To get an rx7 in to the 9s or even 8s isn't as hard as you think...wed redux...a TII that weight 2300-2400lb with 400 rwhp, with a 4.30- 4.44 final gear, big enough slicks and the right differential your there, (well with the help of a stanalone with a 2 step launch program)

I think that's kind of the point. I have driven a 600 hp supras and they arn't as tempermental on the street as a 250 HP RX7. On the highway and track the 7 can shine. But when you start to approach 150 MPH it gets nervous. The supra feels home at those speeds IMO. Which could make the supra a contender for the best all a round sports car. Big street happy horse power, and at home at higher speeds.
When comparing stock cars. It's tuff, I'd say it comes down to personal taste. Both are a blast to drive. I personally like the n/a sort myself. More fun with no turbo lag.
Once you start talking about after market, there are too many variables. One person might like the way this set feels for his driving. he could be inexperienced at seting up a suspension. It could be done incorectly for that type of driving, or just worn out.
I'll bet that the right person could take one of each car and get the same lap time and similar track speeds in both.
But you can't get 800 out of a wankle. no getting around it. And even if you can, you can't get the groceries with it.
I've had seven toyotas, supras and Celicas (RWD). Now I have five 7s (counting the one I bought for my girl). I would buy a Toyota again, I'd also buy a Nissan again. But I will always have at least one 7.

Second time on first list was made w/ a tube chassis Rx-7 driven by Abel Ibarra. That 7 only made 758hp. But it also weighed next to nothing. It was a two rotor also.

That is why rotaries and 2-strokes make such large amounts of power for their size.

My appoligies to Cool. The way you put it is true. A 2-stroke does breath twice as much air as an identical 4-stroke engine at same capacity & rpms.
I understood his post wrong.
My point was that We can't put a 200cc 2-stoke engine in the 400cc class. There are many other factors involved in engine efficiency. People need to realize that there are advantages, and disadvantages to certain engine designs, that's why we have many different types of engines, it depends on how we use them.

I don't get what you're saying. Why does a 1.3 liter 13bt make more torque than horsepower then? I'm not trying to attack your post, I just don't understand it. If you could explain it to me, I'd appreciate it.

because of that last letter on that engine code. take ito ff and your torque will be poopoo

err, I thought that the eccentric shafts offset from the housings central axis is the reason we have shitty all around torque. (Uh, is that why we call it displacement?) Not just in the low end, but accross the entire band. Its the power/energy that is not wasted on an up-stroke plus all those crappy cams and lifters in that of a piston engine that allows for incredible HP in a rotary.
So I would think that piston engines allways have the torque advantage by design of how far the piston's arm
travels because it would seem to me it travels alot further than a rotary.
So torque is always for the most part gonna suck in stock 13b's
But, I donno, just what I think. Trying to differentiate torque from power is melting my 1hp brain right now.

Torque is work. horsepower is power...
basically.. power = how fast you can do a certain amount of work. The whole trick to make more use of your power is to do less work, move less weight. IIRC, back in the day, 1hp = 500 pounds 1 foot in 1 second.
Since our cars are not exactly known for their torque numbers, you gotta make the engine work faster to make up for it.. kinda like.. keeping it in a lower gear, but all the time..
Ok, i've drank way too much tonite. i'll try to explain this better tomorow

Imagine the money they spend on it though.
Also, thers a Drag RX-8 gettin built that supposedly has 1300hp but i dunno if its on 2 rotors, but it might to be using the RENESIS, so.....

Isn't Abels new car (RX8) powered by a 13b? I think they said they were shooting for 1400hp this year.
Last years stuff:
Engine: 13B REW 1.3-liter turbocharged on methanol
Sponsors: K&N Filters, Toyo Tires, Extrude Hone, Mazda
Best e.t.: 7.12
Best speed: 178 mph
Career highlights: 2000 NIRA Pro Import National Champion
2000 IDRC Pro Import National Champion
Mazda world e.t. record holder
NIRA Pro Import speed record holder (172.27 mph)
Here is what I was originally looking for :
With more than 1400 turbo charged horsepower, the new RX-8 should easily run passes in the 200-mile per hour range. Ibarra added, "this is going to be the hottest car in all of NHRA Sport Compact Racing!"

Id take that bet. Make it $200 though, i need a few parts.

ROFL!
As for the new RX-8 dar car, it is supposed to be 1400 estimated turbocharged renesis! that will be one wild car... I think! Can't wait to see what she does... then I cannot wait to see what the new RX-7 if there ever is one... will do also!

the new RX7 is supposed to come out in 2005. My friend works at Mazda and says he heard that its supposed to be 4 wheel drive and 300hp NA. Only way i see that is a 3 rotor.........

But I have plans to change that. I'll never see 400 hp in the Sentra like I will my next FC.
