if you cant get to it, its just a random post from someone on carolinahondas.com...
"first you got them coming out and being overrated, then the recall shit from Mazda, now im going down the interstate yesterday and see a gray one being pulled by a wrecker...no, it wasnt wrecked, either broke down or repoed. well, today im riding down highway 11 and see a blue one on the side of the road w/ the hood popped open and homeboy sittin there acting like he knows what he's looking at while talkin on the cell. sux for the people buying these...looks like they paid 32K for a car that just handles good. oh well."
just a little interesting to me..

Frankin7 10-09-2003, 11:45 PM yup, they've had lots of problems. they had to drop the HP from 250 to 235 to pass emissions and now they're breaking on them. doens't look good for Mazda.
rxtasy 10-10-2003, 06:43 AM There's been posts on the rx7club board about Mazda buying back these cars. So apparently they're not what they've been made out to be. I'd get one without the engine and put mine in it.
Frankin7 10-10-2003, 12:07 PM i'd try to put the 13brew that COsborne has into one. it would be real quick then.
id rather put it in a rx3 or cobra kit car.
Frankin7 10-10-2003, 11:08 PM those might be pretty interesting to see with a 13b-rew in.

marshall was telling me a few weeks ago that these cars are just a test bed for the up-and-coming rx7. Just to see what goes wrong, and how to improve on it. It must suck to own a guinea pig...oh wait...DAMN IT!

thats BS ........... theres no way mazda would sell a 35k dollar car as a guinea pig.... first off, there would be lots of lawsuits involved.. no way thats true. the renisis engine just dosnt have teh reliabality to pump out 250 hp w/o breaking. imo, there is a good chance the rx8 will kill any project funds for any more rx cars to come.
Frankin7 10-11-2003, 12:39 AM i was under the impression that the new rx7 was already almost done developement and was to be released for the 2005 year.
Stegall 10-11-2003, 11:11 AM if the rx8s flop, and the Mazda has to spend alot of money repairing this things or what ever, it will kill the market for the new rx7
Cosby 10-11-2003, 11:43 AM They should have learned from experience. Just as with all of the other RX-7s the RX-8 has the rat's nest on top of the engine. Happen to know what tends to break on rx-7s? Oh just everything in the rats nest. Better engine management would be the key here...
Chipster 10-13-2003, 08:09 PM cobra kit car with a 13B... haha that would be very unique.
There's a color changing snake with a viper engine in it. Im sure you guys have seen it in mags and shit before

N1XRR 10-14-2003, 09:55 PM Time to clear up a few things:
#1. There has been no "recall" on the RX8. What you mean is the buyback or free service + $500...
#2. Why did this happen? Because Mazda, by US law, is required to rate an engine AS IT IS SHIPPED FROM THE FACTORY. The RX8, just like the 2nd and 3rd gen RX7's have a 20,000 mile switch that activates a 2nd fuel/ignition map. This is put in place to break in the engine properly.
#3. It is well known that Mazda reprogrammed these cars when they got on the docks in the US...why did they do that? Because they spent a long time testing the durability of the engine and when the original design was made the emission laws had not changed yet, nor have they now. Mazda made the car compliant with the 2006 California emission laws. What does that mean? Instead of reaching operating temp in 10 minutes or less and the emission system being required to last for at least 8 years, it was changed for the car reaching spec in 5 minutes or less and emission systems lasting for 10 years or more.
But, why did they have to change anything? Its well know that the rotary has HOT exhaust gases, so to preserve the catalytic converter they added more fuel, cooling the mixture.
#4. These cars cannot be dyno'd like a normal car. When the computer see's the front wheels not moving and the rears going 100mph it thinks there is a problem and pulls timing...BIG TIME.
#5. Even with the timing pulled it is VERY well documented to-date that these cars have already gained 20+ rwhp just by breaking in.
#6. There has not been much modifying the cars yet, but a few have. One person in Canada found a 45 HP GAIN BY FUEL ALONE! This car is VERY underrated. With some ignition changes we will see 280hp EASY, and with exhaust....you get the idea.
#7. There have been a few small problems here and there. The oil pressure/temp sensor messing up and CEL light going off, but thats to be expected in a first year car.
These cars are actually doing fairly well. Go to John Finger Mazda once a week for 4 weeks...you won't see the same RX8 twice...they are selling really well. Why do the dealers have so many? Mazda wanted to meet demand so they produced more then originally intended.

Mike, you make very good points. I saw for myself just today where a guy who wasn't even finished tuning gained 45 hp with fuel adjustment alone on a mustang dyno (stock exhaust, intake, etc). I assume that is the guy you're speaking of. Thats pretty impressive, however there WILL be vacuum issues. I promise you that. Just take a look under the hood of one.
N1XRR 10-15-2003, 10:34 PM Actually, the N/A RX7's never really had a major problem with vacuum hoses as they didn't have all the heat because of the turbo. Every single 1st gen RX7 I've worked on(5 or 6 now) and N/A 2nd gen(2) has all had very good original vacuum hoses. Plus, the RX8 has silicon...or thats what they looked/felt like on the display model.
Cosby 10-16-2003, 01:43 AM The NAs Ive worked on have all had extremely brittle lines that any redneck or amature mechanic would easily crack or break a seal to. On all the 2nd gens I've noticed the lines to the area around the ACV (including the pressure sensor line) are generally cracked or leaking. If theyre silicon I'd be quite impressed. I really hope they are, that would be a great step in the right direction. I understand why all the lines are necessary but they should have made a seperate model for california. My car has like two or three vac lines at most but I couldnt dream of the car warming up in less than 20 minutes at idle lol.

Your quite right, the ones directly above the exhaust manifold are brittle quite often...but its not ANYTHING like an FC or FD turbo where there are ALWAYS vaccuum problems
Frankin7 10-16-2003, 08:16 PM N1XRR, i saw you today on my way home from work!! it was at the corner of wade hampton and 14 i think. i was stopped at the turning light and saw a TII and was like, theres a -7-, wait a min. its got a hood scoop! damn its a TII!!! *drool*
its cool to know it was you :D
if you wanna meet up sometime that would be cool!
Cosby 10-16-2003, 11:31 PM you sure it was an AE? may not have been mike.
Frankin7 10-17-2003, 08:01 AM i'm almost 100% it was him. it was a white TII with the same tail lights. there are no other TII's i've ever seen around here.
i was going to buy a red one but the guy who had it was an ass.
Stegall 10-17-2003, 10:12 AM I dont think it was Mike... Im pretty sure his 7 is still out of commission... There are several white TIIs around greenville and ive seen 1 other AE besides mike. Theres even some guy that has a white NA with a TII hood on it.
Cosby 10-17-2003, 11:33 AM mike's is running
is that the guy u raced in greer then your turbo was glowing?
Cosby 10-17-2003, 12:53 PM yup, sure was
Chipster 10-17-2003, 01:41 PM there once was a pristine 40k mile TII that i saw for sale in the Greenville Classifieds. It was the 10th AE version too. could it have been this one?
Cosby 10-17-2003, 02:01 PM nope, not it
N1XRR 10-17-2003, 06:15 PM That wasn't my 10th Anniversary Edition you saw...but I do know the person selling that 40k perfect condition one. The day after I bought my car someone from down the road where I used to work came and talked to me, he had one and I was amazed to see it was just like it rolled off the showroom floor. Absolutely amazing car, nice guy to...
Just to let you know, there are actually 8 10th Anniversary Edition RX7's in the Greenville area. I've actually talked to 6 of them.
My car current isn't registered and is at Greg's place. Running now, but needs a new boost sensor(mine was going CRAZY reading 4 PSI at idle)
Frankin7 10-18-2003, 07:14 AM oh i see, well i hope you can get your TII on the road pretty soon.
Stunna BEN 10-19-2003, 09:31 AM I just have to add this...

Baseline I get on a Mustang Dyno is around 178HP (cold) and about 172 after some runs and heat buildup.
We did some more runs today, and started working on the midrange section, between 3700 to 6200
These are the areas where we run 4 out of 6 intake runners.
Surprisingly enough there is HP to gain in those ranges as well.
At the 6200+ we see it running way rich.
At 3700 to 5500 it is actually running too lean, which surprised me.
With a bit more fuel and some minor adjustments we are gaining 15HP in there as well now.
More importantly we see a gainof nearly 20 ft/lb of torque at 5000rpm.
We just started setting up the ignition controller, and will do some tests and runs on that tonight and tomorrow.

We are up an additional 12HP by raising the timing 1.5 to 2 degrees at 6200rpm and up. We are avoiding adding advance below 5,000 as that is the range you would risk knocking.
Although with the enrichment we added in the midrange it is still pretty unlikely..
That is 45+HP gained at 8000rpm, and most interestingly up 32HP at 5700, which is roughly the torque peak point. Torque was up 26 ft/lbs as well at 5700.
So that ends up being 178hp + 45whp = 223whp on stock intake and exhaust!
That's pretty damn impressive.
