Not even close to true. My stock FD made less power than stock Corvettes and I was a lot faster than them on the track. My NA FB was even faster, but it wasn't stock. You cannot remove the driver from the race, or we wouldn't even need to have any races.Originally Posted by Catnip

I think you're missing the point. Your claiming that you out run sr20 powered cars in your rx7......... and im sure you do........
but because its an rx7..... not because its rotary. The argument isnt rx7 vs other nonrotary powered cars....
im not saying 240sx > rx7..... im saying (insert engine here) rx7 > rotary rx7. Id take an sr20 powered rx7 any day of the week over a rotary.

I'm pretty sure he's talking about drag racing.
Not that the driver doesn't matter there, but I would figure it would be a little less dramatic.
any racing............. an ls1 rx7 is a better car... better at everything. any track any where. leguna seca or the salt flats.... it's simply a better car.
rx7 is a great vehicle... legendary vehicle... worthy of all the recognition and praise it gets.............. but the engine is horse shit.

You're an idiot if you think that! LOL!
Tell me why there aren't that many V8 swapped RX-7s at the track then! Better yet tell me why there are hundreds of rotary powered race cars and even many times racing against V8 powered cars. You're basing that opinion on NOTHING and it's so wrong it's funny. Maybe the little street tuner crowd you seem to associate yourself with don't like rotaries, but in real racing, they're widely used and widely successful. Ever heard of Formula Mazda/Star Mazda? Those cars can run three seasons without even remotely rebuilding the engine.
Here's a stupid rotary for you:
I'm basing that on owning rx7s and doing v8 rx7 conversions. Driving them before and after. I'm basing it on years of being on rx7 forums and having conversations with people who also own rx7s and drove them before and after v8 conversions. You live right next door to hinson supercars.... you should know better.
Agree to disagree is all i can tell you. The next time i own an rx7 i'll let you know which dumpster you can find a rotary in.
I've had a bunch of them, and they have been a lot more reliable than a lot of other motors. They also made the car into a much more balanced machine than other motors. So, how is the motor poor? If you want low emissions and high mpg, get a 4 cyl Honda, not an engine that is ready to go racing. If you want an engine with torque to haul stuff around, get a truck with an lsx, not a little RX7.
An SR cannot maintain the same engine placement/weight as the 12a or 13b. NA - p-port 13b's are not really streetable, but will kill a built NA SR. A decent ported 12a can still make 200rwhp though, so still better in light car than an SR.
Turbo - I know of home-built turboed 12a's in GA that make over 650rwhp. Not exactly weak from a 1.1L.
Now - either engine can supply more power than a light chassis should need. HP is nothing without traction.
The OP has a clean FB with limited traction. There is no reason to change from rotary. Dropping in a 13B-T is the easiest swap for him to do. Get a TII, and everything pops in. Very easy way to put 250rwhp down with only a couple of mods. 250rwhp in a stock FB is a lot.

Wherever you read this, have a look at Jim Downing's builds.
Plus, in American IMSA history, Rotary powered cars have the highest winning percentage over any other power plant.
LAguna Seca btw.
Class specifications always benefit the rotary engine. You really think rotaries would win anything in a "run what you brung" environment?
Cool, I look forward to picking it up.
Last time I checked Hinson is in AL...lol. I do however live close to Downing, Team Spencer, Dempsey, and other teams that successfully race rotary powered cars.
Rotaries are typically heavily restricted so that's not exactly true. I recall an old tube frame 510 with a rotary in it that use to beat up on ex-NASCARs so...think what you like. lol
What is a run what you brung environment? What keeps me from showing up with a GE90? That's quite open ended as nowhere does it say i can't show up with JATO propulsion.
i see you'll discredit a rotary no matter what the circumstance. No matter how winning the result. They only place i'll give you a rotary is worse of then an American V8 is the expense required.
I seriously can't believe someone who says a rotary car having a racing class make specs specifically for it. In fact, most race organisers tried their best to keep a rotary restricted as much as possible. Never more so than 1991's Le Mans
In 1991 at Le Mans, the ACO did whatever possible to keep Mazda from racing the 787B. Only word from Jacky Ickx changed their mind. So they allowed the car to be built to Category 2 specification. Not the more current Category 1 with F1 derived engines. To add, all the Cat 1 cars would start at the front of the grid irregardless of where they qualified. So, the 787B started 19th even though it qualified 12th.
Competition for the 787B; the last 3 great Gr C race cars. Pugs 905, Sauber C11, and the fendered F1 car that was the Jag XJR-14.
Rotaries...banned at Le Mans since 1992.
JGTC in terms of GT500 or GT300?
GT500 requires facotry efforts and Mazda has never had one.
GT300. That car was built by Re Amemiya not a factory team as the issue with the GT300 is not engine but chassis choice. You can even race Daytona Prototypes against GT3s.
What under 2 liter racing are you talking about?
Me,
If is a Drag oriented car i will go with the LS V8 engine no doubt about it, also if is a play car a street machine, But if is going to be a dedicated road race machine i will do a P-Port 13B followed by a Hollinger semi-sequential trany, it will make a killer combo on a light first get RX-7 a complete track MONSTER,
But again that is my likes and preferences,
By the way i am building a 12A engine that i am doing a awesome Turbo Street Port and the side-housings after the port job will be lapped at Downing performance that is going to be in a street Toyota TE72 that is going to be around very soon, and as soon as my customer allowed me i will post pictures!
By the way, Simontibet, awesome video on that Rotary car at RA!

Never knew Downing did lapping or anything along the lines of engine work at all.

count me out of the "argument" for now, i may continue to respond at some point tonight..... but i tweaked my back today and in about 15 minutes im probably not gonna remember my own name.
I got an FB RX-7 yesterday from Aaron (Allmota) and it is awesome
Pic: Atlanta Spottings 6 | Facebook
Traded my EG hatch for it because he really wanted one. Back in the day he had a white EG hatch and came to the various gwinnett meets if anyone remembers. I also got a 78 corolla from him many years ago, Thanks a lot Aaron!
Nice, looks good.
The 787B was Banned from endurance races cuz the engine (AFTER RESEARCH) from FIA, FIA determine that the 4 rotor engine got more displacement than what Mazda claim it got, FIA said that Mazda got to count each and every side of each Triangle in the engine, mean 652cc X 12 to a whooping 7.824 liter displacement,
In Drag Racing The 3 rotor engine in the Modified Class got to weight the same as a Inline 6 Piston counterpart, also in the Full Chassis Class the same, the 13B 2 rotor need to weight the same as any 4 cylinder on both classes too,
And yes there is no race sanction that allowed a class like RUN WHAT YOU BRUNG, that is just non existent, unless is in Atlanta Motor Speed Way on Friday nights drag.
Also endurance races not always get won by the fastest cars, they do get won by the more reliable team, and hell yes the 400 Lbs. advantage play a big role on fuel savings and tire degradation!
SR20 Carbed Datsun B310
So given what we know.........
Mazda has 1 win ever in 24 lemans.
Mazda underrates their displacement to gain weight advantages.
Mazda's 1 win was with a 400lb weight advantage (note: cars only weigh 2200lbs)
The fastest Mazda qualified 19th.
Mazda won off fuel and tire management, not speed. Didnt post a single lap faster than runner up.
What is a more accurate statement to make?
A: Mazda's win is a black mark on history seeing as how they more or less cheated to win.
B: A clear example of rotary superiority to piston engines.
I like how you're singling out Le Mans as the only race that matters to the rotary now and ignoring results elsewhere. Did the SR20 or LS ever win Le Mans overall? lol
Like I said, the 787B winning Le Mans was luck, it wasn't because it was the fastest car, or the lightest, they just had better luck and kept a smooth race.
This thread is dumb, I already said I agree to disagree but you keep posting, you don't like the rotary, I do, we both agree they aren't God's gift to the automotive world, what else is there to say? lol IT'S A DAMN ENGINE WHO CARES?!?!?!
seems like you got shut down in your own argument now you're trying to end it.
that's smart though
if you can't beat him join him.
well......... unlike the 4 rotor mazda................. the sr20 is actually a production engine. I wonder what would happen if you added 2 more pistons to the sr20..............................................
you see where im going with this dont you?
my annoyance wasnt with you disagreeing with me. I welcome everyone to disagree with me. You keep telling me to "do research" before i post, you should know by now that i do.

Really? Because I ever argued about the 787B? lol....
There's no way to win an argument that started on opinions, I can't make him like what I like, so what's the point in continuing?
You clearly did research on the 787B, because the win at Le Mans was the only win they had that was controversial and luck. You never backed up any championships or series race wins. All this started with was rotaries are great road race engines with loads of success, I even said the Le Mans win wasn't really on my list of success as I'm the first to say that win was 100% luck.
You argue competition adjustments when the reality is EVERY car racing has adjustments to be competitive. V8, V12, V10, turbo 4 cylinder, doesn't matter, they all have adjustments. Typically rotaries face very tight restrictor plate restrictions and that was the death of rotaries in professional sports car racing aside from the GA RX-8s which will be done after this year.
In the end it doesn't matter, it's road racing, pick what you want to run with and race. If everyone ran V8s we would change the name...to NASCAR. I don't know what you were getting at with the SR20 thing, you're saying the R26B was an unfair engine because it wasn't a production engine? lol
Well basically yes and no,
They win with the rules as they where, as like any Mazda book they classified the engine as it just have 2 combustion chambers cuz they are like that but what they didnt say is those 2 combustion chambers share 2 rotors with 3 sides each, in a 2 rotor motor, thats why they are the 1.3 (13B) that consume Gas like a 3.9, go figure,
But Mazda did play the rules on that race fair and square, and they win legally, but the complains from the big $$$ competitors landed instantly like a 10 megaton BOMB and FIA did what they do the very NEXT race and the rest is History.
Toyota is doing a Big effort this year to get away with a Hybrid Car i hope they do have a win too, in Le Mans, but Audy and others have a very good Hybrid setup too, that is as good if not better, than the Toyota one, lets see what happen!

nice!!
Mater of facts the RB26DETT is not an SR20DT counterpart, that would be the CA18DET, what he meant was that an SR20 with 2 more pistons would be an engine Nissan never produce, like the Mazda 4 Rotor.

Gotcha, but what does that matter?
Nothing
Lol

Here they must use this one istead!
