

Adding or moving weight outside of the axles increase a vehicle's yaw intertia (search on that term). On a 240Z, unless you're willing to give up the passenger seat area, a reasonable sized fuel cell needs to go behind the diff. Make sure there's enough clearance between the diff and the cell to fit a ratchet to remove the cover nuts. The battery should be installed somewhere within the car's wheelbase.

No cop in the world is going to step into that situation. Let it go.

Probably better. It was a bad ricer joke involving wings, scoops, and wheelchairs.

Works for these guys... EDIT: image deleted

I see a mistake. The diagram on the wall is of a Turbo 400, not a Turbo Encapulator.

A few things. Brake brackets for an offroad racing truck, suspension rocker pivots for Goldenrod, some other small parts. Yes. http://www.timet.com/fab-p27.htm

Argon is heavier then air which is something you need to consider when welding in some kind of container. Otherwise, is dissapates very quickly. FYI... When I occaisionally weld Titanium parts I use a big washtub that I fill with Argon before welding. As long as I'm not moving my hands around a lot I can get nice silver or light straw welds. Anytime you see blue or purple on a Ti weld, its contaminated. Makes you wonder about all those pretty bling, bling Ti parts...

I can't imagine how horrible the brake balance will be after installing these calipers. I don't see anything in their package that addresses this.

Here's the OSHA standard. http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=13096 Remember, exposure levels to any airborne toxin are based on quantity and time. A one-minute exposure to levels above the standard is not a big deal because of the time weighted average of exposure.

I'm guessing here... With a progressive rate spring I think you would be better off cutting the top coil(s). It would have a much smaller affect on spring rate. You would have to cut more coils to get x amount of drop.

Well, I wasn't driving the car when it made those lap times. I was a few seconds slower. And I meant the comparison as a compliment to the GTR. My old Datsun was loud, rough riding, hot, and pretty uncomfortable. In the GTR you have the climate control running, a CD playing, and your $5,500 per hour prostitute sitting next to you getting ready for the evening.
