New and Confused
Ok hi every one, recently bought a RX7, the guy said its an N/A if that helps
Its a strange car in the fact I have never seen one before I bought it, but It drives real nice.
I popped the hood to check the motor when I got It home and it looked strange, Took me and my bros ages to find the spark plugs and there on the side??????
and in like a box formation, does that mean its a boxer engine, or V4??? I cant figure it out. And on here everyone keeps saying Rotary engine, isn't that what 747 jets have.
I want to customize it with body kit, rims, big speakers and really low. I have never done anything like it but I'm a quick learner, first I'm getting a bass speaker then a trunk mounted wing.

Wow, please, read the FAQ, and also read this
http://www.rotaryengineillustrated.c...orks/index.php
As for your body kit and lowering, there is plenty of info in the FAQ, please have the pieces painted and fitted professionally or your car will look like crap. You should get pretty low with some cheapo D2s or Ksports but you will sacrafice handling that way.

Roatary engines are on jet planes.
Have fun with your car but do know rx7's need good up keep if you want it to last. If you put a speaker box back there the rear hatch will rattle really bad. I put some foam inserts so it doesn't rattle. Have fun with your new 7 and welcome to the club

Failed....
Do yourself a favor and sell the car if your just going to rice it out. A rotary engine is a rotary engine... No pistons...
Also have some money laying around, since your going to be needing it. Do a full tune up, go read the faq. Do some research... It will help you a lot.

This is my first own car. and I already love it, think it does need a tune tho as it sounds rough and noisy.
The car cost $2000 and I have $2000 for mods etc, so ordered some speaker and the bass box is being bought for me by my girlfriend. And Getting a big carbon-look wing, it will be sick.
If a rotary has no pistons how does it do anything, it must have all engine have.

It must get real good gas mileage with that design, seems loads better than pistons. why dont all car have this with the environment stuff thats going on.

Invest in a haynes repair manual and read thru it, it will help you out. Also search through the site extensively and check out the FSM available on the site as well.

The rotary tends to get worse fuel mileage due to the long shape of the combustion chamber and the fact that it fires more often then an equivalent displacement 4 cylinder.
This is partly also the reason why it's hydrocarbon output is so high and 3 cats are required (as well as an airpump) to clean up the exhaust. The other half of that story is the overlap between intake an exhaust, which pollutes the intake charge a little at low RPMs and results in an incomplete burn.

SO EGR is very usefully used to lower emissions on both Spark ignition and Diesel engines, who knows the chemistry of what is happening but It is a proven technology and method. dilution due to overlap is essentially a form of EGR, exhaust gas is introduced into intake charge. So why so detremental to emissions?

Is this guy serious ? 
Can't say much on the kit/wing/speakers but its your car...
However I would get the car checked out before you drop a bunch of money on extras make sure it runs well
+1 on the haynes manual if he wants to do it himself or do a bit of learning

Yeah I don't know if these are real questions..but welcome to the 7 club. Alot of **** to be learned on here.. and just read read read. Search for any questions you might have because, surely somebody has asked it before. Lets see some pics of the 7..

Everyone, enough with the troll reports. Maybe he is trolling. Maybe he is a new user who needs some guidance (with less then 10 posts, this is likely). He would not be the first to have bought an RX-7 knowing nothing about it.
If he is trolling, then the thread will die shortly as we won't be feeding him. If he is not trolling, then you guys are just looking like jerks and discouraging a new member from learning.
EGR is used to lower combustion temps and thus control NOX output. It is a controlled recirculation of exhaust gasses with flow tailored to engine load. Overlap on the other hand is uncontrolled flow, generally increasing as RPMs decrease and thus being able to pollute more of the intake charge during a time when EGR is typically totally shut off.

Aaron you went to school didn't you? I wonder what you dont know about Internal Combustion. I do feel the Rotary has got years of development to go (oil dependant) to refine the design and address problems that I feel do have solutions, trouble is lack of rotary competition, if only another manufacturer took it on too.

Mazda has been working on the combustion chamber shape issue and the new 16X rotary has been reshaped to correct it. They've gone with a thinner housing and a longer eccentricity to make a longer "stroke" compared to the 13B. This produces more torque and allows the port placement to be tweaked a bit, meaning larger ports without the risk of overlap. The Renesis of course moved the exhaust ports to the side housing to almost totally (or totally?) eliminate overlap.

Well, technically I didn't the first time and had to retake a math course during an extra winter semester. I hate math. It's too boring to waste effort on.
But anyway.... Back on topic.
