There's a guy on the wolf web with an Integra Type R (basically a track car) who said he's interested in running the 20B FD on the track if possible.

Ahhh, I work wayyy too much. I think that my mom and I have finally gotten the cell phone bill stuff straightened out. So now that means only one more huge bill, then we're clear. As for my car, it's still outta commission, but I can finally move towards purchasing a clutch kit next week, and seeing about how much to install it.

Just wanted to let everyone know that I'm still alive. Just struggling with the whole money issue. I can't wait till I can get evaluated and a raise and start making the bonus money. They're throwing around that I'll be promoted next year, and it's a decent jump of money for the position. I can't wait. But I missed not being able to go to the meet again. I'm going to the next one regardless of w/e I'm driving, whether it's my grandpa's '85 Dodge Ram 50, or a bicycle.

Just so we don't have a bunch of HP Junkies show up wanting to race Bryan's FD he is bring it to show and talk about. I am sure he'd like to show us what it can do, but primarily it'll be a show and tell. We'll know more when he lets me know what dates are good for him.

Everyone remember the Rotary Rendezvous at the Zoo this coming Sunday.

You still have the FB you can bring to the drive-ins right? You can attend the MSCCofNC meets over in RTP with no fear of ridicule now that you go both ways!:0) Please don't put any fake shark teeth in the front intake and don't ride with another guy.

capn

Bert please do tell when the 20B is coming, i will come down for the soul purpose of seeing that.

JKM

Yes, there is always the FB. Heh heh. But... I have to show up in the Miata just once, and I should bring my camera to take a picture of the "what the hell?"'s.

By the way, it's officially mine now. Got the title transfered and tags today.

WannabeFC

You know I gotta see some pictures of my car's replacement....

Christina, that must have been some other car you saw tonight. I didn't stop at any gas stations.

everyone vote 10 for that pic and lets get a rotor on a bottle of soda can someone put this on the rx8 fourm?

JKM

I can do that, I just need to get another battery for my camera, I killed it taking pictures of your car. Oops.

Somehow, I think you'll be thinking "He traded that FC for THIS?"

GTUser

I will add comment to the appropriate monthly DI thread and will post here and also create a special thread for that occasion. I might sent you a PM to personal invite you to the showing. Might get you off this Northstar transplant thing. Or will you suggest to Bryan how much better his FD would run with a NorthStar transplant?

PerkyStina

I dunno... it was a white S4... and looked pretty frickin shiny. Who else has a white one?? They were gone by the time I got the car running again. (My battery went bad yesterday, so I had to get a new one.)

capn

well bert, if 20Bs were as common as Northstars then yes i would do that. or if you can find me a 20B for a good deal the northstar motor will get the swan song.

iTrader: (1)

a 20b conversion will cost you at least 10k by the time its all done with. How much are you planning on spending on your northstar conversion?

WannabeFC, you go to State right? Do you park in the west lot? I just left a note on a red S5 FC. I realized later that it could be your car.

capn

prolly just as much

PerkyStina

Well I got a new battery, and just installed it... and the car still wouldn't start. Probably a bad starter. Fabulous. I don't have ANY money to get a new starter.

I don't have a car to go to school or work, so now this week is hell. I wasn't taking the RX-7 to the zoo Sunday, anyway... but damn. *SO mad!*

Anyway, that's it... I'm going to start looking for a 240sx or some other more RELIABLE daily driver. I need a second car BAD. Ugh. I have now decided that an N/A Rotary is useless. It's too slow, so I can't race it, and too unreliable to be a daily driver. Gayness.

My RX-7 SUCKS.

Hey guys heres the second college paper and its on what else? ROTARIES!!! so please i would like some input and some crituqing(sp) of it for accuracy and such.

Quote:

When most people of automotive nature hear the word rotary motor most of them cringe with thoughts of horror stories concerning the engine. This is not uncommon; for the most part people that don’t know much about the rotary motor, and with most alien concepts, tend to look down on them. The rotary motor is much simpler and easier to work on then most think; it has less moving parts and thus fewer things to go wrong. But when things do go wrong with rotary motors they go wrong in a big way. That why when things do go wrong, it’s good to know the process for fixing these simple engines, and the proper way to do so. To know more about the motor a person must first understand the main parts that go into the rotary motor. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

The rotary motor is far simpler then any piston engine to date; the rotary motor has only 3 main moving parts where as the simplest piston motor has about 40. Those three main parts are two rotors (comparable to pistons) and one eccentric shaft (comparable to a crankshaft). But the reason for the engine being so simple is that there are no angular changes of motion, the rotary motor just spins in one continuous direction with no linear movement to be changed to rotational motion. The best way to explain the motion of the rotary motor is like a Spiro graph triangle inside of a trochoid housing, think of a dorito spinning around in a peanut. Most people think that since this motor is so much better why isn’t it in all the cars today? Well the simple fact is its still in its infancy compared to the piston engine. The piston engine has been around for more then 100 years and been in testing for over 100 years. The rotary motor on the other hand was first conceptualized in the 1950s and not even put into a working model until the mid 1960s, so the rotary motor has come along way for just 50 years of being in production.<o:p></o:p>

The downfall of the rotary motor comes with its inherent simplicity, with so few moving parts those parts are more prone to damage than anything else. The main parts that become damaged are the rotors and actual housing, which the rotors are held in. They become damaged when one of the metal sealing bars, called an apex seal, breaks and scrapes all around this fragile aluminum housing and causes a big mess. Yet some people are lucky enough to where this seal breaks off and is projected out the exhaust without much damage to any part. Also the rotary engine is very susceptible to heat damage, if this engine overheats it will actually warp and distort the surfaces on which the rotor seals on and causing a substantial amount of compression loss. Heat may not only distort the surfaces on which the rotor mates, but it may also crack this mating surface and allow a coolant leak, which is very bad. <o:p></o:p>

Luckily most home garages equipped with basic hand tools can rebuild a rotary motor, considering they have a few specialized tools. First they need a massive two and one eighth socket to secure the large flywheel nut. Next you need a nice torque wrench to properly tighten the tension bolts which helps hold the sandwich of a motor together. You also need specialized measuring tools such as the feeler gauge to check for proper clearances and then a dial indicator to check proper endplay. Other then having a good set of metric wrenches and sockets, and the specialized tools a home mechanic can complete this project in about three to five hours depending on how meticulous they are about detail.<o:p></o:p>

The actual assembly of then engine is pretty straight forward, before the assembly takes place one must disassemble and clean all reusable parts of the engine but for the sake of time we will assume that all our parts are within the allowed specified range and are clean and reusable. The first step in assembling the engine takes place with bolting on the front stationary gear to the front iron plate and tightening the six bolts to the proper torque, the iron plates also have coolant seals to help seal the combustion chamber from coolant. Next step is placing the aluminum rotor housing on the iron plate making sure to have the dowel pin lined up to assure proper mounting. Next step is taking a rotor (with all the appropriate seals and rings in place) and placing it so the gear side of the rotor meshes with the front stationary gear to form the desired Spiro graph effect. After the rotor is in place the eccentric shaft can then be lowered in the middle of the rotor. Once this is done you can place the intermediate iron plate (with coolant seals attached) down on the rotor and rotor housing, still making sure the dowel pins line up for a proper fit. The following steps are basically the same as before except that this time the completed rotor is lowered down on the eccentric shaft with the gear facing up. The rotational placement of the second rotor is irrelevant because when you lower it down on the eccentric shaft the rotor will line up in the right direction eliminating any guesswork and possible areas of error. The last step is to bolt the rear stationary gear to the rear iron plate, with the gear in place and coolant seals attached to the plate it can then be lowered down on the assembly still making sure to have the dowel pins line up. And then after all this is done make sure all the sections are firmly mated together, once you are sure of this you can then place all the long tension bolts in the proper holes and tighten them in a criss-cross pattern to insure a straight alignment of the motor sandwich. This wraps up the basic assembly of a short block rotary motor, and gives a general outline to do so.<o:p></o:p>

Now some may ask, why go through all this trouble of doing it myself when I can just buy a new one? Most people debate this situation because of experience and cost. Cost being vastly different of the two ranges, a brand new rotary motor can cost upwards of two thousand dollars! Yet, if someone were to attempt this on their own they would be spending near five hundred dollars considering their motor was relatively undamaged. Although rebuilding may not be an option because of the extreme damage someone’s motor may have suffered or the lack of experience someone possesses. Rebuilding an engine yourself does not just offer a significant cost savings but also provides you with a new experience.

WannabeFC

Yeah, thats mine... I was wondering why somebody on here wrote that, knowing that I am on here allready...

You getting power to the car at all? Check your battery terminals and make sure they aren't corroded.

1RX7DRIVER

240sx isnt the cake its made out to be not even with the sr20det in it i sold one on ebay for a buddy of mine a couple months back. http://cgi.ebay.com/ebaymotors/ws/eB...tem=4545885659

the only thing they are good for is to drive slow and drift but i would still take my fc over the 240 any day of the week.

PerkyStina

I don't care... it's gotta be better than my 107 HP POS.

*Sigh* I want a decent daily driver, and a fun weekend car. This FC doesn't seem like it's gonna be either.

Dad just got home from a dinner meeting... so we're going to go to Advance again and test the starter. I think the starter fried this new battery too, but it's cool, cuz it's under warranty with Advance.

We'll see what happens... cuz I'm actually really attached to my car, and it SOOO sucks driving mom's van. I miss my car already. *Sigh*

I wrote a 7 pager on rotaries a couple of months ago. But thanks for this I may be able to use it j/k

capn

seriously guys i would really love some rotorhead input on this i love writng car articles and hearing the car guys and or girls opinion on it. who knows i may be a part time journalist

PerkyStina

I really liked it. I love writing, too... and I REALLY love taking pictures and doing designs and layouts. We should start our own magazine... and then make it MUCH more reliable and way cooler than RXTuner.

By the way, it wasn't the starter... just the contacts on the battery weren't connecting well enough from all the corrosion, so dad used some stronger cleaner on them.

I'm happy to get to drive my car again. It makes me sad to drive my mom's van when my car's not running. Glad that she's running again... and it wasn't a mechanical problem... just a battery issue.
