ZTR, Here's the best advice anyone can give you since you're new to Zs: Put your $5,500 in a 3 month certificate of deposit and spend that time researching. Use the search function on this site extensively, buy the "How to Hot Rod..." Nissan engine book, and talke with Dave Rebello at Rebello and Jim Thompson or Chet Whittle at Sunbelt. Good luck!

Make sure that whatever 4 point harness you install is designed and certified to be used as a 4 point harness. DO NOT install a 5 or 6 point harness and leave out the crotch straps. In a hard front end accident you will submarine under the lap belt and jam your knees real, real hard into the firewall.

The only way you're actually going to know is to bumpsteer the car. http://www.thedirtforum.com/bumpsteer.htm -
Funny, a Californian (me) found this on an Iraqi blog site: The following list of rules apply to each person as they enter Texas. Know them and learn them. Pull your droopy pants up. You look like an idiot. Let's get this straight, it's called a 'gravel road'. I drive a pickup truck because I need to. No matter how slow you drive, you're going to get dust on your Lexus. Drive it or get out of the way. We have pigs, cattle, and oil wells -- that's what they smell like to you. They smell like money to us. Don't like it? I-20 and I-10 go east and west, I-35 goes north and south. Pick one. So you have a sixty-thousand dollar car. We're real impressed. We have quarter-million dollar cotton strippers that we drive three weeks a year. So every person in every pickup waves. It's called being friendly. Try to understand the concept. We all started hunting and fishing when we were nine years old. Yeah, we saw "Bambi," too. We got over it. If that cell phone rings while a bunch of doves are coming in, we will shoot it out of your hand. You better hope you don't have it up to your ear at the time. Yeah, we eat catfish, and crawdads. You really want sushi and caviar? It's available at the corner bait shop. The "Opener" refers to the first day of deer season. It's a religious holiday held the closest Saturday to the first of November. Any references to "corn fed" when talking about our women will get you jack-slapped, by our women. We open doors for women. That applies to everyone regardless of age. No, there's no "Vegetarian Special" on the menu. Order steak. Order it rare. Or, you can order the Chef's Salad and pick off the two pounds of ham, turkey or chicken. When we fill out a table there are three main dishes: meats, vegetables, and breads. We use three spices -- salt, pepper, and Tabasco sauce. You bring "Coke" into my house it better be brown, wet, served over ice and plenty of it! You bring "Hooch" into my house it better have 4 legs, a tail, and have a nose for quail, dove, duck, teal, or pheasant. You bring "Mary Jane" to my house she better be cute, know how to shoot, drive a truck, and have long hair. Yeah, we have sweet tea. It comes in a glass with two packets of sugar, some lemon, and a long spoon. High School Football is as important here as the Lakers and the Knicks, and a dang site more fun to watch. Yeah, we have golf courses. Don't hit into the water hazards -- it spooks the fish. Colleges? Try Texas A&M. They come outta there with an education and a love for God and country, and they still wave at passing pickups when they come home for the holidays. We have more Navy, Army, Marines, and Air Force than any other state, so, "Don't Mess With Texas". If you do it will get your butt kicked by the best! Our military is only used as a back up. Per capita, each man, woman, and child owns at least two firearms and has taken a NRA Certified Shooter Education Course. Also, remember what Governor Sam Houston once said, "Texas can make it without the United States, but the United States can't make it without Texas."

You'ld never sell 50 sets. Basically, there are 20, maybe 30, Z guys across the US that are willing to spend serious money on their cars to get that last bit of performance.

There are lots of machine shops that would be glad to make 280Z stub axles and companion flanges. They can even make them out of 4340 or some other high strength steel. Unfortunatly, there's no market to support the manufacture of those parts. Don Potter used to buy new 280Z stub axles and companion flanges, radius, shoot peen, polish, and heat treat (basically blueprint) the parts and sell a complete set for $1,000.00. I know of no one ever breaking those special parts and the few that I know exist are hoarded by the owners. Don stopped doing it shortly before he fell ill because no one was buying them anymore. A short run (20 sets) of stub axles and companion flanges made out of 4340 would probably cost at least $20,000.00 including design, machining, broaching, polishing, and heat treating. Anyone now willing to pay the same $1,000.00 per set that Don was charging?

That's for one TV and I think GM has spun off DTV. Back when Moss Software existed we did some billing software developemnt for DTV (which was part of Hughes).

NA 3.1L=>head & camshaft questions. No shortcuts, max
johnc replied to zredbaron's topic in Nissan L6 Forum
Lay off the beer and go read your source again. Typical oil temps on a street car are around 150 to 175F. If your chrome valve cover is adding 200F you're looking at oil temps beyond the design limits of any oil that you or I can purchase. On a race track you start worrying if your oil temps exceed 240F for regular oil and 275F for synthetic oil. With no air flow through the engine compartment you will see high underhood temps (typically 100F over ambient) but once a car starts moving over 20mph underhood temps drop to something like 10F over ambient. I saw a test on a Ford Contour using multiple temp probes that confirmed the above. The 240Z, with its more open engine compartment, should see at elast a similar reduction. -

You've got to be joking, right? -
I remember: Jumping off the neighbor's roof into their pool, our own high dive, when they weren't home. And then getting spanked by them when they turned out to be home. Playing "war" with BB guns and actually shooting each other. They leave a nice welt. Riding our bikes down into the big storm drains (in Brea) and seeing how far we could go before the drains got too small (in Santa Ana), then getting lost and not making it back home until 9:00pm. Had our bikes taken away for a month. Sneaking into the closed Nike Missle site in the hills above our house and crawling into the demo'd silos. Climbing on top of oil well pumps and riding them as they went up and down (got caught doing that and the local cops decided to lock us in the cell until our parents came and got us). Saving your money from March until July so you can buy all the fireworks you possibly could. And then spend the rest of July just barely avoiding burning the neighborhood down. Attaching razor blades to the outside edge of a Frisbee ('cuz Gary Spriner heard his older brother talking about it) and then realizing there's no way to throw it. Getting spanked with belt at least weekly and learning how to fake cry after the second swat. If you fake cried on the first one, Dad would know you're faking and would give you a few extra good ones. Living in fear of the Mother Superior and her paddle while going to Catholic school and having that fear realized more then a few times. Building our own skateboard ramps out of ratty plywood. FYI... this was back when skateboard wheels were clay or metal. Those were the good old days, but I remember always, desperately, wanting to "grow up." Sometimes memories are deceiving...

Yeah, Porsche parts are expensive, but in racing they last so over the course of a season or two, Porsches are generally cheaper then most cars that run in the same classes.

Sorry to hear about the bump, but that's no reason not to bring the car to the MSA show. You're not backing out that easy We can put a chair in front of the damage so no one can see it or you can claim you got bumped by Dale Jr. after you lapped him at Cal Speedway. I showed my 240 last year with a dented hood after Bryan bumped a BMW at LVMS.

Looking as best as I could at the lower control arms it appears the front is so low that the control arm is horizontal. That's not good for handling and you'll get a lot of steering kickback. The rear seems better but I can't tell for sure. Both the front and rear control arms should be angled down at static ride height.

I was down at Erik Messley's shop last night and he mentioned that the 240 adn 260 companion flanges come with a gold colored washer and the 280 companion flanges don't. That washer is exactly 1mm in thickness (measured one last night). I guess this adds a little to the mystery. I only know of the 25 and 27 spline stub axles. What's the third one?

And why is this thread in the Turbo/Supercharger forum. Its moved to Drivetrain...

I'm running 280 stubs and companion flanges in my 240 hubs and I ran the spacer that came with the hub (didn't have the 280 spacer). I used the installation procedure listed in the manual and ended up with something like 205 ft. lbs. of torque if memory serves me. I don't think think the stub axle length is different, but there may be differences in the 25 spline and 27 spline companion flanges.

Well... the bearing spacer is designed for the hub the stub axles are installed in. Although I've never swapped 240 stub axles into a 280 hub, I've done the reverse and used the "B" spacer that almost always comes with thr 240/260Z hubs. I wonder if the 240Z stub axle is shorter then the 280 stub axle? Maybe you over torqued the stub axle nut? The manual says to torque the nut to 140 ft. lbs. and then measure the bearing preload with a spring scale pulling on one of the wheel lugs. Keep increasing the stub axle nut torque until you get a reading of 25 to 30 ounces on the spring scale. Then stake the stub axle nuts.
