That's the price for the basic CF/Nomex race hood with a primered finish. That's the price for the basic fiberglass hood with an inner frame that let's you mount it to the stock hood hinges and use the stock hood latch. That's the price (sorry no price yet) for the fiberglass hood with a Nomex honeycomb core (for strength) and no inner frame. Must be mounted using hood pins. That's the additional price over the cost of the CF/Nomex hood at top if you want an inner frame so you can mount the hood to the stock hood hinges and use the center hood latch. So, the cost would be 648 + 194 if you want the inner frame on you're race hood. That's the additional price for a layer of CF over the top of the fiberglass hood so you can have that bling bling look CF hood (which really isn't a CF hood, like most of the stuff you see on the street). So, the cost would be 360 + 115. That's the additional price for a CF/Nomex hood so you can see the CF. So the price would be 648 + 108 for a clear gelcoat CF/Nomex hood. The prices are high because these are real race parts that are strong, with honeycomb cores, and fit well. They are made one at a time and not shipped over from China, 3,000 to a container.

As Tim said, there's a lot more to the cost of a job then parts and materials. 1. City and county permits and the time it takes to make the drawings, submit then, go down to the city and argue, etc. 2. The contractor's overhead - insurnaces, facilities, equipment, administrative costs, marketing costs, etc. 3. Subcontractor management. 4. And the BIG one - customer costs (project changes, site access, neighbors, payment problems...)

Some cast steels are very weldable with the proper technique. There are four main types of cast steel: Grey Iron - very high carbon and some free graphite - weldable. White Iron - very high carbon with a cementite granular structure - not weldable. Nodular Iron - same as grey iron with magnesium or silicon added for ductility - weldable. Malleable Iron - reheated and processed (annealed) white iron - weldable. You exhaust manifold is most likely Nodular Iron. There are two ways to weld it: 1. Pre-heat to 600-1200F. 2. Stick weld it using an ECI or an ENI rod. TIG weld it using 308L filler. MIG weld it using ER70S-6 filler. 3. Skip weld using 1" beads and peen each weld with a sharp pointed hammer as the bead cools. 4. Maintain interpass temperature above 600F. 5. After welding the part must be cooled slowly (over an 8 hour period) to room temperature. Bury it in deep lime or dry sand, put it in an oven set at 500F, or fire up the grill. Another way: 1. No pre-heat. 2. Stick weld it using an ECI or an ENI rod. TIG weld it using 308L filler. MIG weld it using ER70S-6 filler. 3. Skip weld using 1" beads and peen each weld with a sharp pointed hammer as the bead cools. 4. Make sure the part doesn't get any hotter then 250F except immediately around the weld you just finished. Be prepared to stop welding for a 1/2 hour at a time to let the part cool.

I'm with Scottie - BS story.

Also look for late 1970s and early 1980s 810s and Maximas. Some have a 3.70 R180 rear diff and a few (very few) have a 3.90 R180 rear diff which works very well with the 5 speed swap. You'll also need to get some type of LSD for the R180 you install.

KYB GR2s have very soft comrpession damping and are easy to bottom out. I have a set on the stock ride height 77 810 and I have to watch out for big bumps, driveways, etc.

An R180 diff that has a LSD installed can handle 320hp and 270 ft. lbs. of toque. That's what I ran in my 240Z for a couple years without any problems. By sticking with the R180 you save 30 lbs and get better driver's side halfshaft angles.

I don't have an definitive weight numbers for the 260Z 2+2. My guess would be that it's about 150 lbs heavier then the 2 seater 260Z. Gutting the interior is a pretty drastic thing. It makes the car very noisy inside and I would only recommend it for a track only car. I sell CF/Nomex and Fibergalss hoods and hatches. You can see them here: http://www.betamotorsports.com/products/240BodyComposites.html

Tuning is what you do after slapping on the parts, mashing the pedal, and the car scares the poo out of you because it constantly does something totally unexpected.

Your goal is a 1:28.1xx at Willow Springs Big Track. My L6 powered 240Z does a 1:28.2xx...

There doesn't appear to be much of a weight difference between a race prepared L6 240Z and a race prepared SR20DET 260Z. My 1970 240Z with a NA L6 weighs in at 2260 with all steel body panels, bumper, and a full interior. Amir's SR20DET 260Z weighs in at 2163 with no interior, fiberglass hood, fiberglass front bumper, one seat, and no rear bumper. Adding a CF hood and rear hatch to my car gets the 240Z weight down to about the same as Amir's 260Z. Weight distribution is identical (48F/52R) with my L6 moved back and down. There might be, at most, a 100lb weight benefit from the SR20DET engine over a normally aspirated L6 in any of the 240/260/280Z chassis.

Car shows are about the cars. Aren't cars the award winners at car shows? Best in show is for the car, not the owner right? Regardless of who or how a car was built, it was voted Best in Show because the judges thought it was the best prepared and presented vehicle. If a car show want's to recognize the best homebuilt then it should have an award specifically for that. If the show wants to recognize the best builder then it should also have an award for that. I've had the privlidge of touching and seeing up close, inside, and underneath some phenominal vehicles prepared by Chip Foose that have won Best of Show at Oakland, Chicago, etc. Those cars deserved every award they won even though the vehicle owner (who paid millions!) didn't turn a wrench. I especially like the Grandmaster http://www.chipfoose.com

From Belmont Club... Saturday, July 17, 2004 The Man with No Name David Warren is all for naming a certain branch of Islam as the enemy. He argues that common journalistic and policy references to "Al Qaeda" have misidentified the true enemy. In the course of three years' intense study of the issue, I've become convinced that there is -- well, this is a slight exaggeration -- no such thing as "Al Qaeda" It is, more precisely, only a name applied vaguely to one of several financing and logistical arms of the Wahabi branch of what could more accurately be called the "Islamic Jihad". And the reason this is so important, he argues, is that it allows Homeland Security to use the appropriate kind of filter to root out the enemy. It recalls the scene played out in B-movie science fiction plots where the deadly aliens remain invisible until the sensors are tuned to the right frequency. And then they stand out plainly. This may sound a very abstract analysis, but it has practical consequences for "homeland security". For starters, it means we cannot draw neat, legalistic lines between who's in and who's out of the cabal. For instance, a journalist working for Al-Jazeera may be every bit as committed to the struggle as a man rehearsing the assembly of a mid-flight bomb. Each is advancing the Jihad by the means most available to him. And, exempting the one from prosecution while arresting the other is entirely obtuse. Indications especially from the FBI are to expect a major terrorist hit on North America, sometime between now and the U.S. election in November. I think they are right to expect this. The political, economic, and social fallout from such a hit is unpredictably huge. But I am less and less confident that it can be prevented by anything resembling normal police methods. This is because, thanks chiefly to "political correction", we cannot look at the whole Jihad, and are in fact only looking for the pointy bits. Warren argues that only by seeing the real enemy can we fight it. The idea of grappling with the unnameable threat also pervades the writing of Bat Y'eor who recently gave an address to French Senators. What, she asked, was the meaning of all the internal security preparation she had encountered. One need only look at our cities, airports, and streets, at the schools with their security guards, even the systems of public transportation, not to mention the embassies, and the synagogues – to see the whole astonishing array of police and security services. The fact that the authorities everywhere refuse to name the evil does not negate that evil. Yet we know perfectly well that we have been under threat for a long time; one has only to open one’s eyes and our authorities know it better than any of us, because it is they who have ordered these very security measures. ... Today the war is everywhere. And yet the European Union and the states which comprise it, have denied that war’s reality, right up to the terrorist attack in Madrid of March 11, 2004. Y'eor maintains that "today, Europe itself is living with this Great Fear" the source of which everyone knows but is afraid to mention in almost the same way that an earlier, more superstitious generation avoided mention of the Devil for fear of conjuring it. But the problem with conceding the point to David Warren and Bat Y'eor is that it merely articulating the word would cause a revolution in domestic and international politics something neither Democrats nor Republicans are prepared to do. Domestically it would mean that for the first time in American history, a major branch of a world religion would be declare a de facto enemy of the state. Not people, not a country; nothing with a capital unless it be Mecca, but a system of religious belief. It would strike at the very root of the American Constitutional system. Internationally it would signify that the principal enemy host, the Kingdom of Saudi Arabia, whose ruling house is intimately connected to and supports this ideology, should be targeted or its regime changed. Naming Wahabism as an enemy would indicate that the Iraq campaign, which the Bush administration was at pains to reach, was not the end but merely the beginning. One the most most striking things about the Global War on Terror is how closely it's resolution is linked with the longest standing issues of Western society. For that reason the war intrudes directly and insistently on Western domestic politics. The Madrid bombing of March 11, 2004 and the American Presidential elections in November are cases in point. Both are essentially about the War on Terror. The enemy cannot be named because doing so would overturn the 20th century political and economic foundations to its roots. It would tear down the Big Tent of political correctness; put a prosperity heavily dependent on oil supplies at risk; and replace an entire paradigm of international relations. For that reason naming the enemy will avoided for as long as possible; perhaps even after a mushroom or biological cloud darkens an American city. Nelson Ascher at Europundits describes how deeply ingrained the Western aversion to waging all out war is. He recalls how Israel of all countries set the standard for appeasement in the 1990s. Despite daily attacks by those who explicitly called for Israel's destruction; despite a memory of the holocaust; despite an intimate knowledge of the Middle East and the presence of a large number of native Arabic speakers who could read the enemies daily messages perfectly, Israel clung to the illusion that it could make peace with murderers until it was no longer possible to deny that they would have to fight if they wished to survive. In the 90s, not only the Israeli leadership, but much of the population nourished the idea that a definitive peace was well in the way to be achieved and, because of this faith, most newspapers and the media, whenever there was a terrorist attack, said that Israel wouldn’t give in to the terrorists who wanted to destroy the peace process. In other words, one of the requirements for peace was a toleration of the murdering of Jews, and far too many Israelis agreed with this. Quite simply, no country on Earth tried so hard to appease terror, to believe terror was not terror, to believe not only that peace with the terrorists was possible, but also that it was right around the corner as Israel did in the 90s. Shortly after the beginning of the current Intifada however, even the Israelis got fed up and thus, after having elected the politicians who were willing to satisfy almost every one of the Palestinians’ exigencies, they changed their minds and not only sent the appeasers to history’s dustbin, but also elected and then re-elected the country’s principal hardliner, a man whose very name had been taboo for many years: Arik Sharon. Why did they elect Sharon? Because they discovered that, more than inevitable, the conflict with the Palestinians and much of the Arab-Muslim world had never ceased, had never gone away. Anyone who wanted peace got to the conclusion that there wouldn’t be peace before or without victory. The public awareness of the threat to America despite September 11 is many orders of magnitude less than Israel's. America's immense size, wealth and power provide it with the illusion of invincibility that was never available to the Jews. Consequently its road of appeasement will be much longer; its Michael Moores more numerous and its final awakening more tragic. The Israeli experience shows the end of appeasement is inevitable. But for the present many will regard national security as a game whose rules are to be flouted. Something profoundly uncool. The loss of hard drives containing classified information at a premier nuclear weapons lab shows how few people inhabit the world of David Warren and Bat Y'eor. For the third time in five years, Los Alamos National Laboratory is shutting down all classified work and hunkering down for investigations and political lashings over the loss of two disks of nuclear-weapons related secrets. ... "I don't like the culture at Los Alamos," said UC vice president for lab management Robert Foley. "I've said it before and I'll say it again: I don't like the culture." "There is talk going around Congress of having legislation that will forbid the University of California from bidding on (the lab) contract because of this incident," (Los Alamos director) Nanos told lab employees. "People in Washington just don't understand how any group of people who purport to be so intelligent can be so inept." Some critics of security at the nation's weapons complex say the Energy Department should get rid of the university as Los Alamos' manager immediately. "I don't think UC should be given any more chances," said Danielle Brian, executive director of the watchdog group, the Project on Government Oversight. "I don't see how they can redeem themselves any more. It's become laughable." If it is laughable, then it is dark laughter. What was on those disks? "Think about this," Nanos told reporters, "If you were to tell everybody in the world that this information is out there, you might start a treasure hunt." And that 'everybody' includes the men with no name. http://belmontclub.blogspot.com/

Sounds like you have a bunch of caster. That's a good thing from a handling point if view (up to 6 degrees positive). I had to cut the back edges of my front spoiler when I ran 275/45-16s on my car.

You can also add this setup to the list. Its mostly EMI Racing parts: http://www.betamotorsports.com/products/240StrutKit.html Most of the stuff for 240Zs have been around for 20+ years. Its all well sorted out and works. Just because a part is JDM doens't mean its good or it works.

Not always true. I witnessed something exactly like this and stopped. From my statements the cop wrote up the person who slammed on the brakes for an unsafe lane change and reckless driving.

Here's my best story so far... Two lanes merge into one lane and there's a lot of traffic moving at about 40 mph. Everyone's merging politely, every other car into the lane that continues. That's until a white Neon comes up to my front quarter after I let another car merge and tries to squeeze in front of my truck. I just keep my pace and don't leave any room, the car behind me has backed off and left room for the Neon to fit right it. The Neon is now next to me and I see a perfectly manicured and polished middle finger stuck out the window at me and she tries to pull ahead of me again. The guardrail convinced her otherwise and she finally pulled in behind my truck, flashing her lights and honking her horn. I thought nothing more of it until I got to my shop. There was a message on my message machine (I have my shop logo and phone number on my truck). The message is from a very irate woman named Eileen who claims one of betamotorsports employees almost ran her off the road and she's going to sue the company. She also left her phone number. I immediately called her back: Eileen: "Hello." John: "Hi Eileen, this is John from betamotorsports and I understand you ahd a problem on the road with one of our trucks." E: "You're damn right I did, that motherf***** almost ran me and my daughter into a guardrail. I'm going to sue you for everything you got. Someone's going to jail. You just don't do that to poeple..." and on it went fo a couple minutes. J: "I'm sorry to hear that and I apologize. When and where did that incident occur?" E: "About noon on Carbon Canyon road. You know, I think I might have heart problems as a result..." and on it went again for another couple minutes. J: "Again, I'm sorry that happened to you and your daughter. Chris was driving the truck at that time and he's been going through a lot of trouble in his life, what with his wife committing suicide last year and his daughter being diagnosed with Melanoma, but that's no excuse for that kind of behavior. This has happened before and as a responsible business owner I can't have my employees risking the public's life in our trucks. I guess I'll have to let him go. I appreciate your call and thank you for pointing out this problem to me." E: "You're going to fire the guy?" J: "Yes, I'm afraid so. I can't risk my business. He's worked here for 15 years and absolutely loves it. Last year after his wife hung herself in the bathroom he said working here at betamotorsports was the only thing keeping him going. Its a shame but I have my business to think about." E: "Wait. What happened really wasn't that bad. We didn't get close to the guardrail and I guess I was just venting some emotions when I said I was going to sue." J: "No, you were really scared and I can't have that. I'll let Crhis go this evening when he gets back to the shop." E: "No please. Most it was my fault anyway because I was in a hurry. Please, just let it go. Maybe just have a talk with Chris." J: "Thank you for your concern, but I after what you said earlier I'm going to have to fire Chris. Too bad, he was all set for a big raise next week to help pay for his daughter's treatment." E: "Please, don't fire him, forget I called. He's go too much in his life right now and I have a daughter too. It was all my fault and I acted like an a**." J: "I appreciate your concern but I've made up my mind. Thanks for your call and have a good day." I hung up the phone. She called back a couple times and left messages but I ignored her. BTW... I don't have an employee named Chris.

Keep trying the search function. This topic has been covered thousands of times in the Drivetrain forum. A quick search by me using R180 R200 and Swap and selecting the All Terms option came up with at least a dozen threads specific to your questions. Make sure you're using the underlined Search with the little magnifying glass icon.

Over the years I've lost some of the old electronic images of my car. They got stored on Picturetrail and some of the other picture hosting vendors that went belly up. I'm going to start on a roll bar on a 240Z in a couple weeks and I'll be sure to take a lot of pictures then. Another good resource for cage information is Keith Thomas' (katman) old ITS cage article. Do a search here on HybridZ because I think he scanned the pages and posted a link somewhere.

I would love to bring that thing to the next Ferrari Club event!

Never tried British LSD...

Regarding Quaife's I've yet to wear one out (I have two) and have been running one since 1998. No internal adjustments except for preload. Heat is also generated because of work. The work is the gears doing their job and generating shear loads in the diff fluid. True for the first part and the wheel coming off the ground is a suspension tuning issue, not a Quaife problem. If you're lifting the inside rear wheel off the ground you will tend to break stub axles regardless of the type of LSD> The unit didnt' slip. It went open way too easily. Some of that was suspension tuning on my 240 and some was a preload issue with the Quaife. Quaife didn't fix it because they said nothing was wrong with the unit. Taylor Race Engineering slightly modified the unit for my applicaiton by increasing the preload. Also, softening the rear roll rate helped eliminate the problem. Haven't heard of a Quaife failing yet. Heat can be created from friction and from work. The Quaife generates its heat from work, not friction. The shear loads on the diff fluid are very high and that's what creates the heat. The big "issue" with the Quaife is that you have to tune your car's suspension to take full advantage of it. The rear roll rate needs to be softened to keep the rear planted. This affects how the car handles and how you drive the car. A typical west coast Z is setup neutral to slightly oversteering with a pretty stiff rear roll rate. This allows the car to fly into corners and carry speed through mid corner. But, it affects corner exit and puttung the power down. With a Quaife until the car should be setup to be neutral to understeering and the car enters corners slower but man, you can just plant your foot (even with 300+ hp like my car) once you're pointed at the apex. That's a typical east cost Z setup. FYI... I just called Terry at Taylor Race and the retail price for the R180 115mm ID Quaife ATB is $1,445, which is $150 more then the original 1998 retail price of $1,295. Unfortunately, they are NLA until Quaife gets another group order of 25 or more.
