http://hybridz.org/nuke/index.php?name=PNphpBB2&file=viewtopic&t=31206 When those videos were taken I had 8.5:1 and .490/280 cam, triples, and 2.5" exhaust. Ran pretty good. Runs better with the new flat top piston bottom end...

Tightening up the steering on a worn 240z?
JMortensen replied to Hugh's topic in Brakes, Wheels, Suspension and Chassis
It's a safe bet to replace ball joints and outer tie rod ends on just about any Z you pick up. Control arm bushings, TC bushings (do a search on this one), and maybe steering coupler would be next. You can check all of those components for play individually so you don't buy anything you don't need to, but ball joints and tie rod ends would be my first stop if I were you. -
I saw the ...... after I replied, sorry about that. I understand what you are saying but if I had 5,000,000,000,000 gallons of lamp oil I wouldn't be shopping for candles, if you know what I mean...

I'm well into the stitch welding prep right now. What a bitch!!! Anyhow I stripped off all the rubber sound deadener on the rear deck yesterday (air chisel pops it right off, just need to clean the residue off). When I got the rubber off and it looks like the early 240s have a single piece of sheet metal that lays flat where the later Z's have the compartments. This piece is spot welded to the deck just forward of the strut towers, and it has a little lip that is spot welded to the vertical piece behind the seats. My plan is to stitch the seam in front of the strut towers, and also where it hits the vertical piece, and also along the sides if possible. Warning to anyone wanting to do this: It's a bigger job than it looks. And I was pulling off some BEAUTIFUL welds on my struts and crossmember, etc. Welding this sheet metal is humbling... Questions: 1. I've seen people weld up the 4 big rectangular holes in the vertical panel behind the seats. Am I correct in thinking that there is a bit of stiffness to be gained there? 2. The swiss cheese holes in the deck... I wouldn't think that they are a problem. I was planning on not worrying about them. Good idea? Should something be done about that area?

Why would any OPEC country need an outside source of energy for power production??? Come on Pop think about it. These guys could burn any number of petroleum products and produce energy without having to stir the shit. It seems clear to me that they want to be the big bad Islamic theocracy with a missile. I think Israel will take unilateral action, and I think if I were Israeli I'd be wanting to take unilateral action. Whether they can defuse the situation alone remains to be seen.

With coilovers done right and rolled fenders I think a 9" rim will fit. I haven't tried myself, but with my 8's and the amount of space, that's my best estimate. That puts you somewhere in the 245 to 265 low pro tire. I would use closer to the 245 myself, but I'm more concerned with handling than going fast in a straight line.
-
Yeah, it will FIT on the rim. Sure. But it won't WORK very well on an 8" rim. Take it from a guy who is running a 250/45/15 slick on an 8" rim and wishing he had 9" or 9.5" rims. Then again, if you like that balloon tire look and don't really care about the handling, then it will fit... EDIT--Drag slicks are MUCH different than low pro street tires. The sidewall of that low pro is going to be stiff, which is where the problem comes in.

Looks like the cowl is now attached to the A pillar though... I agree though, it LOOKS nice.

http://www.modernracer.com/hondacivicsi2002.html Curb of 2744, add 150+ lbs of stereo say 180 lbs for driver, 3050 or so. I was thinking that Mike was WAY off base, but turns out you're pretty damn close... One more reason to laugh at Honda morons...

Did you make any $$$ selling the extra Mat? I hope you did. I know I bought a set of spacers...

Comments??? Shot across the bow??? The Mossad just assassinated a Hamas leader in Damascus. http://story.news.yahoo.com/news?tmpl=story&cid=540&ncid=736&e=9&u=/ap/20040928/ap_on_re_mi_ea/syria_palestinians I don't know what to think on this one. On the one hand they could attack and hope for a Spanish style response, but they have to know better by now. You know the last thing they want is another 4 years of Bush. It's a tough one. We'll see...

Modern Motorsports vs. Arizona Z car?
JMortensen replied to Floorless240z's topic in Brakes, Wheels, Suspension and Chassis
Not so sure on this one. I think it will extend the SERVICE INTERVAL by a huge amount, but not the life of the caliper. The only thing moving in the calipers is the pistons past the seals. You can buy new pistons and new seals for the Wilwoods. What else is going to wear out??? The main reason I resisted Wilwoods for so long was the lack of dust seals, and the fact that I drive my car on the street. Having suffered from no brake pedal on a number of occasions now, I wanted to avoid any potential leaks. But it really boils down to how you change the pads AFAIK. When you change pads on Wilwoods, I've heard 2 approaches: 1. Disassemble the caliper, change all the seals, inspect the pistons for scratches, and reassemble. 2. Push the pistons out farther, clean the pistons as much as possible, then push them back in and hope that they don't leak. I've also heard people say it doesn't matter and that you just push the pistons in normally and it won't cause a leak. As far as downsides to the PBRs the main one is COST. They seem to be touted as at least as rigid as Wilwoods (which surprised me) and they are lightweight, although I don't have exact weights to compare. -
I just assumed he'd be going to an L28 bottom end. Dan's right, there isn't really any point to working on an L26, unless it's just to keep it running while you source an L28.

Do a search here and you'll find some less outstanding reviews on the Phantom Grip. It is going to work for a while, no doubt about it. The longer you use it, the less it works. Change the gear oil and theres a whole lot of metal in it. That crap is running through your bearings, and being shoved between the ring and pinion. I don't know that anyone has checked diff fluid temp while running a PG, but I bet it is SKY HIGH. But here's my real problem: If you set the spring pressure really high so that it doesn't spin a tire coming out of a corner hard on the gas, then it is going to cause a lot more push when you're trying to get INTO that same corner, and is also going to be really really tight just driving around town. If you set it nice for driving around town, then it is going to slip coming out of that corner. Again just about every other LSD available including the Nissan clutch style, the Torsen, the Quaiffe, etc all "sense torque." The harder you push, the more it locks up. Look at posts in the drivetrain forum where people who have broken their diff. I've seen one common problem. The cross pin shaft wallows it's hole in the case. There is only one cross pin in the 2 pinion open diffs, and there are 2 pins taking the load in the 4 pinion posis. So these inserts don't fix the major area of weakness in the R200.
-
What Doug said will work but I would expect that you'd be really lucky if those gears weren't noisy. The ring and pinion do wear into one another. Here is another attempt at an explanation of ring gear bolt spacers: The bolt size is the only real difference between the old R200 and the newer R200 (not dealing with the short nose, just the long nose here). So you can use the 12mm ring gear with 10mm bolts. The bolts should be snug in the ring gear, and obviously there is going to me a 1mm gap all the way around the bolt. So you get a 1mm wall thickness tube that is 12mm Outside Diameter and 10mm Inside Diameter. Cut the tube into 10 pieces that are as thick as the carrier, deburr them and drop them in. Now you can use your 10mm bolts, and they are snug in the carrier. Here is another thread dealing with this issue:http://hybridz.org/nuke/index.php?name=PNphpBB2&file=viewtopic&t=32641&postdays=0&postorder=asc&start=20

So are you going to tell everyone who the "bankers" are Kevin? A close look at his post of the bankers' names should tell anyone who they are. What does your conspiracy theory say that we should "do" about them Kevin? How much of your conspiracy theory do you believe, and how far towards the ugly and evil end of that theory do you go?
-
I think it probably is. It basically works just like a Phantom Grip, but has some Kevlar where the blocks meet the side gears. Relies on the spring pressure between the blocks to limit the slip, and does not "sense torque" like the Nissan Clutch style and the gear driven styles. Also still relies on the 2 pinion setup, which is the weak link in the R200.

Shave the P79 .080 and install the N42 valves and shim the cam towers .080 and the cam geometry and all that should stay correct. Your machinist should be able to get cam tower shims for you. Don't worry about the exhaust liners, they're not much if any hindrance until you really start porting the head a lot. The N42 can just be slapped on, but some have experienced pinging with that combo. Both the E31 and the N42 have lots of sharp edges in the chambers which can cause pinging, where the P90 uses a much better casting AND has a much larger quench area which should provide a significant advantage. Neither the E31 nor the N42 is the best head from the factory IMO, and you'll spend probably 3x more in machine work to install larger seats in the E31 then you will to shave the P79. That P79 should theoretically get you to ~9.6:1 with a bone stock flat top L28 bottom end. The N42 gets 9.8, and the E31 gets 10.2. These numbers assume that the head hasn't been shaved before you got ahold of it. We just had a LONG and surprisingly bitter argument about this, search the 6 cylinder archives for a post that started with Newbie. Should still be on the first page of the 6 cyl forum. Look here for more info on shaving the head: http://www.geocities.com/zgarage2001/head.html

I didn't think I was going to like the sales tax, but it actually looks pretty good to me. A few issues I can see: 1. Poor people have to pay the tax up front and won't get it back until the end of the year. 2. People could conceivably make large purchases in Canada or Mexico and avoid taxation altogether. If I took a day trip to Canada and bought $25,000 worth of electronics as an example the sales tax system would rely on the honor system for me to declare it to the customs people at the border. I don't see an easy way to force people to state what they've purchased in another country. "No Mr. Customs Officer, I just thought I'd take the home entertainment system on a day trip to Canada..." 3. Doesn't affect state law, so only takes away 1/2 the accounting headache that the site states costs $150 billion per year. 4. CPAs aren't going to be very happy that nobody needs their services anymore. Maybe they can transition to investment analysts and help us invest some of the money we save. 5. That site says that the tax rate could be lowered as the government gets smaller. If the govt has more revenue, it's been my experience that govt only gets bigger. 6. International mail order is nearly impossible to regulate, and although getting more tax revenue would be a great way to give the govt an incentive to monitor what comes into the country (I'm thinking Homeland Security) it would still be an expensive proposition, but IMO worth it. 7. A large percentage of the tax revenue that could be had from immigrants who send most of their check to another country would be lost. You could argue that these people aren't usually the very high dollar earners now, but they very well could be if this law passed. Executives could start coming to the US and sending their earnings elsewhere. If these issues were dealt with in the article, forgive me. I read it while working so I might have missed something.

You could get a 12mm unit from differentials.com and some 12mm OD 10mm ID tubing from a metal supply place (there are a bunch online)and make ring gear spacers. Just cut, chamfer, and drop them in.

tkach, if you're going to post that you don't like when people who haven't been to Iraq talk about Iraq, then people are just going to tell you not to look at the discussion. This is the internet, and you don't have to read anything you don't like. Also if you write whatever you're going to post in Microsoft Word it will show you where your spelling errors are. You've got a lot and it makes you look less intelligent when you post something full of errors. Also, I agree with you that we need to stay until we've won the peace, but I haven't been there. Does that mean that my opinion doesn't count?

When I read this sentence all I could think of was an argument I've heard about South Africa. Here's my switched around version of the same sentence: Again we hear a "why didn't we go into x first?" argument. Well again I would guess that you wouldn't be too happy if we did go into Sri Lanka either.

Do you REALLY believe that swearing to tell the truth guarantees that a witness tells the truth? Bush set up the commission? News to me. I know he authorized it, and I would agree that he did so reluctantly. I could be totally off base, but I don't think he had all that much determination as to how it worked, etc. Maybe his testimony is full of stuff that we shouldn't have access to. And demonized by just about every major newspaper and newscast. Really? What logical steps are you using to determine that anyone who doesn't want to tell YOU everything they know about a subject is lying? I'm sure Mike Kelly has an opinion. I'm sure he won't divulge every detail that he knows about the subject. I'm not sure that this makes him a liar...
-
Couple of things: First, we already KNOW that lying under oath is not an impeachable offense. Second, everything that I can find says they TESTIFIED to the 9/11 Commission, just not publicly. Third, I think you could make a better case for dereliction of duty for a president LYING to the Commission than you could for one perjuring himself as in the Lewinsky scandal. Most importantly though, if the Democrats in the Commission who questioned them had only good things to say about their testimony, then why are you taking issue with it? Maybe because it's not public info, and maybe that's where we disagree. I don't think everything that the govt does should be public, and I understood why Clinton and Bush did their testimony in private.
-
Phil, you need to start reading the newspaper or watching the news or something. Bush and Cheney answered questions for the 9/11 Comission together (I want to say for 8 hours, but that's from memory so might be a little shaky), they just didn't do it publicly. I don't blame them. The Comission even released a statement thanking them for being so forthright afterwards. Did you watch any of the hearings on CSPAN? I watched them interview Condoleeza Rice (sp?) and let's just say that they weren't fair and impartial. Clinton didn't testify publicly either. Is he a bad guy too for not doing it publicly.
