I am amazed at how close minded some people can be about things. Especially things they are ignorant about.
Here are some of my favorites, b/c I know they are coming:
"But it the car doesn't handle like it's supposed to.. Yes it does. Why wouldn't it? The Buick V6 weighs the same if not less than the rotary"
"The cars 50/50 balance is now ruined! No it's not, and I think it's even lighter then when it had the rotarty (2960# now)." Yes I have A/C, PS, Heat, Stereo, Full exhaust, steel hood, all my seats, carpet and heavy TurboII wheels.....
"But the whole engine is in front of the front wheels and that makes it handle bad". No, sorry.. the whole engine is behind the front wheels which is great for handling and especially launching at the track....
"You took the 'heart' out of the RX-7 and destroyed the car!" It was a sick heart and I replaced it with a far superior unit..
Too bad you live so far away, I would offer a friendly ride in the car just to let you see the other side of the fence. BYOBVD's.
I am not here to convert anyone. Just here to clear my name as a 'rapist'...

You make me laugh dude. A rotary engine constitutes a "Sick heart"? Now, who's the ignorant one? You can beat Vipers, Mustangs, blah blah blah, your car is still a bastard child that doesn't belong to the imports or the domestics. If RX-7s are so worthless, then why did you bother to buy one? Oh yeah, because they look cool as hell, what does that make you?
The rotary engine is a great engine, a little primitive in its current form, but give it time. Do you honestly think your precious V6 was perfect from the start? Everyone knows that the piston (pissed-on) engine has been around longer, no wonder it's so much more reliable and fuel efficent. We can continue this debate when the Renesis becomes available in February '03.
I never said you ruined the handling, or added a lot of extra weight, all I said was that you raped a little RX-7. There is no denying that. Next time buy a Buick chassis.

By looking at your pic, I can see why you were banned from the other forum. Lol. That's a good one. Either way you are a funny guy, and I like your style.
Happy rotoring,

Give the rotory engine time and it will be perfect?
HELLOOOOOOOo its been around a looooooong time
and they still cant get it perfect, they can barely get the thing to run clean enough to import to this country.
And yes a buick V6 weights about as much as a NA motor, you people arm yourself with rumors and have NO facts to back your statements up.
Get a clue

"Barely get it to run properly"? Uh, ever heard of 247hp , naturally aspirated, out of 1.3 liters (Renesis)? Have you ever followed the GTU racing circuit? Have you ever heard of the 787B of the 1991 24hrs of Lemans? I think you need to get a clue pal.
I never said the rotary engine would be perfect, but believe it or not, time does improve the design of things. The rotary has been around awhile, but how many companies have been mass producing the engine? Only one. How do you think piston engines have come as far as they have in terms of fuel consumption figures and emissions standards? Trial and error, competition, ect.
Tell you what, I'll believe that a Buick turbo V6 engine weighs as much as an NA 13B when you provide the proper weight comparisons on paper. Have any facts to back up that statement? Prove your point not with just your opinion.....
Later,
Isaac

Typical response, instead of you yourself providing facts, you choose to tell me to.
Maybe your talking a difference of about 100lbs, not even, but even so the power-to-weight ratio FAR exceeds the stock RX-7 ratio. Who cares if you add 100, even 200 lbs when you are adding 150 ft lbs of torque?
You also wont need a rocket scientist to tune the car, too many think they can download a map from Hitman and have a 400hp TII on thier hands, its not that easy and too many people get in over thier heads and have a car that runs like CRAP.
Never mind, im not going to add to this mindless arguement, most of the board has 150hp N/A cars, and half to 3/4 of the turbo IIs arent running right or on thier 2nd/3rd engine.
Mazda is great, rotories rule, how silly of me.
Yeah, a GTU car is great, with factory support and millions of dollars of research, hardly compared to the cars we drive.

Yeah that's right I'm telling you to provide the facts. I stated that an NA 13B is lighter than a Buick turbo V6, you decided to argue that point. Logically wouldn't you provide some sort of facts to base your argument on? Possibly a weight comparison? Doesn't matter anyway, because you just admitted that you lied. I was right on that point and you were wrong, simple as that.
Very few people are stupid enough to think that downloading a fuel map for a 11-year-old car or older will yield 400hp. Well, maybe some people are that dumb. But at least they aren't so lazy as to swap out the rotary for a V8 or V6 because it is too complicated for them.
Yes Mazda is great and rotaries do rule. I agree with you there.
You were the one who said that rotaries all run like crap and can barely be made legal for sale in the U.S. So, I provided an example of rotaries that dominate in their respective race classes. Guess what Rob, those race cars wouldn't be around if they were based on street engines that hardly run or "run like crap". Obviously you were wrong on that statement as well, but no suprise there.

yea i would do the swap and its not definite but my car could possibly be the quickest in this whole thread and id still swap out my engine and trans to do an LT1 and t-56 swap just because i hate the lag sometimes...and flaming is for flamers...

V8 swaps can be much cheaper, and much more expensive than a 13bt swap depending on with v8 you choose. There are a number of companies out there that make bolt in swap kits, so the swap is not quite the task that some of you make it out to be. It shouldnt cost you any more than 2K dollars if you already have a good motor and trans. Keep in mind that the motor will still sit behind the front tires, and the motor still sits very low. Handling is hardly effected, and to some it is improved. My V8 powered RX-7 is still very confident around turns. It handles far better than I will ever need it to in a real world situation. Parts are readily available, they are cheap, and they don't break. Think about this for a moment. Say you have a stock chevy 350 okay(god I swear this is the last time I do this).
Take it all apart. Toss the stock cam, rods and pistons, heads, rockers, intake manifold and carb. Here is a list of parts that would gauranteed make over 400hp.
Holley 750 double pumper mech secondaries.
mmmm 76's for the front jets, 83's for the rear.(400)
Edlebrock RPM air gap intake manifold(200)
Stock casting GM double hump heads 2.02/1.60(400 bucks rebuilt)
Roller rockers(160 bucks)
3/8's screw in studs + machine work (100)
heads are done.
bottom end.
10:1 forged pistons. The size of the piston dome depends on chambers in heads.(200)
Chevy pink rods, which are basically LT1 rods.(150)
Any cam and lifter package you want you want(150)
I would suggest about 500 lift/294 duration. You can go bigger, but you wouldn't be able to run vacumm breaks.
A complete rebuild kit with High quality gaskets and piston rings goes for about 100 bucks.
Last but not least.... arp studs for the bottom end. 40 bones
Your stock pushrods should be fine.. if there are some bad ones replace them. They are only a few bucks.
Now put it all together(or have a competent shop do it) and break in the cam. This motor would make about 450hp anywhere between 6000 and 7000K RPM, and it would have enough torque to pull a tree down... not that I would suggest trying it in an RX7. Guess what else? It will last much longer than any 450hp rotary could ever imagine, and cost half as much as a rotary with that much power, not to mention be faster(torque).
You also have unlimited transmission choices. Anything from a 2 speed powerglide to a T-56. Sooooo...... For about 2500 dollars you can have a low 11 second street car, that handles better than 90% of the vehicles on the road. I know I left quite a few things out... and I applaud anyone who read this entire post.

V8 or not (my vote is to go for it too, BTW), I want to go for a ride in the jumpseat of that car of yours! Too bad you are day's drive south of here. I see it is all N/A with only functional mods . . . It looks very fast from your camcorder. Aaaah, the potential of a light, simple RX-7!

bah i had this long spiel going, then my computer crashed. ****.
Basically <sigh> (i hate retyping) i'm on the fence on the issue. On the one hand, yes rotaries are cool (im an engineer major and thats most of the reason i got one in the first place) but then again, v8's make monster power. for a lot cheaper. I was planning on dumping 8-10k into the rex this coming summer for a N/A-TII swap, them mod it with a new turbo, fmic all that ****, but for that amount of money (less even) i could pull a lost more horsies from a v8. And i am looking for raw power. oh yeah. I also said if i had my choice, **** chevy 350, i'd go with a ferrari v8 (4.something litre?) or a 528 hemi block. But those are expensive (13k just for the 528). Anyway i was considering a V8 swap as one of my options, but i really dont like the idea of spoiling the rotary motif of the RX-7. Heck, the rotary even got me out of losing my liceance for 6 months a couple weeks back. (long story) anyway, i have quite a few months to think about it. hmmmmm....

oh yeah, BTW, i had to point out that people are making moot points. I love rotaries too, but i can face the fact that they are thermodynamically INEFFICIENT hand have noooo torque. And guess what. You can't change it.
But there is a counterpoint in time... piston engines have been around since what, the 1890's for gasoline powered? you can count the 1860's if you wanna do steam (iirc) and rotaries... production rotaries have been around since the 1960's. So the piston engines have had a lot more time to become more perfect. but the rotaries have come far in their little time, and they can still go a lot farther. Look at the new renesis. Pretty nice.
My point: In time, rotaries will become more effiecint and powerful, but they will never ever catch up to piston engines because of physics. Simple as that.

Hey, go for it. If you can get a 350 turbo 3 speed slap shifter. It will be the absolute fastest damn car you will ever have the glory of wrecking. You will need to cruise over to mazdatrix and buy a strut tower brace w/ firewall supports. You should also do a roll cage to keep your chasis from twisting. You will gain engine weight but lose **** weight that is attached to the rotary. It would be better to go with a ford 302 because it only weighs 100lbs more than the 13b motor to motor but since you don't need all the other BS you need on the rotary you only gain 40lbs that can be lost other ways. Go for it. Have fun but be careful damnit. it will be easy to wreck that car.

Many big name companies, companies like GM, said the rotary would never be production ready. A little Hiroshima company named Mazda proved them wrong in the seventies, and some day they might prove you wrong as well.
Nobody knows for sure, but I have faith,

yes, they are mechanically efficient, and so they are an awesome design....as pumps. Not engines. Fact of the matter is, engines burn gasoline, to make a pressurized gas, which also creates heat, yadda yadda. That's thermodynamics. Rotaries are bad at thermodynamics. The professor gave them a D- in thermodynamics. There really isn't much you can do to make them more efficient. You cant really fool around with the shape of the housing. You can play with the shape of the rotor a little, but any change you make will have as big of a setback as it does an advantage. The apex seals are a real weak spot too. They also have a tiny "Stroke" if you will. That's the reason they have **** torque but high horsepower. They don't do much work, but what they can, they do it ****** fast! That more or less is the definition of the relationship of torque to horsepower. Prolly why i got sorta beaten by a pickup truck today (well, he just took off from behind me without warning, and i was already in third, but it was ****** hard to catch up)
Anyway if a guy wants to drop a V8 into his 7, bones to him. Why is it such a crime to be different? Maybe these guys LIKE the fact that the pisst-on (hehe) engine makes a crapload more torque and will pull on you. Who knows. But I dont see why you guys should flame him. Internet invicibility i suppose.

(oh yeah, and the low amount of torque a rotary has by design can be overcome by its incredible response to turbocharging)

Yo Isaac,
When is the Renesis motor going to be available to buy? Or is it? I want to swap one of those into my 87 some day (if I don't crash the car in the meantime).

I never thought that a V8 RX-7 was "run of the mill' but ok. And no one said its easy to swap one in, its just a lot cheaper, a hellova lot cheaper than doing a 20b conversion.

I never said the swap was easy, but it's easier to make power out of a V8 than it is a rotary. Less brains are involved.

Hey I got a question for you v8 guys... Can the rear diff handle the abuse? It seems like a waste to have all that torque and have to replace the drivetrain everytime you do a hard launch. The tranny may handle a modified V8, but I'm not sure how the Mazda driveline would fare. Afterall, you would be pushing more hp and WAY more torque through the driveline than the Mazda engineers ever expected. Also, I would think that you would be required to run super wide and sticky tires out back to make use of all that torque, thus compunding the problem even further.
This is not a flame. I'm just looking for info from the guys about this situation.

As for the above weight argument between the two motors... who really cares. Like I said, my car weighs in at 2960# and that is with A/C,Heat, Power Steering, FMIC, Trans cooler, steel hood, Turbo II wheels (heavy), 57# battery, SS exhaust and as usual my tool bag, laptops, helmets ect. The car hasn't had one single thing removed from it in order to 'save a few pounds'. For example it has all the carpet, seats, interior pieces, stereo, sunroof, power antenna and whatever else came factory on the car in 1987.
What does a STOCK '87 SE weigh?? Says here: http://www.mrccfl.com/2nd.html that the curb weight was 3000+ pounds. How did I lighten the car by adding a heavier motor?? EVEN if it added a whopping 100# (which it didn't) I have tripled the horsepower and quadrupled the torque of the almighty rotary! We share some of the same interests as the Buick guys are proud of producing 500HP from a 3.8 liter motor.
