Are you short shifting? Tach verification Tech Info
JMortensen replied to a topic in 6 Cylinder Z Forums
I verified mine by putting a 6800 rpm pill in my 6AL and hitting it. My autometer shows 6800 rpm at the rev limiter. Plus it's just one wire from the MSD to the tach. A friend of mine FREAKED OUT when I drove her Z and wound it up to ~7K. Apparently her tach was showing 8500 or something. I was unable to convince her that her tach was wrong, until I asked why her valves hadn't floated if it was really at 8500 rpm (stock springs, mild cam). She still hasn't fixed it. I've never had good luck with ANY of the stock gauges. Tachs are innacurate, speedos jump, temp gauges are CRAP, oil pressure gauges are a just so vague that they're useless, I've been thru several ammeters, and the gas gauge looses 1/2 tank in the first 1/4 tank but I think that is the shape of the tank more than anything else. I've only seen one working clock ever, if you want to count that as a gauge. I agree with Lockjaw, just replace if you want to really know what's going on. Jon -
What will make used rims work with ZG flares

Different wheels... Jon -

JMortensen replied to a topic in Brakes, Wheels, Suspension and Chassis
I am assuming that these wheels fit under stock fenders, BTW. If they stick out of stock fenders and you need 1/2" spacer, and you are willing to change studs, then go for it. Jon -
What will make used rims work with ZG flares
JMortensen replied to a topic in Brakes, Wheels, Suspension and Chassis
Even so, a 2.5 inch spacer, then the thickness of the wheel flange, then your lug nuts?!?!? Is this a good idea??? Sure, when I worked on Porsches we used 2" spacers, but we had 5 14mm ARP studs on there... Jon -

JMortensen replied to a topic in Brakes, Wheels, Suspension and Chassis
Aren't the ZG flares like 2.5" in front and 3.5" in back? If so, that is one heck of a spacer. I'd look for different wheels. I've seen a couple of posts about this in the last few weeks. While this might be possible with some really long studs, you still need some threads in the lug nuts, which makes me think that different wheels would be a better alternative. Or is there something I'm missing? Jon -
Chap, I think it's funny that every time a political topic comes up you think the other side is taking advantage of the situation... but wait... you were right on the restriction of freedoms/Patriot Act thing. The US needs more libertarians and less hypocrites. Jon

The assumption that minorities NEED help is the issue that Nic talked about, rather than their statistical disadvantage. The fact that we separate them from the rest of society and say that they aren't capable of making it without help is the problem. It can lead people who are minorities into a "poor me" mindset where they think that they CAN'T make it without help from whitey, which just isn't the case. I've known several self made millionaires, all of which came from DIRT, none of which got a scholarship based on their skin color or religion. They just never gave up. EDIT--I put words in Nic's mouth. He WAS talking about the statistical disadvantage. Jon

Will the diff from a 93 300ZX fit in a 74z?
JMortensen replied to Workinprogress's topic in Drivetrain
http://www.hybridz.org/phpBB2/viewtopic.php?t=30930 It's in there (the drivetrain forum). I don't mean to come off like a jerk, but since the search function isn't working for about a week, you just gotta dig through the forums a little. Sorry if I offended, but it's obvious from your 1st post that you are going to have a LOT of questions. Nothing wrong with that at all, just trying to help you get them answered. Jon -

Read through the forums before you post any more questions. I answered this in your other post. Jon -
What parts are compatable???
JMortensen replied to Workinprogress's topic in Brakes, Wheels, Suspension and Chassis
Normally the response to both of your posts would be "Use the search function" but it is not working until they switch the whole site to the new format. Tim240z has just posted some stuff on diffs. Search the drivetrain forum. He used an R230 (230mm ring gear) which is a 9" ring gear. As to your previous front suspension question, you can get bigger brakes, better strut inserts, coilover spring kits for adjusting height, camber plates, custom control arms, and custom TC rods, but they usually aren't sold as a kit. Closest I've seen is http://www.arizonazcar.com, and their stuff is pretty pricey. Search the suspension forum for more stuff on that. Just dig a little, you should find lots of info. Jon -
California Peoples, need your opinion on weekend trip.
JMortensen replied to Sparky's topic in Non Tech Board
You could go camping at Lime Kiln. Just try and get a reservation now, because they are usually booked. Also, if you want to spend a couple hundred bucks, there is NOTHING better on the planet IMO than a weekend at Sycamore Mineral Springs in Avila Beach. It's so romantic you'll never leave the room, if you know what I mean. I used to go there every Valentine's Day with my wife, some wine, cheese and chocolate. Good times. 8) If you want to go snowboarding in March, you'll probably need some pretty good elevation like Tahoe. Jon -
There is a manual adjust slave cylinder, and a self adjusting slave. IIRC, the self adjusting slave and manual slave are the same thing internally, the only difference is the manual slave has a spring between the slave and the throwout fork to return the slave, and the pin with the adjuster nuts that sticks out of the slave. Also, the fork has a hole drilled in it to allow the pin to stick thru the end of the fork, so that the part that you adjust is the part that pushes on the fork, not the end of the pin. It's been a while, but I am pretty confident the above stuff is correct. So a manual slave and fork may allow you more adjustment, not sure if you could get the correct adjustment if you changed the collar or not. You'd have to find someone running all the same components as you've got, who has it working properly. Jon

You guys would LOVE a book I read a few years back. Liberal Racism. Can't remember the author, but it was a good read. BTW the author was a democrat and didn't think that conservatives had it right either. Jon

The air hammer works really really well. Very easy job with the right tool. Using a slide hammer is tough, and using a hammer on the back side can mushroom the end of the stub axle. Jon

Just Showing Off My Car Finally (warning Dialup)
JMortensen replied to Datsun660z's topic in Non Tech Board
I gotta get off of this forum... it makes me want a V8!!! Good looking car, and I envy your hp. I would ditch the bumpers. Jon -
I am 99% sure the CV shafts have the side flanges built in. It should be obvious when you pull them from the ZXT. Jon
-
RossC has an adapter for those CV's I think if you have the $$$ for them. If you don't run the CV's you'll need some side output flanges from a 280Z or ZX with an R200, and you'll definitely need the pinion flange or yoke from a Z or ZX with R200 to bolt up to the driveshaft. Use regular gear oil with an LSD additive, or better gear oil without the additive like SWEPCO or Redline or something like that. I use SWEPCO. Works great. Jon
-
I could build my car again and save at least 8-10K. I may not have a V8, but I wish I knew then what I know now... Jon

FOOLS Street racing... Jamie T, Did you know these guys???
JMortensen replied to Mikelly's topic in Non Tech Board
Yeah, I kept telling him it wasn't fast, and he kept doing huge burnouts trying to convince me it was... moron... It was a stock '88 I think 5.0 Convertible with a 5 speed, BTW. Jon -
Have any of you guys messed with a Motec? I tried to help adjust one about 5 years ago, and hopefully they've gotten more user friendly, but back then they SUCKED! We had a guy who was a race mechanic, then went into IT, and HE couldn't get it right. I was watching what they were doing, but I could barely understand what parameters they were messing with at the time. I ended up being no help at all. I like the idea of SDS for those of us who are technically inept, Motec is fine if you're an EE or IT major with a minor in racing EDIT--Now I think I remember it being something other than Motec. It was used in F1, maybe a Zytech??? It's definitely not a home equity loan though... Jon

OMFG!!! Sounds like an F1 car! Wonder what kind of tranny can handle those shifts!!! Jon

FOOLS Street racing... Jamie T, Did you know these guys???
JMortensen replied to Mikelly's topic in Non Tech Board
I'm sure it was just a street racing accident. F'ers. This guy I used to work with didn't show up for work one day, turns out at the end of the long wide boulevard we were on he had smacked the center divider in his Mustang, while racing a SE-R Sentra. Most people just don't know how to drive and they don't think street racing, especially on a blvd that is wide and straight and has a center divider is dangerous. Well it is. Some pickup had dropped a 2x4 into the road, and the Sentra swerved to miss it at 100+, got a little sideways, and took out himself and the Stang. There is always some rationalization as to why it is safe in this particular instance, but people are just fooling themselves. Luckily no one was seriously injured like in this case, but these are all just reinforcements of my "take it to the track" motto. Not that racing at the track isn't dangerous... Jon -
Also, if you pause the vid right after I catch the slide you can see my 2 black streaks from flooring it during the slide. 8) Jon

Apparently you didn't hear the engine revving! I floored it asap, but the Mikunis pump nozzles that were way too small at that time, so it didn't do much for a second or two. The extra pressure in the rears really made the tail happy aspect worse, the car normally doesn't act like that. It makes for good video though!!! I'd like to see what your car can do. I would venture a guess to say that you are probably a bit faster than me, I still had a full interior, insert several other excuses here... Jon

YEP. Thanks! Jon
